Answer:

B (5t + 15 ≤ 140) is correct

Step-by-step explanation:

Because since each table (t) seats 5 people, you'd represent that as 5t (5 seats per table).

Since there is one extra table that seats 15 people, you'd represent that as 15.

Lastly, those two last steps added together should have to be less than or equal to (≤) 140 (the amount of people allowed in the building).

Answer:

1. 3/4 2. -1/3

Step-by-step explanation:

#1:

Given rise/run, the rise is 3, and the run, is 4, so... 3/4

#2:

Given rise/run, the rise is 2, and the run is 6, so... you get 2/6 = 1/3. However, don't forget that the slope is negative, so it'll be -1/3.

Answer:

3. 3/4

4. -1/3

Step-by-step explanation:

Since the rise and run formula is slope = (y1-y2)/(x1-x2),

3. (2 - (-1) ) / (2- (-2) ) = 3/4

4. (-1- (-3) ) / (-2 - (-4) ) = -2/6 = -1/3

First, find the area of the bigger rectangle by multiplying the length and width.

24*21=504

Then find the area of the smaller rectangle the same way

3*6=18

then add them to get the total area

504+18=522

Answer:

m = -1

Step-by-step explanation:

As we move from (-5, 6) to (-2, 3), x (the 'run') increases by 3 and y (the 'rise) decreases by 3.  Hence the gradient, or slope, of this line segment is

m = rise / run = -3/3, or m = -1

Answer:

306.80

Step-by-step explanation:

250 + 4% = 260

260 + 18% = 306.80

Total amount paid by Jamal is $305

Step-by-step explanation:

Given that;

Cost of meal = $250

Local sale tax rate = 4%

Percentage of tip left by Jamal = 18%

Find:

Total amount paid by Jamal

Computation:

Total tax paid by Jamal = 250 × 4%

Total tax paid by Jamal = $10

Total amount of tip left by Jamal = 250 × 18%

Total amount of tip left by Jamal = $45

Total amount paid by Jamal = Cost of meal + Total tax paid by Jamal + Total amount of tip left by Jamal

Total amount paid by Jamal = 10 + 45 + 250

Total amount paid by Jamal = $305

Answer:

28pi, 10pi

Step-by-step explanation:

So, lets go over a few things.

What is circumference?

Circumference is the permiteter of a circle.

The formula for it is 2*r*pi.

Now, lets go over what radius and diamater is.

Diamater is the distance between the two opposite sides of the circle.

The radius is half of the diamater, and is the distance between one side of the circle and the middle.

Problem #1:

The distance from the middle to the side of the circle is 14.

This will be the radius, not the diamater.

Lets plug this into the formula:

2*14*pi

=

28*pi

=

28pi

This is your answer.

Problem #2

The distance from the two opposite sides of the circle is 10.

So the radius will be half of this, being 5.

Now lets plug this in:

2*5*pi

=

10*pi

=

10pi

This is your answer.

Hope this helps!

Answer:

Future population in 19 years = 3,254,580 people (Approx.)

Step-by-step explanation:

Given:

Current population of city = 900,000

Growth rate of population = 7%

Number of year = 19

Find:

Future population in 19 years

Computation:

A = P[1+r]ⁿ

Future population = Current population[1+g]ⁿ

Future population in 19 years = 900,000[1+7%]¹⁹

Future population in 19 years = 900,000[1+0.07]¹⁹

Future population in 19 years = 900,000[1.07]¹⁹

Future population in 19 years = 900,000[3.6162]

Future population in 19 years = 3,254,580

Future population in 19 years = 3,254,580 people (Approx.)

Answer:

Equation:y = 1/2x .  or x = 2y

Constant = 2

Step-by-step explanation:

Input y = output x

the first input/output says that when inputed 2, the number 1 is outputted.

Similarly, when 5 is inputted, 2.5 is the output.

1/2 = 2.5/5

That means that y = 1/2 x

or x = 2y

Answer:

x = -4, -2

Step-by-step explanation:

Given equation is,

x² + 6x + 8 = 0

Let the equation to be graphed is,

y = x² + 6x + 8

y = x² + 2(3x) + 9 - 1

y = x² + 2(3x) + 3² - 1

y = (x + 3)² - 1

Table for the Input-output values  

x           -6          -4            -3            -2            -1            0            

y            8           0            -1              0             3            8      

Now we can plot these points on the graph as attached.

Since, this graph is intersecting x-axis at x = -4, -2

Therefore, solutions of the given equation will be x = -4, -2

Answer:

pumpkin because it got the most sold

Answer:

9

Step-by-step explanation:

Knowing that

pumpkin = 6

Total =

​chocolate cupcakes 2 + ​pistachio cupcakes ​ 1 + ​banana cupcakes ​ 5 +​pumpkin cupcakes ​ 6

Thus, 2 + 1 + 5 + 6 = 14

Cross multiply

[tex]\frac{6}{14}=\frac{x}{21}[/tex]

6 * 21 = 126

126/14 = 9

Hence, next 21 cupcakes sold that will be pumpkin cupcakes will 9 pumpkin cupcake

Answer:

The test statistic for Norah's test is [tex]t = -2[/tex]

Step-by-step explanation:

Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.

This means that at the null hypothesis we test if the sample mean is 500 ml, that is:

[tex]H_0: \mu = 500[/tex]

At the alternate hypothesis, we test if it is differente than 500 ml, that is:

[tex]H_a: \mu \neq 500[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

500 is tested at the null hypothesis:

This means that [tex]\mu = 500[/tex]

She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.

This means that [tex]n = 16, X = 497, s = 6[/tex]

Calculate the test statistic for Norah's test.

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{497 - 500}{\frac{6}{\sqrt{16}}}[/tex]

[tex]t = -2[/tex]

The test statistic for Norah's test is [tex]t = -2[/tex]
