Please answer me x and y ​

Answers

Answer: x=5√3(you've got it correct!)

y=15

In∆ADC,

Cos 60°=DC/10

DC=5

y=20-5

y=15

Answer:

x = 5√3

y = 15

Step-by-step explanation:

Look at the picture.

ΔABC, ΔDBA and ΔDAC are the triangles 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

Therefore

in ΔDAC:

DC : AD : AC = 1 : √3 : 2

If AC = 10, then DC = 10 : 2 = 5 and AD = x = 5√3

in ΔDBA:

AD : BD : AB =  1 : √3 : 2

If AD = 5√3, then AB = 2 · 5√3 = 10√3 and BD = y = 5√3 · √3 = 5 · 3 = 15

the tickets for a benefit concert were $6 for friday night and $8 for Saturday night. the total attendence for the two nights was 1090 people. if the total receipts for the two nights were 7856 how many people attended each night

Answers

Answer:

432 people on Friday and 658 on Saturday

Step-by-step explanation:

Lets use variables for each day

x=Friday and y=Saturday

now write two equations since you were given two different information (money and people)

$6 on Friday and $8 on Saturday with a total amount of $7856

the equation will be 6x+8y=7856

now the second equation will be for people

x amount of people on Friday and y amount of people on saturday for a total of 1090; the equation will be

x+y=1090

put them together

6x+8y=7856

x+y=1090

now you can cancel a variable but manipulating one of the equations. We'll use x, to cancel x you need make it zero so multiply the bottom by -6

6x+8y=7856

-6(x+y=1090)

6x+8y=7856                   now subtract downwards, with the x cancelling

-6x-6y=-6540

2y=1316                          simplify

(2y/2)=(1316/2)              

y=658

                                       insert y into x+y=1090

x+(658)=1090

    -658   -658

x=432

A contractor completed the construction of two buildings last year The Keslo building cost 84.5 million
The Jones building cost 33.8 million

which statement is true when comparing the costs of the two buildings?

A: Keslo cost 2 1/2 times the cost of Jones

B: Jones cost 2/3 the cost of Keslo

C: Jones cost 1/2 the cost of Keslo

D: Keslo cost 3 1/2 times the cost of Jones


Is the answer D?

Answers

D Is Incorrect, Because 33.8*3 = 101.4. C Is Incorrect, Because 1/2 * 84.5 = 42.25. B Is Incorrect, Because 2/3*84.5 = 56 and 1/3. A Is Correct, Because 2.5*33 = 84.5. So, The Answer Is A.

5 to the third power times 25

Answers

Okay, to do "powers", which is exponents, just multiply the number by itself.

So, 5 to the third power, or 5 cubed, or simply 5³, is equal to 5 x 5 x 5.

5*5=25 \n 25*5=125
We get 125.

Now multiply 125 by 25.
125*5=3125

Our final answer is 3125.

The value of expression which is expressed as "5 to the third power times 25" is 3125.

To calculate the value of the expression "5 to the third power times 25," we start by finding the value of 5 raised to the power of 3. This means multiplying 5 by itself three times: 5 × 5 × 5. The result is 125.

Next, we multiply this result by 25. Multiplying 125 by 25 gives us 3125. Therefore, the value of the expression "5 to the third power times 25" is 3125. This means that when we raise 5 to the power of 3 and then multiply it by 25, we get the final result of 3125.

Therefore, the required value is 3125.
