Answer:

The probability it will land on the black all three times out of three spins is 1/8.

What is Probability?Probability helps us to know the chances of an event occurring.

Given the probability of the spinner landing on black is 1/2. Therefore, the probability it will land on the black all three times out of three spins is,

Probability = (1/2) × (1/2) × (1/2) = 1/8

Hence, the probability it will land on the black all three times out of three spins is 1/8.

Is 75/100 equal to 3/4

Yes it is equal

75/100=15/20=3/4

75/100=15/20=3/4

Yes, 75/100 is equal to 3/4 because 75 is the third quart of 100 and 3/4 represents three quarts of an amount of something

The perimeter of the rectangle when x = 3 is 22. Which equation can be used to represent the perimeter of the rectangle, P(x)? P(x) = 2(f ∙ g)(x)

P(x) = (f ∙ g)(x)

P(x) = 2(f + g)(x)

P(x) = (f + g)(x)

Answer:

P(x) = 2(f+g)(x)

Step-by-step explanation:

perimeter of the rectangle = 2( length + width )

David ate 80 blueberries in 1 hour. How many did he eat in fifteen minuets? Fill in the double number lines to show your thinking.

Answer: He ate 20 blueberries in 15 minutes.

Step-by-step explanation: Okay so if you want to find out how you have to use fractions! 15 minutes is 1/4 of an hour. You multiple 1/4 by the amount of berries which is 80. When multiplied it is 20! I hope this helps. :)

I think garden center grass seed sells for eight dollars per pound Haley spent $10 on grass seeds what amount of C did he buy

If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.

10 = 8x. Divide both sides by 8

10/ 8 = x Simplify the fraction

1 1/4 = x

So, she bought 1 1/4 pounds of seeds

10 = 8x. Divide both sides by 8

10/ 8 = x Simplify the fraction

1 1/4 = x

So, she bought 1 1/4 pounds of seeds

The ratio of the perimeters of two similar triangles is 4:7. What is the area of each of these triangles if the sum of their areas is 65cm2.

Answer:

Part a) The area of the smaller triangle is

Part b) The area of the larger triangle is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

step 1

Find the scale factor

Let

z-----> the scale factor

------> ratio of corresponding perimeters

step 2

Find the area of each triangle

Let

z-----> the scale factor

x-----> the area of the smaller triangle

y-----> the area of the larger triangle

we know that

------> equation A

we have

substitute

------> equation B

substitute equation B in equation A and solve for y

Find the value of x

------>

and are the areas of two similar triangles.

Further explanation:

Explanation:

Let us assume that area of triangle 1 as A and the area of triangle 2 as B.

The given ratio of the perimeter of the two triangles is 4:7.

If two triangles are similar to each other than the ratio of areas of triangle is equal to the ratio of the square of perimeter.

The sum of areas of triangle can be expressed as follows,

The ratio of the areas of the triangles can be calculated as,

The value of A is

The area of second triangle is

The area of first triangle with area A can be calculated as follows,

and are the areas of two similar triangles.
