Answer: 33\frac{3}{4}\ pounds

Step-by-step explanation:

The weight of Ana's dog at the time of its birth= 5\frac{5}{8}\ pounds=\frac{45}{8}\ pounds

By age 4, the dog weighed 6 times as much.

Now, the weight of Ana’s dog at age 4 =6\times\frac{45}{8}=\frac{45\times3}{4}=\frac{135}{4}\ pounds

Since, \frac{135}{4}=33\frac{3}{4}

The weight of Ana’s dog at age 4 = 33\frac{3}{4}\ pounds

Kaya's family spends $105 to rent a boat for 7 days. The total cost, c, of the boat rental is proportional to the number of days
Elza [17]

Answer:

c=15d

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Let

c ----> the total cost of the boat rental

d ---> is the number of days, the family rents the boat

we know that

Kaya's family spends $105 to rent a boat for 7 days

so

For d=7 days, c=$105

Find the value of the constant of proportionality k

k=\frac{c}{d}

substitute the given values

k=\frac{105}{7}=\$15\ per\ day

therefore

The linear direct equation is equal to

c=15d

What is 7/2 divided by 49/4?
ruslelena [56]

Answer:

\frac{2}{7}

Step-by-step explanation:

\frac{7}{2} ÷ \frac{49}{4} needs to be flipped and multiplied.

It will become \frac{7}{2} · \frac{4}{49}.

Simplify the fractions by replacing 7 with 1 and 49 with 7, since 7 is 1/7 of 49. Then, turn the 2 into a 1 and the 4 into a 2, since 2 is half of 4.

You will be left with 1 · \frac{2}{7}, which equals \frac{2}{7}

Problem: How many cubic yards of concrete must be ordered to pour the section
timama [110]

Answer:

0.9 yd³

Step-by-step explanation:

Information given:

Length = 18 ft

Width = 1.5 ft

Height = 1 ft

What to find/do:

First, convert the measurement from feet to yards. (3 ft = 1 yard)

Length = 18 ft = 6 yd

Width = 1.5 ft = 0.5 yd

Height = 1 ft = 0.3 yd

Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards.

Formula for volume = L*W*H

Plug in the values into the formula

V = 6*0.5*0.3 = 0.9 yd³

0.9 cubic yard of concrete must be ordered to pour on the given section.

Area of the volume
