At the same rate, it would take Marisa 6/4 of an hour to paint the entire room. This is a ratio problem, specifically dealing with rates and proportional relationships.
Explanation:Since Marisa painted 1/2 of her room in 3/4 of an hour, to paint the entire room would take double that time. When you double 3/4, you get 6/4. Therefore, at the same rate, Marisa would need 6/4 of an hour to paint the entire room.
This problem is a basic ratio problem related to rates and proportional relationships, common topics in middle school math. The rate in this case is painting speed, half a room per 3/4 of an hour. Thus, when we double the room space to be painted (from half a room to a full room) we should also double the required time.

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?
Above the solid line
Below the solid line
Above the dashed line
Below the dashed line
Answer:
Below the solid line.
Step-by-step explanation:
When you solve for y, you will have a less than or equal to sign, so the shading is below the line.
Answer:
Below the solid line
Step-by-step explanation:
−4y − x ≥ 7
We need to solve for y
Add x to each side
−4y − x +x≥ 7+x
-4y ≥ 7+x
Divide each side by -4. Remember to flip the inequality
−4y/-4 ≤ (7+x)/-4
y ≤ -1/4 x - 7/4
Y is less than or equal to the value so the line is solid (equals sign)
and below ( less than)

Step-by-step explanation:
p=y
by looking at the end of the angles you can tell that P is corresponding to y
ST=FM

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.

The image of point (-6, 2) after a 90° counterclockwise rotation is (-2, -6). This is because a 90° counterclockwise rotation is the same as a 270° clockwise rotation, which is (x, y) → (-y, x).
10.)
The image of point (-9, 3) after reflective it over the line y = x is (3, -9). This is because a reflection over the line y = x is (x, y) → (y, x).

You spent z dollars today. Today, you spent 5.5 times as many dollars as you spent yesterday. Which expression correctly shows how much you spent yesterday?

5.5z

5.5 ÷ z

5.5(1 − z)

z ÷ 5.5

none of the above
Answer:
Z ÷ 5.5
Step-by-step explanation:
The correct expression to show how much was spent yesterday when z dollars were spent today and that amount is 5.5 * the spending of yesterday is z divided by 5.5. The correct answer is option (D) z ÷ 5.5.
If you spent z dollars today and that amount is 5.5 * what you spent yesterday, to find out how much you spent yesterday, you would divide the amount spent today by 5.5. This is because the relationship between what was spent today (z dollars) and what was spent yesterday is multiplicative. Today’s spending (z) is equal to 5.5 * yesterday’s spending, so to find out what you spent yesterday, you would express it as z divided by 5.5.
Thus, the correct answer to the student's question is option (D) z ÷ 5.5.

George’s parents are saving for his college fund. They put $5,000 into an interest bearing account with a compound interest rate of 5.5%. George’s parents want to determine what the balance of his college fund account will be after 15 years. Using the formula a=p(1+r)^t , which is the correct substitution for the formula? a=5000(1+0.055)^15 a=5000(1+0.055)15 a=5000(1+0.055)^5.5 a=(5000+0.055)+1^15
Answer:
a=5000(1+0.055)^15
Step-by-step explanation:
p= amount in present
r=interest
t= period of time
Answer: [tex]a=5000(1+0.055)^{15}[/tex]
Step-by-step explanation:
Given : George’s parents put $5,000 into an interest bearing account with a compound interest rate of 5.5%.
i.e. Principal amount : [tex]p=\$5,000[/tex]
Rate of interest : r=5.5%=0.055
George’s parents want to determine what the balance of his college fund account will be after 15 years. i.e. t= 15
Substitute all the values of p , r at t in the given formula [tex]a=p(1+r)^t[/tex], we get
[tex]a=5000(1+0.055)^{15}[/tex]
Hence, the correct substitution for the formula = [tex]a=5000(1+0.055)^{15}[/tex]
Which are the x-intercepts of the graphed function?
Answer: the correct option is
(B) (-3, 0) and (1, 0).
Step-by-step explanation: We are given to find the x-intercepts of the graphed function.
We know that
x-intercepts of a function are the points on the X-axis through which the graph of the function is crossing.
From the graph, we see that
the curve is crossing the X-axis at the points (-3, 0) and (1, 0).
Therefore, the x-intercepts of the given function are (-3, 0) and (1, 0).
Option (B) is CORRECT.
john is 5 3/4 ft tall how tall is john in inches
John's height from feet to inches is a total of 69 inches.
The question asks how tall John is in inches if he is 5 3/4 feet tall.
To convert feet to inches, you use the fact that one foot equals 12 inches. You need to multiply the whole number of feet by 12 and then add the inches that result from the fractional part.
Step 1: Convert the whole number of feet to inches. John is 5 feet tall, and each foot is 12 inches:
5 feet x 12 inches/foot
= 60 inches
Step 2: Convert 3/4 of a foot to inches. Since there are 12 inches in one foot, you calculate 3/4 of 12:
3/4 x 12 inches
= 9 inches
Step 3: Add the number of inches from the whole feet and the fractional foot together to get John's height in inches:
60 inches + 9 inches = 69 inches
John is 69 inches tall.

The table shows the number of miles driven over time. Express the relationship between distance and time in simplified form as a unit rate.
Time (hours)
4
6
8
10
Distance (miles)
188
282
376
470
Answer:
Relationship between distance and time in simplified form as a unit rate is; [tex]\frac{47}{1}[/tex]
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 3 miles per hour, they are called unit rates.
Unit rate = [tex]\frac{distance}{time}[/tex]
From the given table:
Take any
time = 4 hours and distance= 188 miles
then, by definition of unit rate;
Unit rate = [tex]\frac{188}{4} =\frac{47}{1}[/tex]
Since, this is the constant rate.
Therefore, the relationship between distance and time in simplified form as a unit rate is; [tex]\frac{47}{1}[/tex]
two angles in a triangle mesaure 65 degrees and 75 degrees what is the measure of the third angle of the triangle
Answer:
40°
Step-by-step explanation:
The interior sum of a triangle is 180°. Since we have two known angles we will subtract those values from 180 to obtain our third angle and so:
180°-65°-75°=40°
Answer:
Not sure but i think its 45°.
Step-by-step explanation:
prove the angle sum property of a triangle
Answer:
ANGLE SUM PROPERTY OF A TRIANGLEStep-by-step explanation:
PROPERTY 1 : Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
PROOF : Draw a triangle , then mark each angle as A , B , and C . then take a compass and mark three ark in three sides of a triangle and cut the angles of B and C , then join the two angle B and C with angle A . Then you will find there a COMPLETE ANGLE .
The sum of the measures of angles of triangle is equal 180°.
Look at the picture.
We have the congruent corresponding angles and the vertical angles.

74.362 to the nearest tenth
Answer:
73.4
Step-by-step explanation:
When they ask for the nearest tenth you check the hundreth, it its 5 or ore than you increase the tenth
The number 74.362 would round down to 74.4
For Rounding some number to a specific value is making its value simpler mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.
We need to round 74.362 to the nearest tenth,
To round 74.362 to the nearest tenth, we need to look at the digit in the hundredth place, which is 2. Since 2 is less than 5, we round down and keep 4.
Therefore, rounding 74.362 to the nearest tenth gives us 74.4.
