4:8 and 32:64 are equal ratios. True or False
Answer:
True
Step-by-step explanation:
this is because when reduced to their most simple terms they are the same so:
4:8 divide both sides by 4 and get: 1:2
32:64 divide both sides by 32 and get: 1:2 as well

Solve the inequality. | 2x + 3 | < 7
please show all the work
Answer:
[tex]-5<x<2[/tex]
Step-by-step explanation:
We have the inequality:
[tex]|2x+3|<7[/tex]
Use the definition of absolute value:
[tex](2x+3)<7\text{ or } -(2x+3)<7[/tex]
Let's evaluate each case individually.
Case 1)
We have:
[tex]2x+3<7[/tex]
Subtract 3 from both sides:
[tex]2x<4[/tex]
Divide both sides by 2:
[tex]x<2\\[/tex]
Case 2)
We have:
[tex]-(2x+3)<7[/tex]
Divide both sides by -1. Since we're dividing by a negative, flip our sign:
[tex]2x+3<-7[/tex]
Subtract 3 from both sides:
[tex]2x<-10[/tex]
Divide both sides by 2:
[tex]x<-5[/tex]
So, our solutions are, from least to greatest:
[tex]\{x|-5, 2\}[/tex]
We can see that our inequality is a greater than.
Remember, when dealing with absolute value:
When our sign is greater than (or equal to), our solution is an "or" inequality with our solutions being all values less than our lesser solution or all values greater than our greater solution.
When our sign is less than (or equal to), our solution is an "and" inequality with our solution being between our two solutions.
Since our inequality is a less than, our solution is all the values between our lesser solution and our greater solution.
Our lesser solution is -5. Our greater solution is 2.
So, the solution to the inequality is all values between -5 and 2. As a compound inequality, this is:
[tex]-5<x<2[/tex]
And we're done!

Step-by-step explanation:
A square room in Denise's house measures 15 feet by 15 feet. Find the length of the diagonal of the room, rounded to the nearest tenth
The length of the diagonal of the room is approximately 21.2 feet when rounded to the nearest tenth.
Given information:
A square room in Denise's house measures 15 feet by 15 feet.
Since the room is square, the diagonal forms the hypotenuse of a right triangle whose legs are the sides of the square.
Each side of the square measures 15 feet, so we have:
d² = 15² + 15²
Simplifying:
d² = 2(15²)
d² = 2(225)
d² = 450
Taking the square root of both sides:
d ≈ 21.2

Find the distance between the two points in simplest radical form.
(8, – 7) and (1, -1)
Answer:
The distance between the two points is [tex]\sqrt{85}[/tex] units
Step-by-step explanation:
Let us revise the rule of the distance between two point [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex]
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
∵ We need to find the distance between the two points (8, -7) and (1, -1)
→ Let [tex]x_{1}[/tex] = 8 and [tex]x_{2}[/tex] = 1
→ Let [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = -1
→ Substitute their values in the rule above
∴ [tex]d=\sqrt{(1-8)^{2}+(-1--7)^{2}}[/tex]
∴ [tex]d=\sqrt{(-7)^{2}+(-1+7)^{2}}[/tex]
∴ [tex]d=\sqrt{49+36}[/tex]
∴ [tex]d=\sqrt{85}[/tex]
→ Simplify the radical
∵ 85 = 5 × 17
→ Both of them are prime numbers
∴ The simplest form of [tex]\sqrt{85}[/tex] is [tex]\sqrt{85}[/tex]
∴ The distance between the two points is [tex]\sqrt{85}[/tex] units

simplify for this. 22 + (3x3 - 4x4)
Answer:15
Step-by-step explanation: 1st multiple what’s in the parenthesis (3*3= 9 & 4*4= 16
Next write it out 22+(9-16)
Then you subtract 9 from 16 since it’s in parenthesis So it’s 22+(-7) and since you are adding a negative and a positive together you will have to subtract and keep the sign of the larger number so the answer is 15 since u needed to subtract but 22 is the larger number making it positive answer
4.) Trapezoids ABCD and EFGH are congruent. What is the length of side FG?
a. 9 m
b. 12 m
C. 15 m
Answer:
C. 15m
Step-by-step explanation:
if ABCD and EFGH are congruent that means that they are equivalent to each other. If side FG is the base of that trapizoid, and side CD is the base with the measurement of 15m, then we are left to believe that side FG is 15m

