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]

Important information:

Two equations [tex]a_1x+b_1y+c_1=0[/tex] and [tex]a_2x+b_2y+c_2=0[/tex] has infinitely many

solutions if [tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex].

In the given equations, [tex]a_1=20,b_1=-9,c_1=-5,a_2=4,b_2=-6,c_2=2[/tex].

Answer:

124

Step-by-step explanation:

180-56

Answer:

124

Step-by-step explanation:

You see the triangle angles always need to equal to 180. We can see that A is 33 and C is 23 so add these two and you get 56. Now what's the difference between 56 and 180? its 124

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!

The question is worded weirdly, but the mean (average) is 3.3. The median is 4. The median would probably represent this better.

Step-by-step explanation:

The median is found by adding all of the numbers in the data set and then dividing by how many numbers there are.

The median is the middle number, which you find by alternately crossing out the biggest and smallest numbers.

Answer:

D. 14

Step-by-step explanation:

To find the first triangle's area you need the formula: A = l * W * 1/2

4 * 4 * 0.5 = 8

and

4 * 3 * 1/2 = 6

8 + 6 = 14

Answer:

3 units right, 4 down = (x+3, y-4)

3 units left, 4 up = (x-3, y+4)

4 units right, 3 down = (x+4, y-3)

Answer:

A

Step-by-step explanation:

A)  As Juan used 1/2 of a 1/4 of a quart of milk, he has 1/2 of 1/4 of a quart left (since 1/2 + 1/2 = 1). We need to find 1/2 of 1/4, so multiply:

⇒ 1/4 x 1/2 = 1/8  of a quart

B)  Juan has 1/4 of a quart of milk and bought another 1/2 of a quart of milk, so to find the total amount, add both quantities:

⇒ 1/4 + 1/2 = 3/4  of a quart

C)  Juan had 1/2 of a quart of milk and used 1/4 of a quart on his cereal, so he had left:

⇒ 1/2 - 1/4 = 1/4  of a quart

D)  Juan drank 1/2 a quart of milk and put 1/4 quart of milk on his cereal, so in total he used:

⇒ 1/2 + 1/4 = 3/4 of a quart

Comparing expression, problem A can be solved by the given expression.

Answer:

3.14 cm²

Step-by-step explanation:

Given that,

→ Diameter = 2 cm

→ Radius (r) = 2/2 = 1 cm

Formula we use,

→ Area of circle = πr²

Then the area of circle will be,

→ πr²

→ 3.14 × 1 × 1

→ 3.14 cm²

Hence, the solution is 3.14 cm².

Answer:

π

Step-by-step explanation:

Area of a circle = [tex]r^{2}[/tex]π

1. Find the radius.

You should view the "length" of this circle as the diameter of the circle. So the diameter of the circle is 2 cm ⇒ r = [tex]\frac{2}{2}[/tex] where the numerator is the diameter of the circle (2) and the denominator is always 2. So the radius is 1. The radius is half the length of the diameter.

2. Substitute the values.

A = [tex](1)^{2}[/tex]π          Always put the radius in parentheses before evaluating.

A = π         [tex]1^{2}[/tex] = 1 and 1 · π = π

Let's take this number:

WHY this number fits the criteria?

How did I find this number?

(note: there are MANY answers to this question)

Given

Perimeter = (32x + 8)

To Find

Length of the Patio

We Know,

[tex] \text{Perimeter of Square = 4 × sides}[/tex]

[tex] \text{ 32x + 8} = 4 \times \text{sides} \\ \\ \fbox{dividing each side with 4} \\ \\ \implies \text{( 32x} \div 4) + (8 \div 4) = \frac{4 \times \text{sides}} {4} \\ \\ \implies \text{8x + 2} = \frac{ \cancel4 \times \text{sides}} { \cancel4} \\ \\ \implies \text{sides} = \text{8x + 2}[/tex]

[tex]\therefore \text{ Length of the Patio} = \text \red{ \underline{8x + 2 feet}}[/tex]

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.

#SPJ1

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
