• How can the product of two whole numbers (e.g., 48
and 19) help us find the product of two decimals with
the same digits (e.g., 0.048 and 1.9)? Write your
explanation in the text box.
Let's say we already did the work and found the result of 48*19. That result is 912.
When it comes to multiplying 0.048 and 1.9, we're going to need to do two things to transform those numbers into 48 and 19.
Move the decimal point of 0.048 exactly three spaces to the right. This is the same as multiplying by 1000. So 1000*0.048 = 48
Move the decimal point of 1.9 exactly one space to the right. This is the same as multiplying by 10. So 10*1.9 = 19
Overall, we've multiplied by 1000*10 = 10,000. This means 48*19 = 912 is 10,000 times larger compared to the result of 0.048*1.9
To fix this, we need to divide by 10,000 to get 912/(10,000) = 0.0912
Dividing by 10,000 is the same as moving the decimal point to the left four spaces. Note how 10,000 = 10^4.
I recommend using your calculator to see that 0.048*1.9 = 0.0912 which matches with the previous result we got.

Help please explain pythagorean theorem
Answer:
In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1]
{\displaystyle a^{2}+b^{2}=c^{2},}a^{2}+b^{2}=c^{2},
where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. The theorem, whose history is the subject of much debate, is named for the Greek thinker Pythagoras, born around 570 BC.
The theorem has been proven numerous times by many different methods—possibly the most for any mathematical theorem. The proofs are diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years.
The theorem can be generalized in various ways: to higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and to objects that are not triangles at all but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps, and cartoons abound.-Wikipedia

A specific type of financial instrument pays 15% simple interest (based on the purchase value) and lasts for 1.5 years. The instrument can be bought at any price. An investor purchases the instrument for P0, and has calculated that the total value of the investment (i.e. P0 plus interest earned) will be $4,000 at maturity.
Answer:
Correct answers:
$3265$
For this, we can use the formula
A=P0(1+rt).
We know that A=$4,000,r=15%=0.15 and t=1.5, so we can rearrange the formula for A to give
P0=A1+rt,
and substituting the known quantities gives
P0=$4,0001+0.15×1.5=$4,0001.225=$3,265.30..,
which is $3,265 to the nearest dollar.

Alfonso has 435 stamps in his collection. He wants to collect at least
815 stamps. Write and solve an inequality to determine how many
more stamps Alfonso must collect to reach his goal. Let d represent the
number of stamps Alfonso must collect to reach his goal.
435 + d-815; d-380
435 + > 815;d > 380
435 + d 2815;d > 815
435 +0 2 815; d 2380
Answer:
Inequality: [tex]435 + d \geq 815[/tex]
Solution: [tex]d \geq 380[/tex]
Step-by-step explanation:
He has 435 stamps in his collections.
He will collect d stamps, and he wants to collect at least 815 stamps, that is, the sum of 435 and d has to be at least 815.
So the inequality is given by:
[tex]435 + d \geq 815[/tex]
And the answer is given by:
[tex]d \geq 815 - 435[/tex]
[tex]d \geq 380[/tex]
The random variable X has a uniform distribution with values between 16 and 24. What is the mean and standard deviation of X
Answer:
[tex]Mean = 20[/tex]
[tex]SD = 2.31[/tex]
Step-by-step explanation:
Given
[tex]a = 16[/tex]
[tex]b = 24[/tex]
Solving (a): The mean
The mean of a uniform distribution is:
[tex]Mean = \frac{1}{2}(a + b)[/tex]
This gives:
[tex]Mean = \frac{1}{2}(16 + 24)[/tex]
[tex]Mean = \frac{1}{2}(40)[/tex]
[tex]Mean = 20[/tex]
Solving (b): The standard deviation
The standard deviation is:
[tex]SD = \sqrt{\frac{(b - a)^2}{12}}[/tex]
This gives:
[tex]SD = \sqrt{\frac{(24 - 16)^2}{12}}[/tex]
[tex]SD = \sqrt{\frac{(8)^2}{12}}[/tex]
[tex]SD = \sqrt{\frac{64}{12}}[/tex]
[tex]SD = \sqrt{5.333}[/tex]
[tex]SD = 2.31[/tex]
Find the zeros of the function.
Enter the solutions from least to greatest.
f(x) = 5x^2 - 20
lesser x =
greater x =
Answer:
lesser x = -2
greater x = 2
Step-by-step explanation:
The values of a function f(x) are the values of x for which f(x) = 0.
In this question:
[tex]f(x) = 5x^2 - 20[/tex]
So, finding the zeros:
[tex]5x^2 - 20 = 0[/tex]
[tex]5x^2 = 20[/tex]
[tex]x^2 = \frac{20}{5}[/tex]
[tex]x^2 = 4[/tex]
[tex]x = \pm \sqrt{4}[/tex]
[tex]x = \pm 2[/tex]
So
lesser x = -2
greater x = 2
I don’t know the answer to this question, I need help the question is in the picture!
Answer:
it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)

Answer:
8.67 dollars per ft squared
Step-by-step explanation:
This is a fraction equal to
130 dollars ÷ 15 ft squared
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 15
130 dollars ÷ 15
15 ft squared ÷ 15
=
8.67 dollars
1 ft squared
=
8.67 dollars
ft squared
= 8.67 dollars per ft squared
Answer:
$8.67
Step-by-step explanation:
you have the the price for 15 square ft
and you are trying to get the price for 1 square ft
just divide the original price by 15
here's the equation format
130 = 15 x

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them.
The force is 0.006 Newtons when the distance between the objects is 4 metres.
Work out d (rounded to 2 DP) when F=0.045 Newtons.
Answer:
d = 1.46 m
Step-by-step explanation:
We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:
From the question given above,
F is inversely proportional to square of d. This can be written as:
F ∝ 1/d²
F = K/d²
Cross multiply
K = Fd²
But:
Force (F) = 0.006 N
Distance (d) = 4 m
Constant (K) =?
K = Fd²
K = 0.006 × 4²
K = 0.006 × 16
K = 0.096 Nm²
Therefore, the relationship between the force (F) and the distance (d) is:
F = K/d²
F = 0.096 / d²
Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:
Force (F) = 0.045 N
Constant (K) = 0.096 Nm²
Distance (d) =?
F = K/d²
0.045 = 0.096 / d²
Cross multiply
0.045 × d² = 0.096
Divide both side by 0.045
d² = 0.096 / 0.045
Take the square root of both side.
d = √(0.096 / 0.045)
d = 1.46 m.