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equation can be used to find the maximum and minimum wait times at a bus stop?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Let absolute variation in the wait time at the bus stop = v
Variation = ±3 minutes
Average bus run through the city = 15 minutes
Hence, the minimum and maximum run values due to the variation can be modeled as:
|variation - average run| = ±3
|v - 15| = ±3
minimum : v = - 3 +. 15 = 12 minutes
Maximum : v = 3 + 15 = 18 minutes

Answer:
x = -5
Step-by-step explanation:
Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.
This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).
So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.
On the right side we are given 9 for AD, and 18 for DC.
9/18 = 0.5
This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:
If AD/DC = 0.5, then BE/EC will also = 0.5
BE = x+23
EC = x+41
Therefore:
[tex]\frac{x+23}{x+41} = 0.5[/tex]
Now we can solve by multiplying both sides by x+41 to eliminate the fraction:
[tex]x+23=0.5(x+41)[/tex]
Now we multiply out the brackets and move the terms to different sides:
[tex]x+23=0.5x+20.5[/tex]
[tex]0.5x = -2.5[/tex]
[tex]x = -5[/tex]
And if we substitute the -5 into the equations:
-5+23 = 18
-5 + 41 = 36
We will see that -5 does indeed give us the same ratio between the lengths:
18/36 = 0.5

A survey o 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at at night. Tara claims that 33:55, 48:88 and 20:65 are possible ratios from this data. Jim claims that 35:100, 405:100 and 200:100 are possible ratios from the data who is correct? Explain
Answer:
Jim is correct.
Step-by-step explanation:
Given that:
Total people = 100
People who exercise in morning = 35
People who exercise in the afternoon= 45
People who exercise in the evening = 20
Ratio claimed by Tara = 33:55, 48:88, and 20:65
Ratio claimed by Jim = 35:100, 45:100, and 20:100
To find:
who is correct ?
Solution:
Looking at the ratio claimed by Tara, the ratio are number which are not known to us.
Therefore, the ratio claimed by Tara can not be correct.
Now, looking at the ratio claimed by Jim:
35:100, 45:100, and 20:100
35 is the number of people who exercise in morning.
45 is the number of people who exercise in evening.
20 is the number of people who exercise in night.
and 100 is the total number of people.
Therefore, this ratio represents the "Part-to-whole" ratio.
So, Jim is correct.

You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/4 cup of walnuts for the oatmeal and 7/8 cup of walnuts for the salad. You have a 1/8 -cup scoop. Complete the descriptions of two different ways to find how many scoops of walnuts you will need. Enter all non-whole number answers as mixed numbers in simplest form.
Answer:
13 scoops
Step-by-step explanation:
Description 1
Step 1
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
Total cups of walnuts needed for both salad and oatmeal =
3/4 cups + 7/8 cups
(3/4 + 7/8)
(6 + 7/8)
= 13/8 cups of walnuts
= 1 5/8 cups of walnuts
Step 2
You have a 1/8 -cup scoop
The number of cup scoops of walnuts need is calculated as
1 5/8 cups ÷ 1/8 cup scoop
= 13/8 ÷ 1/8
= 13/8 × 8/1
= 13 scoops
Therefore, 13 scoops of walnuts is needed.
Description 2
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
1/8 cup scoop
Therefore,
(3/4 + 7/8) ÷ 1/8
=(13/8) ÷ 1/8
= 13 scoops of walnuts are needed
