Step-by-step explanation:

Answer:

angle HEG = 12 degrees

Step-by-step explanation:

A line is 180 degrees. Since there is a right angle there, you know that angleHEG and 78 added together is 90degrees

x + 78 = 90         >> subtract 78 from both sides

x = 12

angle HEG = 12 degrees

Answer:

18 degrees

Step-by-step explanation:

There is a little box on the left that indicates both angles together make a 90 degree angle so you just have to do 90 - 78 to get the answer.

Step-by-step explanation:

I took the test and double checked on my calculator.

Answer:

Step-by-step explanation:

It was 12 take away 210 add 20 to 3243

Answer:

1 and 21

Step-by-step explanation:

-12,  1  , 10 , 21   , 32,   43

43-32 is 11

32-11=21

21-11 is 11

10-11 is 1

Answer:

angleWTR + angleWTU = 180°

Thus they are supplementary.

Option B.

Answer:

y= (3x-1)/2

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

5/50= x/170 multiply 5x170 divide that answer by 50. or bc u know that 5x10 = 50 u could divide 170 by 10 and still get 17

Answer:

17

Step-by-step explanation:

 17 because they write five checks each  50 minutes so it means that every 10 minutes on the check is created incel I went  50 +50+50 =150 And you can't add another 50 so than in 20 minutes to checks can be made and then so I made the conclusion that there can be 17 checks made

hope this helps :)

Answer:

14^3

Step-by-step explanation:

You put the base number to the power of how many numbers are there.

Answer:

14^3 aka 14 to the 3rd power

Step-by-step explanation:

Answer:

the first option is the answer, r = √6

Step-by-step explanation:

[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]

hypotenuse = q = √12

adjacent = p = √6

opposite = r

substitute the values into the hypotenuse formula

[tex]q = \sqrt{r {}^{2} + p {}^{2} } [/tex]

[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]

[tex]( \sqrt{12} ) {}^{2} = r {}^{2} +6[/tex]

[tex]12 = r {}^{2} + 6[/tex]

[tex]12 - 6 = r {}^{2} [/tex]

[tex]6 = r {}^{2} [/tex]

[tex] \sqrt{6} = r[/tex]

[tex]r = \sqrt{6} [/tex]

Answer:

8

Step-by-step explanation:

Given:

Total money Jervane can spend = $20.

Cost of a coffee = $3.

Cost of a donut = $2.

To find: Maximum number of donuts Jervane can buy.

Solution:

Let the number of donuts she can buy be [tex]x[/tex].

She wants to spend no more than $20 in total.

So,

[tex]3+2x\leq 20[/tex]

[tex]\Rightarrow 2x\leqslant 20-3[/tex]

[tex]\Rightarrow 2x\leqslant 17[/tex]

[tex]\Rightarrow x\leqslant \frac{17}{2}[/tex]

[tex]\Rightarrow x\leqslant 8 \frac{1}{2}[/tex]

As the number of donuts can only be a natural number.

Hence, the maximum number of donuts that Jervane can buy are 8.

Answer:

-3(-11+12x)

Step-by-step explanation:

that should be the answer

Answer:

The equation is;

y = 2x^2 -8x + 12

Step-by-step explanation:

The vertex form can be written as;

a(x-h)^2 + k

(h,k) represents the coordinates of the vertex

In this case, we have this as (2,4)

The value of a is positive as the parabola opens up and it is the axis of symmetry

It is the x value that divides the graph into 2

Thus, we have x as = 2

so the equation of the graph will be;

2(x-2)^2 + 4

2(x^2 - 4x + 4) + 4

= 2x^2 -8x + 8 + 4

= 2x^2 -8x + 12

Answer:

25%

Step-by-step explanation:

Given that,

Initial cost of a t-shirt = $30

Final cost of a t-shirt = $37.50

We need to find percent of change. The percentage change in any value is given by :

[tex]\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%[/tex]

Hence, the percentage error is 25%.

The slope is equal to 5/2.

Answer:

9 free-throws

Step-by-step explanation:

75% of 36 = 27
