He studied about 6 hours each day. Just divide 24.4 by 6 . If you want to give an accurate answer then it would be 6.1

Laura has a backyard that she wants to renovate. Her

miskamm [114]

Answer:

Area of the walkway = 8x + 24

Step-by-step explanation:

Area of the total backyard = $l\times b$

Area of total backyard = $(x+6)\times (x+4) = x^{2} +10x + 24$

Now, Area of the rectangular garden = $l\times b$

Area of the rectangular garden = $x (x+2) = x^{2} + 2x$

Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden

= $(x^{2} +10x +24) - (x^{2} +2x)$

= $x^{2} + 10x +24 - x^{2} -2x$

= 8x + 24

Joey Chestnut is trying to break his own record for eating the most whole hot dogs in 101010 minutes. He needs to eat more than

anygoal [31]

Answer:

$9d+11\frac{1}{4}>72$

Step-by-step explanation:

We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.

Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.

We have been given that after 1 minute, Joey has eaten $11\frac{1}{4}$ hot dogs.

Hot dogs eaten in next 9 minutes would be 9 times d that is $9d$ .

Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: $9d+11\frac{1}{4}$ .

Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:

$9d+11\frac{1}{4}>72$

Therefore, our required inequality would be $9d+11\frac{1}{4}>72$ .

Greg and Lu are building a toy hydraulic crane, as shown in the picture.

iVinArrow [24]

So,

Notice that there is a triangle with two of the angles given. We know that the sum of any triangle's angles will always be 180°. Thus, we can subtract the two given angles from 180, and that will give us the measure of angle ABC.

180 - 20 - 25 = 160 - 25 = 135

The measure of angle ABC is 135°.

The correct option is D.
