7/8

Step-by-step explanation:

we need to same denominator. 3/4 is equal to 6/8

1/8+6/8 is 7/8.

Answer:

7/8 or 0.875

Step-by-step explanation:

1/8 + 3/4=?  

The Least Common Multiple (LCM) of 8 and 4 is 8. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

1/8 + 3/4= 1/8 + 3 x 2 = 1/8 + 6/8

                         4 x 2

Now that the fractions have like denominators, add the numerators:

1/8  + 6/8 = 1+6 = 7/8

                    8

Answer:

D. [tex]g(x)=(x+4)^{2}-3[/tex]

Step-by-step explanation:

g(x) is a translated function. Compared to the parent function, f(x)=[tex]x^{2}[/tex], it has been shifted 4 left and 3 down. The rule for quadratic functions is [tex]y=a(x-h)^{2} +k[/tex], where h is the x-translation (horizontal) and k is the y-translation (vertical). In g(x) h=-4 and k=-3. While it might seem like h is positive, remember that since in rule it is being subtracted it must be negative.

PLEASE HELP! The AHS football team did a weigh-in at the start of training camp and the weights of the players were distributed normally. There were 60 players
at the start of camp. How many players are within one standard deviation of the mean?

Answers

This is very simple. All you have to do is multiply 60, the number of players, with 68% the proportion of players that are within one standard deviation from the mean.
Therefore:
60*0.68= 40.8
You should go with 40 players in this case to be conservative but if ur teacher says otherwise go with 41

suppose you fill the cone with water and empty the water into the cylinder. how many times will you empty the water from the cone into the cylinder.

A. 3 TIMES B. 6 TIMES C.9 TIMES

Answers

Answer:  A) 3 times

=========================================================

Explanation:

Recall that from a previous screenshot you posted, that

[tex]\text{Volume of Cone} = \frac{1}{3}*\left(\text{Volume of Cylinder}\right)[/tex]

If we multiply both sides by 3 and swap both sides, then we end up with

[tex]\text{Volume of Cylinder} = 3*\left(\text{Volume of Cone}\right)[/tex]

So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.

Soil sells for 8 1/4 cents per pound. how much would you save if you bought a 100 pound sack for $7.45?

Answers

$8.25 x 100 pounds= $825
$7.45 x 100 pounds= $745
825-745= $80
therefore you save $80

The amount saved is $0.80 or 80 cents.

Since Soil sells for 8 1/4 cents per pound, the coat for 100 pound sack will be:

= 8 1/4cents × 100

= 8.25 cents × 100

= 825 cents

Since 100 cents = $1

825 cents = 825/100

825 cents = $8.25

Since the 100 pound sack was bought for $7.45, the amount saved will be:

= $8.25 - $7.45

= $0.80
