Going into the final​ exam, which will count as two​ tests, has test scores of 77 , 82, 72 , 63 and 92 What score does need on the final in order to have an average score of​ 80?

the correct answer would be 54 degrees. you would subtract 90 and 54 from 360, leaving 108. you would have to divide by 2 since we have 1 and 2 angles, that leaves 54. hope this helps!

Answer:

last option 180 degrees

Step-by-step explanation:

let ∠1 and angle ∠2 be 2x as both are of same angles

angle sum proprty = 360

90 + 54+ ∠1 +∠2 = 360

144 + 2x = 360

2x = 360 - 144

2x = 216

x = 216 ÷ 2

x = 108

∠2 = 108 degrees

Answer:

20

Step-by-step explanation:

This is because If we are looking for arena then we need to multiply the base by the height if we do this then our answer will be 40, but because we are looking at a triangle we will have to devide that by 2. Which will give us the final answer of 20

Answer:

area = 20 inches

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height

= [tex]\frac{1}{2}[/tex] × 8 ×5

= [tex]\frac{1}{2}[/tex] × 40

= [tex]\frac{40}{2}[/tex]

= 20

area = 20 inches

Answer:

V = 192π cm³ ≈ 603 cm³

Step-by-step explanation:

V = πR²h

V = π(8/2)²(12)

V = 192π cm³ ≈ 603 cm³

J = 3   Hooray, but why?

Answer:

Step-by-step explanation:

Radius r = 4 cm

Height h = 12 cm

Volume = πr²h = 192π cm³ ≈ 576 cm³

Answer:

6 * 100 = 600

14 * 10  = 140

12 * 1    = 12

Answer:

  a⁶b⁴

Step-by-step explanation:

The relevant rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

__

These let us simplify the expression as follows:

  [tex](a^3b^2)^2=(a^3)^2(b^2)^2=a^{3\cdot2}b^{2\cdot2}=\boxed{a^6b^4}[/tex]

_____

Additional comment

It might be helpful to remember that an exponent signifies repeated multiplication.

  a·a·a = a³ . . . . . . 'a' is a factor 3 times, so the exponent is 3.

Similarly, ...

  (a³)² = (a³)·(a³) = (a·a·a)·(a·a·a) = a⁶

Answer:

Explaination down below

Step-by-step explanation:

Before you start this question, make sure you know this rule. When multiplying fractions, Multiply the numerator by the other numerator and multiply the denominator by the other one.

[tex]\frac{1}{5}[/tex] x [tex]\frac{1}{2}[/tex]. 1*1=1, so one is the numerator. 2*5= 10 so 10 is the denominator.

The final answer is [tex]\frac{1}{10}[/tex].

Answer:

225

Step-by-step explanation:

x + y + z = 1305

x = 360

y = 360×2 = 720

z = 1305 - 360 - 720 = 225

Answer:

225

Step-by-step explanation:

since the first number is 360 and the second number is twice the first number meaning it's (360×2) which is 720,you have to add the two and subtract by 1305 to find the value of the third number(which I have represented by x)

360+720+x=1305

1080+x=1305

x=1305-1080

=225

therefore the third number is 225,you can prove it by adding the three to see whether you will get 1305.

Answer:

15/22

Step-by-step explanation:

3/11 ÷ 2/5

3/11 x 5/2

3/11 x 5/2 = 15/22

3/11 divided by 2/5 is equal to 15/22.

Here, we have,

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by flipping the numerator and denominator.

Let's calculate 3/11 divided by 2/5:

(3/11) ÷ (2/5)

To divide, we multiply by the reciprocal:

(3/11) * (5/2)

Now, multiply the numerators together and the denominators together:

(3 * 5) / (11 * 2) = 15/22

Therefore, 3/11 divided by 2/5 is equal to 15/22.

If the endpoints are [tex]X(-4,3)[/tex] and [tex]Z(6,-2)[/tex]and  point [tex]Y(h.,k)[/tex] divides the this segment in the ratio of [tex]1:5[/tex].

(h, k) = [tex](\frac{1(6)+(5)(-4)}{1+5},\frac{1(-2)+5(3)}{1+5})[/tex]

Step-by-step explanation:

z = 5y/8

x = 3y/8

2x + 3y - z = 50

6y/8 + 3y - 5y/8 = 50

6y/8 + 24y/8 - 5y/8 = 50

25y/8 = 50

25y = 400

y = 16

x = 3y/8 = 3×16/8 = 3×2 = 6

z = 5y/8 = 5×16/8 = 5×2 = 10

Answer:

96

Step-by-step explanation:

The mean number of 5 nights is 90. It means that the quantity of guests who came these nights is 90*5=450

The mean number of the six nights is 91. So the quantity of guests is 6*91=546

546-450= 96- the quantity of guests that came on the extra night

Answer:

1.5 pounds of apples are in each pie

Step-by-step explanation:

to show our work, lets multiply 1.5 by 2.

(this is the distributive property. the method shown in the image is long multiplication, but they follow the same idea)

for the sake of simplicity, we will write 1.5 as 15.

5×2=10

10×2=20

10+20=30

dont forget the decimal point! since we have one digit in the decimal place, we move the decimal behind one digit in 30.

30.0 --> 3.0 or simply, 3.

this proves that there are 1.5 pounds of apples in each pie. hope this goes more in depth !!! :)
