Answer:
The length will be 14.25 cm and the width will be 17.1 cm
Step-by-step explanation:
Length = 1.9 * 7.5 cm = 14.25 cm

Complete the ratio table. 2 3 10 15 12 18 57 60
answer:
38 and 40
explanation:
i hope i read your question correctly but basically x is 2/3 of y. for example 2 is 2/3 of 3, and 10 is 2/3 of 15, so 38 is 2/3 of 57 and 40 is 2/3 of 60.
Part A: Estimate and interpret the correlation coefficient. (5 points) Part B: Create an outlier point for this graph that would cause the correlation to increase. Explain your reasoning. (5 points)
Answer:
The correlation coefficient will be "0.9188". The further explanation is given below.
Step-by-step explanation:
Let the values,
x = Age
y = Length
(A)...
[tex]Cor(x,y)=\frac{\Sigma (xi-\bar{x})(yi-\bar{y})}\sqrt{\Sigma(xi-\bar{x})^2}\Sigma(yi-\bar{y}))^2}[/tex]
⇒ [tex]=0.9188[/tex]
The age as well as the length of the legs seem to be highly positive.
(B)...
Now even the the paint (4.5, 8) appears to have been extreme rarity, because it's such a considerable distance from either the long term trend. Once we remove this obsⁿ, the maximum correlation becomes 0.9414. Thus, the addition of paint will reduce the association.

A church steeple is 30 feet tall with square cross sections. The square at the base has side 3 feet, the square at the top has side 6 inches and the side varies linearly in between. Compute the volume.
Answer:
Volume= 540 ft^3
Step-by-step explanation:
Since volume= length times Width times height, you do 3 times 6 times 30= 540 ft^cubed.
The church steeple is a frustum, and the volume of the church steeple is 107.5 ft³
How to determine the volume of the steeple?The given parameters are:
Height, h = 30 feetBase length, L = 3 feetTop length, l = 6 inchesCalculate the base area:
A₁ = L²
This gives
A₁ = (3 ft)²
A₁ = 9 ft²
Calculate the top area:
A₂ = l²
This gives
A₂ = (6 in)²
Express inches as feet
A₂ = (6/12 ft)²
A₂ = (0.5 ft)²
Evaluate the square
A₂ = 0.25 ft²
The volume of the church steeple is then calculated using:
[tex]V = \frac h3 * (A_1 + A_2 + \sqrt{A_1 * A_2})[/tex]
This gives
[tex]V = \frac {30}3 * (9 + 0.25 + \sqrt{9 * 0.25})[/tex]
Evaluate the product, the sum and the quotient
[tex]V = 10 * (9.25 + \sqrt{2.25})[/tex]
Evaluate the exponent
[tex]V = 10 * (9.25 + 1.5)[/tex]
Evaluate the product
V = 107.5
Hence, the volume of the church steeple is 107.5 ft³

What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The function is,
⇒ g (x) = 2x + 3
And, The value of x = - 3
Now,
Since, The function is,
⇒ g (x) = 2x + 3
Hence, Put x = - 3, we get;
⇒ g (x) = 2x + 3
⇒ g (- 3) = 2 × - 3 + 3
⇒ g (-3) = - 6 + 3
⇒ g (-3) = - 3
Thus, The value of g (-3) will be;
⇒ g (-3) = - 3

Given the figure below, find the value of x and z.
Answer:
X=12 and z=109
Step-by-step explanation:
z has the same degree measure as the Angle across from it of 109 degrees.
to solve for x we first have to subtract 109 from 180 since it’s a straight angle to get 71. then we solve for the equation 8x-25 = 71, adding 25 to both sides, 8x=96, dividing 8 by both sides, to get x=12
Answer:
z = 109 x = 12
Step-by-step explanation:
Well z is is very simple it is 109 because 109 and a are opposite from each other so they are the same.
But to find x some math is needed.
We know that 109 and (8x-25) are summplementary angles meaning they add up to 180.
So we can set up the following equation [tex]109+(8x-25)=108[/tex]
So we have to combine like terms meaning adding -25 and 109 which is 84.
And we also have to put the whole numbers on one side so we so 180-84 which is 96.
Now our equation looks like this -> [tex]8x=96[/tex].
And to get x by itself we do 96÷8 which is 12.
So x is 12.
The set of numbers 1, 3, 7, 11, 15, and 36 contains all possible values for q. What value of q makes the following equation true: 4q+9=37 ?
Answer:
q = 7
Step-by-step explanation:
4q + 9 = 37
If a letter and a number are together it means multiply.
Substitute 7 into the equation:
4(7) + 9 = 37
28 + 9 = 37
So q must equal 7

Answer:
You need to try and find the total cost of the food and drink and subtract it from the amount of money Simon pays.
Two cups of coffee costs 2.78 so -
2.78 + 2.78 = 5.56
One piece of cake costs 2.85 so the total amount is
5.56 + 2.85 = 8.41
Now we know the total, we can subtract it from the money given.
10 - 8.41 = 1.59
Simon will get 1.59 in change.
Answer:
£1.59
Step-by-step explanation:
2 cups of coffee cost:
=> 2(2.78)
=> £5.56
A piece of cake costs:
=> £2.85
Total Cost:
=> £5.56+£2.85
=> £8.41
Change he gets:
=> £10-£8.41

Will mark brainliest solve for x 32^(x +4) = 64^(2x–1)
Answer:
26/7 =x
Step-by-step explanation:
32^(x +4) = 64^(2x–1)
Rewrite each as a power of 2
32 = 2^5 and 64 = 2^6
2^5^(x +4) = 2^6^(2x–1)
We know a^b^c = a^(b*c)
2^(5*(x +4)) = 2^(6*(2x–1))
The bases are the same so the exponents are the same
5*(x +4) = 6*(2x–1)
Distribute
5x +20 = 12x -6
Subtract 5x
20 = 7x -6
Add 6 to each side
26 = 7x
Divide by 7
26/7 =x
