Answer:

You can find 0.5% of a number by multiplying the number by

Step-by-step explanation:

Answer:

13)  8r = 256;   r = 32

14)  f = 2(5)

15)  8t = 208;    208/8 = 26

Step-by-step explanation:

Answer:

$4

Step-by-step explanation:

Given that

total cost of 8 identical pens and 2 identical files is $32

And, the The total cost of 3 such files would be the same  as the total cost of 4 such pens

We need to find out the cost of each file

So let us assume the following things

Pens be x

File be y

Now

8x + 2y = $32 ....(1)

3y = 4x.........(2)

y =  4x÷ 3

Now put the value of y in equation 1

8x + 1.33x = 32

x = $3.55

x = $4

The cost of each file based on the given information is $4

where:

If the total cost of 8 identical pens and 2 identical files is $32, hence;

8x + 2y = 32

If the total cost of 3 such files is the same as the total cost of 4 such pens, then;

4x = 3y

From the equation

8x + 2y = 32

2(4x) + 2y = 32

2(3y) + 2y = 32

8y = 32

y = 4

Since 6=4x = 3y

4x = 3(4)

4x = 12

x= 3

Hence the cost of each file is $4

Answer:

8.77 or 8.80

Step-by-step explanation:

sin (20) = 3/x

x (sin)20)) = 3

divide by sin(20)

x= 8.77 or 8.8

Answer:

31.4

Step-by-step explanation:

Answer:

2x + 20 = 3x-10

2x -3x = -20-10

-x = -30

x= 30

Checking part:

2x+20 = 2(30) +20 = 60+20 = 80

3x-10 = 3(30) - 10 = 90-10 = 80

Hence, the final answer is x = 30.

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

the angle should be the same so,

2x+20=3x-10

x=30

what do you mean find y? I can't see it

Answer:

x = 11 explanation : " $3 subtracted from the cost of the book just number 8! " As an equation this would be : x - 3 = 8 SOLVE x - 3 = 8   + 3  + 3 x = 11 KEY x = cost of book

Answer:

11.06 meters

Step-by-step explanation:

Given that

The height of a regulation soccer goal is 2.4 meters

And, the distance is 10.8 meters

We need to find out the hypothesis

Here we applied the pythagoreans theorem

So,

= √ (2.4m) ^2 + (10.8 m) ^2

= √5.76 m^2 + 116.64m^2

h = 11.06 m

Hence, the hypothesis is 11.05 meters

Answer:

The interval is [4,7]

Step-by-step explanation:

The rate of change is given by

f(x2) - f(x1)

-------------------

x2 -x1

We want the rate of change to be 56

f(x2) - f(x1)

-------------------  = 56

x2 -x1

We also know that the x2 is 7  so f(x2) = 192

192 - f(x1)

-------------------  = 56

7 -x1

192 - f(x1) = 56( 7 -x1)

192 - f(x1) = 392 -56x1

Now we need to pick points from the table and see where it is true

(6,96)

192 - 96 = 392 -56*6

96=56  False

( 5,28)

192 - 28 = 392 -56*5

164=112  False

(4,24)

192 - 24 = 392 -56*4

168=168  True

The interval is [4,7]

Answer:

68 degrees

Step-by-step explanation:

The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.

The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft.  Thus,

tan x = (opp side) / (adj side) = 10/4.  Using the inverse tangent function, we find that the angle in question is

arctan (10/4) = 68 degrees

Answer:

18

Step-by-step explanation:

( 3 + √3 ) ( 5 - √2 )

= 3 ( 5 - √2 ) + √3 ( 5 - √2 )

= 15 - 3√2 + 5√3 - √6

√2 = 1.41 ( approximately )

3√2

= 3 x 1.41

= 4.23

√6 = 2.44

√3 = 1.73

5√3

= 5 x 1.73

= 8.65

15 - 3√2 + 5√3 - √6

= 15 - 4.23 + 8.63 - 2.44

= 15 + 8.63 - 4.23 - 2.44

= 15 + 8.63 - 6.67

= 15 + 1.93

= 16.93

Rounding of 16.93 = 17

17 is near to 18.

So, 18 can be the answer.
