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

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

can someone help me do 1 and 2?? Thank you so much !!!!!!!
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°

Step-by-step explanation:
Decimal multiplication problem:
250 x 0.72 = 180
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
Hope this helps :-)
How many different outcomes are possible when 3 coins are flipped at once?
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.

Step-by-step explanation:
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.

Answer:
22.50
Step-by-step explanation:
Hat = $18
Austin - 6 letters
0.75 x 6 = 4.5
Letters cost $4.50

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
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.

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

Spinner Results
Color Frequency

Blue 3
Green 2
Yellow 2
Purple 6
Based on these results, express the probability that the next spin will land on blue as a fraction in simplest form.
Step-by-step explanation:
so, we had
4+3+2+2+6 = 17 experiments
I assume the spinner has 5 equality sized fields with different colors.
so, normally we would assume that in average each color has the same probability : 1/5 (desired results over totally possible results).
the experiments with the actual spinner give us now observational data and probabilities.
after all, a spinner (as a die, or a roulette wheel, or ...) can have slightly different probabilities for the individual outcomes based on design and manufacturing.
so, based on these results we see the actual probabilities like this
red 4/17
blue 3/17
green 2/17
yellow 2/17
purple 6/17
so, the observed probability shows us a probability of blue in the next spin to be 3/17.
please note, that after that next (18th) spin all the observed probabilities have to be updated depending on the actual result.
so, if the result of spin 18 is indeed blue, the probabilities for spin 19 would change to
red 4/18
blue 4/18
green 2/18
yellow 2/18
purple 6/18
