Answer:
y = -4/9x + 44/9
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
m = ( 8-4)/( -7-2)
= 4/-9
= -4/9
The slope intercept form is
y = mx+b
y = -4/9 x+b
Substitute a point into the equation
4 = -4/9 * 2 +b
4 = -8/9+b
36/9 = -8/9 +b
Add 8/9 to each side
36/9 + 8/9 = -8/9 + 8/9 +b
44/9 = b
y = -4/9x + 44/9
Grains of sand are very small, there being about 3000 grains in one cubic centimeter (cm3) of sand. A cm3 is a small cube measuring one cm on each side and is about the size of your little finger from the fingernail onward. Given that there are one million cubic centimeters (cm3) in one cubic meter (m3), how many grains are there in 1 m3of sand
Answer:
The value is [tex]x = 3.000 * 10^9 \ grains[/tex]
Step-by-step explanation:
From the question we are told that
[tex]1m^3 = 10^6 cm^3[/tex]
And that
[tex]3000 \ grains \ of \ sand \ is \ in \ 1cm^3[/tex]
So the number of sand grain that is in [tex]1m^3[/tex] is mathematically evaluated as
[tex]x = 3000 * 10^6 \ grains[/tex]
=> [tex]x = 3.000 * 10^9 \ grains[/tex]

35,892 rounded to nearest 10
Answer:
35,890
...........
Answer:
35,890
Step-by-step explanation:
The 9 is the tens digit.
Every digit to the right of 9 becomes 0.
Start with: 35,890
Now you check the first digit to the right of the tens digit. If it is from 5 to 9, the tens digit goes up 1. If it is from 0 to 4, the tens digit remains the same.
In this case, the digit to the right of the tens digit is 2. Since 2 is from 0 to 4, the 9 remains as is and does not go up by 1.
Answer: 35,890

2 to the Third power -(30÷5) +9
Answer:
11
Step-by-step explanation:
2^3-(30/5)+9
First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
so 30/5 = 6 and plugged in is:
2^3-(6)+9
Next, we do exponents:
2^3 = 2x2x2 = 8
plugged back in:
8-(6)+9
Now, we do the math from left to right so:
8-6=2
2+9=11
11 is your answer
Perform the operation.
(–2x2 – 2x + 1) + (-8x2 – 7)

Problem 1 (3 + 3 + 3 = 9) Suppose you draw two cards from a deck of 52 cards without replacement. 1) What’s the probability that both of the cards are hearts? 2) What’s the probability that exactly one of the cards are hearts? 3) What’s the probability that none of the cards are hearts? Make sure to clearly define your probabilistic events and mathematically show how different probability laws and rules that you learned in class could be applied to solve the problems.
Answer:
0.0588235; 0.3823529; 0.5588235
Step-by-step explanation:
Given that:
Total number of cards = 52
Total number of hearts = 13
Probability = required outcome / Total possible outcomes
Two cards are drawn without replacement :
1) What’s the probability that both of the cards are hearts?
First draw :
P(hearts 1) = 13 / 52
Second draw :
P(hearts 2) = 12 / 51
P(both cards being hearts) :
(13 /52) × (12/51) = 156 / 2652 = 26/442 = 13 / 221 = 0.0588235
2) What’s the probability that exactly one of the cards are hearts?
First draw being hearts, 2nd not hearts Or First draw not hearts and 2nd being hearts
P(first draw hearts) = 13 /52
P(2nd not hearts) = 39/51
13/52 × 39/51 = 0.1911764
P(first not hearts) = 39 /52
P(2nd being hearts) = 13 / 51
39/52 × 13/51 = 0.1911764
Hence, (0.1911764 + 0.1911764) = 0.3823529
3) What’s the probability that none of the cards are hearts
P(first draw, no hearts) = 39/52
P(second draw, no hearts) = 38/ 51
39/52 × 38/51 = 1482 / 2652 = 0.5588235

