Step-by-step explanation:

Answer:

Step-by-step explanation:

In order to find who is more efficient at planting carrots, we want to put both ratios in terms of the same amount of time.

For simplicity, lets see how many carrots each can make in 1 hour.

[tex]Janet:\\9ft \: in \: 15 \:minutes[/tex]

[tex]\frac{9ft}{15min} = \frac{xft}{60min}\\x = \frac{60*9}{15} = 36[/tex]

Janet can plant 36 feet of carrots in one hour

[tex]Amy:\\\frac{17ft}{30min} = \frac{xft}{60min}\\x = \frac{17*60}{30} = 34[/tex]

Amy can plant 34 feet of carrots in one hour

So, Janet can plant carrots more quickly

Step-by-step explanation:

A decimal is a number that represents a fractional part of a whole. For example, the decimal 0.25 represents 25/100. Numbers with decimals are not integers because an integer is defined as a whole number with no fractional part.

Step 1 = the opposite of a sum is the sum of its opposites

Step 2= Subtraction as adding the opposite

Step 3=Any order, Any grouping

Step 4= Combine like terms

Step 5= Combine like terms

I would seek other's advice for these --^

All you need to do for the bottom one is multiply.

-4 times 3a

-4 x 3 = -12

-4 times 3a = -12a

-4 times -2b

-4 x -2 = 8

-x- = +

-4 x -2 b = 8b

-4 x 4c

-4 x 4 = -16

-4 x 4c = -16c

Answer:2

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

First look at the big overall triangle.

It has a right angle and another angle of 44; therefore the missing angle is (since the sum of angles inside a triangle is 180)

180 - 90 - 44 = missing angle

missing angle (top) = 46; now the angle of a straight line is 180 and they give you 56° which  has a supplementary angle of 180 - 56 = 124°.

Now we know that the triangle that include the x has angles 46° (missing top angle), and supplementary angle of 124°.  Therefore

x = 180 - 46 - 124

x = 10

Answer:

B) All Real Numbers greater than or equal to 0 and less than or equal to 9

Answer:

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.

Step-by-step explanation:

The unit rates for both machines need to be calculated first.

The unit rate will be calculated as:

[tex]Unit\ rate = \frac{Area\ covered}{Time}[/tex]

For Machine A:

Area Covered = 5/8

Time = 1/4

The unit rate will be:

[tex]U_A = \frac{\frac{5}{8} }{\frac{1}{4} } \\Using\ rule => \frac{\frac{a}{b} }{\frac{c}{d} } = \frac{a}{b} * \frac{d}{c}\\=\frac{5}{8} * 4 \\= \frac{5}{2} = 2.5\ square\ feet\ per\ hour[/tex]

For Machine B:

Area Covered = 2/3

Time = 1/5

[tex]U_B = \frac{\frac{2}{3}}{\frac{1}{5}}\\= \frac{2}{3} * \frac{5}\\= \frac{10}{3}\\= 3.33...\ square\ feet\ per\ hour[/tex]

As it can be seen that unit rate for Machine B is greater than Unit Rate of Machine A.

Hence,

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.

75/1000

.075

So the answer is .75

Answer:

Q1 d, Q2 c, Q3 d

Step-by-step explanation:

Q1

g(x)=-3x+1

g(x)=16 means that

-3x+1=16 subtract 1 from both sides

-3x=16-1 combine like terms and divide both sides by -3

x=-15/3=-5

Q2

g(x)=3x²+4x-1

g(2) means that x=2 so substitute

g(2)=3*2²+4*2-1=12+8-1=19

Q3

domain are the x values

range are the y values

Answer:

Step-by-step explanation:

Step one:

we are required to find the slope of the given data points

A(4,6) B(5,8)

hence the x and y values correspond to

x1=4

y1=6

x2=5

y2=8

Step two:

Required is the slope which is

slope= y2-y1/x2-x1

Slope=8-6/5-4

Slope= 2/1

Hence the slope of the ordered pair is 2

Answer:

Answer:

you have to fisrt solve the equation of the buttonm part the find the common number between 5 to 8

Answer:

First multiple 10 x 4. Then multiple 3.14 x 25 because the radius is 5 and the area of the circle would be 3.14 x 25 then add your answer from that to 40. so add 40 plus the answer from 3.14 x 25.  

Answer:

1

Step-by-step explanation:

When x is 0, y is 1 and the y intercept is the y value when x is 0.

Answer:

Step-by-step explanation:

The y intercept always lies on the y axis on the graph, meaning x is 0. So your y intercept would be 1
