Answer:
91
Step-by-step explanation:
Mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be his test score of his last test , then
[tex]\frac{86+70+72+100+96+80+x}{7}[/tex] = 85 ( multiply both sides by 7 )
504 + x = 595 ( subtract 504 from both sides )
x = 91

Mi tarjeta de crédito está saturada por lo que tanto recurre un préstamo que cobra el 8% mensual por la cantidad que se solicite me prestaron 3500 cuál es la cantidad de que debo pagar al prestamista en un mes para saldar la deuda
Answer:
El valor que debes pagar al prestamista en un mes para saldar la deuda es: 3780.
Step-by-step explanation:
Para encontrar el valor que debes pagar en un mes para saldar la deuda, debes calcular el 8% del valor que te prestaron y este sería el monto de los intereses. Después, debes sumarle esta cantidad al valor que te prestaron:
monto del préstamo= 3500
3500*8%=280
3500+280=3780
De acuerdo a esto, la respuesta es que el valor que debes pagar al prestamista en un mes para saldar la deuda es: 3780.

Enter the correct answer in the box. What are the solutions to the equation (x - 21)^2 = 25?
Answer:
x = 26
Step-by-step explanation:
[tex] {(x - 21)}^{2} = 25 \\ x - 21 = \sqrt{25} \\ x - 21 = 5 \\ x = 5 + 21 \\ x = 26[/tex]
Answer:
x = 26, x = 16.
Step-by-step explanation:
(x - 21)² = 25
Expand the factor.
(x - 21)(x - 21) = 25
Multiply using FOIL.
x² - 42x + 441 = 25
Subtract 25 from both sides.
x² - 42x + 416 = 0
Factor.
(x - 26)(x - 16) = 0.
Set both expressions to 0 and solve.
x - 26 = 0
Add 26 to both sides.
x = 26
x - 16 = 0
Add 16 to both sides.
x = 16
WHAT IS THE MEDIAN pls help
two lines intersect in the figure below. what is the value of x?
Answer:
A. 17
Step-by-step explanation:
The angles are adjacent, meaning they are congruent. So you will set (5x + 6) equal to 91
(5x + 6) = 5x + 6
5x + 6 = 91
5x + 6 - 6 = 91 - 6
5x = 85
5x / 5 = 85 / 5
x = 17

Step-by-step explanation:
Solve for x. round your answer to the nearest whole degree.
Answer:
64°
Step-by-step explanation:
sin(x) = 17/19
take inverse sine of 17/19: [tex]sin^{-1}(17/19)[/tex] = 63.475°
they want to the nearest whole degree, so it would be ≈ 64°

express 4.77777..... in the form of p/q
Answer:
[tex]\frac{43}{9}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 7 placed after the decimal point.
let x = 4.7777... → (1)
Multiply both sides by 10
10x = 47.7777.... → (2)
Subtract (1) from (2) thus eliminating the repeating 7
9x = 43 ( divide both sides by 9 )
x = [tex]\frac{43}{9}[/tex]

Answer:
m<CAO = 56°
Step-by-step explanation:
Same-side interior angles are supplementary to each other, so take their sum and set them equal to 180 and solve for x:
2x + 3x + 40 = 180
5x + 40 = 180
5x = 140
x = 28
Plug x=28 into angle CAO:
CAO = 2(28) = 56°
Find the next term of the following sequence.
9, 6, 4, .....

3(x−6)=−12 what is the answer pls
Answer:
[tex]3(x - 6) = - 12 \\ 3x - 18 = - 12 \\ 3x = - 12 + 18 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2[/tex]
ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ
Answer:
x = 2
3 (x-6) = -12
3x - 18 = -12
3x - 18 + 18 = -12 + 18
3x = 6
3x/3 = 6/3
Hence, x= 2

Write 5.3421 (bar on 21) in p/q form
Answer:
[tex]\frac{52887}{9900}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 21 placed after the decimal point.
let x = 5.34212121 ( multiply both sides by 100 and 10000 )
100x = 534.2121... → (1)
10000x = 53421.2121... → (2)
Subtract (1) from (2) thus eliminating the repeating 21
9900x = 52887 ( divide both sides by 9900 )
x = [tex]\frac{52887}{9900}[/tex]
