Answer:
x = 11
The value "11" makes the equation true.
2 ( x - 5 ) = 12
2 ( 11 - 5 ) = 12
2 ( 6 ) = 12
12 = 12

Find the volume of a pyramid with a square base, where the side length of the base is 4.8\text{ cm}4.8 cm and the height of the pyramid is 4.6\text{ cm}4.6 cm
Answer: 35.328 cubic inches.
Step-by-step explanation:
Volume of square pyramid = [tex]\dfrac{a^2}{3}h[/tex] , where a = length of base , h = height
Given: For a square pyramid
a= 4.8 cm and h = 4.6
Then, Volume = [tex]\dfrac{4.8^2}{3}\times4.6[/tex]
[tex]=\dfrac{23.04}{3}\times4.6\\\\=35.328\text{ cubic cm}[/tex]
Hence, the volume of a pyramid with a square base = 35.328 cubic inches.

Step-by-step explanation:
1) Triangle T1 is transformed into triangle T2 by
a. dilation with scale factor of 1/2
b. reflection over the y-axis
c. translation
2) and triangle T2 is transformed into trinagle T3 by
a. dilation with scale factor 1/2
b. reflection over the x-adis
c. rotation
Answer:
1) The correct option is;
b. Reflection over the y-axis
2) The correct option is;
a. Dilation by a scale factor of 1/2
Step-by-step explanation:
1) The rule for reflection over the y-axis is given as follows;
Given the point of the preimage before the reflection = (x, y), the point of the image after the reflection will be (-x, y)
The coordinate of a point on T1 is (-2, 4). The coordinate of similar point in T2 is (2, 4) which satisfies the rule for reflection over the y-axis
2) The length of a side in triangle T2 is given by the formula for finding the length, l, of segments between coordinate points as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Point 1, (x₁, y₁) = (2, 4)
Point 2, (x₂, y₂) = (6, 2)
The length = √((2 - 4)² + (6 - 2)²) = 2·√5
The length of the corresponding side in T3 is given as follows;
Point 1, (x₁, y₁) = (1, 2)
Point 2, (x₂, y₂) = (3, 1)
The length = √((1 - 2)² + (3 - 1)²) = √5
The length of of a side T3 = 1/2 of the length of a side of T2
Therefore. triangle T2 is transformed into triangle T3 by dilation with a scale factor of 1/2.

If water flows through a pipe at a rate of 6 milliliters per hour, how wil I express this rate of flow in pints per day?
Answer:
0.304 pints per day
Step-by-step explanation:
Here, we want convert
if 6 milliliters flow in an hour , then in a day which is 24 hours, the amount that will flow is 24 * 6 = 144 milliliters in a day
so we need to convert this to pint
mathematically;
1 pints= 473.176 ml
x pints = 144 ml
x =
144/473.16 = 0.304 pints per day
Write an equation in slope-intercept form of the line that passes through (3,8) and (1,-2)
Step-by-step explanation:
let eqn be y = mx + b.
m = (-2 - 8)/(1 - 3) = 5
sub (3, 8):
8 = 5(3) + b
b = -7

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!

The radius of the moon is approximately 1,350,000 m. What is the radius in kilometers? (1 km=1000m)
Answer:
I believe it is 1,350 but i am not completely sure
Step-by-step explanation:
The radius of the moon in Kilometers is 1350 km.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.
Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,
1 km = 1000m
1 m = 1 / 1000 km
1350000 meters = 1350000 / 1000 km
1350000 meters = 1350 km
