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!

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.

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

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.

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.

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

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
