Answer:

f(x)-g(x)=x^2+9x+2

Step-by-step explanation:

f(x)-g(x)=(3x^2+6x-1)-(2x^2-3x-3)

=3x^2+6x-1-2x^2+3x+3

=(3x^2-2x^2)+(6x+3x)+(-1+3)

=x^2+9x+2

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference o

denis23 [38]

Option D. 96 is the correct answer.

Explanation:

Let the higher grade be = x

Let the lower grade be = y

As given, The difference of the two grades is 16

$x-y=16$ or $x=16+y$ .... (1)

The sum of one-eighth of the higher grade and one-half of the lower grade is 52.

$\frac{1x}{8}+\frac{1y}{2}=52$ ... (2)

Putting the value of x=16+y in equation (2)

$\frac{16+y}{8}+\frac{y}{2}=52$

$\frac{16+y+4y}{8}=52$

$\frac{16+5y}{8}=52$

$16+5y=416$

$5y=400$

$y=80$

As x=16+y

x=16+80 = 96

Hence, higher grade is 96.

PLEASE HELP will give 99 points.

Yuri [45]

The answer is 90 + 45 because BOC is a right angled triangle where angle BOC is 90 and angle BOK is 45 because 90 ÷2. A OK Is a right angled triangle so angle AOB is 90 as well so to find angle AOK we plus 90 and 45 which is 135 degrees.

A 3% salt solution weighing 100g represents 100g of water in which 3g of salt is dissolved (=3/10). What amount of salt would be

Nadya [2.5K]

Answer:

There would be 12 g of salt (12.3 g actually but rounded) and 88g of water (88.7 g actually but rounded)

Step-by-step explanation:

From the question, a 14% salt solution means 14g of salt in 100g of water.

What this means is that, the fraction of salt to water in the solution would be 14/100 which is same as 7/50

Now, we want to know the amount of salt and the amount of water in a 100g of 14% salt solution.

Looking at the ratio salt to water, we have 7 to 50

For every 50 parts of water, there are 7 parts of salt.

So the ratio of both is 7:50

For salt, the amount in grammes present will be ;

7/(50 + 7) * 100g = 7/57 * 100 = 12.3 g or 12g to the nearest whole number

The amount in grammes of water present will be ;

50/(50 + 7) * 100g = 50/57 * 100 = 87.7g or 88g to the nearest whole number

Maria adopted for dogs altogether they ate 1 3/4 pound of food each day 1 pound is equal to 16 ounces how many ounces of food wi

olga55 [171]

Answer:

65 ounces

Step-by-step explanation:

Number of dogs = 4

Each day, they ate 13/4 pounds of food

1 pound = 16 ounces

If 4 dogs eat 13/4 pounds of food

1 dog will eat x pounds of food

1 dog will eat = (1 * 13/4) / 4 = 13 /16

1 dog will eat 13 / 16 pounds of food each day.

1 pound = 16 ounces

13 / 16 pounds = y ounces

y = (13/16 * 16) / 1

y = 13 ounces

Each dog eats 13 ounces of food daily.

In five days, each dog will eat 13 * 5 = 65 ounces of food.
