find two numbers whose ratios is 3 to 5 and whose sum is 88​

Answers

Answer:

33 and 55

Step-by-step explanation:

[tex]\frac{x}{y}: \frac{3}{5}[/tex]

x + y = 88

3 + 5 = 8

[tex]y(\frac{x}{y}): y(\frac{3}{5})[/tex]

[tex]x= \frac{3}{5}y[/tex]

[tex]y+\frac{3}{5}y=88[/tex]

[tex]\frac{8y}{5}=88[/tex]

[tex]5(\frac{8y}{5})=5(88)[/tex]

8y = 440

8y ÷ 8 = 440 ÷ 8

y = 55

x + y = 88

x + 55 = 88

x + 55 - 55 = 88 - 55

x = 33

Samuel made a list of his test scores: 88, 100, 92, 80, 85, 94, and 90. What is the lowest test score he can get on his next test to have mean score of 90?

Answers

Answer:

he needs to get a 91 to have a mean score of 90

Step-by-step explanation:

add up all the known scores to get 629

let 's' = lowest test score

(629 + s) ÷ 8 = 90   [we divide by 8 because there are 7 known and 1 unknown score)

cross-multiply to get:

629 + s = 720

s = 720-629

s = 91

A machine depreciate in value at the rate of 10% every year on reducing balance. if the original cost is 20000 and the scrapped value is 13122, how long has the equipment been used?

Answers

Mark Brainliest please


Answer: 10 years

Explanation:


The original cost of the machine = 20000

The scrap value of the machine = 13122

Value of the machine = ( 20000 - 13122 ) = 6878

Depreciation of the machine for the first year = ( 6878 * 10 % )
= 687.8
So, the effective life of the machine is = ( 6878 / 687.8 )
= 10 years

triangle area ?​

Answers

25 root 3 divided by 2
Base is 5. Height is 5 root 3
Multiply then divide by 2

Answer:

A= 21.65063509

Step-by-step explanation:

triangle area is =base*hight/2

Because we have a right triangle we can apply the trigonometric functions

sin30 =base/hypothenuse = base/10

cos 30 = hight/hypothenuse =hight/10

sin30 = base /10  ; multiply both sides by 10

base = 10*sin30

cos 30 = hight /10 ; multiply both sides by 10

hight = 10 cos 30

A= 10*sin30*10*cos30/2 =

      100*sin 30*cos 30/2=

            50*sin30*cos30 = ; use calculator make sure is set up in degrees

Answer:

-2?

Step-by-step explanation:

use y2-y1 over x2-x1 to find the answer. So you would do -2--5/3 over 4--2. The two negitives turn into a positive. SO it is now -2+5/3 over 4+2. -2+5/3= -1/3 over 4+2=6 it is now -1/3/6 which equals -2. So I think the answer is -2. I do not know if you should trust me on this but I tried.

Answers

Answer:

1. ₹ 382.50

2. 14,583.33

Step-by-step explanation:

Interest  = p × r × t

p = principal amount

r = rate of interest

t = time in years

(1) Interest = 10,200 × 0.025 × 1.5

                 = ₹ 382.50

(2) Principal = [tex]\frac{I}{(r\times t)}[/tex]

                   = [tex]\frac{1750}{(0.04 \times 3)}[/tex]

                   = [tex]\frac{1750}{0.12}[/tex]

                  = ₹ 14,583.33

(3)  [tex]Rate=\frac{(I \times 100)}{(p \times t)}[/tex]
