The garden store was able to sell a total of 1,960 bags of potting soil on Saturday and Sunday.
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
In order to find the number of bags of potting soil sold over those two days, the first step is find out the number of pallets store sold there potting soil :
= 17( on Saturday) + 23 (Sunday)
= 40 palettes
Each palettes has 7 flats so the total number of flats sold is:
= 40 x 7
= 280 flats
Each flat then contains 7 bags so the total number of bags sold is:
= Number of flats sold x 7
= 280 x 7
= 1960 bags
In conclusion 1,960 bags of potting soil were sold.

Answer:
Distributive Property of Multiplication
Step-by-step explanation:
The Distributive Property of Multiplication states that multiplying a number by a group of numbers added together is the same as multiplying each number separately:
[tex]\large\text{$a(b + c) = ab + ac$}[/tex]
Therefore, applying the Distributive Property of Multiplication to the given expression:
⇒ 5 × (10 + 7) = 5(10) + 5(7)
--------------------------------------------------------------------------------------------
Here are the definitions of the other properties for information purposes:
Associative Property of Multiplication
The grouping of numbers by parentheses in a different way does not affect their product.
[tex]\large\text{$(a \times b) \times c = a \times (b \times c) = (a \times c) \times b$}[/tex]
Identity Property of Multiplication
This property is also known as the identity property of one.
Multiplying any number by 1 does not change the number, i.e. the number keeps its identity.
[tex]\large\text{$a \times 1 = a = 1 \times a$}[/tex]
Commutative Property of Multiplication
Changing the order or position of two numbers does not change the end result.
[tex]\large\text{$a \times b = b \times a$}[/tex]

On Saturday, some adults and some children were in a theatre. AC
The ratio of the number of adults to the number of children was 4:3.
Each person had a seat in the Circle or had a seat in the Stalls.
of the children had seats in the Stalls.
114 children had seats in the Circle.
13
There are exactly 1100 seats in the theatre.
On this Saturday, were there people on more than 70% of the seats?
You must show how you get your answer.
If 114 kids were seated in the stall, just 21% of the seats were filled.
If 117 youngsters were seated in the circles, then yes, more than 60% of the seats were filled.
A third of the kids were seated in the stalls.
if there are 117 kids who can fit in the stalls.
Given that 3/4 of the children had chairs in the stall and x children, we have:
3/4*x = 3/4x.
There were 117 kids in the 3/4 portion.
= 3/4 of x = 117
= 3x/4 = 117
3x =117 x 4
3x = 468
x = 156 kids overall.
39 kids sat in the circle, compared to 117 in the stalls.
The number of adults to children was 5:2, which equals 5+2 to 7.
Use the ratio of children to represent as y and the total number of individuals to determine. So, here we are
2/7 of y = 156
2y/7 = 156
2y = 156x7
2y= 1092
y = 546
In all, 546 persons are present, and 546 of the 2600 seats are occupied by them. We now have:
546 / 2600 = 0.21 = 21%.
If there were 117 kids in the circle, there would be 117 x 4 = 468 kids (total number of children)
Consequently, considering the ratio: 2/7 of y = 468 = 2y = 468x7
2y = 3276
y= 1,638
There are therefore 1,638 individuals present in all, and 1,638 of the 2600 seats are occupied by them. We now have:
1638 / 2600 = 0.63 = 63%.

why do you get different answers for -5^2 and (-5)^2. And why is one positive (33) and one negative (-18) !!
Answers to both the given expressions are the same that is 25 and both answers are positive.
What are exponents?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal 23.Product of powers rule — When multiplying like bases, add powers together.When dividing like bases, apply the power quotient rule.Power of powers rule — When raising power by another exponent, multiply the powers together.So,
-5² = -5 × -5 = 25Similarly,
(-5)² = -5² = -5 × -5 = 25Hence, we can say that the answers to both the expressions are the same and both have positive answers.
As, when we take a square of any negative number, after the multiplication the results always come positive.Therefore, the answers to both the given expressions are the same that is 25 and both answers are positive.

