x = 6
∠R = 12x = 72° ∠Q = 18x = 108°
A student has an average (arithmetic mean) score
of 86 points for 4 tests. What total score does this
student need in the next two tests in order to have
an average of 90 for all 6 tests?
Please help!! Thank you!
Answers
Answer:
90 & 96
Step-by-step explanation:
if you add them and mean them you will conclude this solution
The total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be 196.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A student has an average (arithmetic mean) score of 86 points for 4 tests.
The total number of 4 tests will be
→ 86 x 4
→ 344
Then the total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be
The total number of 6 tests will be
→ 6 x 90
→ 540
Then the score in the last 2 tests will be
→ 540 - 344
→ 196

Kawai requires a loan of $33,000 to buy a used sport utility vehicle. His banks offers financing at 6.75% compounded monthly, for a term of 6 years, payable monthly. What is the total cost of this loan?
Answers
Answer:
$49,126.87
Step-by-step explanation:
Given data
Principal= $33,000
rate= 6.75%
Time= 6 years
First, convert R as a percent to r as a decimal
r = R/100
r = 6.65/100
r = 0.0665 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 33,000.00(1 + 0.0665/12)^(12)(6)
A = 33,000.00(1 + 0.005541667)^(72)
A = $49,126.87
Hence the final amount is $49,126.87
The ratio of boys to girls in the class is 3 to 4. If there were 12 boys, how many girls were there?
Answers
Answer:
Step-by-step explanation:
let girls be x
3/4=12/x(do cross multiplication)
12*4=3x
48/3=x
16=x
therefore there are 16 girls
Answer:
16 girls
Step-by-step explanation:
Set up a proportion. Let x = the number of girls.
3 / 4 = 12 / x
Cross multiply:
3x = 48
x = 16
(trigonometry) solve for x
Answers
Answer:
[tex]x = 21 \sin(38 \degree) \\ x = 12.93[/tex]
The more accurate value is roughly x = 16.5482258257411
=====================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(38) = x/21
21*cos(38) = x
x = 21*cos(38)
x = 16.5482258257411 which is approximate
x = 17
I'm rounding to the nearest whole number since the other side (21) is a whole number. If your teacher instructs you to round otherwise, then follow those instructions of course. Make sure your calculator is in degree mode.

I REALLY NEED HELP PLS
Answers
Answer:
Step-by-step explanation:
100+2x+40=180(sum of interior angle of a triangle)
140+2x=180
2x=180-140
2x=40
x=40/2
x=20
Answer:
x=20
Step-by-step explanation:
the sum of the angles of a triangle is 180
so it means,
100+40+(2×)=180
140+(2×)=180
2×=180-140
2×=40
divide both sides by 2
x=20
to prove this substitute 20 inside see if the result is 180
40+100+(2×)=180
×=20
40+100+(2 (20))=180
140+40=180
140+40=180
Good luck.
