Answer:70%

Step-by-step explanation: 30 + 40 grams = 70

70 Grams

Answer:

the first one?

Step-by-step explanation:

I am like 67% sure.

Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.

Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;

14+3x=56

hope this helps <3

Answer:

2/3

Step-by-step explanation:

Firstly we get the y value at both x points

At x = 1

y = 2/3 + 1/2 = (4 + 3)/6 = 7/6

At x = 2

y = 4/3 + 1/2 = (8 + 3)/6 = 11/6

The slope formula is

m = (change in y)/change in x

The slope is thus;

(11/6-7/6)/(2-1) = 4/6 = 2/3

Becuase 6 nickels add up to 30

Answer:

there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.

the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%

the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%

the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%

Answer:

B; 4/d-6

Step-by-step explanation:

We want to perform a division here

Flipping the right hand side while changing the sign to multiplication, we have that;

(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3

= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3

= 2/(d^2 + 2d - 48) * 2d + 16/1

2/(d-6)(d + 8) * 2(d + 8)/1

= 2/d-6 * 2/1

= 4/d-6

Answer:

1 Bag = 12.3 Ounces

5 Bags = 61.5 Ounces

123 Ounces = 10 Bags

Step-by-step explanation:

24.6 divided by 2 is 12.3.

12.3 times 5 is 61.5

61.5 times 2 is 123.

What interest is this. Simple or compound? Cause both have different formulas.

Simple interest

A(interest) = (Principal× Rate×time)

A= (P ×3×2years)/100%

$45 = 6/100P

4500= 6p

4500/6 = P

principal= $750.

Answer:

f(x) = -1/x

Step-by-step explanation:

Here, we want to find the function that is not linear

A linear function is of the form;

y = mx + b

where m can be zero, or b can be zero

The only option that does not follow this description is

f(x) = -1/x

Answer:

Kayla is correct

Step-by-step explanation:

For a vertical line, the x-value is the same

This means there is no change in the x value

A slope is calculated by dividing by the change in x value

since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined

This means that Kayla is correct

Answer:

The value of a is 25

Step-by-step explanation:

When two angles are supplementary, they add up to 180 degrees

Mathematically,

(30 + 2a) + (125-a) = 180

30 + 2a + 125 - a = 180

a + 155 = 180

a = 180-155

a = 25 degrees

Answer:

RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)

3x +2 = 5x -3 (subtract 5x from both sides)

-2x +2 = -3 (subtract 2 from both sides)

-2x = -5 (divide both sides by -2 to isolate x)

x = 2.5 (take the value of x and plug it into the expression given for RS)

3(2.5) +2 (multiply)

7.5 +2 (add)

9.5 (this is the length of RS)

Step-by-step explanation:

I hope this helps :)
