Which expression is a difference of squares with a factor of 5x − 8? 25x2 − 16 25x2 + 16 25x2 − 64 25x2 + 64

erastovalidia [21]

Ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer

The eastern continental trail is 15 times longer than the Erie canal way trail. The combined length of the hiking trails is 5,76

Lena [83]

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Step-by-step explanation:

Given,

Combined length of both trails = 5760 miles

Let,

x be the length of eatern continental trail.

y be the length of Erie canal trail.

According to given statement;

x+y=5760 Eqn 1

x = 15y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$15y+y=5760\\16y=5760$

Dividing both sides by 16

$\frac{16y}{16}=\frac{5760}{16}\\y=360\\$

Putting y=360 in Eqn 2

$x=15(360)\\x=5400$

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

You are making 8 cups of fruit punch for a party. You have bottles of 75% fruit juice and 25% fruit juice. How many cups of each

slavikrds [6]

Answer:

<em>4 cups of 75% fruit juice and 4 cups of 25% fruit juice should be mixed.</em>

Step-by-step explanation:

Suppose, the amount of 75% fruit juice is $x$ cups.

As the total amount of fruit punch is 8 cups, so the amount of 25% juice will be: $(8-x)$ cups.

Given that, the percentage of juice in 8 cups fruit punch is 50%

So, the equation will be.........

$0.75x+0.25(8-x)= 0.50(8)\\ \\ 0.75x+2-0.25x= 4\\ \\ 0.50x+2=4\\ \\ 0.50x= 2\\ \\ x=\frac{2}{0.50}=4$

Thus, the amount of 75% fruit juice is 4 cups

and the amount of 25% fruit juice is (8-4)= 4 cups.

Could someone help me solve this problem?

Ann [662]

Answer:

$\boxed{x=58}$ & $\boxed{m \angle C = 60}$

Step-by-step explanation:

You need to find x first in order to find the measure of angle C. To solve for x, we will use the fact that interior angles of a triangle have angle measurements that add up to 180 degrees.

Using this knowledge, we can create an equation where angles A, B, and C add up to equal 180.

$A+B+C=180$
$(x+4)+(x)+(x+2)=180$

Combine like terms on the left side of the equation.

$3x + 6 = 180$

Subtract 6 from both sides of the equation.

$3x=174$

Divide both sides of the equation by 3.

$x=58$

Now that you've found the value of x, you can use this value to plug into the expression for angle C.

$C=x+2$
$C=(58)+2$
$C=60$

Therefore, the final answer is:

$x=58\ \text{and} \ m \angle C = 60$

What is the volume of a cone with a radius of 6 cm and a height of 12 cm? use 3.14 for pi. round your answer to the nearest hund

natima [27]

The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4)
V = 452.16 cm³
