Rectangle A is similar to rectangle B. The ratio of the length of rectangle A to the length
of rectangle B is 2 : 5. The width of rectangle BIs 36 inches. What is the width of
rectangle A?
A 90 in.
B
17.6 in.
B
А
с
28.8 in.
D
14.4 in.
Answer:
D. 14.4
Step-by-step explanation:
In similar polygons, corresponding sides are proportional. We can write the proportion:
[tex]\frac{l-A}{l-B} =\frac{w-A}{w-B}[/tex]
l-A is the length of A, l-B is the length of B, w-A is the width of A, and w-B is the width of B. We are given the ratio of the lengths is 2:5, so we can substitute it in:
[tex]\frac{2}{5} =\frac{w-A}{36}[/tex]
We can cross multiply:
72 = 5w-A
w-A = 14.4
Unit: Inference comparing two groups or populations Unit test Owen lives in New York City and his brother Karson lives in Boston. They both complained about the high prices of avocado in their neighborhoods, so they decided to test whether there's a difference in the average price of avocado. Each of them took a random sample of shops in their neighborhoods and got the price of avocado from each shop. Then, they calculated the average price in each group. Assume that all conditions for inference have been met. Which of these is the most appropriate test and alternative hypothesis?

At Corner Deli, you can get 6 bagels for $6. How much does it cost per 1 bagel?
(Find the unit rate)
If you can, please explain.
Answer:
$1.00 per bagel
Step-by-step explanation:
To find the unit rate, you just have to divide the number of bagels by how much they cost.
In your problem, the number of bagels is 6 and the price is also 6.
Now all you have to do is divide 6 by 6 and the answer to that is 1.
Example: 6 ÷ 6 = 1
Which equation represents a line wit a slope of 5/2 and a y-intercept of -8/3?
Answer:
Y=5/2x + -8/3
Step-by-step explanation:
Y=Mx + b where m is the slope and b is the y intercept.
y=5/2 + -8/3
Hence, the equation of line is [tex]y=\frac{5}{2}x-\frac{-8}{3}[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given that,
The slope of [tex]\frac{5}{2}[/tex] and a y-intercept of [tex]-\frac{8}{3}[/tex].
As we know the slope of line is
[tex]y=mx + b[/tex]
where [tex]m[/tex] is the slope and [tex]b[/tex] is the [tex]y[/tex] intercept.
So,
[tex]m=\frac{5}{2},b=-\frac{8}{3}[/tex]
[tex]y=\frac{5}{2}x -\frac{8}{3}[/tex]
Hence, the equation of line is [tex]y=\frac{5}{2}x-\frac{-8}{3}[/tex].

Answer:
The correct answer is B. m = 1.1
Step-by-step explanation:
Every time x is increases by 1, y increases by 1.1.
Answer:
m = 1.1
Step-by-step explanation:
The function equation is y = 1.1x because every increase in x produces an additional output of 1.1, therefore the slope equals 1.1.

Show me how to find x using the correct equation shown here (geometry)
Answer:
x = 13
Step-by-step explanation:
The 2 angles same- side interior angles and sum to 180°
Then the equation to use to find x is
12x - 29 + 4x + 1 = 180
16x - 28 = 180 ( add 28 to both sides )
16x = 208 ( divide both sides by 16 )
x = 13
Answer:
13
Step-by-step explanation:
Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.
Sum of co - interior angles are supplementary.
12x - 29 + 4x + 1 = 180
12x + 4x - 29 + 1 = 180
16x - 28 = 180
16x = 180 + 28
16x = 208
x = 208 / 16
x = 13

Answer:
y = [tex]\frac{24}{x}[/tex]
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 4 when x = 6 , then
4 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
24 = k
y = [tex]\frac{24}{x}[/tex] ← equation of variation

==============================================
Explanation:
Place the decimal point between the first two nonzero digits. So we'll place the decimal point between the 3 and 2 to get 3.245
Now ask yourself "how many spots to the right must I move the decimal point to get back to 324.5?" The answer is "2 spots to the right"
That "2" from "2 spots to the right" is the exponent over the 10.
So that's how we get to the answer 3.245 * 10^2
Using your calculator, you should find that 3.245 * 10^2 = 324.5
--------------
Side note: if the exponent over the 10 is negative, then the decimal point will move left that number of spaces.
For example, 3.2 * 10^(-2) = 0.032 showing it has moved 2 spaces to the left.

9 x 3.14 = 28.26(area of circle)
Now we multiply by height
28.26 x 5 = 141.3
Now we divide by 3 since its part for the formula of finding the cone's volume:
141.3 x 1/3(basically just dividing by 3) = 47.1
Now let's find the volume of the cylinder:
3^3 = 9, 9 x 3.14 = 28.26
28.26 x 14 = 395.64
Now let's add the given volumes:
395.64 + 47.1 = 442.74 cm^3 is your answer.

Simone used 2 1/3 kilograms of flour to bake a cake . She used 4/5 kilograms of flour more to bake a second cake. How much flour did she use to bake the second cake?
Answer:
3.13 kilograms used for the second cake
Step-by-step explanation:
because the fractions have different denominators you have to multiply the denominators together to figure out what to change them too. but instead you can just figure out what the decimal for each is. 1/3 is 0.33, and 4/5 is 0.80. all you do is add these together to get 1.13. so now all you do is add 2+1.13 to get 3.13.

Find the y=a(b)^x form for the exponential function passing through points (1,48) and (3,12)
Answer:
y = 96 * (1/2)ˣ or
y = (-96)*(-1/2)ˣ
Step-by-step explanation:
y=a(b)ˣ
pass (1 , 48): 48 = a * b¹ ab = 48 ...(1)
pass (3 , 12): 12 = a * b³ ab³ = 12 ...(2)
(2)/(1): ab³/ab = b² = 12/48 = 1/4
b = 1/2 or b = - 1/2

There was a population of 160 bears in a National Park. After a year, the population increased by 15%.
How many bears are there in the park now?
Answer:
184
Step-by-step explanation:
Increased by 15%: there are 15%, or 0.15 more bears.
To solve, we need to add the number of bears last year, and the number of new bears in the park.
1 * 160 + 0.15 * 160 =
1.15 * 160 =
184 bears
