Answer:

Solve: 4 - 2 x 8 + (6 x 2) x 4 + 3^2

Answers

Answer:

42

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

4 - 2 × 8 + (6 × 2) × 4 + 3²

= 4 - (2 × 8) + (6 × 2) × 4 + 3²

= 4 - 16 + 12 × 4 + 9

= (4 - 16) + (12 × 4) + 9

= -12 + 48 + 9

= 45

A small town has two local high schools. High School A currently has 850 students
and is projected to grow by 35 students each year. High School B currently has 700
students and is projected to grow by 60 students each year. Let A represent the
number of students in High School A int years, and let B represent the number of
students in High School B after t years. Write an equation for each situation, in terms
of t, and determine after how many years, t, the number of students in both high
schools would be the same.

Answers

Answer:

For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.

Then [tex]S_A(t) = 850 + 35t[/tex] and [tex]S_B(t) = 700 + 60t[/tex].

After 6 years the number of students in both high schools would be the same.

Step-by-step explanation:

For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.

Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that [tex]S_A(t) = 850 + 35t[/tex].

Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that [tex]S_B(t) = 700 + 60t[/tex].

Setting the two equations equal to each other, we see that [tex]850+35t=700+60t\\850-700=60t-35t\\25t=150\\t=6[/tex]

So after 6 years the number of students in both high schools would be the same.

Rondell covered a table top with 36 square tiles. Each tile measures 8 inches by 8 inches. What is the area of the table top?

Answers

8x8 = 64 sq in per tile

64sq in x 36 tiles = 2,304 square inches

Answer: 2,304 square inches

Step-by-step explanation:

if there are 36 total tiles on the table, that means there are 6 on each side.

If each side meaures 8, then one side of the table is 48, and since the tikes are square, the other side of the table will be the same. 48 x 48=2,304

The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?

Answers

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

(John Komperda)

A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length 2 feet. The height, h, of the sand in the container increases at a rate of approximately 8 inches per minute. Create an equation that models the volume, V, of the sand in the container in terms of h, then use the equation to determine the time at which the volume is 64 cubic feet. Note that the volume of a rectangular prism is V=l×w×h, where l, w, and h are the length, width, and height of the prism.

how to I do Ratios with cross multiplying

Answers

I think if it is not correct i am vary sorry

Answer:

To cross multiply, multiply the numerator from one side with the denominator of the other side and put that product on one side of the equation. Do the same with the other numerator/denominator and put that on the other side. From there, solve for the unknown part.

So your ratio might look like this:

4/6=x/12

6x=12(4)

6x=48

x=8

So in this case 4/6 would equal 8/12.

Bo' sister Anna is 3/4 his age minus 1 year. She is 11 years old.Write an equation to find Bo's age.

Answers

Answer: 16 years

Step-by-step explanation:

Let's Bo's age be represented by x.

Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:

(3/4 × x) - 1 = 11

3/4x - 1 = 11

3/4x = 11 + 1

3/4x = 12

Multiply both side by 4/3

x = 12 × 4/3

x = 16

Bo's age is 16 years

Answers

Answer:

x=1

Step-by-step explanation:

You need to add the Numbers with an x together as if they were racist on each side so you'd have

4x+2 = x+5

Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative

4x-x=-2+5

then add them together

3x= 3

then divide the normal number with the number with the x

x=1

For the next problem you Multiply thr number that are in the paranthases by the number on the outside so

Explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

Multiply to remove 1 decimal places. Here, you multiply top and bottom by 10^1 = 10

7.2/1×10/10=72/10

Find the Greatest Common Factor (GCF) of 72 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
