Since the line goes up from left to right, the graph is increasing

Answer 2

Answer:

Answer:

Increasing ; Option C

Step-by-step explanation:

We can tell that this graph does increase, but let us prove so, through slope;

$If Slope - Positive, - Graph Increases,\nIf Slope - Negative - Graph Decreases,\nIf Slope = 0 - Constant,\n\nSlope of Line = 3 / 1 = 3, ( Positive ),\nConclusion ; Graph - Increasing$

Solution ; Increasing

Which shows the dimensions of two rectangular prisms that have volumes of 240 ft3 but different surface areas?A.
8 ft by 5 ft by 6 ft;
5 ft by 6 ft by 8 ft

B.
8 ft by 5 ft by 6 ft;
10 ft by 8 ft by 3 ft

C.
15 ft by 8 ft by 2 ft;
6 ft by 4 ft by 15 ft

D.
12 ft by 6 ft by 5 ft;
8 ft by 10 ft by 3 ft

Answers

Given:
Volume of rectangular prism: width * height * length
Surface area of rectangular prism : 2(wl + hl + lw)

A.
8 ft by 5 ft by 6 ft; ⇒ V = 240 ; S.A = 236
5 ft by 6 ft by 8 ft; ⇒ V = 240 ; S.A = 236

B.
8 ft by 5 ft by 6 ft; ⇒ V = 240 ; S.A. = 236
10 ft by 8 ft by 3 ft ⇒ V = 240 ; S.A = 268
THIS IS THE ANSWER. SAME VOLUME: DIFFERENT SURFACE AREA.

C.
15 ft by 8 ft by 2 ft; ⇒ V = 240 ; S.A = 332
6 ft by 4 ft by 15 ft ⇒ V = 360 ; S.A = 348

D.
12 ft by 6 ft by 5 ft; ⇒ V = 360 ; SA = 324
8 ft by 10 ft by 3 ft ⇒ V = 240 ; SA = 268

Lisa drinks 0.55 L of milk everyday . How much milk does she drink in 11 days? Write your answer in milliliters

Answers

Answer:

She will drink 6050mL of milk in 11 days.

Step-by-step explanation:

Multiply by the amount of milk she drinks and how many days there are.

0.55L x 11 = 6.05L

Convert the answer into milliliters (multiply by 1000 because there are 1000mL in 1L).

6.05L x 1000 = 6050mL

Therefore, Lisa will drink 6050mL of milk in 11 days.

A dog is leashed to the corner of a house with a 15 foot leash. How much running area does the dog have? Round your answer to the nearest square foot.

Answers

If the dog were on a 15-ft leash tied to a stake in the ground
out in the middle of a field, then he could cover every blade
of grass in a 15-ft circle. The area of a circle is (pi R²), so
he would have free range over (pi · 15²) square feet of area.

Sadly, he's not out in the middle of a field. He's tied to the corner
of the house. So he can't cover the whole circle, because the house
blocks a quarter of the circle. The dog only has access to

   (3/4) of (pi R²)

   = (0.75) · π · (15²)

   = (0.75 · π · 225) = 530 square feet (rounded)

David charges $15 plus $5.50 per hour to mow lawns. Ari charges $12 plus $6.25 per hour to mow lawns. In what situations is Ari's charge greater than or equal to David's charge?

Answers

Let's write an equation for what David charges.
Let x equal the number of hours he has been moving lawns and y be the charge.
Every hour, you must add another $5.50.
This is the same as multiplying the number of hours by 5.50.
We also need to add that $15 at the beginning. This leaves our equation as
$y=5.50x+15$

Now, let's write one for Ari.
6.25 per hour...6.25x.
Add the 12 and we get
$y=12x+6.25$

To find when the two are equal, we can set up this equation:
$5.50x+15=12x+6.25$

Now, let's simplify. Since all of our decimals are either halves or quarters, you can multiply everything by 4 to get rid of them.
$22x+60=48x+25$

Subtract 22x from each side to get x on one side.
$60=26x+25$

Subtract 26 from each side to get x alone.
$35=26x$

Divide by 26 to find the value of x.
$x=35/26\approx1.346$

What does this tell us? Well, it tells us that when our number of hours reaches 1.346, their charges are equal.

(The .346 can be estimated as around 20 minutes because it's pretty close to .333, or a third of an hour. This puts 1.346 hours at an hour and 20 minutes.)

We still haven't answered one part of the question, though...after that 1:20 time frame, who is charging more? Well, let's say we had them mow lawns for two hours. Using 2 for x in those earlier equations gives us these values:

$David:\ y=5.50(2)+15=11+15=26$
$Ari:\ y=6.25(2)+12=13+12=25$

It seems that Ari charges less than David past that 1:20 point.

Since the question asked "when is Ari's charge greater than or equal to David's" we would respond by saying whenever he mows lawns for less than an hour and 20 minutes.
