9. What is the value
of the expression?
21.3 + (-34.87)

Answer:

The answer would be 6º

Step-by-step explanation:

first we know that a straight lin is always 180º

so since we know that the angle outside of the triangle is 110º we can do 180º -110º

then we get the measuerment for angle C :70º

since we dont know the measurements of the other angles but know that a full triangle is equal to 180º we make this equation

2+6x+12x+70=180

then we solve

72+18x=180

-72         -72

18x=108

/18    /18

x=6

then we plug in the x value to find the angle measurement

2+6(6)

2+36

38º

your answer is m<CAB is 38º

Answer:

9\sqrt{2}

Step-by-step explanation:

this is a 30-60-90 triangle so

the side opposite of 30 is x and the opposite side of 60 is x[tex]\sqrt{2}[/tex]. then the side opposite 90 is 2x.

so if 9=x then a=x\sqrt{2}

9\sqrt{2} is the side length of a

Step-by-step explanation:

Answer:

Sugar | Flour

¼ | 1

½ | 2

⅝ | 2½

4 | 16

Step-by-step explanation:

¼ part of sugar = 1 part flour (given)

Ratio of sugar to flour = ¼ : 1

Use this proportion to complete the table.

✔️Sugar to flour = ¼ : 1

½ : x = ¼ : 1

½/x = ¼/1

cross multiply

x*¼ = 1*½

x/4 = ½

Multiply both sides by 4

x = ½*4

x = 2

✔️Sugar to flour = ¼ : 1

x : 2½ = ¼ : 1

x : ⁵/2 = ¼ : 1

x/⁵/2 = ¼/1

Cross multiply

x*1 = ¼*⁵/2

x = ⅝

✔️Sugar to flour = ¼ : 1

4 : x = ¼ : 1

⁴/x = ¼/1

Cross multiply

x*¼ = 1*4

x/4 = 4

Multiply both sides by 4

x = 4*4

x = 16

Answer:

[tex]Each\ cut = 8ft\ 2in[/tex]

Step-by-step explanation:

Given

[tex]Length = 32ft\ 8in[/tex]

[tex]Cuts = 4[/tex]

Required

Determine the length of each cut

This is calculated by dividing the total length by the number of cuts.

So, we have:

[tex]Each\ cut = \frac{Length}{Cuts}[/tex]

[tex]Each\ cut = \frac{32ft\ 8in}{4}[/tex]

Split:

[tex]Each\ cut = \frac{32ft}{4} + \frac{8in}{4}[/tex]

[tex]Each\ cut = 8ft+ 2in[/tex]

[tex]Each\ cut = 8ft\ 2in[/tex]

Answer:

Step-by-step explanation:

Since one of zero's is complex number, its conjugate should also be a zero of the given polynomial.

The polynomial is going to be:

Substitute zero's:

Step-by-step explanation:

n = 52

x bar = 122.31

standard deviation sd = 38.75

1. the hypothesis:

null hypothesis

h0: μ ≤ 35

alternative hypothesis

h1: μ > 35

2.

we have been given the sd of the sample but not that of the population. so what we are supposed to use here is the t test and not the z test. the following conditions have to be met.

3.

= [tex]\frac{122.31-35}{38.75/\sqrt{52} }[/tex]

= 87.31/5.37

= 16.26

using the T distribution function in excel, the p value was calculated and found to be approximately equal to 0.

TDIST(16.26, 51, 1)

since p value is very small we reject the null and accept the alternate hypothesis.

4. from the result above the answer to this question is yes

Answer:

1hr 5mins

Step-by-step explanation:

thanks. for the free points

3 17 to 4 17 one HR

4 17 to 4 22 5 mins

total is one hour plus five mins

so 1 hr 5 mins

Answer:

1 hour and 5 minutes

Step-by-step explanation:

Between 4:22 pm and 3:17 pm, 1 hour has passed.

3:17 + 1 hour = 4:17

Between 4:17 pm and 4:22 pm, 5 minutes has passed.

4:17 + 5 minutes = 4:22

Therefore, Angela has studied for 1 hour and 5 minutes.

Answer:

252cm²

Step-by-step explanation:

This figure consists of 2 trapeziums.

Area of a trapezium= (The sum of the parallel side/2)× height

Explanation:

[(16+20)÷2]×7

[36÷2]×7

18×7

126cm²

Since the 2 trapezium have the same value we will just multiply the answer by 2.

126×2

252cm²

The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula

m = (y2 - y1)/(x2 - x1)

m = (1 - (-3))/(3 - 1)

m = 4/2

m = 2

Therefore the slope, or the average rate of change, between these points is 2.

Answer:

1 and 6

Step-by-step explanation:

it is just like the roots of a polynomial, since [tex]\sqrt{x-1}[/tex](x-6)^2=0

we can separate the two pieces of the problem

\sqrt{x-1} =0

square both sides to get

x-1=0.   x=1

(x-6)^2=0

square root both sides and get

x-6=0

x=6

so the two inflection points of the equation are 6 and 1

Hi there! Your answer is y = 2x-3

Please see an explanation for a better and clear understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

For an easy understanding to "proportional equation", It is basically an equation that is in form of y = mx + b where b = 0. Therefore, when b = 0 - Our new equation would be y = mx.

Other choices are in form of y = mx while the first choice isn't in the form of y = mx.

To be a proportional function or equation, the equation must be in the form of y = mx only.

The question asks which equation Is not proportional. Hence, the answer is the first choice.
