Answer:
[tex]36\frac{3}{4} miles[/tex] and [tex]45 miles[/tex] respectively
Step-by-step explanation:
There are a few ways to solve this
First we find the speed of the car, which is the distance divided by time [tex]speed=\frac{distance}{time}[/tex] now distance is [tex]1\frac{3}{4} =\frac{7}{4} miles[/tex] and the time is [tex]2\frac{1}{3} =\frac{7}{3} minutes[/tex] Then [tex]speed=\frac{7}{4} /\frac{7}{3}=\frac{7}{4} *\frac{3}{7}=\frac{3}{4} miles/minute[/tex] Using this speed, we just find the distance using different time valuesrewriting the formula so the distance is the subject gives [tex]distance=speed*time[/tex] So for time as 49 minutes we have [tex]distance=(\frac{3}{4}miles/minute)*(49minutes)=36\frac{3}{4} miles[/tex] Then for time as 1 hour which is 60 minutes we have [tex]distance=(\frac{3}{4}miles/minute)*(60minutes)=45miles[/tex]Help with these 3 please

Option 1. (8 ÷ 3) - 2³x 17 = 33
Option 2. (8 + 3) - 2³ x 17 = 33
Option3. (8 x 3) - 2³+ 17 = 33
Option4. (8-3) x 2³+ 17 = 33
Answer:
it will be option 3 if isnt pls tell me and I'll work if out
(8 x 3) - 2³+ 17 = 33 is the true statement and so Option 3 is the correct answer.

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

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?
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

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

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.
D. No; Machine A and Machine B make 30.75 ounces in 10 minutes. 30.75 < 72, so there will not be enough popcorn.

A local restaurant serves breakfast. They use 124 cups of pancake mix every hour. It takes 114 cups of mix to make one pancake. The pancakes are all equal in size.
About how many pancakes can the restaurant make in two hours?
A 99 pancakes
B 198 pancakes
C 251 pancakes
D 310 pancakes
198 pancakes can the restaurant make in two hours.
What is Equation?Two or more expressions with an equal sign is called as Equation.
The restaurant can make 199 pancakes in two hours.
Given: Total number of cups of pancake mix used in 1 hour = 124
Mix required for each pancake 1 1/4=5/4.
Number of cups of pancake mix used in 2 hours = 2 x 124 = 248
Number of pancakes made = (Number of cups of pancake mix used in 2 hours ) ÷ (Mix required for each pancake )
=248÷5/4
=248×4/5
=198.4
Hence 198 pancakes can the restaurant make in two hours.

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
Answer:
11.8 feetStep-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)

Which ordered pair is a solution to the linear inequality given below?
3x + 4y > 20
(-5,1)
(0,-3)
(-4,2)
(2,7)
Answer:
(2, 7 )
Step-by-step explanation:
Substitute the coordinates of each pair into the left side of the inequality and compare the result to the right side.
(- 5, 1 )
- 15 + 4 = - 11 < 20 ← not a solution
(0, - 3)
0 - 12 = - 12 < 20 ← not a solution
(- 4, 2 )
- 12 + 8 = - 4 < 20 ← not a solution
(2, 7 )
6 + 28 = 34 > 20 ← solution
The ordered pair which is correct for the given inequality will be equal to (2, 7). Hence, option D is correct.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
The given inequality is,
3x + 4y > 20
For point (-5, 1)
3(-5) + 4(1) > 20
-11 > 20, this is incorrect.
For point (0, -3)
