Answer:

[tex] \frac{2 \sqrt{177} }{5} [/tex]

or

5.32cm correct to 2 decimal places

Step-by-step explanation:

This is a right angled triangle from what I know so we have to apply pythagoras theorem.

[tex] {7.1}^{2} = {a}^{2} + {4.7}^{2} [/tex]

we need to rearrange this to find a²

[tex] {a}^{2} = {7.1}^{2} - {4.7}^{2} [/tex]

[tex]a = \sqrt{ \frac{708}{25} } [/tex]

This can either be written as a fraction or decimal.

[tex]a = \frac{2 \sqrt{177} }{5} [/tex]

OR

[tex]a = 5.32[/tex]

correct to 2 decimal places

Answer:

$800 in a week

Step-by-step explanation:

to find how much she had after giving it to her mother we can use the equation 240 / 75%

240 / 75% = 320

then you must find how much she had before she gave part of her wage to her mother

320 / 40% = 800

she earns $800 in a week

Answer:

800$

Step-by-step explanation:

Answer:

25,800

Step-by-step explanation:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

75,200 - 49, 400 = 25,800

Answer:

4

Step-by-step explanation:

.3 is less than halfway between 4 and 5.

Answer:

I believe it would be 4.

Step-by-step explanation:

If you are rounding it to the nearest whole number, you would want to take a look at the number next to it.

4 or less, let it rest (do not bump up the number)

5 or more, raise the score (bump the number higher by one)

Thus, the answer would be 4!

Hi!

Answer:

A) 331.24

Step-by-step explanation:

To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

Answer:

27

Step-by-step explanation:

CDE is a right angle so the sum of CDF and FDE is equal to 90

2x + x + 9 = 90 add like terms

3x + 9 = 90 subtract 9 from both sides

3x = 81 divide both sides by 3

x = 27

Answer: I would say D.

Its a guess ok, i have no idea.

Answer:

52 degrees

Step-by-step explanation:

We're given:

The sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.

Knowing this, we can form the following equation and solve for x:

[tex]5x-2+2x=180\\7x-2=180\\7x=182\\x=26[/tex]

Therefore, x is 26. Find 2x to find the measure of Angle 2:

[tex]2*26=52[/tex]

Therefore, Angle 2 has a measure of 52 degrees.

Answer:

52

Step-by-step explanation:

Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary

m<1 + m<2 = 180

5x - 2 + 2x = 180 add like terms

7x - 2 = 180 add 2 to both sides

7x = 182 divide both sides by 7

x = 26

To find the measure of angle 2 replace x with the value we found

m<2 = 2x

2*26 = 52

Answer:

F = (1/2, 2 3/4)

G = (1/2, 2 1/4)

H = (1, 1 3/4)

I = (3/4, 1 1/4)

J = (1 1/4, 3/4)

Step-by-step explanation:

Do you still need help?

F = (1/2, 2 3/4)

G = (1/2, 2 1/4)

H = (1, 1 3/4)

I = (3/4, 1 1/4)

J = (1 1/4, 3/4)

The total number of ski trails based on the information about the fraction is 12 ski trails.

The difference in length between the longest ski trail and the shortest ski trail will be:

= 3 1/8 - 2 1/4

= 3 1/8 - 2 2/8

= 7/8 miles

The total length of the ski trials that are 2 7/8 miles long will be:

= 3 × (2 7/8)

= 3 × 23/8

= 69/8

= 8 5/8 miles

The sum of the shortest and longest trail will be:

= 3 1/8 + 2 1/4

= 3 1/8 + 2 2/8

= 5 3/8

Lastly, the longest ski trail isn't more than three times the shortest trail. Therefore, Eli is correct.
