Matilda is filling a circular section of her porch with colorful pebbles. She knows the diameter of the circular section is 15ft, and each bag of pebbles covers 10ft. How many bags of pebbles will Matilda need? A. 15 bags B. 16 bags C. 17 bags D. 18 bags

Answers

Answer:

D. 18 bags

Step-by-step explanation:

Given:

Matilda is filling a circular section of her porch with colorful pebbles.

Diameter of circular section = 15 feet.

Each bag of pebbles covers 10 square feet.

Question asked:

How many bags of pebbles will Matilda need?

Solution:

Diameter of circular section = 15 feet

Radius, r = (Diameter)/(2)=(15)/(2)  =7.5\ feet

Area\ of\ circular\ section=\pi r^(2)

                                        =(22)/(7) *7.5*7.5=(1237.5)/(7)=176.78} \ square\ feet

10 square feet is covered by number of bag of pebbles = 1

1 square feet is covered by number of bag of pebbles = (1)/(10)

176.78 square feet is covered by number of bags of pebbles =  

(1)/(10)*176.78=17.67

We found up to 17 bags of pebbles there is still some place left to fill the section:-

Thus, Matilda need about 18 bags of pebbles to fill the  circular section of her porch.

a 14 foot ladder is leaning against a building the ladder makes a 45 degree angle how far up the building does the ladder reach

Answers

When the 14 foot ladder is leaning against a building, which is vertical as shown in the attached graph, with 45 degree angle. If we use the sin equation for this problem we can find out the answer. 

Sin 45 = X / 14
X = 14 * sin45
X = 9.9 foot
Therefore ladder will reach to 9.9 foot height in the building

The tree nearest to the classroom is 30 feet tall. In another 10 years it will grow 5 more feet. If the variable h stands for the height of the tree 10 years from now, which of the following choices is the most reasonable value for h?A.
10 feet

B.
3 feet

C.
50 feet

D.
35 feet

Answers

If you would like to know the height of the tree 10 years from now, you can calculate this using the following steps:

h ... the height of the tree 10 years from now
h = 30 feet + 5 feet = 35 feet

The correct result would be D. 35 feet.

Zoe bought 1.5 pounds of apples for $3.50 per pound. She wanted to find the total cost using partial products. Part A Drag all of the partial products into the box that Zoe needs to solve the problem. if you can answer this then you can get 17 points and brainless if you get it right

Answers

Answer:

The total cost for 1.5 pounds of apples is $5.25

Step-by-step explanation:

To find the total cost using partial products, you can do the following:

Calculate the cost for 1 pound of apples, which is $3.50.

Since Zoe bought 1.5 pounds of apples, you can use partial products to find the total cost:

First, calculate the cost for 1 pound: $3.50.

Next, calculate the cost for 0.5 pounds (half of 1 pound), which is half of $3.50: $3.50 / 2 = $1.75.

Finally, add the cost for 1 pound and 0.5 pounds to find the total price: $3.50 + $1.75 = $5.25.

So, the total cost for 1.5 pounds of apples is $5.25.

The value of X and Y vary directly, and when X= 4 Y equals -10. Find the value of Y when X equals 10.

Answers

y = - 25

since x varies directly with y then we can express the relationship as

x = ky ← k is the constant of variation

to find k use the given condition y = - 10 when x = 4

k = (x)/(y) = (4)/(-10) = - (2)/(5)

hence x = - (2)/(5) y

when x = 10

10 = - (2)/(5) y

multiply both sides by - 5 and divide both sides by 2 )

- 50 =  2y ⇒ y = - 25
