Answer:

A and C I believe

Step-by-step explanation:

Because when you take 7.429 another nine rounds the 2 and it is higher than 5 so it would make that 7.43 and for C 7.433 the second 3 is lower than 5 so it doesnt change anything, since 5 and above give it a shove and 4 and below let it go, so I believe its A and C

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)

Step-by-step explanation:

A Rational number is one that can be expressed as a fraction where the denominator is not zero. The above decimal can be expressed as a fraction in the form : ¹⁸⁶/₁₀₀₀

The decimal is also a terminating decimal which describes a decimal number that has a certain number of digits after the decimal point. In other words, the digits after the decimal point do not go on forever. 0.186 has three digits after the decimal meaning it does not go on forever.

Answer:

I think there is an error in the question, I assume it reads:

4x+2y=20

x+3y=50

If not, please make appropriate corrections to the question.

Answer: x=-4, y=18

Step-by-step explanation:

4x+2y=20

Simplify, divide by two,

2x+y=10.....................(1)

x+3y=50....................(2)

Multiply (2) by 2

2x+6y=100 ....................(2a)

Subtract (1) from (2a)

2x+6y - (2x+y) = 100 - 10

5y = 90

y=18..............................(3)

Substitute (3) into (1)

2x+(18)=10

2x = 10-18 =-8

x=-4  ............................(4)

Substitute (3) and (4) into (1) for verification

2x+y = 2(-4)+18 = 18-10 = 10   checks.

Substitute (3) and (4) into (2) for verification

x+3y=-4+3(18) = -4+54 = 50  checks.

Have a nice day!

The word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is 2 1 / 2 = w + 1 / 2

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Therefore, the word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is as follows;

The sum of the number w and 1/2 is w + 1 / 2.

Then, the word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is

Step-by-step explanation:

(6,4) and (2,10)

Slope:

m=(y2-y1)/(x2-x1)

m=(10-4)/(2-6)

m=6/(-4)

m =  -3/2

Answer:

To find the absolute value of an negative number, just take away the negative sign

The absolute value of a number can NEVER be negative

Step-by-step explanation:

For example, to find the absolute value of -22, it would be 22, since it is 22 points away from zero. To find the absolute value of -99.9, it would be 99.9.

A negative number is NOT always the absolute value of a number.

For example, the absolute value of 34 is, 34. If you plot it on a number line, it is 34 points away from zero, therefore proving a negative number is NOT always the absolute value of a number.

The absolute value of a number can NEVER be negative.

Answer:

The absolute value of a number is always POSITIVE! To find the absolute value, all you need to do is take away the negative sign!

[tex]5.77\ \text{m}[/tex]

[tex]11.54\ \text{m}[/tex]

Step-by-step explanation:

p = Height of pole

h = Length of role

b = Distance between the bottom of the rope and bottom of the pole = 10 m

[tex]\theta[/tex] = Angle between the rope and the ground = [tex]30^{\circ}[/tex]

[tex]\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}[/tex]

The length of the rope is [tex]5.77\ \text{m}[/tex]

[tex]\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}[/tex]

The length of the pole is [tex]11.54\ \text{m}[/tex]

The time it will take for the coin to hit the ground is 5 seconds for the given function.

Displacement and distance are terms used to describe how an object or person moves, but they have different meanings.

No matter where anything starts or ends, distance describes how much ground it has travelled. It is a scalar quantity with units like metres, kilometers, miles, etc. for measurement.

On the other hand, displacement describes a change in an object's or a person's location from their original position to their end position, including direction. Since it has both magnitude (the distance) and direction, it is a vector quantity. Displacement can be positive or negative depending on the direction of movement and is measured in units like metres, kilometers, miles, etc.

The given equation is  y=-5t² +125.

When the coin hits the ground the value of y = 0 thus,

y = -5t² + 125

0 = -5t² + 125

5t² = 125

t² = 25

t = ±5

Hence, the time it will take for the coin to hit the ground is 5 seconds.

Answer:

$ 600

Step-by-step explanation:

From the question given above, the following data were obtained:

Principal (P) = $ 3000

Time (T) = 5 years

Rate (R) = 4%

Interest (I) =?

The total interest he will receive can be obtained as follow:

I = PTR/100

I = 3000 × 5 × 4 / 100

I = 60000 / 100

I = $ 600

Thus, the total interest he will receive is $ 600

The amount of $600 received by Prince Charming on the investment of $3000 for 5 years.

Prince Charming invests $3000, thus the principal amount is $3000.

He invest the same amount for 5 years, thus time we have to paid on this principal is 5 years.

The rate for which the principal amount increase is 4 %.

The formulated way to represent the simple interest (I) after passing t years of time, at a rate of r % and having a principal amount of P is mentioned below.

[tex]I=\dfrac{P \times r \times t}{100}[/tex]

Substitute the given values in the above formula to calculate simple interest.

[tex]\begin{aligned}I&=\dfrac{3000 \times 4 \times 5}{100}\\&=600 \end{aligned}[/tex]

Thus, the amount of $600 received by Prince Charming on the investment of $3000 for 5 years.

Answer:-29+26

Step-by-step explanation:

f(x)=2x^2-8x from x=2 to x=5. Simplify your answer as much.

We need to find [f(b) - f(a)]/(b - a).

Let a = 2

Let b = 5

f(2) = 2(2)^2 - 8(2)

f(2) = 8 - 16

f(2) = -8

We now find f(5).

f(5) = 2(5)^2 - 8(5)

f(5) = 50 - 40

f(5) = 40

[f(5) - f(2)]/(5 - 2)

(40 - (-8))/(3)

(40 + 8)/3

48/3 = 16

The average rate of change is 16.
