Step-by-step explanation:
You have to separate the triangles into two, where you can compare short over long. DC = AB, so DC is the long side in the smaller triangle and AC is the shorter side. DC is similar to AC, and DE is similar to AB. Short over long side formula gives you [tex]\frac{x}{9} =\frac{4}{x}[/tex].
Cross multiply to get [tex]x^2=36[/tex]
Square root on both sides to get [tex]x=6[/tex]

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?
Answers
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!

Use the graph of the equation to solve: -2x - 5 = 3
Answers
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
Spinner Results
Color Frequency
Red 4
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.
Answers
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

can someone help me do 1 and 2?? Thank you so much !!!!!!!
Answers
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°
sorry number 1 lang asan kase yung figure sa number 2
Can u help me please I would appreciate it
Answers
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

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
Answers
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.

A city's bus system has a red-line and a blue-line. Both a red-line bus and a blue-line bus are currently at the City Hall Station. If a red-line bus arrives at the City Hall Station every 12 minutes and a blue-line bus arrives at the City Hall Station every 10 minutes, after how many minutes will the two buses next arrive at the City Hall Station at the same time?
Answers
Answer:
5.45minutesStep-by-step explanation:
Given that the arrival time of the redline bus= 12minutes
arrival rate = 1/12 arrival per minutes
arrival time of the blueline bus= 10minutes
arrival rate = 1/10 arrival per minutes
the combined arrival rate is given by the expression
let redline be A
and blueline be B
and let the combines arrival rate be x
A+B/(A*B)=1/x
1/12+1/0=1/x
12+10/12*10=1/x
22/120=1/x
x=120/22
x=5.45minutes
Can you find the AREA of this shape please, thank you!
Answers
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

A car has a displacement of 220 kilometers to the north in 3.5 hours. What is its velocity in kilometers per hour?
Answers
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

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.
Answers
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
