Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags?


A. Yes; Machine A and Machine B make 77.5 ounces in 10 minutes. 77.5 > 72, so there will be enough popcorn.


B. Yes; Machine A and Machine B make 87.5 ounces in 10 minutes. 87.5 > 72, so there will be enough popcorn.



C. No; Machine A and Machine B make 67.5 ounces in 10 minutes. 67.5 < 72, so there will not be enough popcorn.

Answer:

-1/3

Step-by-step explanation:

m = (y2-y1) / (x2-x1)

m = (-2-(-1)) / (3-0)

m = (-2+1) / 3

m = -1/3

Answer:

A 12 foot ladder is leaning up against a wall. If the angel made between the ladder and the ground is 80 degrees. How far up can the ladder reach the wall? Round to the nearest tenth of a foot

Answers

Answer:

11.8 feet

Step-by-step explanation:

Given

Length of the ladder = 12foot

angle of elevation = 80 degrees

Required

Height of the wall (opposite side)

The set up will form a right angled triangle where

length of the ladder is the hypotenuse

height of the wall is opposite;

Using SOH, CAH, TOA trig identity

According to SOH

sin 80 = opp/hyp

sin80 = opp/12

opp = 12sin80

opp = 11.82 feet

Hence the height of the wall is 11.8feet (to the nearest tenth)

1. What absolute value expression can be written to determine the distance between 63 feet above sea level and 48 feet below sea level?​

Answers

Given:

The distance between 63 feet above sea level and 48 feet below sea level.

To find:

The ​absolute value expression for the given situation.

Solution:

We have,

Distance above the sea level = 63 feet

Distance below the sea level = -48 feet

Here, negative sign represents the distance in below the sea level.

So, absolute value expression that can be written to determine the distance between 63 feet above sea level and 48 feet below sea level is

[tex]Distance=|63-(-48)|[/tex]

[tex]Distance=|63+48|[/tex]

[tex]Distance=|111|[/tex]

[tex]Distance=111[/tex]

Therefore, the required absolute expression is [tex]|63-(-48)|[/tex] and distance is 111 feet.

Which polynomial function could be represented by the graph below?

Answers

Answer:

Option B: f(x) = 2x2 + 2x – 4

Step-by-step explanation:

f(x)=x²-4x-5 is the polynomial function of the given graph.

What is Polynomial?

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

We need to find the polynomial of the given graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

When x=0, then y should be -5.

This can be satisfied by f(x)=x²-4x-5 and  f(x)=-x²-4x-5

Now let us find the value of y when x is 2.

When x is 2 the value of y should be -9 by the given graph

f(x)=x²-4x-5

=4-8-5

=-9

Hence, f(x)=x²-4x-5 is the polynomial function of the given graph.

You are a sales clerk in a clothing store. You receive a salary of $320 per week plus a 5% commission on all sales. Write an equation to represent your weekly salary. (Let y equal the weekly salary and x equal the amount of sales.) What are the slope and y-intercept of your equation?

Answers

Answer:

slope: 0.05

y-intercept: 320

Step-by-step explanation:

y is the total weekly salary and x is the sales

there is a constant salary of $320, which will be the constant in the equation.

y = mx + b

y = mx + 320

we know there is a 5% commission on all sale, which we can convert to the fraction 0.05.

y = .05x + 320

Now we can see that the slope is .05 and the y-intercept is 320

|10+4x|<14 how do you solve this?

Answers

Answer:

-6 < x < 1

Step-by-step explanation:

-14 < 10 + 4x < 14

Subtract 10 from both sides

-24 < 4x < 4

Divide both sides by 4

-6 < x < 1

Answer: - 6 < x < 1

|10 + 4x| < 14

⇔ -14 < 10 + 4x < 14

⇔ -14 - 10 < 4x < 14 - 10

⇔ - 24 < 4x < 4

⇔ -24/4 < x < 4/4

What is the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0)?



Enter your answer in the box.

Answers

Answer:

The equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  [tex]x-2y=0[/tex]

Step-by-step explanation:

Given the line

[tex]x-2y=-4[/tex]

[tex]x+4 = 2y[/tex]

[tex]y=\left(\frac{1}{2}\right)x+2[/tex]

[tex]m_1=\frac{1}{2}[/tex]

so, the slope of the line parallel to the given line would have

the same slope as  [tex]\frac{1}{2}=m[/tex], and passed through the point (0, 0).

Therefore, the equation of the required line is given by

[tex]y = mx+b[/tex]

[tex]y=\left(\frac{1}{2}\right)x+0[/tex]

[tex]y=\left(\frac{1}{2}\right)x[/tex]

[tex]2y=x[/tex]

[tex]x-2y=0[/tex]

Therefore,  the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  [tex]x-2y=0[/tex]
