Answer: 1440°

Step-by-step explanation:

To solve the above question, we'll use the formula (n-2) × 180. In this question, we are told that it has 10 sides. This implies that n= 10. Therefore, using the formula goes thus:

= (n - 2) × 180

where, n = 10

= (10 - 2) × 180

= 8 × 180

= 1440

Answer:

a.

[tex]h=\dfrac{2A}{b}[/tex]

b.

A = 220 mm²

b = 20 mm

[tex]h=\dfrac{2 \cdot 220}{20}=22 \: {mm}[/tex]

Answer:

A=1/2bh

2*A=1/2bh*2

2A/b=bh/b

h=2A/b

b)h=2(220)/20

height=22mm

8-5=3, 1-(-7)=8, 3^2+8^2=73, and the square root of 73 is 8.5

Answer:

5/9

Step-by-step explanation: If you find a common denominator ( i found 135 ) and you multiply each numerator by the number u multiplied the denominator to get the common denominator, you can see that 5/9 is greater. hope this helps and sorry if that was confusing

Answer:

5/9 is greater

Step-by-step explanation:

As numerator of second ratio is greater, Hence, 5/9 is greater.

Answer:

Step-by-step explanation:

According to sine law of trigonometric functions,

sin(α)/a =sin(β)/b

hence using this

sin(18)/y = sin(x)/2y

sin(x)=2*sin(18)

sin(x)=2*0.309

sin(x)= 0.618

x=sin-1(0.618)     ( sin-1  is sine inverse)

x=38.17 °

x + 80 = 180 - (64 + 36)

x + 80 = 180 - 100

x + 80 = 80

x = 0

Answer:

x plus 1

Step-by-step explanation:

Answer:

x+1

Step-by-step explanation:

if you simplify the equation, you will get x+1

first, you take the parentheses away.  The equation becomes

3x-2x-4+5

then you combine like terms

x+1

Answer:

If you're multiplying them: 34x * 30x = 1020x^2

If you're adding them: 34x + 30x = 64x

If you're subtracting them: 34x - 30x = 4x

Answer:

a.) since he already has 40 in his savings account, start the line at (0,40) on the y-axis and then go up 15 every hour

b.) 15 or 15/1

c.) for each hour Donny spends working, the amount of money he has go up by 15

d.) (0,40)

e.) the vertical intercept or (y-intercept) is (0,40) because this is how much money Donny already has in savings

Answer:

a= 22.5

b= 37.5

Step-by-step explanation:

In △BCD:

Applying Pythagoras' Theorem,

a² +30²= b²

a² +900= b² -----(1)

In △ABC:

Applying Pythagoras' Theorem,

b² +50²= (40 +a)² -----(2)

Substitute (1) into (2):

a² +900 +50²= 40² +2(40)(a) +a² (expand bracket)

a² +900 +2500= 1600 +80a +a²

a² +3400= a² +80a +1600 (simplify)

a² +3400 -a² -80a -1600= 0 (bring everything to 1 side)

-80a +1800= 0

80a= 1800 (+80 on both sides)

a= 1800 ÷80

a= 22.5

Subst. a= 22.5 into (1):

22.5² +900= b²

b²= 506.25 +900

b²= 1406.25

b= √1406.25 (square root both sides)

b= 37.5 (reject negative value since b is a length)

☆(a +b)²= a² +2ab +b²

Answer:

y + 1 = 4/3(x - 9)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

Substitute the numbers into the equation:

y - (-1) = 4/3(x - 9)

y + 1 = 4/3(x - 9)

Let hours = x

She can work a maximum of 30 hours so x can be any number from 30 or below.

The inequality would be: X <= 30

Answer:

Let the maximum time be x

She can work 30 hrs or below ( maximum of 30 hrs)

Therefore, the equation is

Step-by-step explanation:

320 girls & 250 boys

0.2 probability     0.1 probability

320 x 0.2 = 64

250 x 0.1 = 25

64 + 25 = 89

There are approximately 89 students in the school that are left-handed.

Answer

89% of the people are left handed

Step-by-Step Explanation

To find this you have to first do 320 x 0.2

320 x 0.2= 64

To find it for boys you have to do 250 x 0.1.

250 x 0.1= 25

SO, the answer is 89%. 64% of girls and 25% of boys

Hope i helped :D
