Last week Juan worked 20.5 hours. This week he works 1.5 times as many hours as he did last. How many hours does Juan work this week?
Answer:
30.75 hours
Step-by-step explanation:
Let
x----> the number of hours worked last week
y ----> the number of hours that Juan work this week
we know that
To find out how many hours does Juan work this week, multiply the number of hours worked last week by 1.5
so
[tex]y=1.5x[/tex]
we have
x=20.5 hours
substitute
[tex]y=1.5(20.5)=30.75\ hours[/tex]
How do I solve this ?

Answer: CD = 8Outliers are always in which quartile(s) of a box and whisker plot?
A. First quartile
B. Second and third quartiles
C. First and fourth quartiles
D. Second and fourth quartiles
Answer:
C. First and fourth quartiles
Step-by-step explanation:
Let's see what outliers are.
If a data value is very far away from the quartiles (either much less than Q1 or much greater than Q3 ), it is sometimes designated an outlier .
Therefore, from the above definition.
Outliers are always in " first and fourth quartiles"
Answer: C. First and fourth quartiles.

The sum of three consecutive odd integers is 951 What are the integers
Answer:
315, 317, and 319
Step-by-step explanation:
So first we have to set the equation up. Since it is odd, we would write
[tex](x-2)+x+(x+2)=951[/tex]
where x is the middle integer. This gets you
[tex]3x=951[/tex]
Solving for x we get
[tex]x=317[/tex]
Since x was the middle, we subtract 2 and add 2 and put them together in ascending order, or 315, 317, and 319.
What is the length of DE
The length of DE is 6 inches.
I can see that from the image, DE is a horizontal line segment that is 6 units long. This is because the x-axis is labeled in units, and DE spans 6 units on the x-axis.
we know that
The triangle XYZ and DEF are similar triangles
therefore
The ratio of their corresponding sides is equal
12/8 = 9/x
x = 8 * 9/12
x = 6 Units.
Therefore the length of DE is 6 inches.

14. A line that passes through the point (5,7) has a slope of 3. Which other point is on that line?
There are no answer choices, so I will just list a few. But first, we need to create the equation.
Plugging in (5,7) into the equation y=mx+b, we can solve for b since all of the other variables are known, with m=3 as the slope.
So, 7=3*5+b
7=15+b
b = -8
y=3x-8 is your equation.
So, you can plug in any value of x you get a certain value of y.
(1,-5), (2,-2), (3,1), (4,4), (5,7), (6,10), (7,13)
Answer:
(6, 10)
Step-by-step explanation:
slope = [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{3}{1}[/tex]
to find another point on the line add 3 to the y-coordinate and add 1 to the x-coordinate
(5, 7) → (5 + 1, 7 + 3) → (6, 10) ← other point on line
continue to do this for other points
(6, 10) → (6 + 1, 10 + 3) → (7, 13)

12x+7<−11 OR 5x−8>40. Solve for the inequality
To solve the inequality 12x+7<−11 OR 5x−8>40, isolate x in each equation. The solutions are x < -1.5 and x > 9.6.
Explanation:To solve for the inequality 12x+7<−11 OR 5x−8>40, we first need to simplify each equation separately i.e isolate x in each separate equation.
For the inequality 12x + 7 < -11: Subtract 7 from both sides, which gives 12x < -18. Then divide by 12 which will yield x < -1.5.
For the inequality 5x - 8 > 40: Add 8 to both sides, which gives 5x > 48. Then dividing both sides by 5, we get x > 9.6.
Our answer is therefore x < -1.5 OR x > 9.6. This means that any x value satisfying either of these conditions will satisfy the original inequality.

