Giardo is using the model below to solve the equation 3×+1 = 4×+(-4) which step could be adjusted so that Gerardo final step results in a positive x value
Answer:
The answer is B. In step one he should have added 3 negative x-tiles to both sides.
See attachment for complete question.
Answer:
The correct option is B.
In step one he should have added 3 negative x-tiles to both sides.
Step-by-step explanation:
Given the equation
3x + 1 = 4x + (-4)
Adding 3 negative x tiles, we have
3x + 1 + (-3x) = 4x + (-4) + (-3x)
1 = x - 4
x = 1 + 4 = 5
Miles has a piece of paper that is 1/4 of a large circle.He cuts the paper into five equal parts from the center point of the circle. What is the angel measure of each part?
Answer:
18°
Step-by-step explanation:
First, we find the angle of the large piece of paper that is 1/4 of a circle.
The angle in a circle is 360°. The angle in 1/4 of a circle is:
1/4 * 360 = 90°
He cuts the paper into five equal parts from the center point of the circle. That means the angle was divided into 5 parts:
1/5 * 90 = 18°
Each part has an angle of 18°,
Answer: it's 18
Step-by-step explanation: 18 is the answer hope this helps

A triangle has two sides with the lengths 8m and 15 m. Which of the following lengths could represent the length of the third side? Choose all that apply. 1. 23m 2. 4m 3. 10m 4. 14m 5. 7m
Answer:
3. 10m
4. 14m
Step-by-step explanation:
Angle inequality rule: A triangle can only form if it's 2 shortest sides add up to have MORE length than it's longer side.
1. 23 m
2. 4m
3. 10m
4. 14m
5. 7m
1 doesn't follow the angle inequality rule.
2 doesn't follow the angle inequality rule.
3 can be the third side.
4 can be the third side
5 doesn't follow the angle inequality rule.
QUESTION 5 of 10: You are considering selling your home. You consult with an agent who gives you the asking prices of five homes (comps)
in your area: $165,000, $188,000, $175,000, $150,000 and $400,000. The $400,000 is an outlier so you will not include it in your evaluation. In
determining a reasonable asking price, what is the mean of the four remaining comps?
a) $188,000
b) $215,000
Oc) $169,500
d) $175,000
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500

13-196/4
13-49
-13
Answer & Step-by-step explanation:
(5 + 1)² - (11 + 3²) ÷ 4
Following the rules of order of operation, the first thing we have to do is the operations in the parentheses ().
(6)² - (11 + 3²) ÷ 4
Next, solve for your exponents.
36 - (11 + 9) ÷ 4
Next, do the operations in the parentheses ().
36 - (20) ÷ 4
Now, divide -20 by 4.
36 - 5
Subtract 5 from 36.
31
So, your final answer to this equation is 31.
find the value of root 121 + 3 over root 125
The value of the given expression √121 + ∛125 would be 16 which is determined by the square root and cube root properties.
What is Prime Factorization?Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.
The expression below which is given in the question
⇒ √121 + ∛125
Here 11×11 = 121 and 5×5×5 = 125
⇒ √(11×11) + ∛(5×5×5)
By the square root and cube root properties to get
⇒ 11 + 5
Apply the addition operation,
⇒ 16
Thus, the value of the given expression √121 + ∛125 would be 16.

w(x) = 2x^3+ 3x; Find w(3)
Answer:
63
Step-by-step explanation:
w(x) = 2x³ + 3x
Put x as 3.
w(3) = 2(3)³ + 3(3)
Solve for the power.
w(3) = 2(27) + 3(3)
Multiply the terms.
w(3) = 54 + 9
Add both the terms.
w(3) = 63
Answer:

find the coordinates of H' after a reflection across the parallel lines; first across y = -2 and then across y = 2. Answer in form (a,b). Part 7a
Answer: H' = (-4, 4)
Step-by-step explanation:
H = (-4, -4)
reflect across y = -2:
H is 2 units below y = -2 so when reflected it will be 2 units above y = -2
--> the x-coordinate doesn't change the new y-coordinate is: 0
H' = (-4, 0)
reflect across y = 2:
H' is 2 units below y = 2 so when reflected it will be 2 units above y = 2
--> the x-coordinate doesn't change the new y-coordinate is: 4
H'' = (-4, 4)
Which pair of triangles is congruent?
Answer:

Answer:
100πcm².None of the options is correctStep-by-step explanation:
Total surface area of a cone [tex]S[/tex] = [tex]\pi r^{2}+\pi rl\\[/tex]
Since the diagram is half of a cone, its surface area will be [tex]S = \frac{\pi r^{2} +\pi rl}{2}[/tex]
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m

solve for p
Answer:
[tex] \boxed{p = 4} [/tex]
Step-by-step explanation:
[tex] = > {p}^{2} = 16 \\ \\ = > {p}^{ \cancel{2}} = {4}^{ \cancel{2}} \\ \\ = > p = 4 \\ \\ \\ OR \\ \\ \\ = > {p}^{2} = 16 \\ \\ = > {p}^{2} = {4}^{2} \\ \\ = > p = \sqrt{ {4}^{2} } \\ \\ = > p = {4}^{ \cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ = > p = 4 [/tex]
Using the given equation, we know that the square root of p = 16.
Because of this, we also know that the square root of 16 will equal p.
[tex]\sqrt{16} = 4[/tex]
Therefore, p is equal to 4, or p = [tex]\sqrt{16}[/tex].

Melissa and Jane are planting trees. Melissa plants 10 trees in 1 hour. Jane plants 17 tree in 2 hours.
Enter an equation that can be used to find the number of hours t, takes Melissa and jane to plant 111 trees together
Answer:
6 hours
Step-by-step explanation:
Let both of them plan for t hours to plant 111 trees n t hours
Melissa can plants 10 trees in 1 hour
in t hours she can plant 10 t trees
Jane plants 17 tree in 2 hours
in one hour Jane can plant 17/2 trees
in t hours she can plant (17/2)t trees.
Total trees planted by both of them in t hours in terms of t will be
10t + (17/2)t
= (10t*2 + 17t)/2
= (20t + 17t)/2
= 37t/2
but it is given that they planted 111 trees together
so 37t/2 should be equal to 111
37t/2 = 111
=> 37t = 111*2 = 222
=> t = 222/37 = 6.
Thus, it takes 6 hours for both of them to plant 111 trees together.
b) The ratio of boys to girls in a school is 12:25. If there are 120 boys.
(i) how many girls are in the school?
(ii) what is the total number of boys and girls in the school?
Answer:
250 girls in the school and 370 students all total
Step-by-step explanation:
250 girls are in the school and 390 total students in the school.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
The ratio of boys to girls in a school is 12:25
Let, No. of boys in the school = 12x
No. of girls in the school = 25x
Total students in the school = 12x+25x = 39x
Given, there are 120 boys
So, 12x = 120
x = 10
No. of girls in the school = 25x = 25(10)
No. of girls in the school = 250
Total students in the school = 39x = 39(10)
Total students in the school = 390
Hence, 250 girls are in the school and 390 total students in the school.
