Answer:
7.2inches.
Step-by-step explanation:
Given parameters:
Radius of Circle A = 6inches
Unknown:
Radius of circle B = ?
Solution:
We are to find the radius of circle B.
The relationship between circle A and B is such that;
Radius of Circle B = 20% greater than that of A
Radius of Circle B = 1.2 x 6 = 7.2inches.

Of two consecutive integers, twice the smaller is four less than the greater. Find the integers. Provide and equation if you don't have a direct answer.
Answer:
The smaller integer is -3 and the greater integer is -2
Step-by-step explanation:
Equations
Let's call
x = the smaller integer
x + 1 = greater consecutive integer
The relationship between them is that twice the smaller is four less than the greater:
2x = x + 1 - 4
Subtracting x:
x = 1 - 4
Operating:
x = -3
x + 1 = -2
The smaller integer is -3 and the greater integer is -2
The length, width, and height of a rectangular prism can be represented by the expression (x + 3), (x + 7) and (x - 1). write an expression to represent the surface area of the prism
Answer:
A=2wl+2lh+2hw
A=2(x+7)(x+3)+2(x+3)(x-1)+2(x-1)(x+7)
A=2(x^2+7x+3x+21)+2(x^2-x+3x-3)+2(x^2+7x-x-7)
A=2(x^2+10x+21)+2(x^2-2x-3)+2(x^2+6x-7)
Answer:
6x²+36x+22
Step-by-step explanation:
Surface Area = 2(wl + hl + wh)
Length = (x+3)
Width = (x+7)
Height = (x-1)
Surface Area = 2((x+7)(x+3) + (x-1)(x+3) + (x+7)(x-1))
Then simplify
2((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))
=(2)((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))
=(2)((x+7)(x+3))+(2)((x−1)(x+3))+(2)((x+7)(x−1))
=2x²+20x+42+2x²+4x−6+2x²+12x−14
=6x²+36x+22

Step-by-step explanation:
which of the following relations or graphs are functions
Answer:
Step-by-step explanation:
The functions are:
(a), (c), (d), (e).
Relations may or may not represent a function.
The relations that are functions are (a), (c), (d), (e)
Graph (a) shows a linear relationship, and all linear relations are functions.
Graph (b) fails the vertical line test, because an x value corresponds to multiple y values; so graph (b) is not a function.
Similarly, ordered pair (f) is not a function because an x value corresponds to multiple y values
Other relations (c), (d) and (e) are functions

A line passes through (-1, 3) and (p, 7) and has a slope of -4/3 Find the value of p.
slope= (x2-xl)(y2-y1)
Answer:
Step-by-step explanation:
y - 3 = - [tex]\frac{4}{3}[/tex] ( x + 1 )
y = - [tex]\frac{4}{3}[/tex] x - [tex]\frac{4}{3}[/tex] + 3
y = - [tex]\frac{4}{3}[/tex] x + [tex]\frac{5}{3}[/tex]
7 = - [tex]\frac{4}{3}[/tex] p + [tex]\frac{5}{3}[/tex]
[tex]\frac{4}{3}[/tex] p = - 7 + [tex]\frac{5}{3}[/tex]
p = ( - [tex]\frac{16}{3}[/tex] ) × [tex]\frac{3}{4}[/tex] = - 4

Find the value of b. Then find the angle measures of the pentagon.
Answer:
b = 90
Step-by-step explanation:
Sum the interior angles of the pentagon and equate to 540
Starting from the top and going clockwise
b + b + 45 + 90 + 2b - 90 + [tex]\frac{3}{2}[/tex] b = 540 ← simplify left side
[tex]\frac{11}{2}[/tex] b + 45 = 540 ( multiply through by 2 to clear the fraction )
11b + 90 = 1080 ( subtract 90 from both sides )
11b = 990 ( divide both sides by 11 )
b = 90
Thus
b + 45 = 90 + 45 = 135
2b - 90 = 2(90) - 90 = 180 - 90 = 90
[tex]\frac{3}{2}[/tex] b = [tex]\frac{3}{2}[/tex] × 90 = 135
The angle measure from the top clockwise are
90°, 135°, 90°, 90°, 135°

