Answer:

1/12 miles/minute

Step-by-step explanation:

To figure out how fast ellie runs in 1 minute, we can set up this equation:

5/6 = 10x (x being the speed per minute)

We can divide both sides by 10

5/60 = x

Then simplify the fraction to get:

1/12 = x

sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm.

Strike441 [17]

Answer:

$220$ cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be $2(l+w)$ , where $l$ is the rectangle's length and $w$ is the rectangle's width. We are given that $l=70$ and $w=40$ . Therefore, $2(70+40)=2*110=220$ cm of ribbon will be needed. Hope this helps!

a home improvement store rents it’s delivery truck for $19 for the first 75 minutes and $4.75 for each additional 1/4 hour. if a

Crank

Answer: $42.75

Step-by-step explanation:

Given: A home improvement store rents it’s delivery truck for $19 for the first 75 minutes and $4.75 for each additional 1/4 hour.

Since, 1 hour = 60 minutes

1/4 hour = $\frac{60}{4}=15\ minutes$

If a customer rented the truck at 11:10 am and returned the truck at 1:40 pm the same day, what would his rental cost be

Time taken = 150 minutes

Since charge for first 75 minutes is fixed and charge of $4.75 for each additional 1/4 hour (15 minutes) is given by

The additional charge = $\frac{(150-75)}{15}\times4.75=23.75/tex]The total his rental cost =[tex]19+23.75=$42.75$

Answer:

Step-by-step explanation:

given

16x² + 4 = 0 ( subtract 4 from both sides )

16x² = - 4 ( divide both sides by 16 )

x² = $\frac{-4}{16}$ = - $\frac{1}{4}$

[ take the square root of both sides ]

x = ± $\sqrt{-\frac{1}{4} }$ = ± $\frac{1}{2}$ i ( $\sqrt{-1}$ = i )

A 3-ounce serving of tuna provides 21 grams of protein. Use equivalent ratios to find how many grams of protein are in 9 ounces

laila [671]

Answer:

63 grams of protein.

Step-by-step explanation:

3 ounces = 21 grams of protein.

Question is how many grams are in 9 ounces, you then have to find the ratio that you need to use to find out how many grams of protein are in 9 ounces. Therefor you divide the amount that we don't know the equal amount of grams by the amount we do know the equal amount of grams, giving us the ratio.

9 divided by 3 = ratio (3)

Then use the ratio for the grams of protein.

21 x 3 = 63.
