Find the sum (4d+9)+(7n-4)+(9y+5)

Answers

Answer 1

Answer:

4d + 7n + 9y + 18

Step-by-step explanation:

Add like terms, like terms are terms that have the same variable and power, For ex: 4d and 2d are like temrs so u can add them but 4d and 4d^2 are not cause they have different power(the ^2 thing).

(4d+9)+(7n-4)+(9y+5)

add like terms

4d + 7n + 9y + 18

A.5 × 10-7
B.5 × 10-1
C.5 × 10-10
D.5 × 107

Answers

Answer:

1.32 * 10^2

Step-by-step explanation:

Given the expression;

(5×10−3)+(6×10−3)2.2×10^4

First we need to do the multiplication first;

= (5×10−3)+(13.2×10−3+4)

= (5×10−3)+(13.2×10^1)

= 0.005 + 132

= 132.005

= 1.32 * 10^2

Hence the equivalent expression is 1.32.0 * 10^2

Answer:

Domain = All Real Numbers

Range = y≤1

Step-by-step explanation:

Since parabolas are continuous, the domain is all real numbers. The range, or y value, is all real numbers less than or equal to 1 (y≤1), since 1 is the vertex.

Answers

Answer:

A) 2.8 m

Step-by-step explanation:

The formula for the volume of a right rectangular prism is:

Volume = Length × breadth × height

We can just put in the values that we know to find the height.

110.1 = 7.8 × 5.1 × height

height = 110.1 ÷ 7.8 ÷ 5.1

height ≈ 2.8 (rounded to nearest tenth)

Thus, the answer is Option A.

Volume of a Rectangular Prism: V = lwh

Step-by-step explanation:

Step 1: Define

l = 7.8 m

w = 5.1 m

V = 110.1 m³

Step 2: Solve for h

Substitute [VRP]:                    110.1 m³ = (7.8 m)(5.1 m)hMultiply:                                  110.1 m³ = (39.78 m²)hIsolate h:                                 2.76772 m = hRewrite:                                   h = 2.76772 mRound:                                     h ≈ 2.8 m

is y=-3x+2 a function? why is it/is it not a function?

Answers

It is a function.

You can try plot the graph of that equation and then plot a vertical line. You will see that the graph will only intercept the vertical line only once. That is a function.

Or you can look at the equation. Functions have the equations that start with "y=". Rather say that if you see "y" only (not y² or y³ just only y) then that is mostly a function.

Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at the start of the trip and asking to join, but they brought no food. By what percent would the time for the trip shorten for the trip if everyone ate their normal portions?

Answers

The number of people increased by 2.

This means as a ratio it is now 6/4 as many as originally planned.

6/4 can be reduced to 3/2.

The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.

This means the length of time the food lasts is reduced by 1/3, which is 33.3%
