ur welcome
which expression can be an integer when simplified? i will give so many points and brainliest plz answer!
a.6^-3/6^-1
B. 12^-2/12^2
C. 2^-10 x 2^3
D. 4^7 X 4^-2
Answer:
D
Step-by-step explanation:
when simplify 4^7, using a calculator, you get 16384. When you simplify 4^-2 , you get 0.0625. When multiplied together, the total is 1024, which is an integer. Answer a, b, and c were not integers, because when multiplied or divided, the answer was less than zero and showed up as a decimal starting with 0.*** . An integer is defined as any whole number, and not a fraction, therefor D is the only correct answer.

Step-by-step explanation:
The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count for a serving of food can be computed using the formula C=4h+9f+4p, where his the
of grams of carbohydrate contained in the serving, is the number of grams of fat contained in the serving, and is the number of grams of protein contained in the serving
A serving of a certain type of but contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. How many calones are in this serving of ruts?
There are calories [___] in this serving of nuts
Answer:
152 calories
Step-by-step explanation:
The calories count, composition of carbohydrates, fat and protein are related by;
C = 4h + 9f + 4p
where C, h, f, and p have there given meaning.
Given that the serving of a type of nut contains; f = 12 grams, h = 6 grams and p = 5 grams, then;
C = 4(6) + 9(12) + 4(5)
= 24 + 108 + 20
= 152
C = 152 calories
Therefore, there are 152 calories in the serving of the certain type of nut.

A dog walker earns $10 plus $3 per dog. What equation represents this model?
Write an equation that could be used to find three consecutive odd integers whose sum is -3
Answer:
2x+1 + 2x+3 + 2x+5 = -3Step-by-step explanation:
2x+1 - the first odd integer
2 x+1 + 2 = 2x+3 - the next odd integer consecutive to 2x+1
2x+3+2 = 2x+5 - the odd integer consecutive to 2x+3 (the third consecutive odd integer)
2x+1 + 2x+3 + 2x+5 - the sum of three consecutive odd integers
therefore the equation:
2x+1 + 2x+3 + 2x+5 = -3
6x + 9 = -3
6x = -12
x = -2
2x+1=2(-2)+1=-3
2x+3=2(-2)+3=-1
2x+5=2(-2)+5=1
the three consecutive odd integers whose sum is -3 are: -3,-1,1

What is the slope of the line that passes through the points (9,5) and (21,1)? Write your answer in simplest form.
Answer:The slope of the line would be 1/3 because if you put those two coordinates in the table then you can see the the difference between 5 and 1 is 4 and the difference between 9 and 21 is 12 then do 4 divided by 12 and you get 1/3 for your slope.

Answer: the awnswer is 3 i think hope you pass
Step-by-step explanation:
The equation f equals 9/5 C + 32 relates temperature measured in degrees celsius C to degrees Fahrenheit f Determine whether there is a proportional relationship between C and F explain your reason
Given:
[tex]F=\dfrac{9}{5}C+32[/tex]
where, F is degree Fahrenheit and C is degree Celsius.
To find:
Whether there is a proportional relationship between C and F.
Solution:
We know that, proportional relations is defined as
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
So, the line of proportional relationship passes through (0,0) and the equation must be true for (0,0).
If there is a proportional relationship between C and F, then the equation must be true for (0,0).
Substituting F=0 and C=0 in the given equation, we get
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is false because [tex]0\neq 32[/tex].
It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.
Hence, there is not a proportional relationship between C and F.

How would i do this??:: Some kinds of fruit juice are only 10% juice. Other brands are 40% juice how much of each kind of juice should be mixed together to form 5 gallons of punch which is 25% juice?
Answer:
You should mix
2.5 gallons of the first juice with
2.5 gallons of the second juice
Step-by-step explanation:
Step one
Let the first kind of juice be x
Let the second be y
Given x contain 10% juice
and y contains 40% juice
So for the percentage constituent concentration of each the expression is
0.1x+ 0.4y=0.25(5)
0.1x+0.4y=1.25—----------------1
Step two
Also for the volume of the mixture, we are working with 5 gallons hence the expression
x+y=5-------------------------------2
The system of equation for the situation is
0.1x+0.4y=1.25------1
x+y=5-------------------2
From equation 2
x=5-y
Put x=5-y in the equation
0.1(5-y) +0.4y=1.25------1
0.5-0.1y+0.4y=1.25
0.3y=1.25-0.5
0.3y=0.75
Dividing both sides by 0. 3
y=0.75/0.3
y=2.5
x=5-y
x=5-2.5
x=2.5
The mixture should consist of
2.5 gallons of the first juice with
2.5 gallons of the second juice
A pitcher can hold 5.2 liters of water. How many 0.4 liter glasses of water can be poured from the pitcher? *
13 glasses can be poured
Hope I helped
Answer:
13
Step-by-step explanation:
number of glasses = total quantity of water / quantity of one cup
n = 5.2/0.4
n = 52/4 (multiply numerator and denominator with 10)
n = 13
therefore it can be poured into 13 cups
Marshall is writing an equivalent equation to solve for x. What should be his next step? 5 x + 4 y = 8. 5 x + 4 y minus 4 y = 8 minus 4 y. 5 x = 8 minus 4 y.
Answer:
d)Divide both sides of the equation by 5.
Step-by-step explanation:
Marshall is writing an equivalent equation to solve for x. What should be his next step?
5x+4y=8
5x+4y-4y=8-4y
5x=8-4y
a)Add 5x to both sides of the equation.
b)Subtract 5x from both sides of the equation.
c)Multiply both sides of the equation by 5.
d)Divide both sides of the equation by 5.
5x + 4y = 8
Subtract 4y from both sides
5x + 4y - 4y = 8 - 4y
5x = 8- 4y
Divide both sides by 5
5x / 5 = (8 - 4y) / 5
x = (8 - 4y) / 5
Marshall's next step should be to divide both sides of the equation by 5
Answer: D)Divide both sides of the equation by 5.

Determine the measures of angles C and D.
Answer:
c = 40 and d = 76
Step-by-step explanation:
this is going to take me a long time to explain but here we go
so you need to do 180 - 116 and get 64.
then create a equation that is like this 7y + 6 + 4y + 64 = 180
when you solve it you get y = 10
then plug in 10 in for y in 4y. and you get 40 for c
do the same for d and you will get 76
