Step-by-step explanation:

If you want it in decimal form it should be 8.94427190.. and so on it wants it to the nearest hundredth so its just 8.94? I hope this helps the exact form not in decimal form is 4√5.

Answer:

8.94

Step-by-step explanation:

(-3, -9), (1, -1)

x1 = -3

x2 = 1

y1 = -9

y2 = -1

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(1 - (-3))^2 + (-1 - (-9))^2}$

$d = \sqrt{4^2 + 8^2}$

$d = \sqrt{16 + 64}$

$d = \sqrt{80}$

$d = \sqrt{16 \times 5}$

$d = 4\sqrt{5}$

$d = 8.94$

What is 3/4 as a percentage

luda_lava [24]

Answer:

75%

Step-by-step explanation:

A percent is a value out of 100.

Change the fraction $\frac{3}{4}$ to an equivalent fraction with the denominator equal to 100.

$\frac{3}{4}$ × $\frac{25}{25}$ = $\frac{75}{100}$

This fraction represents a percent.

$\frac{75}{100}$ = 75%

PLEASE SHOW WORK A coffee distributor needs to mix a(n) Gualtemala Antigua coffee blend that normally sells for $10.30 per pound

Katarina [22]

Answer:

23 pounds of the Gualtemala Antigua Blend and 37 pounds of the Tanzanian Blend

Step-by-step explanation:

you need to make a system of equations to solve this.

First lets make x be the pounds of Gualtemala Antigua coffee blend and y the pounds of Tanzanian coffee blend

we know we need 60 pounds total so first equation is

x+y=60

Next we will make an equation based on the money information

10.30x + 13.80y = 12.46(60)

10.30x + 13.80y = 747.60

So our system of equations is

x + y = 60

10.30x + 13.80y = 747.60

I will solve this by using substitution. first rewrite x+y=60 to y=60-x

now i can substitute that into the other equation for y and solve for x

10.30x + 13.80(60-x) = 747.60

10.30x + 828 -13.80x = 747.60

-3.5x + 828 = 747.60

-3.5x = -80.4

x = 23 (rounded from 22.9714 since they requested that)

now I can use this solution to solve for y by plugging into one of the original equations

x + y =60

23 + y =60

y = 37

Finally we can say that they must mix 23 pounds of the Gualtemala Antigua Blend and 37 pounds of the Tanzanian Blend.

The ratio of men to women working for a company is 8 to 5. If there are 234 employees total, how many women work for the company

Dimas [21]

Answer:

144

Step-by-step explanation:

The ratio of men to women working for a company is 8 to 5.

Total men and women working as per the ratio is 8+5 = 13

So the ratio of men to total is

the ratio of women to total is

there are 234 employees total

To find the number of men works , we make a proportion

Cross multiply it

8 * 234 = 13x

1872 = 13x

Divide by 13 on both sides

x= 144

We will now use energy considerations to find the speed of a falling object at impact. Artiom is on the roof replacing some shin

ohaa [14]

Answer:

v = 8.49 m/s rounded off to 3 significant figures

Step-by-step explanation

Using Energy Conservation

U = Tk + Vp (Sum of kinetic Tk Energy and gravitational potential Vp Energy)

At height = 3.67 m, the hammer was still or the velocity was negligible; hence, vi = 0 m/s.
Ui = 0 + mgh
At ground all potential energy is converted to kinetic; hence, Uf = $\frac{1}{2}$ mv².
Since total energy of the system remains constant we equate Ui to Uf.
Ui = Uf
mgh = $\frac{1}{2}$ mv²
After cancelling out masses and making v the subject of the formula we get:

v = $\sqrt[2]{2gh}$ = $\sqrt[2]{2*9.81*3.67}$ = 8.49 m/s rounded off to 3 significant figures
