Answer:

  maybe

Step-by-step explanation:

Dora is apparently assuming the dimensions are integers. In that case she is correct.

If the dimensions are unconstrained, the perimeter will be largest when a pair of opposite sides will be the smallest measure allowed.

For some perimeter P and side length x, the area is ...

  A = x(P/2 -x)

Conversely, the perimeter for a given area is ...

  P = 2(A/x +x)

This gets very large when x gets very small, so Dora is correct in saying that the side lengths that are as small as they can be will result in the largest perimeter. We have no way of telling if her assumption of integer side lengths is appropriate. If it is not, her statement makes no sense.

Answer:

Approximately 87 minutes

Step-by-step explanation:

So first see how much of the reading 41 minutes is. It is 47%.

So now to find out how much 100% is, first find out how much 1% is.

Just divide by 47.

1% = [tex]\frac{41}{47}[/tex]

And then multiply by 100 to get 100%

[tex]\frac{4100}{47}[/tex]

That is 87.2340425532

Which is 87

Answer: 8.8 pounds.

Step-by-step explanation:

Hi, to answer this question, first we have to divide the total weight loss in a week (28 kg) by 7 (days in a week).

28 /7 = 4 kg per day

The group lost 4 kg each day.

Finally we have to convert the result into pounds.

Since 1 kg = 2.2 pounds

4 kg x 2.2 = 8.8 pounds.

Answer:

a e

Step-by-step explanation:

The value of x according to the equation is -7/4 and the equivalent equations that Katrina might use is x - 2x - 6 = 8x + 12 - x  - 4

Given the equation solved by Katrina expressed as;

x - 2 (x + 3) = 4 (2 x + 3) - (x + 4).

Expand using distributive law;

x - 2x - 6 = 4(2x) + 4(3) - x - 4

x - 2x - 6 = 8x + 12 - x  - 4

-x - 6 = 7x + 8

-x - 7x = 8 + 6

-8x = 14

x = 14/-8

x = -7/4

Hence the value of x according to the equation is -7/4 and the equivalent equations that Katrina might use is x - 2x - 6 = 8x + 12 - x  - 4

Answer:

The first offer: 100.80 for 4kg

Step-by-step explanation:

To find the best offer, we just need to find the price per kilogram, and we do this by dividing the price by the number of kg:

100.80 for 4kg: 100.8/4 = 25.2 per kg

170.50 for 5kg: 170.5/5 = 34.1 per kg

260.60 for 6kg: 260.6/6 = 43.43 per kg

320.40 for 7kg: 320.4/7 = 45.77 per kg

The first offer has the smaller price per kg, so it is the best offer.

Answer: About 5.2 Hours

Step-by-step explanation:

550= 35 x 3x

183.33= 35x

5.2 = x

Answer:

y = -3

Step-by-step explanation:

So, first you need to plug in -4y-4 for x. So, 5(-4y-4) + 2y=34. Now, use the distributive property and now it will become -20y -20 + 2y = 34. Add like terms which would be -20y + 2y = -18y. Now the equation is -18y - 20 = 34. Now use inverse operations and add 20 to both sides. Then the equation will be -18y = 54. When you divide -18 on both sides, you get y=-3.

Hope this helps :)

Answer:

80.4 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opposite/ adjacent

tan 15 = x / 300

Multiply each side by 300

300 tan 15 = x

80.38475773=x

To the nearest tenth

80.4 =x

Answer:

80.4

Step-by-step explanation:

use tan x = opp/adj

tan 15° = x/300 multiply by 300 on both sides

tan 15° * 300 = x

x = 80 .38 ≈80.4

Answer:

6.5

Step-by-step explanation:

In this question, we are tasked with calculating the mean temperature for the first 8 days.

since we we have the mean temperature for the first 7 days, the total temperature is thus 7 * 6 = 42

Now, on the 8th day, temperature is 10, this brings total temperature to 42 + 10 = 52

The mean temperature for the first 8 days ys therefore; 52/8 = 6.5

Answer:

$1.25 for a pound of apples.

Step-by-step explanation:

First I did, 6.35-2.60 to find the cost of JUST the apples. which was 3.75.

then I did 3.75/3 i divided them. It came out to 1.25. SO that means it costs $1.25 for a pound of apples.

Hello!

[tex]\boxed{ \bf 1.~l~=~9.25~cm;~A~=~55.5~cm^2~matches~with~the~last~option~w~=~6~cm.}[/tex]

[tex]\boxed{ \bf 2.~l~=~7.5~cm;~A~=~48.75~cm^2~matches~with~the~second~option~w~=~6.5~cm.}[/tex]

We already know that the formula for area of a rectangle is A = l × w.

Notice how the width and the length are being multiplied to find the area.

Well, to find the width, we must do the opposite of multiplication, which is division.

Since we already have the length, all we have to do is divide the area by the length for each of the questions.

1:

A = l × w

55.5 = 9.25 × w

[tex]\frac{55.5}{9.25}[/tex] = 6

2:

A = l × w

48.75 = 7.5 × w

[tex]\frac{48.75}{7.5}[/tex] = 6.5

3:

A = l × w

44 = 5 × w

[tex]\frac{44}{5}[/tex] = 8.8

4:

A = l × w

31.25 = 5 × w

[tex]\frac{31.25}{5}[/tex] = 6.25

Answer:

h(x) = (x + 5)² − 18

Step-by-step explanation:

h(x) = 7 + 10x + x²

h(x) = x² + 10x + 7

Complete the square. (10/2)² = 25, so:

h(x) = x² + 10x + 25 − 18

h(x) = (x + 5)² − 18

Answer:

$1,349.8

Step-by-step explanation:

Using the formula given:

A=Pe^rt, where

A= ending amount

P= beginning amount

e= Euler’s number that is approximately 2.718

r= rate: 3%=0.03

t= time: 10 years

A= $1,000*(e^0.03*10)

A= $1,000*(e^0.3)

A= $1,349.8

According to this, the answer is that the balance after 10 years is $1,349.8.

If the best player makes 70% of all free throws, then this player would be expected to make 70% of the next 60 free throws, which is 42. (The equation that goes with this is [tex]\frac{70}{100}=\frac{x}{60}.[/tex])

Similarly, the second-best player would make 65% of 60 throws, which is 39, and the third-best player would make 55% of 60 throws, which is 33.
