Answer:

(3+2)*5 ---------> 5 squared

5 cubed --------> 125

10 squared divided by 2 ---------> 50

Step-by-step explanation:

First of all, you don't need to beg. It's all right. You got this!

This question is asking us to simplify what is on the left and match it to the right.

(3+2)*5

5*5= 25

5 squared is 5*5 which is equal to 25

5 cubed is 5*5*5 which is equal to 125

10 squared divided by 2

10*10= 100

100/2= 50

Answer:

[tex]a = \frac{u + 3}{-3}[/tex]

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 3 to both sides of the equation:

u = -3a - 3

u (+3) = -3a - 3 (+3)

u + 3 = -3a

Next, divide -3 from both sides of the equation:

(u + 3)/-3 = (-3a)/-3

a = (u + 3)/-3

[tex]a = \frac{u + 3}{-3}[/tex]  is your answer.

11-0.9=10.1

The total amount of money spent will be $10.1.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that you receive $50 for your birthday. You buy a book for $14.95 and a baseball cap for $24.95.

50-14=36

36-24=12

12-1=11

11-0.9 = $10.1

Therefore, the total amount of money spent will be $10.1.

Answer:

B. Billie's solution is right

Answer:

Let's suppose that the hole is at y = 0m, where x is the time variable.

we know that:

The vertex is (-1s, 8m).

(i suppose x in seconds and y in meters)

At x = 1s, the ball reaches the hole, so we also have the point:

(1s, 0m).

Remember that the vertex of a quadratic equation y = a*x^2 + b*x + c is at:

x = -b/2a,

then we have:

-1 = -b/2a.

Then we have tree equations:

8m = a*(-1s)^2 + b*-1s + c

0m = a*(1s)^2 + b*1s + c

-1s = -b/2a.

First we should isolate one variable in the third equation, and then replace it in one of the other two:

1s*2a = b.

So we can replace b in the first two equations bi 1s*2a.

8m = a*1s^2 - 1s*2a*1s + c

0m = a*1s^2 + 1s*2a*1s + c

We can simplify both equations and get:

8m = a*( 1s^2 - 2s^2) + c = -a*1s^2 + c.

0m = a*(1s^2 + 2s^2) + c = a*3s^2 + c.

Easily we can isolate c in the second equation and then replace it into the first equation:

c = -a*3s^2

The first equation becomes:

8m = -a*1s^2 - a*3s^2 = -a*4s^2

a = 8m/-4s^2 = -2m/s^2.

Now with a, we can find the values of c and b.

c = -a*3s^2 = -(-2m/s^2)*3s^2 = 6m.

b = 1s*2a = 1s*(-2m/s^2) = -2m/s.

Then the equation is:

y = (-2m/s^2)*t^2 + (-2m/s)*t + 6m

Have a nice day! :D

Step-by-step explanation:

Answer:

20 riders can ride per minute.

Step-by-step explanation:

The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.

The reasoning behind this is:

There are 60 minutes in an hour.

If the park ride lasts a minute, then the ride can have 60 rides per hour.

The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.

1200 ÷ 60 = 20.

First, let's define variables:

A = adults

C = children

Okay, now that's done, time to set up the two equations required to solve:

10a + 7c = 6549

a + c = 783

One way you can solve this is to set up the second equation to isolate a variable. For example,

a = -c + 783

Using this, we can plug it into the first equation and solve for c.

10(-c+783) + 7c = 6549

-3c = -1281

c = 427

Now, use the value of 427and plug it in either equation to solve for a.

a + 427 = 783

a = 356

356 adult tickets were sold, and 427 children tickets were sold.

20/24 = [tex]\frac{20}{24}[/tex]

Make sure the fraction is correct, by adding.

Answer:

56 baseball's

Step-by-step explanation:

The number of baseballs were pitched to Chad in 8 minutes is 56.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Given that, the pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes.

Number of pitches hit in 1 minute = 35/5

= 7

Chad practiced hitting for 8 minutes.

So, the number of baseballs were pitched = 7×8

= 56

Hence, the number of baseballs were pitched to Chad in 8 minutes is 56.

Answer:

x=160°, y= 62°

Hope this helps

Answer:

∠X = 160°, ∠Y = 62°

Step-by-step explanation:

∠ABD = ∠FDC = 20° [ DF║AB ]

∠X = 180° - ∠FDC

∠X = 180° - 20° = 160°

∠FCD = ∠BCA = 98°        

∠Y = ∠CAB [ DF║AB]

∠BCA+∠CAB+∠ABC = 180°

98°+∠CAB+20° = 180°

∠CAB = 180° - 118° = 62° = ∠Y
