Please answer these 2 questions first to get them right gets brainliest :'(

Answer:

3 to the power of 7 is 2,187.

Step-by-step explanation:

3x3x3x3x3x3x3=2,187

Work Shown:

Divide the two amounts, smaller over bigger, to get

231/2100 = 0.11

Then move the decimal point over two spots to the right to get to 11%

Note how 11% of 2100 = 0.11*2100 = 231.

Answer:

The slope of the line is 3.

Step-by-step explanation:

Given function;

x(t) = -t² + 5t

y(t) = 3t, when t = 2

[tex]\frac{dx}{dt} = -2t + 5[/tex]

[tex]\frac{dy}{dt} = 3[/tex]

[tex]\frac{dy}{dx}= \frac{dy}{dt} \ \times \ \frac{1}{\frac{dx}{dt} } \\\\\frac{dy}{dx}= 3 \ \times \frac{1}{-2t + 5} \\\\\frac{dy}{dx}= \frac{3}{-2t + 5}[/tex]

t = 2

[tex]Then, \ \frac{dy}{dx}= \frac{3}{-2(2) + 5} \\\\\frac{dy}{dx}= \frac{3}{-4 + 5} \\\\\frac{dy}{dx}= \frac{3}{1} \\\\\frac{dy}{dx}= 3[/tex]

Therefore, the slope of the line is 3.

Answer:

Left 2 and down 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Choose a random fraction less than 1. I will choose 1/4.

1/6 ÷ 1/4 = 1/6 × 4/1 = 4/6 = 2/3

2/3 > 1/6 so this example supports his claim.

Now chose a fraction greater than 1. I will choose 4/3

1/6 ÷ 4/3 = 1/6 * 3/4 = 3/24

3/24 < 1/6 so this contradicts his claim

Answer:

x=3 , y=-1

Step-by-step explanation:

9x-13=6x-4

9x-6x=13-4

3x=9

x=3

9y+16=4y+11

9y-4y=11-16

5y=-5

y=-1

Answer:

-28    +    -1    =    -29

     -14    +    -2    =    -16

     -7    +    -4    =    -11

     -4    +    -7    =    -11

     -2    +    -14    =    -16

     -1    +    -28    =    -29

     1    +    28    =    29

     2    +    14    =    16

     4    +    7    =    11

     7    +    4    =    11

     14    +    2    =    16

     28    +    1    =    29

Answer:

S (1 , 0)

T (7 , 1)

Step-by-step explanation:

If QRST is a parallelogram, P is the mid point of segment QS and segment RT.

Basic formula for mid-point of segment: ((x1+x2)/2 , (y1+y2)/2)

T (x₁ , y₁)    S (x₂ , y₂)   P (2 , 3)    Q (3 , 6)   R (-3 , 5)

2 = (x₁ + (-3))/2         x₁ = 7

3 = (y₁ + 5)/2            y₁ = 1

T (7 , 1)

2 = (x₂ + 3))/2         x₂ = 1

3 = (y₂ + 6)/2           y₂ = 0

S (1 , 0)

Answer:

B. 4/3

Step-by-step explanation:

[tex] \frac{ {4}^{ - 3} . {3}^{4} . {4}^{2} }{ {3}^{5} . {4}^{ - 2} } \\ \\ = \frac{ {4}^{ - 3} . {4}^{2 + 2} }{ {3}^{5 - 4}} \\ \\ = \frac{ {4}^{ - 3} . {4}^{4} }{ {3}^{1}} \\ \\ = \frac{ {4}^{4 - 3} }{ {3}^{1}} \\ \\ = \frac{ {4}^{1} }{ {3}^{1}} \\ \\ = \frac{4}{3} [/tex]

Answer:

B. 4/3

Step-by-step explanation:

(4^-3 . 3^4 . 4^2)/(3^5 . 4^-2)

4^-3 . 4^2/ 4^-2 . 3^4/ 3^5

4^(-3+2-(-2)) . 3^(4-5)

4^1 . 3^-1

4 . 1/3 = 4/3

Answer:

I guess there are 6 small pieces but dont know how long they are sry

Answer:

12 small piece of ribbon, each 3/2 inches long

Step-by-step explanation:

one 18" long ribbon divided into 3 equal pieces will produce three 6 inch ribbons

three 6" ribbons, each one cut in half (or divided by 2), equals 12 pieces

each one  being 18/12 inches long; which reduces to 3/2

Answer:

38 candies.

Step-by-step explanation:

Given the following data;

Total number of candy = 874

Total number of children = 23

Since we know that they are all sharing it equally, each child would get;

Each child = 874/23

Each child = 38 candies.

Answer:

(1, 3)

Step-by-step explanation:

If quadrilateral ABCD is reflected across the line y = x, then the x- and y-coordinates get reversed. Since the coordinates of point D are (3, 1), then the coordinates of point D' are (1, 3).

Answer:

its a its aaaa itsssssssssssssssssssssss aaaaaaaa sorry im just in a good mood

Step-by-step explanation:

Answer:

1) 4

2) 2

3) 5

4) 8

Step-by-step explanation:

All you have to do in this question is to substitute what they are telling you.

First blank:

They told us that m is 0 so if we plug that into the equation we can get s.

[tex]2m+4s=16\\2(0)+4s=16\\4s=16\\s=4[/tex]

In this one if m is 0, s will have to be 4.

Second blank:

They told us that s is 3 so if we plug in that into the equation we can get m.

[tex]2m+4s=16\\2m+4(3)=16\\2m+12=16\\2m=4\\m=2[/tex]

In this one if s is 3, m will have to be 2.

Third blank:

They told us that m is -2 so if we plug that into the equation we can get s.

[tex]2m+4s=16\\2(-2)+4s=16\\-4+4s=16\\4s=20\\s=5[/tex]

In this one if m is -2, s will be 5.

Fourth blank:

They told us that s is 0 so if we plug into the equation we can get m.

[tex]2m+4s=16\\2m+4(0)=16\\2m=16\\m=8[/tex]

In this one if s is 0, then m will be 8.

Answer:-20

Step-by-step explanation:

First divide 60 by 3 as you would regularly.

Your answer should be 20

Make sure to remember when multiplying with integers:

negative x negative = positive

positive x positive = positive

negative x positive = negative

positive x negative = negative

Make sure to remember when dividing with integers:

positive / positive = positive

negative / negative = positive

positive / negative = negative

negative / positive = negative

Because this question is a "positive / negative" your answer would be negative. Therefore your answer is -20

I hope this helps! :)

Step-by-step explanation:

S=smaller number; L=larger number=3S

.

4S+5L=133

4S+5(3S)=133

4S+15S=133

19S=133

S=7 ANSWER 1: The smaller number is 7.

.

L=3S=3(7)=21 ANSWER 2: The larger number is 21.

.

CHECK:

4S+5L=133

4(7)+5(21)=133

28+105=133

133=133
