Joe wants to build a doll house for his daughter. He wants the doll house to look just like his house. His house is 29 feet wide and 32 feet tall at the highest point of the roof. If the dollhouse will be 2.5 feet wide, how many feet will its highest point be? (Round your answer to one decimal place.)

Answers

Answer:

3.5 feet

Step-by-step explanation:

The highest point of the dollhouse will be 2.76 feet.

What is proportion?

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

Given that,

The width of house = 29 feet.

And the height of the house = 32 feet.

Also, the width of dollhouse = 2.5 feet

Let the height of the doll is x feet.

To find the value of x,

Use proportion property,

29 / 32 = 2.5 / x

x = (32 × 2.5) / 29

x = 80 / 29

x = 2.758

the height of the doll is 2.76 feet.

A scuba diver descends farther down into the ocean from an initial depth of 12.8 feet below sea level. The scuba diver descends at a constant rate for 312 minutes and reaches a depth no more than 49.2 feet below sea level.

What is the maximum rate, r, that the scuba diver may descend?

r≤10.4

r≥13 7/9

r≤13 7/9

Answers

Answer:

[tex]r \geqslant 10.4[/tex]

The maximum rate at which the diver will descend will be 7 feet per hour.

What is the rate of change?

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

Initial depth of scuba diver = 12.8 feet

Let's say the rate of a scuba diver is "r".

Initial depth + depth cover with constant rate ≤ final depth

12.8 + (312/60)r ≤ 49.2

r ≤ 7

Thus, the maximum rate at which a diver can descend is 7 feet per hour.

Hence"The maximum rate at which the diver will descend will be 7 feet per hour".

Anita earns 40 points every time she shops at Brookshire's. She needs a total of 1,500 points to receive a free set of dishes. So far she has earned 300 points. How many more times will Anita need to shop at the grocery store to earn the points she needs to earn the dishes?
a. 1800
b. 30
c. 1200
d. 45

Answers

B,
1500 - 300 = 1200
1200/40 = 30
Answer:Anita will need to visit Brookshire 30 more times to receive a free set of dishes.Step-by-step explanation:

We know that:

1500 - 300 = required points to receive a free set of dishes1 day = 40 points.

Now, let's simplify.

=> 1500 - 300 = required points to receive a free set of dishes=> 1200 = required points to receive a free set of dishes=> 1 time = 40 points=> 1 time × 30 = 40 × 30                                                    [30 x 40 = 1200]=> 30 times = 1200 pointsConclusion:

Therefore, Anita will need to visit Brookshire 30 more times to receive a free set of dishes.

A rectangle has a perimeter of 270cm and its length is 2½cm times its width find its width​

Answers

Answer:

Step-by-step explanation:

If you mean length is 2½ times its width not "2½cm times its width"

      2(L + W) = 270

2(2.5W + W) = 270

      2(3.5W) = 270

              7W = 270

                W = 38.5714285714...

                W ≈ 38.57 cm

Answer:

Width = 38. 57 cm

Step-by-step explanation:

The perimeter of a Rectangle = 270 cm

Now,

Let's take x to be the width.

Length = 2½ = 5x/2

According to the formula,

The perimeter of a rectangle = 2 ( l + w )

270 = 2 ( 5x/2 + x )

270 = 5x + 2x

270 = 7x

x = 270/7

x = 38. 57 cm.

• The width of a rectangle is 38.57 cm

The Hayes family and the Rodrigues family use their sprinklers last summer. The water output rate for the Hayes family sprinkler was 15 L per hour. The water Output rate for the Rodriguez family speakers is 30 L per hour.Families used their sprinklers for a combined total of 75 hour result in a total water of output of 1725 L how long was a sprinkler used?

Answers

Answer:

Hayes family: 35 hoursRodrigues family: 40 hours

Step-by-step explanation:

Let x and y represent the usage hours by the Hayes and Rodrigues families, respectively. The problem statement gives us relations that can be used to write equations for volume of use and for total hours.

  15x +30y = 1725 . . . . . total liters of use

  x + y = 75 . . . . . . . . . total hours of use

The second equation lets us write an expression for y:

  y = 75 -x

This can be substituted into the first equation to give ...

  15x +30(75 -x) = 1725

  -15x + 2250 = 1725 . . . . . . simplify

  -15x = -525 . . . . . . . . . . . subtract 2250

  x = 35 . . . . . . . . . . . . . . divide by -15

  y = 75 -35 = 40

The Hayes family used their sprinklers for 35 hours; the Rodrigues family used theirs for 40 hours.

In Ms. Rivera’s desk, there are 14 yellow markers. There are 8 more pink markers than yellow markers, and 6 more blue than pink. How many markers does Mrs. Rivera have in her desk?

Answers

Answer:

64

Step-by-step explanation:

since ms. rivera has 8 more pink markers than yellow markers you would add 8 and get 22, so she has 22 pink markers and 14 yellow. for the blue markers it says she has 6 more blue markets than pink so you would add 6 to the 22 pink markers and get 28.

So ms. rivera has 14 yellow, 22 pink, 28 blue

add them all together and you get 64.

The total number of markers Mrs. Rivera have in her desk is 64.

Given that, Ms. Rivera’s desk, there are 14 yellow markers.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the total number of markers be x.

There are 8 more pink markers than yellow markers

So, number of pink markers = 14+8

= 22

There are 6 more blue markers than pink markers

So, number of blue markers = 22+6

= 28

Here, x= Number of yellow markers + Number of pink markers + Number of blue markers

= 14+22+28

= 64

Therefore, the total number of markers Mrs. Rivera have in her desk is 64.

c. f(1)=96 f(n)=12⋅f(n−1) n≥2
d. f(1)=96 f(n)=2⋅f(n−1) n≥2

I do not see that any of your options will work.

Step-by-step explanation:

a) and b) have a false first statement because f(1) = 96, not 12

c) would create the sequence 96, 1152, 13824

d.) would create the sequence 96, 192, 384. 768...

I believe the correct answer would be

f(1) = 96     f(n) = ½f(n-1)  n ≥ 2
