Answer:
The other part is 27 in. long
Step-by-step explanation:
1 ft is 12 in
2 ft are 24 in
4 ft are 48 in
48 in - 21 in = 27 in
Answer:
Part A
Green rope = 4 ft
As 1 ft = 12 in
Then 4 ft = 4 × 12 in = 48 in
Antonia cuts the green rope into 2 pieces. One of the pieces is 21 in long. To find the length of the unknown piece, subtract the length of the known piece from the total length:
length of unknown piece = 48 - 21
= 27 in
Part B
Blue rope = 2 yd
1 yd = 36 in
Therefore, 2 yd = 2 × 36 = 72 in
Antonia wants to cut the rope into MORE than 3 pieces, and all the pieces need to be of equal length. As the length of the rope is an even number of inches, Antonia could first cut the rope in half, so she would have 2 pieces each of 36 in in length. Then she could cut both of those lengths in half, so she would have 4 pieces each of 18 in in length.
A car has a displacement of 220 kilometers to the north in 3.5 hours. What is its velocity in kilometers per hour?
Answer:
62.8km/hr
Step-by-step explanation:
Given parameters:
Displacement = 220km due north
Time taken = 3.5hrs
Unknown:
Velocity in km/hr = ?
Solution:
Velocity is the rate of displacement per unit of time. This physical quantity is a vector which has both magnitude and directional attributes.
So, mathematically;
Velocity = [tex]\frac{displacement}{time taken}[/tex]
Insert the parameters and solve;
Velocity = [tex]\frac{220}{3.5}[/tex] = 62.8km/hr
Colin was using the back of his book to check his homework answers. The answer that he had on his paper was −13 − (15 + 58). The correct answer, located in the back of the book, was −13 −15 + 58. Was Colin correct? Justify your response
Answer: No. Collin was wrong.
Step-by-step explanation:
From the question, we are informed that the answer that Collin had on his paper was −13 − (15 + 58) and the correct answer, located in the back of the book, was −13 −15 + 58.
Collin is wrong because he didn't take into cognisance the effect of minus on the bracket. Here, −13 − (15 + 58) will be equal to -13 -15 -18. This is because minus multiplied by plus equals to minus. He shouldn't have put the numbers in the bracket.

Because what you want to do is add 260 to 182 then subtract from 587. I hope that helped! :)
Why do people at school think I'm not very smart when I get A's in every class? I don't really raise my hand a lot in class...... maybe that's why? I also am kind of quiet around some people but I don't act d/umb and whenever I do speak to some of those people, it's always intelligent. I'm the new kid, and at my old school, I was always called smart..... so why do they call me du/mb?
Answer:
Honestly, I feel you. I've been there. Being the new kid not also brings problems related to your character, but to your feelings. I totally think you're smarter than all your other classmates! :D. Keep being yourself and never let them bring you down. If you fall down and don't feel like getting back up, remember this message!

Answer:
They may not know very much about you and assume things about you based on things they see and perceive that are separate from the grades that you get and/or they think you aren't intelligent on something to do with your emotions/behavior and/or someone or some amount of people have developed something against you, these are just potential situations.
Step-by-step explanation:
Regardless of what the reason is, move forward with what you do and meet people who enjoy your company. Those who treat you badly are not worth your time. Best of luck!

Answer:
106 degrees
Step-by-step explanation:
1. Supplementary angles add up to 180. So subtract 74 from 180 to find the measure of angle C.
2. The full square isn't visible to answer.
1. m∠C = 106°
If angle A and angle C are supplementary, then the sum of their measures is 180°. Thus:
m∠A + m∠C = 180°
74° + m∠C = 180°
m∠C = 180° - 74°
m∠C = 106°

