If twelve inches correspond to 30.48 centimeters, how many centimeters are there in thirty inches?
Answer:
76.2 cm
Step-by-step explanation:
Do 30.48 / 12 to find the amount of centimeters per inch. 30.48 / 12 = 2.54
So, for ever inch, there are 2.54 cm. Now to find the amount of centimeters in thirty inches, do 2.54 x 30 = 76.2.

Answer:
Step-by-step explanation:
You are given the equation g(x)=5x-2. You simply take the values given and put those values into the equation.
g(-4)=5(-4)-2=-20-2=-22
g(-7)=5(-7)-2=-35-2=-37
g(0)=5(0)-2=-2
g(23)=5(23)-2=115-2=113
g(38)=5(38)-2=190-2=188

Answer:
x = 6.6, y = -6.8
Step-by-step explanation:
Subtract 3 x from both sides of the equation.
y = 13 - 3x
4x + 3y = 6
Replace all occurrences of y with 13 − 3 x in each equation.
-5x + 39 = 6
y = 13 - 3x
Solve for x in the first equation.
x = [tex]\frac{33}{5}[/tex] or 6.6
Replace all occurrences of x with 6.6 in each equation.
y = [tex]-\frac{34}{5}[/tex] or - 6.8

a man has 290 ft of fencing to build the pen shown in the illustration. If one in is a square, find the outside dimensions.
the dimensions are feet(smaller value) by feet (larger value)
9514 1404 393
Answer:
40 ft by 85 ft
Step-by-step explanation:
The total length of the three "vertical" partitions is ...
3x = vertical partitions
The total length of the horizontal sides is ...
2(x +(x +5)) = 4x +10
Then the perimeter is ...
P = vertical partitions + horizontal sides
290 = 3x +4x +10
280 = 7x
x = 40
2x+5 = 85
The overall dimensions are 40 ft by 85 ft.
Use 3.14 for Pi. *Answer choices may be rounded.* 5 points 1. 15 cm 7.5 cm 176.6 706.5 1324.7 5298.8
Answer:
C. 1324.7 cm³
Step-by-step explanation:
Volume of cylinder = πr²h
π = 3.14
radius (r) = ½ of 15 = 7.5 cm
Height (h) = 7.5 cm
Plug in the values
Volume = 3.14*7.5²*7.5 = 1324.7 cm³

The time, t, for am ice cube to melt. is inversely proportional to the temperature, T, of the water the ice cube is placed. If it takes an ice cube 2 minutes to melt in 75f water, how long will it take an ice cube of the same size to melt in 80f water?
Answer:
15/8 minutes
Step-by-step explanation:
The inverse relationship implies the following equation.
[tex]t=\frac{k}{T}[/tex]
where k is a constant.
You are given a t and T that go together, so
[tex]2=\frac{k}{75}[/tex]
This implies that k=150. Now you know that the relationship is
[tex]t=\frac{150}{T}[/tex]
Now substitute 80 for T to get the answer.
[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]
minutes.
It takes an ice cube of the same size to melt in 80f water 15/8 minutes.
We have given,
The time t for am ice cube to melt. is inversely proportional to the
temperature T of the water in the ice cube is placed.
What is the inverse relationship?The inverse relationship implies the following equation.

A 10-gal aquarium is 4 in. higher than it is wide. Its length is 17 in., and its volume is 4284 in.^3. What are the height and width of the aquarium?
Answer:
[tex]W = 18[/tex] -- Width
[tex]H = 14[/tex] --- Height
Step-by-step explanation:
Given
[tex]V = 4284[/tex] -- Volume
[tex]L = 17[/tex] -- Length
[tex]H = ??[/tex] -- Height
[tex]W = 4 + H[/tex] -- Width
Required:
Find the height and the width
Volume is calculated as:
[tex]V = LWH[/tex]
This gives:
[tex]4284 = 17 * (4+H) * H[/tex]
[tex]4284 = 17 * (4H+H^2)[/tex]
Open bracket
[tex]4284 = 17 * 4H+17*H^2[/tex]
[tex]4284 = 68H+17H^2[/tex]
Divide through by 17
[tex]252 = 4H+H^2[/tex]
Write as a quadratic expression
[tex]H^2 + 4H - 252 = 0[/tex]
Expand
[tex]H^2 + 18H - 14H - 252 = 0[/tex]
Factorize:
[tex]H(H + 18) - 14(H + 18) = 0[/tex]
Factor out H + 18
[tex](H - 14)(H + 18) = 0[/tex]
[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]
[tex]H = 14[/tex] or [tex]H = -18[/tex]
But Height can not be negative. So:
[tex]H = 14[/tex]
Recall that:
[tex]W = 4 + H[/tex]
[tex]W = 4 + 14[/tex]
[tex]W = 18[/tex]

The appropriate rephrase statement to proof the Pythagorean theorem is
In ΔABC , if ∠B = 90°, then AB² + BC² = AC²
Pythagoras's theorem is used to calculate the sides of a right angle triangle. The formula is represented as follows
c² = a² + b²where
c = hypotenuse
a and b are either adjacent or opposite sides of the triangle.
A right angle triangle is a triangle that has one angle as 90°. Therefore, from the triangle below, the appropriate rephrase statement to proof Pythagoras theorem is as follows:

3x + 2(4x - 4) = 3
Anyone know the answer?
Answer:
x=1
Step-by-step explanation:
3x+2(4x-4) = 3
3x+8x-8 = 3
11x-8 = 3
11x = 11
x = 11/11 = 1
The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1
The given expression is,
⇒ 3x + 2 (4x- 4) = 3
We can simplify by apply distributive property and combine like term,
⇒ 3x + 2 (4x- 4) = 3
Apply distributive property,
⇒ 3x + 8x - 8 = 3
Combine like term,
⇒ 11x - 8 = 3
Add 8 both side,
⇒ 11x = 3 + 8
⇒ 11x = 11
Divide by 11,
⇒ x = 11 / 11
⇒ x = 1
Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1