In ALMN, l= 97 cm, m = 52 cm and ZN=39°. Find ZL, to the nearest degree.
Answer: In ALMN, l= 97 cm,
m = 52 cm,
ZN=39°,
ZL= 66°
Step-by-step explanation:
Given data,
In ALMN, l= 97 cm, m = 52 cm and ZN=39°.
The law of cosines can be used to find the missing side.
n² = m² +n² -2ml·cos(L)
n² = [tex]52^{2}[/tex] + [tex]97^{2}[/tex] - 2(52)(97). cos (39°)
n² = 9409 + 2704 - 2(52)(97). cos (39°)
n² = 12113 - 2(52)(97). cos (39°)
n² = 12113 - 10088 cos (39°) (eq - 1)
So, that cos (39°) = 0.777
Substitute cos (39°) value in this equation 1
So,
We can write,
n² = 12113 - 10088* 0.777
n² = 12113 - 7838.3
n² = 4274.62
n = √4274.62
n = 65.38 ≅ 66
Therefore,
In ALMN, l= 97 cm,

Answer: The LARGEST angle has a measure of
degrees.
The LARGEST interior angle of the triangle has a measure of 92 degrees.
What is the largest angle of the triangle?The sum of the interior angle of a triangle is 180 degrees.
Given the data in the question;
Let x represent the measure of the first two angles.
Since they have same measurements.
Measure of angle 1 = xMeasure of angle 2 = xMeasure of angle 3 = x + 48Since the sum of the interior angle of a triangle is 180 degrees.
m∠1 + m∠2 + m∠3 = 180°
x + x + x+48 = 180
3x + 48 = 180
3x = 180 - 48
3x = 132
x = 132/3
x = 44°
Measure of the largest angle will be;
Measure of angle 3 = x + 48 = 44 + 48 = 92°

A model rocket is launched with an initial upward velocity of 39 m/s. The rocket's height / (in meters) after t seconds is given by the following?
For t = 0.8 seconds and t = 7 seconds, the height of the rocket will be 28 m.
We are given that:
Initial velocity of the rocket = 39 m / s
Time = t seconds
h = 28 m
The equation of relationship between height and time is given as:
h = 39 t- 5 t²
Substituting the value of h is the equation, we get that:
28 = 39 t - 5 t²
5 t² - 39 t + 28 = 0
Using middle term splitting to find the values of t, we get that:
5 t² - 35 t - 4 t + 28 = 0
5 t ( t - 7 ) - 4 ( t - 7 ) = 0
(5 t - 4 ) ( t - 7 ) = 0
5 t - 4 = 0 and t - 7 = 0
5 t = 4 and t = 7
t = 0.8 and t = 7.
Therefore, for t = 0.8 seconds and t = 7 seconds, the height of the rocket will be 28 m.

Determine which region has the absolute advantage for sheep production. Explain your answer.
Because food grows more quickly in the hills when exposed to heat and rain rather than sunlight all day. Then for 1 sheep 1 bushel is required in the hills.
What are statistics?The practice or science of organizing and interpreting numerical data in big quantities, particularly for the objective of concluding proportions in a whole from those in an expected sample.
Given that a remote agricultural nation is divided into two distinct geographic areas: a lowland plain and an upland of rough hills. A farmer can grow 10 bushels of grain or pasture 10 sheep on one unit of land on the plain. A farmer in the hills can pasture 4 sheep or grow 2 bushels of grain on one unit of land.
As opposed to being exposed to sunlight all day, food develops more quickly in the hills when it is exposed to heat and rain.
For uphills = 10 sheeps = 10 bushels
For uphills = 1 sheeps = 1 bushels

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,1100,2,203) = \frac{C_{203,0}C_{897,2}}{C_{1100,2}} = 0.665[/tex]
For item c, the probability is:
P(X >= 0) = 1 - P(X = 0) = 1 - 0.665 = 0.335.

To find a baseball pitcher's earned run average (ERA), you can use the formula El=9r, in which E
represents ERA, I represents the number of Innings pitched, and r represents the number of earned runs allowed.
Solve the equation for E. What is a pitcher's ERA if he allows 15 earned runs in 36 innings pitched?
If necessary, round your answer to the nearest hundredth.
The equation for E is E= _____?
If a pitcher allows 15 earned runs in 36 innings, then the ERA= ____?
The value of the ERA is the 3.75.
According to the statement
We have to find that the value of the ERA.
So, For this purpose, we know that the
ERA is the number which represents the average number of earned runs given up by the pitcher per nine innings.
From the given information:
First, we are given the formula E * i = 9 * r.
Second, we are asked to resolve for E. If i doesn't equal zero, then we are able to divide both side of this equation by i. (Note that i = the quantity of innings pitched, which isn't zero.) We then have the equation E = (9 * r) / i.
Third, we are given some numerical values for our variables, and asked to use this equation to unravel for E.
Substituting r = 15 (earned runs allowed) and that i = 36 (innings pitched) into the equation and that we have
E = (9 * 15) / 36 = 3.75 (rounded to the closest hundredth)
So, The value of the ERA is the 3.75.

Debra runs 4 miles in 30 minutes. At the same rate, how many miles would she run in 48 minutes?
========================================================
Work Shown:
(4 miles)/(30 minutes) = (x miles)/(48 minutes)
4/30 = x/48
4*48 = 30x
30x = 4*48
x = 4*48/30
x = 6.4
