Answer:
[tex]x = \frac{33}{5} [/tex]
or
[tex]x = 6 \frac{3}{5} [/tex]
or
[tex]x = 6.6[/tex]
Step by Step:
Step 1: Rewrite the equation (I used x instead of k.)
[tex] \frac{x}{4} = \frac{33}{20} [/tex]
Step 2: Make x a loner by moving the 4 to the right side.
[tex]4 \times \frac{x}{4} = \frac{33}{20} \times 4 [/tex]
Step 3: Cancel multiplied terms on the left, multiply numbers on the right.
[tex]x = \frac{165}{100} [/tex]
Step 4: Simplify.
[tex] x = \frac{33}{5} [/tex]

Answer:
Store B offers the better buy. The difference in Unit cost is 5 cents or $0.05
Step-by-step explanation:
First find the costs per tuna. In Store A: 8 cans cost $7.20. To find the cost of 1 can you have to do $7.20/8 which is 90 cents or $0.90In store B; 6 cans cost $5.10. To find the cost of 1 can do $5.10/6 which is 85 cents or $0.85.Therefore store B is cheaper, and to find the difference cost: Do the larger cost minus the smaller: 90 cents-85 cents= 5 cents or $0.05 as the difference cost
I almost cry please help. Q:Two signs are on a street. One blinks every 10 s and the other every 6 s. How many times per minute do they blink together? (The answer is twice and why please show how you find out the answer is twice)
Answer:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 80,
So twice
Step-by-step explanation:
What else do you need but that ^
Answer:
Step-by-step explanation:
if one blinks every 10 seconds it means that it blinks 6 times in one minute
60/10=6
the other one blinks every 6 seconds
60/6=10 blinks ten times
first one blinks: 10,20,30,40,50,60
second one blinks:6,12,18,24,30,36,42,48,54,60
is like finding GCM

hence- twice
How would the line on the graph below change if the slope and the y-
intercept were multiplied by 3?
Answer:
A.) The line would shift up and have a y-intercept at 12 and the slope would be -9
Step-by-step explanation:
The y-intercept is where the graph intersects the y-axis. This graph intersects at 4, so if it was multiplied by 3, the new y-intercept would be 12.

10x + 2y = 18
-10x + 7y = 18

O (-4.0), (0.2)
pls help
Answer:
Option 2: none of these
Step-by-step explanation:
-x +2y= 4
x-intercept occurs at y=0.
When y=0,
-x +2(0)= 4
-x= 4
x= -4
Thus, x-intercept is (-4,0).
y-intercept occurs at x=0.
When x=0,
0 +2y= 4
2y= 4
y= 4 ÷2
y= 2
Thus, y-intercept is (0,2).
*When writing coordinates, the x and y coordinates are separated by a comma in the bracket. If the 3rd option is a comma instead of a dot (which could instead denote a multiplication sign), it would be the correct option.

we can simplify like terms

If 1 inch is 500 miles, then 4 inches is how many miles?
Answer:
2,000 miles
Step-by-step explanation:
We are given:
[tex]1 inch=500 miles[/tex]
This can be rewritten as:
[tex]\frac{500 miles}{1inch}[/tex]
This is representative of a unit rate, as we have a [tex]1[/tex] in the denominator. To calculate the number of miles in [tex]4[/tex] inches, simply multiply the unit rate by [tex]4[/tex]:
[tex]\frac{500 miles}{1inch}*4=[/tex]
[tex]\frac{2000 miles}{4 inches}[/tex]
This can rewritten as:
[tex]4inches=2000miles[/tex]
Therefore, there are 2,000 miles in 4 inches.
-
We can check our solution by simplifying the fraction [tex]\frac{2000 miles}{4 inches}[/tex] by dividing both [tex]2000[/tex] and [tex]4[/tex] by [tex]4[/tex] to see if we achieve the unit rate:
[tex]\frac{500 miles}{1 inch}[/tex]
Since this is in fact the unit rate, our solution is correct!

Find the length of the radius of the circle.
A)
2 inches
B
B)
3 inches
)
6 inches
D)
8.5 inches
Answer:
C) 6 inches
Step-by-step explanation:
(√72)² = x² + x²
72 = 2x²
72/2 = x²
36 = x²
√36 = √x²
6 = x
x = 6 inches
Answer:
By Pythagoras theorem, we get
[tex] {x}^{2} + {x}^{2} = {( \sqrt{72}) }^{2} \\ 2 {x}^{2} = 72 \\ {x}^{2} = 36 \\ \boxed{x = 6}[/tex]
C) 6 inches is the right answer.In one study on the effect of argan oil on wrinkles, 125 subjects who acknowledged being long-time argan oil users had their wrinkles compared with those of 125 people who had never used argan oil. In a second study, 75 subjects were chosen randomly to use argan oil and 75 were chosen to use a placebo. Identify the types of studies performed. (4 points)
Answer: The first study was an observational study whereas the second was a controlled experiment.
Step-by-step explanation:
A study that record the characteristics of a population by studying individuals in a sample, but does not manipulate variables of interest is known as an operational study. Like in the first study only effects have been noted.
A controlled experiment is an experiment where the variable of interest is directly manipulated by a scientist, in order to test a single variable at a time.
Like in the second study, the subjects were under the control of the experimenter, to test the effect of oil.
The first study was an observational study whereas the second was a controlled experiment.

Henry is purchasing a number of magnets. He wants some idea of how many he can buy. On a coordinate plane, the points (3, 1), (6, 2), and (12, 4) are plotted. Using equivalent ratios, which statements are true about the cost per magnet? Check all that apply. The cost of 2 magnets is $1. The cost of 9 magnets is $3. The cost of 10 magnets is $3. The cost of 4 magnets is $2. The cost of 6 magnets is $2. The cost of 3 magnets is $1. Mark this and return
Step 1: Find the slope
Every 3 magnets that you buy, you need to pay 1 more dollar. Therefore, if you have 9 magnets, the cost will be 3 dollars. Also, if you have 6 magnets, the cost will be 2 dollars. Finally, if you have 3 magnets, the cost will be 1 dollar. So... the correct options are Options B, E, F
Answer options: B,E,F

A group of friends ate a meal in a restaurant, and the cost of their bill is m. Which expression represents the total amount that they'll pay if they tip 20%?
Question 4 options:
A)
1.2 + m
B)
0.2m
C)
1.2m
D)
0.2 + m
The expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
It is given that a group of friends ate a meal in a restaurant, and the cost of their bill is m.
We need to find the expression that represents the total amount that they'll pay if they tip 20%.
So we know that,
20% = 0.20
The cost of their bill = m.
The total amount they'll pay including tip = 0.2 + m
Therefore, the expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.
