Answer:
844,000
Step-by-step explanation
Last three numbers are the hundreds, that's what you round when doing thousands. If it is higher than 500, then raise it to the next thousand, if not then keep it the same. In this case, 590>500, so I will round up to 844,000.
9+3x-5x=4x-3x please solve with multi step variable on both sides
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
9 + 3x - 5x = 4x - 3x
Step 2: Solve for x
Combine like terms: 9 - 2x = xAdd 2x to both sides: 9 = 3xDivide both sides by 3: x = 3Step 3: Check
Plug in x to verify it's a solution.
9 + 3(3) - 5(3) = 4(3) - 3(3)
9 + 9 - 15 = 12 - 9
18 - 15 = 3
3 = 3

Marsha’s scores on seven tests were: 82, 78, 77, 93, 85, 91, and 86. What does she need to score on her next test to have an 86 average?
Answer:
The score of her next test is 96
Step-by-step explanation:
If there is a set of data with x terms, then the average is the sum of their values divided by x
Average = sum of values of the x terms ÷ x
We will use this rule to solve the question
∵ Marsha's scores on 7 test were 82, 78, 77, 93, 85, 91, 86
→ Find her total scores on the seven tests
∴ Her total scores = 82 + 78 + 77 + 93 + 85 + 91 + 86 = 592
∴ Her total scores on the 7 tests is 592
∵ Her average score on the 8 test is 86
→ Use the rule of the average to find her total score in the 8 test
∵ 86 = total scores ÷ 8
→ Multiply both sides by 8
∴ 86 × 8 = total scores × 8 ÷ 8
∴ 688 = total scores
∴ Her total scores on the 8 tests is 688
∵ Her total scores on the 7 test = 592
∵ Her total scores on the 8 test = 688
→ The difference between both totals is the score of her next test
∴ The score of her next test = 688 - 592 = 96
∴ The score of her next test is 96
Is this relation a function?
yes
no
Answer:
no

the scores on a collegiate mathematics readiness assessment are approximately normally distributed with a mean of 680 and a standard deviation of 120. determine the percentage of scores between 690 and 900, to the nearest percent.
43.36% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.
To determine the percentage of scores between 690 and 900, we need to calculate the area under the normal distribution curve between these two values.
First, we need to standardize the scores using the formula z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation.
For the score 690:
z1 = (690 - 680) / 120 = 0.0833
For the score 900:
z2 = (900 - 680) / 120 = 1.8333
Next, we need to find the area between these two standardized scores. We can use a standard normal distribution table or a statistical calculator to find the corresponding probabilities.
From the standard normal distribution table, we find that the area to the left of z1 is approximately 0.5328 and the area to the left of z2 is approximately 0.9664.
To find the area between z1 and z2, we subtract the smaller area from the larger area:
Area = 0.9664 - 0.5328 = 0.4336
Finally, we convert the area to a percentage by multiplying by 100:
Percentage = 0.4336 * 100 ≈ 43.36%
Therefore, approximately 43% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.

Explain how you can use SSS, SAS, ASA, OR AAS with the definition of congruence to prove the statement true
Answer:
D, AAS.
Step-by-step explanation:
So basically the a's and s' mean angle and side. this means that if there is a line on both of the triangles on one side this means that those sides of the triangle are congruent. this is the same case with the angles. if you were to have one congruent side inbetween two congruent angles, you would use ASA, which stands for angle side angle, to prove that the triangles are congruent. some more examples are:
side, side, angle =SSA.
angle, angle side = AAS. (the problem in question)
hope this helps :)
The answer is option C)
What is the AAS congruence rule?If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. This is the AAS congruence rule.
Given here in ΔVTY and ΔWYX
VY = WX , ∠VYT = ∠WXY and ∠VTY = ∠WYX
Therefore, by AAS congruence rule , we get ΔVTY≅ ΔWYX
Accordingly, by the property of congruence of triangles we get
TV = YW
Hence, option C) ΔVTY≅ ΔWYX by AAS, so TV = YW by def of ≅

The angle x in the diagram is 98 degrees.
How to find the angles in parallel lines?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angle, alternate exterior angles, vertically opposite angles, same side interior angles etc.
Therefore, let's find the angle of x using the angle relationships as follows:
The size of the angle x can be found as follows:
82 + x = 180(same side interior angles)
Same side interior angles are supplementary.
Hence,
82 + x = 180
x = 180 - 82
x = 98 degrees

Item 11 1/1 1/1 Math (Numeric): Erin has a total of 18 coins worth $2.05. All of the coins are either nickels, dimes, or quarters. If the number of nickels is twice the number of quarters, how many of each kind of coin does she have? Nickels: 1 10 ✓ Dimes: 2 3 Quarters: 3 Item 9 1/1 Math (Numeric): Convert 4/116 to rectangular coordinates. 1 -1.75 +2 3.60 ✔ 1/1
In the first item, Erin has a total of 18 coins with a combined value of $2.05. The coins consist of nickels, dimes, and quarters. It is stated that the number of nickels is twice the number of quarters, and we are asked to determine the quantities of each coin.
Let's assign variables to represent the number of each coin. Let N be the number of nickels, D be the number of dimes, and Q be the number of quarters. We have three equations based on the given information:
N + D + Q = 18 (the total number of coins is 18)
5N + 10D + 25Q = 205 (the total value of the coins is $2.05)
N = 2Q (the number of nickels is twice the number of quarters)
To solve this system of equations, we can substitute N = 2Q into the first two equations. Substituting N with 2Q in equation 1 gives us:
2Q + D + Q = 18
3Q + D = 18
Substituting N with 2Q in equation 2 gives us:
5(2Q) + 10D + 25Q = 205
10Q + 10D + 25Q = 205
35Q + 10D = 205
Now we have a system of two equations with two variables. By solving these equations simultaneously, we can determine the values of Q, D, and N.

Looking in figure;
5x = 100° {vertically opposite angle}
x = 100°/5
Therefore, X = 20°.
2.)
Looking through figure;
3x + 39° = 90°{The symbol in figure is 90°}
3x = 90°-39°

Answer:
The angles are congruent, not supplementary. x = 20The angles are complementary, not supplementary. x = 17Step-by-step explanation:
1. The equation should be 5x = 100, because the marked angles are congruent.
Then, dividing by 5 gives ...
x = 100/5
x = 20
__
2. The angles have a sum of 90°, not 180°. The correct equation is ...
3x +39 = 90
x + 13 = 30 . . . . divide by 3*
x = 17 . . . . . . . . subtract 13
_____
* Sometimes when the terms of the equation have the coefficient of x as a common factor, I like to divide by that first. It makes all of the numbers smaller, so more comfortable for me to deal with. The usual method would be to subtract 39 before doing the division. You get the same answer either way.

At top cruising speed, a mako shark can swim 4 kilometers in 1/10 hour. A blue whale can swim 5 kilometers in 1/4 an hour which animal swims faster at a top cruising speed? How much faster? Show your work.
Answer: Mako shark
Step-by-step explanation:
We will calculate the speed of the sharks to know which is faster.
A mako shark can swim 4 kilometers in 1/10 hour.
Speed = Distance/Time
= 4/(1/10)
= 40km/hour
A blue whale can swim 5 kilometers in 1/4 an hour.
This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 5km/hour. It's faster by 35km.
= 40km - 5km
= 35km