To solve the compound inequality 12x + 7 < -11 OR 5x - 8 > 40, solve each inequality separately to find x < -1.5 or x > 9.6. This means x can be any value less than -1.5 or greater than 9.6.
To solve for x in the given compound inequality, we need to handle each inequality separately.
Step-by-Step Solution:
First, solve the inequality 12x + 7 < -11:Subtract 7 from both sides: 12x < -18Divide both sides by 12: x < -1.5Second, solve the inequality 5x - 8 > 40:Add 8 to both sides: 5x > 48Divide both sides by 5: x > 9.6Therefore, the solution to the compound inequality is x < -1.5 OR x > 9.6.
This means x can be any number less than -1.5 or greater than 9.6.

what is the equation of a line that has a slope of 3 and a y-intercept of -3
Answer:
y = 3x-3
Step-by-step explanation:
y = mx+b
m is your slope and b is your y-intercept
plug those numbers in
y = 3x-3
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have m = 3 and b = -3. Substitute:
y = 3x - 3Solve the equation.
-21 = (m/3)
A) m = 7
B) m = -7
C) m = -63
D) m = 63
Answer:
C) m = -63 is your answer
Step-by-step explanation:
Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.
Multiply 3 to both sides
-21 = (m/3)
(-21)(3) = (m/3)(3)
m = (-21)(3)
Combine like terms. Simplify.
m = -21 * 3
m = -63
C) m = -63 is your answer

If two planes intersect, then they intersect in exactly one point. True or false?
Answer: False
A plane is a flat line that extends forever in all directions. Think of a flat piece of paper that does not bend or curve. If you intersect two planes, then they will form a straight line. This line will extend forever both directions. There are infinitely many points on this line of intersection. You can think of a book as a good example: the pages are the planes while the spine is the line of intersection.

( 4 over 4 )x = 4/32 what is the value of x
4 over 4 (4/4) is equal to 1.
The equation can be rewritten as X = 4/32
4/32 can be simplified to 1/8
So you have X = 1/8
Answer:
1/8
Step-by-step explanation:
to simplify 4/32, you just have to see how many times 4 goes into 32, in this case the answer is 8. A good rule of thumb is if the smaller number is on the top of the fraction, you will get a fraction for an answer, so the 4 turns into 1 and the 32 turns into 8.

The location of four buildings are on a coordinate grid are as follows: bank at (3, −3) post office at (−2, −3) dry cleaner at (−2, 6) pizza shop at (3, 6) Liza begins at the bank and then walks to the post office, then to the dry cleaner, and then to the pizza shop. Then she walks to the bank again, where she left her cell phone. The path between each building is a straight line. One unit on the coordinate grid equals 400 yards. What is the total distance Liza walked?
Answer:
11,200 yards
Step-by-step explanation:
First, plot all the points on a graph. Then draw Liza's path. Add them all up and multiply by 400.
28 · 400 = 11,200.
Liza walked 11,200 yards.
My graph is attached. The blue line is Liza's path and each coordinate point is labeled.
I hope this helps u!!
:)
Answer:
11,200 yards.
Step-by-step explanation:
Distance between two points is;
Distance = √(x²+y²)
Distance between Bank and post office = √(5²+0)
= 5
Distance between post office and dry cleaner = √(0+9²)
= 9
Distance between Dry cleaner and pizza shop = √(0+5²)
= 5
Distance between Bank and pizza shop = √(9²-0)
= 9
Total distance = 5+9+5+9
= 28 units
1 unit ⇒ 400 yards
28 units ⇒ (28×400)
⇒ 11,200 Units

Mark bought a concert ticket for $88, then sold it for $121. By what percent did he mark the ticket up?
Answer:
27.27%
Step-by-step explanation:
Formula:
%= 100*(revenue-cost)/ revenue
%= 100* (121-88)/121
By 27.27% the ticket price mark up.
What is Percentage increase?The ratio of the increased value to the original value, multiplied by 100, is the percentage increase formula. It is outlined as a percentage. Anything's value will increase if it is valued more, so will its proportion.
Given:
Mark bought a concert ticket for $88.
Mark sold it for $121.
Change in amount= 121- 88 = $33.
So, the percent increase
= (121- 88) / 88 x 100
= 33/121 x 100
= 3/11 x 100
= 27.27%
Hence, the percent mark up is 27.27%.
