Answers

Answer 1

Answer:

44m²

Step-by-step explanation:

Area of larger rectangle

= length × breadth

= 8m × 4m

= 32m²

Area of smaller rectangle

= length × breadth

= 4m × 3m

= 12m²

Total area of the figure

= Area of larger rectangle + Area of smaller rectangle

= 32m² + 12m²

= 44m²

11 Alicia buys a car that costs $26610, and she makes a $3140 down payment on it. How much
does she still owe on the car? Give units.

Answers

Answer:

$23,470

Step-by-step explanation:

A down payment is how much you pay upfront for a car. So, how much she still owes will be the difference between the total cost and the down payment. Therefore, subtract $3,140 from $26,610; 26610-3140=23470. Then, since you are talking about money the units are dollars, $.

15) A small rectangular block of land has a perimeter of 100 m and an area of 225 m². Find the dimensions of the block of land.​

Answers

Answer:

45 and 5 are the dimensions of the block of land.​

Step-by-step explanation:

2(x + y) = 100, x + y = 100/2, y = (50 - x)

xy = 225

x (50 — x) = 225

0 = x^2 — 50x + 225

0 = (x — 45) (x -5)

45 and 5 are the roots of the above polynomial, thus they are the sides or dimensions of the block of land.

X/2-7=9

Show your work in details if you can, I have a hard time understanding this.

Answers

I’m not very good at math but here’s my reasoning:
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3

Answer:

Step-by-step explanation:

x/2  - 7 = 9                  Add 7 to both sides

      +7     7

x/2 = 16                        Multiply both sides by 2

2*x/2 = 16*2        

x = 32

You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.

Take a much simpler question

x - 8 = 10        What do you do here? You can't multiply or divide. So add

  +8    8

x    =    18

Now try what you have

2x - 5 = 11                      Add before multiplication or division

    5      5

2x = 16                          Divide by 2

2x/2 = 16/2

x = 8

Given the form of the equation 3x + 2y = 3 and x – 3y = -10. Then determine the result of 3x - y !​

Answers

Answer:

-6

Explanation:

x= -1 and y=3

3x- y

=> 3(-1)-3 = -3-3= -6

Answer:

3x – y = -6

Step-by-step explanation:

To solve on the problem above, you can do it by substitution and elimination of the two equations.

3x + 2y = 3

➡️ 3x + 2.3 = 3

➡️ 3x + 6 = 3

➡️ 3x = -3

➡️ x = -1

➡️ 3x – y = 3(-1) – 3

➡️ = -3 – 3 = -6 ✅

Answers

Answer:

7x-10y=6

Step-by-step explanation:

Firstly, supervise 7x-10y=3 using the coordinates of one from the known points

7*8-10*5=3

6=3 It is not correct, so the equation is uncorect

Find the correct equation

The common equation is y=mx+b

5=8m+b

-9=-12m+b

Both equations are simultaneous.

-9-5= -12m+b- (8m+b)

-14=-20m

m=0.7

b=5-5.6=-0.6

y=0.7x-0.6

0.7x-y=0.6

7x-10y=6- the correct answer

which of the following is equivalent to 7x+5<-2(4x-3)
x>11
-x<1
15x<-11
15x<1

Answers

Answer:

7x+5< -8x+6

=15x<1

The equivalent inequality is 15x<1. Therefore, option D is the correct answer.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is 7x+5<-2(4x-3).

Now, 7x+5<-8x+6

Subtract 5 on both the sides of an inequality, we get

7x<-8x+1

Add 8x on both the sides of an inequality, we get

7x+8x<1

15x<1

Therefore, option D is the correct answer.

A pole that is 2.8 m tall casts a shadow that is 1.46 m long. At the same time, a nearby building casts a shadow that is 50.25 m long. How tall is the building?
Round your answer to the nearest meter.

Answers

Answer:

96 m

Step-by-step explanation:

Create a proportion where x is the height of the building:

[tex]\frac{2.8}{1.46}[/tex] = [tex]\frac{x}{50.25\\}[/tex]

Cross multiply and solve for x:

1.46x = 140.7

x = 96

So, the height of the building is approximately 96 m tall
