Answer: 720 deg

Step-by-step explanation:

The given angles are just all the interior angles in 2 quadrilaterals

So since the sum of the int. angles in 1 quadrilateral is 360 deg, the sum in 2 is 720 deg

Answer:

C/8

Step-by-step explanation:

Because the range is the biggest number subtracted by the lowest number and in our data sat 7,15,and 12 15 is the biggest number and 7 is the smallest so what's 15-7?

8 so C

Have a great day.

Answer:

He can buy up to 2 outfits.

Step-by-step explanation:

440.12 + 2(12.86) + 19.26 + 53.96o ≤ 620

53.96o + 485.10 ≤ 620

53.96o ≤ 134.9

o ≤ 2.5

He can buy up to 2 outfits.

Answer:

A

Step-by-step explanation:

[tex]\frac{10}{9+\sqrt{7} }[/tex]

To rationalise the denominator multiply the numerator and denominator by the conjugate of the denominator.

the conjugate of 9 + [tex]\sqrt{7}[/tex] is 9 - [tex]\sqrt{7}[/tex]

= [tex]\frac{10(9-\sqrt{7}) }{(9+\sqrt{7})(9-\sqrt{7}) }[/tex] ← expand denominator using FOIL

= [tex]\frac{90-10\sqrt{7} }{81-7}[/tex]

= [tex]\frac{90-10\sqrt{7} }{74}[/tex] ( divide terms on numerator/ denominator by 2 )

= [tex]\frac{45-5\sqrt{7} }{37}[/tex] → A

Answer:

A[tex]\frac{45-5\sqrt7}{37}[/tex]

Step-by-step explanation:

Easy. First let's multiply numerator and denominator by [tex]9-\sqrt7[/tex] since we will create a difference of squares to get rid of the root, then start doing the calculations

[tex]\frac{10(9-\sqrt7)}{(9+sqrt7)(9-\sqrt7)}=\frac{10(9-\sqrt7)}{81-7} = \frac{10(9-\sqrt7)}{74} =\\\frac{5(9-\sqrt7)}{37}=\frac{45-5\sqrt7}{37}[/tex]

Answer:

w=120°

x=45°

y=30°

Step-by-step explanation:

AT=PR, AR=PT

Therefore, y=30°

y+45°=x+30°

x=45°

In triangle:

y+30°+w=180°

w=120°

Step-by-step explanation:

that will be my answer

Answer:

B. 10cm, 15cm, 24cm

Step-by-step explanation:

The 2 shortest sides of a triangle added together must be longer than the longest side of the triangle.

10cm + 15cm > 24cm, so the answer is B.

Answer:

X=3

Step-by-step explanation:

Work Shown:

A = P*(1+r/n)^(n*t)

A = 4750*(1+0.10/2)^(2*10)

A = 12,603.164099436

A = 12,603.16

That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.

interest = A-P = 12,603.16 - 4,750 = 7,853.16

Total:-

Answer:

26

Step-by-step explanation:

Rectangle J and Rectangle K are similar

You can divide 13 by 3.25

13/3.25=4

If Rectangle J is 4 times bigger than K all you have to do is devide 104 by 4 and you get 26

C. Yes, at negative and positive x‐coordinates or zero

I believe it is this

Answer: b Yes ,at negative x coordinates or zero

Step-by-step explanation:

we can see through the values that the graph will graph on the negative x coordinate or zero

Answer:

6

Step-by-step explanation:

Important info given:

Step 1: We need to determine the length of side A.

Since, these two triangles are similar, let us use the property of similarity of triangles to determine the length of side A.

Therefore we have:

[tex]\frac{8}{4} = \frac{a}{3}[/tex]

Step 2: Multiplying by 3, and then we have:

[tex]\frac{8*3}{4}=a[/tex]

[tex]\frac{24}{4}=a[/tex]

Step 3: Simplify, and we get:

6 = a

Hence, the length of side A is 6 cm.

the perimeter of a 5ft by 8ft rectangle is 26ft

Step-by-step explanation:

Hope this helps!!!

-Liyah

Answer:

26ft

Step-by-step explanation:

The formula for the perimeter of a rectangle is P= 2w + 2l

w= 5ft and l= 8ft

so P= 2 x 5 + 2 x 8

= 26ft

Answer:

2x[tex]x^{2}[/tex]-8x+2

Step-by-step explanation:

Answer:

X=7

Step-by-step explanation:

Both are equal angles( the little 2 arrows prove that) so we set up the equation like this

75=11x-2

We need to isolate x to solve for it so we add 2 to both side since it's the opposite of subtraction.

our equation will then look like this

77=11x

last but not least, we divide 11 to both sides since it's the opposite of multiplication which 11 and X are doing

the answer is 7