what’s the answer??
Answer: The answer is x=0
Step-by-step explanation:
Rewrite the equation as a trinomial.
x 2 + 12 x + 0
Move 0 to the right-hand side.
x 2 + 12 x = 0
Divide the coefficient of the x
-term by 2, then square the result. Add the result to both sides.
12 /2 = 6 ;6^2 = 36
x 2 + 12 x + 36 = 36
Factor the perfect square trinomial
x 2 + 12 x + 36
on the left-hand side.
( x + 6 ) 2 = 36
Take the square root of both sides and solve for x .
√ ( x + 6 )^ 2 = ± √ 36 =
x+ 6 = ± 6
x = − 6 + 6 = 0
x = − 6 − 6 = − 12
Check
If x = 0 :
( 0 ) ^2 + 12 ( 0 ) = 0
0 = 0
If x = − 12 :
( − 12 ) ^2 + 12 ( − 12 ) = 0
144 − 144 = 0
0 = 0

What two integers between -100 and -20 could be divided to equal a number close to 0?
how does the percent equation relate to proportional quantities?
Answer:
Step-by-step explanation:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Answer:
The proportion is a general case of percentage.
Step-by-step explanation:
Proportion is a general case of percentage.
It describes how much of the total a particular sample is.
For example, if a pie contains eight slices and you have five, the proportion is 5/8.
You have a total of five out of eight.
A percent (the number of parts out of 100) is a special case of proportion where the denominator (“whole”) equals 100 parts.
I suspect that percentages were created to allow a normalized comparison of proportions when the total number of parts was not the same.
Imagine a small pizza with 6 slices and a large pizza with 8 slices.
If Tom got 4 from the first and Ram got 5 from the second, it is not immediately clear who got more from the second.
Converting 4/6 and 5/8 to percentages (66.7 and 62.5) allows you to see when the denominator equals who got relatively "more".
Furthermore, I suspect that 100 was used because we live in a 10-base world (we have 10 fingers, which makes it natural).

A painting is made from three different colors whose ratios are as follows: 4 parts blue, 3 parts red, and 3 parts green. The blue part of the painting took 12 gallons of paint. How many gallons of paint were needed for the green part of the painting
Answer: 9 gallons
Step-by-step explanation:
Given: Ratio of colors in painting:
4 parts blue, 3 parts red, and 3 parts green.
Total parts = 4+3+3 =10
Fraction of blue = [tex]\dfrac{\text{Number of parts of blue}}{\text{total parts}}=\dfrac{4}{10}[/tex]
Since, Quantity of blue color used = 12 gallons
Let total quantity of color be x,
[tex]\dfrac{4}{10}x=12\\\\\Rightarrow\ x=\dfrac{120}{4}=30\text{ gallons}[/tex]
Total color used = 30 gallons
Color used for green part only = [tex]\dfrac{3}{10}\times30 = \text{9 gallons}[/tex]
Hence, 9 gallons of paint were needed for the green part of the painting.

4x + (-3) = 5x + 3?????
Hi there! :)
[tex]\large\boxed{x = -6}[/tex]
Solve for x:
4x + (-3) = 5x + 3
Adding a negative number is simply subtracting, therefore:
4x - 3 = 5x + 3
Subtract 4x from both sides:
4x - 4x - 3 = 5x - 4x + 3
-3 = x + 3
Subtract 3 from both sides:
-3 - 3 = x + 3 - 3
-6 = x
Answer:
[tex]x=-6[/tex]
Step-by-step explanation:
Isolate the variable.
[tex]4x+(-3)=5x+3[/tex]
[tex]4x=5x+6[/tex]
[tex]0=x+6[/tex]

Find the perimeter of the given figure, round to the nearest tenth
Answer:
2√424 + 62 ≈ 103.1825205639 ≈ 103.2 units
Explanation:
Given the two baselengths, and the perpendicular height of the trapezoid, you can actually find the perimeter through the pythangorean theorem because the perpendicular height or height that forms a right or 90 degree angle makes a right triangle(2 be exact because this is an isoceles trapezoid which has two adjacent right triangles).
This is true of the trapezoid is icosceles.
Answer:
You cannot find the perimeter with numbers given.
Step-by-step explanation:
The top length, base length, and height are not sufficient to determine the perimeter of a trapezoid
