15% of ___ is 80. I cross multiplied by doing 15/100=12/x —> 45(x)=27(100)—> 45x=2700 —> 45x/45=2700/45 so x, or __, =60.

I need help if you look at the answers, b and c are the same. What do I pick?

Temka [501]

Answer:

We have to choose any one from option B and option C

Step-by-step explanation:

We have to perform a subtraction of two decimal numbers.

(9.43 - 4.286) = (9.430 - 4.286) = 5.144.

Hence, the answer is 5.144 which is given both options B and C.

In case there are two options with the same value and the value is the answer, then you choose any one of them but not both.

Here in our case, we have to choose any one from option B and option C and we will be rewarded full marks. (Answer)

Find the value of x and the value of y.

Eddi Din [679]

Answer:

Option A

Step-by-step explanation:

To find all missing sides of a right triangle we use the sine, cosine or tangent ratio as below,

sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

tanθ = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Now we take an angle measuring 60°

sin(60°) = $\frac{6}{y}$

$\frac{\sqrt{3} }{2}=\frac{6}{y}$

y = 4√3

tan(60°) = $\frac{6}{x}$

√3 = $\frac{6}{x}$

x = 2√3

Therefore, Option A will be the correct option.

sladkih [1.3K]

Step-by-step explanation:

let,the sum of the ages of chukwu & Caroline be X & Y.

now,

X+y=45

X-y=3

(+) (+) (-)

__________

2x=42

or,X=42/2

or,X=21

putting the value of X,

X+y=45

or, 21+y=45

or,y=45-21

or,y=24

therefore,X=21

y=24

How much artificial turf should be purchased to cover an athletic field that is in the shape of a trapezoid with a height of H =

Nata [24]

Answer:

581 m²

Step-by-step explanation:

The area of a trapezoid is determine as the average between the length of both bases T and B (46 and 37 m) multiplied by the height H. The area is:

$A = H*\frac{(T+B)}{2}\\A = 14*\frac{(46+37)}{2}\\A= 581 m^2$

Assuming that enough turf must be bought to cover the whole extension of the field, the amount of turf that should be purchased is 581 m².
