Answer:

The answer is 1/4

Step-by-step explanation:

The answer is 1/4 because

7/8-5 /8

= (7 × 8) - (5 × 8) /8 × 8

= 16/64

= 16 ÷ 16/64 ÷ 16

= 1/4

I hope this helped you.

Answer:

The answer is $\frac{1}{4}$ .

Step-by-step explanation:

Since both fractions have a common denominator of 8, you can simply subtract 7-5 in the numerator.

$\frac{7}{8} - \frac{5}{8} = \frac{2}{8}$

Simplify $\frac{2}{8}$ by dividing 2 into the numerator and denominator.

$\frac{2/2}{8/2} = \frac{1}{4}$

ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.

slava [35]

Answer:

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.

Find the value of x - if x^3-7x² - x = 0<br>a) 17 (b) 71 c) 7<br>d) 1

S_A_V [24]

Answer:

x = 0

Step-by-step explanation:

$x^3-7x^2-x =0\\$

Take out common factor

$x(x^2-7x-1) = 0$

The factor inside the parenthesis cannot be factored

Since there is a common factor that we pulled out of the original equation,

set that x equal to zero and solve

$x = 0\\$ : Therefore x = 0

The manufacturer of an energy drink spends $1.20 to make each drink and sells them for two dollars the manufacturer also has fix

dimulka [17.4K]

Let X be the number of energy drinks sold.

The manufacturer of an energy drink spends $1.20 to make each drink and sells them for two dollars the manufacturer also has fixed cost each month of $8000.

The manufacturing cost for X energy drinks is

$1.20x$

Fixed cost is $8000.

Therefore, cost function is

$C(x)=1.20x+8000$

Selling price of each drink is $2.

Therefore, the revenue function is

$R(x)=2x$

Hence, the revenue function is

$R(x)=2x$

Could anyone help me with this problem i'm stuck <br><br> h(17)= ?

nikdorinn [45]

Answer:

$\sqrt{17t}$

Step-by-step explanation:

Consider the right side of the table

It informs us of the values for h(t) for different values of t

The top one informs us what h(t) is when t = 17, that is

h(t) = $\sqrt{17t}$ , when t = 17, thus

h(17) = $\sqrt{17t}$

Find the quotient of 2,300 and (0.4 · 10-8). In your final answer, include all of your calculations.

BigorU [14]

The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