40 points David invests $10,000 in a savings account that pays 3.5% simple interest. If David makes no withdrawals or deposits to the account, how much will be in the account after 7 years? O $2,450 O $11,750 O $12,450 O Not Here
Answer:
FV= $12,450
Step-by-step explanation:
Giving the following information:
David invests $10,000 in a savings account that pays 3.5% simple interest.
To calculate the future value, we need to use the following formula.
FV= PV*(1+i*n)
n= 7
i= 0.035
PV= 10,000
FV= 10,000*(1+0.035*7)
FV= $12,450
Question 2 of 5
Type the correct answer in the box. Use numerals instead of words.
For this item, a non-Integer answer should be entered as a fraction using/as the fraction bar.
Simplify the numerical expression.
1 + 24 + ( + 3) = 1
The expression has a value equal to ???
Answer:
27
Step-by-step explanation:
Given expression :
1 + 24 + ( + 3) = 1
Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.
1 + 24 + ( + 3) - 1 = 0
Now, opening the bracket, we get
1 + 24 + 3 - 1 = 0
Negative 1 and positive 1 will get cancel
24 + 3 = 0
or 27
Therefore, the value of the numerical expression 1 + 24 + ( + 3) = 1 is 27.

unghiurile ∢AOB și ∢COD sunt unghiuri opuse la vârf, O ∈ AC, iar PO ⊥ BD, P∈ Int ∢AOD. Dacă ∢COP = 133°, aflați măsurile unghiurilor ∢AOB și ∢BOC.
Răspuns:
<AOB = 43 ° și <BOC = 137 °
Explicație pas cu pas:
Găsiți diagrama atașată pentru o mai bună explicație a întrebării.
Din diagramă, <COP = <DOP + <COD
Deoarece <DOP = 90 ° și <COP = 133 °, la înlocuire
133 ° = 90 ° + <COD
<COD = 133 ° -90 °
<COD = 43 °
Deoarece <COD = <AOB (unghiuri direcționate opuse), deci <AOB = 43 °
Pentru <BOC:
Suma unghiurilor pe DBO dreaptă este de 180 °.
<BOC + <COD = 180 °
Dat <COD = 43 °
<BOC + 43 = 180 °
<BOC = 180 ° -43 °
<BOC = 137 °
Prin urmare, <AOB = 43 ° și <BOC = 137 °
PLEASE HURRY WILL GIVE BRAINLIEST Kaylee is buying bagels for a family gathering. Each bagel costs $0.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is A(x) =0.75x .
So A(12) = 9, meaning 12 bagels will cost 9 dollars.
Step-by-step explanation:
Please give me THANKS and BRAINLIES
Have a good day
The relationship between the total cost and the number of bagels purchased will be;
⇒ y = $0.75x
Where, y is total cost and x is number of bagels purchased.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Kaylee is buying bagels for a family gathering.
And, Each bagel costs $0.75.
Now,
Let number of bagels purchased = x
Total cost to purchased bagels = y
So, We get;
The relationship between the total cost and the number of bagels purchased;
⇒ y = $0.75x
Thus, The relationship between the total cost and the number of bagels purchased is;
⇒ y = $0.75x
Where, y is total cost and x is number of bagels purchased.

Find the original price of a pair of shoes if the sale price is $84 after a 30% discount.
Answer:
Original price = $ 120Step-by-step explanation:
To find the original price given the new price and percentage discount we use the formula
[tex]original \: \: price = \frac{100}{(100 - x)} \times new \: \: price \\ [/tex]
where
x is the percentage discount
From the question
new price = $ 84
% discount = 30%
Substitute the values into the above formula and solve
That's
[tex]original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10[/tex]
We have the final answer as
Original price = $ 120Hope this helps you

11. Julie wants to go shopping for new clothes. She
has a budget of $100. She spends $45 on a new pair of
jeans and $11 on each new shirt.
The equation 100 = 45 + 11s represents s, the number
of shirts Julie bought.
Write in complete sentences the first 2 steps that Julie
would use to solve this equation.
Answer:
5
Step-by-step explanation:
1. subtract 45 from both sides 55 = 11s
2. Divide by 11 on both sides [tex]\frac{55}{11} =\frac{11s}{11}[/tex]
3. And now you have 5 = s

what does B equal ? please help me
Answer:
108
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal when the lines are parallel
A = B
6x+18 = x+93
Subtract x from each side
6x+18 -x = x+93-x
5x +18 = 93
Subtract 18 from each side
5x + 18-18 = 93-18
5x =75
Divide by 5
5x/5 = 75/5
x = 15
Angle B
x+93
15+93
108
Answer:
Solution given:
<A+<B=180°[ alternate exterior angle are equal]
6x+18=x+93
6x-x=93-18
5x= 75
x=15
now
<B=15+93=108°
