Answer:

B. Multiply by 2, add 1

explanation:

23× 2 = 46 + 1 = 47

47 × 2 = 94 + 1 = 95

95 × 2 = 190 + 1 = 191

Answer:

90

Step-by-step explanation:

a right angle is always 90 degrees

Answer:

14

Step-by-step explanation:

1/7*X=2

X=2/(1/7)

X=2*7

X=14

Answer:

x = 10

y = -4

Step-by-step explanation:

[tex]\ -4(2 - 1.2x ) = 40\\\ -8 + 4.8x = 40\\\ 4.8x = 40+8\\\ 4.8x = 48\\x = \frac{48}{4.8} = \frac{48 \times 10}{48} = 10[/tex]

[tex]9 = 6y + 33\\6y = 9 -33\\6y = -24\\y = -4[/tex]

Answer:

x=  -9       y= -4

Step-by-step explanation:

Step 1:

  2x-3y=-6

+ -2x-2y=26

_____________

         -5y=20

Step 2:

Get y by itself by dividing -5 on both sides

20/-5=-4

Therefore, y= -4

Step 3:

Plug -4 into the y for the first equation to get the number for x

2x-3(-4)=-6

2x+12=-6

2x= -18

x= -9

Answer:

[tex]f(x) = (0.85)^x[/tex]

Step-by-step explanation:

Exponential amount of decay:

The equation for an amount that decays exponentially has the following format:

[tex]A(x) = A(0)(1 - r)^x[/tex]

In which r is the decay rate, as a decimal.

Decrease by 15%

This means that [tex]r = 0.15[/tex]. So

[tex]f(x) = (1 - r)^x = (1 - 0.15)^x = (0.85)^x[/tex]

So

[tex]f(x) = (0.85)^x[/tex]

Answer:

The answer is 20s+10h=500

Step-by-step explanation:

The reason is because 20 times 20=400 and then 10 times 10= 100 then you add those together and get $500

Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

Answer:

930 in^2

Step-by-step explanation:

Area of a parallelogram is Base x Height.

so, 30 x 31 = 930.

Answer: 930 in ^2

Step-by-step explanation:

Area is width x height.

Width = 30

Height = 31

30x31 = 930

Answer:

A)-19,15,-9,-1,9

Step-by-step explanation:

that's the answer when I compute it

===================================================

Explanation:

If we plug in x = -2, then we get,

y = x^2 + 7x - 9

y = (-2)^2 + 7(-2) - 9

y = 4 - 14 - 9

y = -10 - 9

y = -19

So x = -2 leads to y = -19. The answer is between A and D.

---------

If you repeat those steps for x = -1, then you should get y = -15

Then x = 0 leads to y = -9

x = 1 leads to y = -1

Finally, x = 2 leads to y = 9

The outputs we get are: -19, -15, -9, -1, 9 which is choice A

Choice D is fairly close, but we won't have a second copy of -15, and  we don't have an output of -19.

Answer:

A

Step-by-step explanation:

The first graph shows a dot on .5 and the recipes calls for half a cup of sugar.

Answer:

Step-by-step explanation:

[tex]f=\frac{1}{2}s[/tex] is the graph of a straight line with a slope of 1/2. This implies that for every cup of sugar, 1/2 a cup of flour is needed. This also implies what the graph looks like in a coordinate plane. Slope is defined as rise over run, or y over x, so if our slope is 1 over 2, from the origin we go up 1 unit and over 2 units along the length of the whole line. The only graph that displays this slope is graph A.

Answer:

m = 18

Step-by-step explanation:

10/15 = m/12

Cross multiply using the butterfly method.

15m = 10*12

15m = 120

Divide both sides by 15.

m = 8

Answer:

3/4

Step-by-step explanation:

Maria practiced for her piano recital each day for three days. the first day she practiced for 3/4 hour, the second day she practiced for 1 1/2 hours, and the third day she practiced for 2 1/4 hours. by how much did she increase the time she practiced each day?

the increase in hours practiced can be determined by calculating the difference between the hours practiced on the second and first day

[tex]1\frac{1}{2} - \frac{3}{4}[/tex]

[tex]1\frac{2 - 3}{4}[/tex]         the lowest common multiple that can divide 2 and 4 is 4.

[tex]\frac{6-3}{4}[/tex]          if 2 is subtracted from 3, the answer  would be negative. So,                                              borrow 1 from the whole number. the value of this borrowed one would be equal to 4 which is the LCM. Add 4 to 2. this gives 6

Step 2: Evaluate

Answer:

20

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

21^2 + b^2 = 29^2

441+b^2 =841

Subtract 441 from each side

441 +b^2 -441 = 841-441

b^2 = 400

Take the square root of each side

sqrt(b^2) = sqrt(400)

b =20
