if MN=NQ and MQ=QR=RP, calculate for x
Answer:
C. 18°Step-by-step explanation:
Refer to attached diagramGiven MN = NQ MQ = QR = RPNMR = 3xQMR = xTo findValue of xSolutionMN = NQ ⇒ ∠MRN = ∠QMN = 3x+x = 4xMQ = QR ⇒ ∠MRQ = ∠QMR = xRQP is exterior angle of ΔMQR ⇒
∠RQP = x + x = 2xQR = RP ⇒
∠RPQ = ∠RQP = 2x∠QRN is exterior angle of ΔQRP ⇒
∠QRN = 2x + 2x = 4x∠MRN = ∠QRN - ∠QRM = 4x - x = 3x∠MRN = ∠NMR = 3x ⇒
NR = MQNR = MQ ⇒
∠NQR = ∠QRN = 4xWe now have a straight angle MQP:
∠MQP = ∠MQN + ∠RQN + ∠RQP180° = 4x + 4x + 2x10x = 180°x = 18°Correct choice is C

Solve for x. -4x + 6(6– 2x) = -7x – 36 Select one:
a. -7
b.15
c.8
d.3
Answer:
8
-4x+6(6-2x) = -7x - 36
-4x+36-12x = -7x-36
-16x+36 = -7x-36
-16x +7x = -36-36
-9x = -72
x = 72/9
x = 8
You deposit 10,000 into a savings account that compounds quarterly. The account has an interest rate of 3.7%. What would be the value of the investment after 30 year
Answer:
30189.155
Step-by-step explanation:
Recall the compound interest formula :
A = P(1 + r/n)^nt
P = principal = 10000
r = rate = 3.7% = 0.037
n = quarterly = 4
t = 30
A = 10000(1 + 0.037/4)^30*4
A = 10000(1 + 0.00925) ^120
A = 10000(1.00925)^120
A = 10000 * 3.0189155
A = 30189.155

Oliver lives in a state with no state income tax. He pays $180 in payroll tax each week. If the federal income tax is 0.75 of the payroll tax, how much are the other taxes?
Answer:
The other taxes are $135.
Step-by-step explanation:
From the information provided, you know that Oliver pays $180 in payroll tax and that the federal income tax is 0.75 of the payroll tax, so in order to find how much are the other taxes you have to calculate the 0.75 of the payroll tax Oliver pays:
180*0.75=135
According to this, the answer is that the other taxes are $135.

Rank the following in order from most precise to least precise.
1500 grams
8.43 inches
1580 meters
5.426 seconds
Answer:
1st most = 8.43 inches
2nd most = 5,426 Seconds
3rd most = 1580 meters
4th most = 1500 grams
Step-by-step explanation:
8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.
5,426 Seconds = 01:30:26. hrs mins sec can be converted.
1580 meters = 1.58 km = 158000cm hasn't been properly converted as zeros get lost.
1500 grams = 1.5kg hasn't been precisely converted as zeros get lost.

Use the number line below to determine which of the following answer choices has statements that are all true
Answer: the last one
Step-by-step explanation: B REPRESENTS
-2 ½ . POINT D REPRESENTS 1 ¾ .
1 ¾ is bigger than -2 ½
The answer choice that has the statement that is true about the number line can be seen in the first option.
What is a number line?A number line is a pictorial representation of lines on a calibrated straight line that serves as a basis for expressing real numbers on a straight line.
We should equally note that:
The left-hand side is the negative x-axis and,The right-hand side is the positive x-axis.From the given figures;
Point A lies to the negative axis direction on point scale 4 i.e -4Point D lies extremely to another point scale so we can say it is [tex]\mathbf{1 \dfrac{3}{4}}[/tex]Since 3/4 is roughly 0.75 = 1 + 0.75 = 1.75Therefore, we can conclude that Point A represents -4, Point D represents [tex]\mathbf{1 \dfrac{3}{4}}[/tex] and [tex]\mathbf{1 \dfrac{3}{4}}[/tex] > -4.

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.
Answer:
B
Step-by-step explanation:
RQ=TV
QS=VU
RS=TU
While proving that 2 triangles are congruent you have to consider the same side for both triangles.
The mistake you made was that you presumed that since both have equal sides they are equal,
In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.
B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched
