Answer:

1290.67 Yards/min

Step-by-step explanation:

We are given us a dimension in mile per hours. We are asked to convert it into yards per minutes unit.

Hence first we should convert mile inti yards and hour into minutes

1 mile = 1760 yards

44 mile = 1760 x 44 yards

= 7744 yards

1 hour = 60 minutes

Hence

44 mi/h = $\frac{7744}{60}$

= 1290.67

Hence 44 mi/h = 1290.67 yards/min

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box cos

RideAnS [48]

Answer:

Jillian sold 15 ten-oz bags and 9 sixteen-oz bags.

Step-by-step explanation:

Let x represent number of 10-oz bags and y represent number of 16-oz bags.

We have been given that Jillian sold 24 boxes of cookies in total. We can represent this information in an equation as:

$x+y=24...(1)$

We are also told that 10 oz. box costs $3.50, while the 16 oz. box costs $5.00, so the cost of x 10-oz bags would be $3.50x$ and cost of y 16-oz bags would be $5y$ .

At the end of one week, she collected $97.50. We can represent this information in an equation as:

$3.5x+5y=97.50...(2)$

Now, we will use substitution method to solve our system of equations. From equation (1), we will get:

$y=24-x$

Substitute this value in equation (2):

$3.5x+5(24-x)=97.50$

$3.5x+120-5x=97.50$

$-1.5x+120=97.50$

$-1.5x+120-120=97.50-120$

$-1.5x=-22.5$

$\frac{-1.5x}{-1.5}=\frac{-22.5}{-1.5}$

$x=15$

Therefore, the number of 10-oz boxes sold be Jillian is 15.

Now, we will substitute $x=15$ in equation (1) to solve for y.

$15+y=24$

$15-15+y=24-15$

$y=9$

Therefore, the number of 16-oz boxes sold be Jillian is 9.

Find the volume of these solid 20mm 3.7mm 41mm

Reil [10]

The volume of the solid is which is a cone is 100.48 $km^{3}$ .

Given a cone of radius 4 km and height being 6 km.

We are told to find the volume of the cone.

Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.

Volume of cone is 1/3 $\pi r^{2} h$ .

Volume =1/3 $\pi 4^{2} *6$

=1/3 π*16*6

=32π

=32*3.14

=100.48 $km^{3}$

Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48 $km^{3}$ .

Verdich [7]

Option B) 3 hours is the time spent by Jenna on the e-mail this week.

Step-by-step explanation:

Jenna spent 30 hours on the computer this week.

The amount of time she spends on computer to work on various fields in given in the pie-chart.

This 30 hours represents her 100% work on computer.

From the figure shown,

She spent 10% of her total work on e-mail.

Therefore, 10% of 30 is the work done in hours by her on e-mail.

⇒ (10/100) × 30

⇒ 0.1 × 30

⇒ 3 hours

∴ Option B) 3 hours is the time spent by Jenna on the e-mail this week.