Can you find the AREA of this shape please, thank you!
Answer:
40.81125m²
Step-by-step explanation:
Hello!
Step 1: Rectangle
We can find the area of the rectangle by multiplying the base by the height.
A = base * heightA = 5m * 2mA = 10m²Step 2: Area small semicircles
If we add the two semicircles, we can see that it's actually 1 whole circle.
So we can simply find the area of the whole circle.
radius = 1/2 * diameter
A = πr²A = (3.14)(1m)²A = 3.14m²Step 3: Large semicircle
Now for the last part, the large semi-circle at the top.
Since it's half a circle, we can manipulate the formula by finding half of it.
A = (1/2)πr²A = (1/2)(3.14)(2.5m)²A = (1/2)19.625m²A = 9.8125Step 4: Total Area
Total area = 10m² + 3.14m² + 9.8125m²
= 40.81125m²

Austin wants to buy a new hat and to get his name embroidered onto it. The hat costs $18 and each letter costs $.75. How much will Austin have to pay to buy the hat and get his name put on it? (enter your answer as a decimal without dollar sign)
Answer:
22.50
Step-by-step explanation:
Hat = $18
Austin - 6 letters
0.75 x 6 = 4.5
Letters cost $4.50
18 + 4.5 = 22.5
He'll have to pay 22.50 dollars.

The freshman class is selling candy bars to raise money. They purchased 3100 candy bars and paid a delivery fee of $35. The total cost, including the delivery fee, was $1430. What was the cost of each candy bar?
Answer:
$0.45
Step-by-step explanation:
To answer this question, we first have to subtract the delivery fee from the total cost:
1430 - 35 = 1395
Now, we divide this number by the total amount of candy bars:
1395 / 3100 = 0.45
So, each candy bar costs $0.45
Hope this helps :)
Each candy bar would be 45 cents

anybody know this answer?
Answer:
y = -4/5x + 3
Step-by-step explanation:
Chose any two points on the line:
(5, -2)
(-5, 6)
Slope = (y2 - y1) / (x2 - x1)
6 -(-2) / -5 - 5
8 / -10
-4/5
Equation:
y = mx + b
Plug in x and y using any coords and then plug in m (the slope):
-2 = -4/5 * 5 + b
-2 = -20/4 + b
-2 = -5 + b
Add 5 on both sides:
3 = b
Now our equation is:
y = -4/5x + 3

1. Wendy wants to find the width, AB, of a river. She walks along the edge of the river 300 ft and marks point C. Then she walks 80 ft further and marks point D. She turns 90° and walks until her location, point A, and point C are collinear. She marks point E at this location, as shown.
(a) Can Wendy conclude that ΔABC and ΔEDC are similar? Why or why not?
(b) Suppose DE = 50 ft. Calculate the width of the river, AB. Show all your work.
Answer:
It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.
How to solve the triangle?It should be noted that the triangles are similar because the three internal angles are equal.
In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent.
The width of the river will be:
300/80 = AB/50
AB = (300 × 50)/80
AB = 187.50 feet.

Can u help me please I would appreciate it
Answer:
A 13°
Step-by-step explanation:
We need to know the measure of angle LMN.
The angle measures of a triangle add up to 180°.
MLN=15°
LNM=180-28=152° (LNM and MNP are supplementary, meaning they add up to 180°)
LMN=15+152=167 180-167=13

Use the graph of the equation to solve: -2x - 5 = 3
Answer:
x = -4
Step-by-step explanation:
-2x - 5 = 3
Add 5 to both sides
-2x - 5 + 5 = 3 + 5
Simplify
-2x = 8
Divide both sides by -2
-2x/-2 = 8/-2
Simplify
x = -4

Kaitha wanted to buy a laptop. she saved 1/3 of the cost of the laptop in the first month. In the second month, she saved $125 less than what she saved in the first month. she saved the remaining $525 in the third month. how much did the laptop cost.
Answer:
It costed $1200
Step-by-step explanation:
First Month Saved 1/3 of total cost
Second Month (1/3 of total cost) - 125
Third Month 525
525-125= 1/3 of total (If she saved the same amount the second month as the first month, then she's already saved 2/3 of the money)
400 = 1/3 of total cost
3X400=1200
