Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.
umm please help me it is confusing
Answer: x = 24 & x = 96
Step-by-step explanation:
Answer: Every option given is a solution
Any value larger than 18 is a solution. So we can say x > 18.
============================================================
Explanation:
To isolate x, we multiply both sides by 6 like so
3 < x/6
3*6 < x
18 < x
x > 18
In the last step, I swapped the left and right sides. This swap meant that I had to flip the inequality sign as well. Saying x > 18 means we can pick anything larger than 18 to have it as a solution. Something like x = 5 is too small, but values like x = 24 and x = 96 will work. In fact, all of the answer choices given are larger than 18. So you'll check each answer box.
---------
As a way to confirm a potential answer, we plug it back into the original inequality. Let's say we wanted to check x = 90
So,
3 < x/6
3 < 90/6 ... replace every x with 90
3 < 15
The last inequality is true, because 3 is indeed smaller than 15. Therefore, the original inequality is true when x = 90. We confirm that x = 90 is a solution.
The steps to confirm x = 114, x = 96, and x = 24 will follow the same idea. I'll let you do those confirmations.

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Researchers for a textile company carried out an experiment comparing the longevity of two new fabric blends.
They carried out a series of usage tests, known as double rubs, on 100 pieces of each type of material. These scales are used for this type of testing.
Fabric Grade Number of Double Rubs
(in thousands)
Heavy duty
Medium duty
Light duty
Delicate duty
After performing the tests on each fabric, researchers found that on average, fabric A lasted through 7,900 double rubs and fabric B lasted through 9,200 double rubs.
The marketing department wants to advertise that both fabrics are tested and approved for medium-duty use.
Which statements are true about this situation?
The sales department can refer to fabric A as a medium-duty fabric.
The sales department can refer to fabric B as a medium-duty fabric.
Fabric A is a more durable fabric because it has a lower double rub rating than fabric B.
Fabric B is a more durable fabric because it has a higher double rub rating than fabric A.
Neither fabric meets the requirements of a medium-duty fabric.
Fabric B is a more durable fabric because it has a higher double rub rating than fabric A.
We have given that,

temporary. How many
temporary employees are
there?
Answer:
18
Step-by-step explanation:
Step 1: Convert 25% to a fraction
[tex]\frac{25}{100}[/tex]
Simplify
[tex]\frac{1}{4}[/tex]
Step 2: Convert 72 to a fraction
[tex]72 = \frac{72}{1}[/tex]
Step 3: Set it up
[tex]\frac{1}{4}\times \frac{72}{1}[/tex]
Step 4: Cross divide
[tex]72 \div 4 = 18[/tex]

You and your friends go to the state fair. It costs $6 to get into the fair
and $2 each time you go on a ride. Consider the relationship between
number of rides and total cost.
Model the equation to show the linear relationship.
Answer:
[tex]let \: number \: of \: rides \: be \: \: n \\ let \: cost \: be \: \: c \\ n \: \alpha \: c \\ n = kc \\ k \: is \: a \: costant \: of \: proportionality \\ when \: n = 1. \: \: c = 2 \\ 1 = (k \times 2) \\ k = \frac{1}{2} \\ therefore : \\ n = 0.5c[/tex]
Answer:
[tex]\huge\boxed{\sf x = 6 + 2y}[/tex]
Step-by-step explanation:
Let the total cost be x and number of rides be y
It costs $2 on each ride. So, the rides' cost will be:
=> Number of rides * One rides' cost
=> y * 2
=> 2 y
So, The total cost will be:
Total cost = Entrance cost + Rides' cost
Total cost = $6 + $2(Number of rides)
x = 6 + 2y

What is the surface area of this composite solid?
Use 11.3 meters for the slant height of the triangular prism.
Enter your answer in the box.
__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?
Answer:
As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.
Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.
Subtract the 2 hours from 10am:
= 10 - 2
= 8am
Subtract the 15 minutes from 45:
= 45 - 15
= 30
Put that together:
= 8:30 am
They left their house at 8:30 am using this scenario.
A simple impact crater on the moon has a diameter of 15 kilometers. A complex impact crater has
a radius of 30 kilometers. How much greater is the circumference of the complex impact crater than
the simple impact craters?
Answer:
141.3 km
Step-by-step explanation:
First crater has the radius (that is, half the diameter) of 7.5 km; the circumference of this crater is C = 2(pi)r, or 2(3.14)(7.5 km) = 47.1 km;
Second crater radius is C = 2(pi)(30 km) = 188.4 km
The circumference of the complex (larger) impact crater is
(188.4 - 47.1) km greater than the circumference of the simple (smaller) crater:
141.3 km
