Answer:
x=19.75
Step-by-step explanation:
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
Which number equals 3^-3
Answer: It would equal 1/27.
Step-by-step explanation: Any number raised to a negative exponent, essentially means you reciprocal to get rid of the negative. After that, you do the math for the number in the denominator, without considering the negative sign. You could also do it the other way, do the function first without the negative, 3^3 is 27 and then applying the negative, reciprocal it to 1/27.
In the previous question, we determined that if you borrow $3,000 on an 8% discounted loan for 9 months, the amount you actually receive will be $2,820. Given this, what is the effective interest rate on the loan you receive? Express your answer as a percentage rounded to the nearest tenth of a percent if necessary, but do not include the percent sign.
Answer: 8.5%
Step-by-step explanation:
I=Prt
180=(2,820)r(3/4)
180=2,115r
R=180/2,115
r≈8.5%
The effective interest rate is approximately 8.5%, about half a percent higher than what was advertised.
Monic and Rachel purchased a tv for $378. Monica paid $36 less then Rachel. How many did each person pay for the tv? Solve using substitution or elimination. Plz answer quick
Answer:
Monica paid $171 while Rachel paid $207
Step-by-step explanation:
We are told that Monic and Rachel purchased a tv for $378.
Let the amount spent by Monica be X and the amount spent by Rachel be Y.
Thus;
x + y = 378 - - - - (eq 1)
We are told that Monica paid $36 less then Rachel. Thus;
y = x + 36
Or y - x = 36 - - - (eq 2)
Add eq 1 & eq 2 together to give;
2y = 378 + 36
2y = 414
y = 414/2
y = $207
Put 207 for x in eq 1 to get;
x + 207 = 378
x = 378 - 207
x = $171
Thus;
Monica paid $171 while Rachel paid $207

What is the slope of the line on this graph between 10 and 20 seconds?
Answer:
3m/s
Step-by-step explanation:
delta y = 40m - 10m = 30m
delta x = 20s - 10s = 10s
slope = delta y / deltax = 30m / 10s = 3m/s
-0.59x+0.29=7.2 HELP ME PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Answer:
Step-by-step explanation:
-0.59x+0.29=7.2
-0.59x+0.29-0.29=7.2-0.29
-0.59x=7.2
divide both sides by -0.59
x=− 11.7118644
that can be rounded to x= -11.7
Answer:
x=-11.7
Step-by-step explanation:
-0.59x+0.29=7.2
subtract 0.29 on both sides to isolate x
-0.59x=6.91
divide -0.59 from both sides (will be a large number)
-11.711864
x=-11.7

Alaine has 1 gallon of paint. She is going to pour it into a paint tray that measures 10 inches wide, 12 inches long, and 5 cm deep.
(1 gallon = 231 in3, 1 inch = 2.54 cm)
Answer:
First, solve for the volume of the tray by the equation V = L x W x H. Convert first all the dimensions to inches. The operation gives an answer of volume equal to 236.22 in³. Converting the amount of paint available to in³. This gives an answer of 231 in³. Hence, the answer is letter B.

If X1, X2, . . . , X16 is a random sample of size 16 from the normal distribution N(50, 100), determine(a) P ( 796.2 < 2(X; – 50)2 < 2630)(b) P ( 726.1 = E(Xi – X)= 2500
Answer:
(a) 0.90
(b) 0.9001
Step-by-step explanation:
[tex]X_{i}\sim N(50, 100);\ i=1,2,3...16[/tex]
(a)
[tex]P ( 796.2 < \sum\limits^{16}_{i=1}{(X_{i} - 50)^{2} < 2630)=P ( \frac{796.2}{100} < \sum\limits^{16}_{i=1}{(\frac{X_{i} - 50}{10})^{2} < \frac{2630}{100})[/tex]
[tex]=P ( 7.962 < \sum\limits^{16}_{i=1}{Z_{i}^{2} < 26.3)\\=P ( 7.962\leq \chichi^{2}_{16} \leq 26.3)\\\\=P(\chi^{2}_{16}\leq 26.3)-P(\chi^{2}_{16}\leq 7.962)\\\\=0.90[/tex]
*Use the chi-square table.
(b)
[tex]P ( 726.1< \sum\limits^{16}_{i=1}{E(X_{i}-\bar X)^{2} < 2500)=P ( \frac{726.1}{100} < \frac{(n-1)S^{2}}{\SIGMA^{2}}< \frac{2500}{100})[/tex]
[tex]=P ( 7.261\leq \chi^{2}_{16-1} \leq 25.0)\\\\=P(\chi^{2}_{15}\leq 25.0)-P(\chi^{2}_{15}\leq 7.261)\\\\=0.9001[/tex]
*Use the chi-square table.

Answer:
[tex]x = 45[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have that x and 3x are on a straight line
and angle on a straight line sum up to 180
In other words:
[tex]x + 3x = 180[/tex]
[tex]4x = 180[/tex]
Divide through by 4
[tex]\frac{4x}{4} = \frac{180}{4}[/tex]
[tex]x = \frac{180}{4}[/tex]
[tex]x = 45[/tex]
Hence, the measure of x is 45 degrees

Look at the figure, PQRS. Find the values of x and y.
A. x=7, y=10
B. x=6, y=8
C. x=5, y=7
D. x=6, y=9
Answer:
C. x = 5, y = 7
Step-by-step explanation:
Diagonals of a parallelogram bisects each other. Therefore:
[tex] 2x = y + 3 [/tex], and,
[tex] x + 2 = y [/tex]
✔️To find the value of x, substitute y = (x + 2) in [tex] 2x = y + 3 [/tex].
Thus:
[tex] 2x = (x + 2) + 3 [/tex]
[tex] 2x = x + 2 + 3 [/tex]
[tex] 2x = x + 5 [/tex]
Subtract x from each side
[tex] 2x - x = 5 [/tex]
[tex] x = 5 [/tex]
✔️To find y, substitute x = 5 in [tex] x + 2 = y [/tex].
Thus:
[tex] 5 + 2 = y [/tex]
[tex] 7 = y [/tex]
[tex] y = 7 [/tex]

PLEASE HELP!! Will mark brainliest, i’m struggling. Please find PR.
Answer:
PR = 15
Step-by-step explanation:
PR = PQ + QR
10x - 45 = 3 + x + 6 {Combine like terms}
10x - 45 = 9 + x {Subtract 'x' from both sides}
10x - x - 45 = 9
9x - 45 = 9 {Add 45 to both sides}
9x = 9 +45
9x = 54
x = 54/9
x = 6
PR = 10x - 45
= 10*6 - 45
= 60 - 45
PR = 15
