Step-by-step explanation:

. citizen of the represented state

Answer:

1083

Step-by-step explanation:

The formula for the nth term of a sequence is a+(n - 1 )d, where a is the first term and d is the difference between each term. Here, a is -7 and d is 10 (terms go up by ten each time).

So, the nth term = -7+(n-1)10 = -7+10n-10 = 10n-17

So, the 110th term = 10(110)-17=1100-17=1083

Answer:

c

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

Answer:

As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.

Step-by-step explanation:

Here n= 20

Sample mean GPA = x`= 2.84

Standard mean GPA = u= 2.55

Standard deviation = s=  0.45.

Level of Significance.= ∝ = 0.01

The hypothesis are formulated as

H0: u1=u2   i.e the GPA of night students is same as the mean GPA of day students

against the claim

Ha: u1≠u2

i.e the GPA of night students is different from the mea GPA of day students

For two tailed test  the critical value is  z ≥ z∝/2= ± 2.58

The test statistic

Z= x`-u/s/√n

z= 2.84-2.55/0.45/√20

z= 0.1441

As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.

Answer:

He had origanlly had 68 altogether

Step-by-step explanation:

Because if u count the scrateched ones which was 6 is now 62 then add the other six because there was 12 and his brother scrateched half which is basically 12 / 2 = 6 so if u add the six is 68

What Im basically saying is 56 + 12 = 68

Answer:

theyre correct

Step-by-step explanation:

We know that the sum of a straight line is 180° . So here there are 3 angles in a straight line . And the sum is 180° . So that ,

[tex]\tt\to Sum_{(angles \ of \ a \ straight \ line)}= 180^o \\\\\tt \to 7x + 8x + 44.4^o = 180^o \\\\\tt\to 15x = 180^o - 44.4^o \\\\\tt\to 15x = 135.6^o \\\\\tt\to x =\dfrac{135.6^o}{15}\\\\\tt\to \boxed{\orange{\tt x = 9.04^{\circ} \approx 9^{\circ} }}[/tex]

So the measure of angle that is highlighted will be 8x = 8(9) = 72°

Answer:

72.32degrees

x is 9.04

Step-by-step explanation:

7×9.04=63.28

8×9.04=72.32

44.4+63.28+72.32=180

Answer:

equation is y=20(3)^x

Step-by-step explanation:

example:

Solve for x over the integers:

20 (3)^x = 4860

Divide both sides by 20:

3^x = 243

243 = 3^5:

3^x = 3^5

Equate exponents of 3 on both sides:

Answer:

x = 5 hours open with 4860 guest

Answer: $536.40

Step-by-step explanation:

8.94 * 2 = 17.88

8.94(40) + 17.88(10)

357.60 + 178.80 = $536.40

Answer:

log ( 28 )

13 √ 25

log

( 1/ 2 )

Step-by-step explanation:

To solve this, we will use this property of logarithms:

If x= a ^ y

then log an (x) = y, where a is the base

 So if e^9 = y  , or y = e^9

then log e (y) = 9

NB: log e (y) is also referred to as the natural log of y, or ln y.

So it can also be written as:

Answer: ln y = 9, or log e (y) = 9

Answer:

99°

Step-by-step explanation:

Triangle=180°

Given, 41+40=81

180-81

Answer:

99°

Step-by-step explanation:

Sum of angles in a triangle is supplementary,

x + 41° + 40° = 180°

x + 91° = 180°

x = ( 180 - 91 )

x = 99°

Answer:

23

Step-by-step explanation:

Example:

You have no money, you decide to swipe your credit card to purchase something for $17. Again, you did so for another item paying $24. You are now $41 in debt. Your mom decides to pay for your debt which is $41. You decide to actually go to your part-time job and earn $23. When was the time you had the most money in this example? When you earned the $23 becuase you started with none.

Answer:

23

Step-by-step explanation:

Out of the numbers given:

All positive numbers are greater than negative numbers.

This eliminates -17 and -24.

Comparing 0 to 23:

23 has more value than 0.

0 < 23

This means out of the numbers given, 23 has the greatest value.  

Hope this helps.  

Answer:

14m

Step-by-step explanation:

The expression that shows the number of coupon books:

14*m = 14m

Answer:

14m

Step-by-step explanation:

they say the members are represented by M, and the members sold 14 coupon we can't say it is m + 14 so the answer is 14m

Answer:

It grows 221 centimeters in 13 weeks.

Step-by-step explanation:

Each meter has 100 centimeters.

A coral reef grows 0.17 m every week

So it grows 0.17*100 = 17 cm every week.

How much does it grow in 13 weeks?

17 cm every week for 13 weeks, so

17*13 = 221

It grows 221 centimeters in 13 weeks.

Answer:

x = 5

Step-by-step explanation:

These angles are supplementary so:

9x + 12x + 75 = 180

21x + 75 = 180

21x = 180 - 75

21x = 105

x = 5

Answer:

282.7 cm²

Step-by-step explanation:

Hello There!

To find the area of the shaded area we are going to want to find the area of the whole semi circle and subtract it by the area of the smaller semi circle

To find the area of a semicircle we use this formula

[tex]A=\frac{\pi r^2}{2}[/tex]

where r = radius

For the large semi circle

The radius of the larger semi circle is 18 cm so we plug in 18 into r in the formula

So..

[tex]A=\frac{\pi 18^2}{2} \\18^2=324\\324\pi =1017.87602\\\frac{1017.87602}{2} =508.9380099[/tex]

So the area of the whole semi circle is 508.9380099 cm²

Now to find the area of the smaller semi circle

The radius for the smaller semi circle is 12 cm so we plug in 12 into r in the formula

[tex]A=\frac{12^2\pi }{2} \\12^2=144\\144\pi =452.3893421\\\frac{452.3893421}{2} =226.1946711[/tex]

so the area of the smaller semi circle is 226.1946711cm²

Finally we want to subtract the area of the smaller semi circle from the area of the whole semi circle

508.9380099 - 226.1946711 = 282.7433388

Finally we want to round to the nearest tenth and we get that the area of the rainbow is 282.7 cm²
