The perimeter of a rectangle is 180 meters. If the length of the rectangle is 20 meters more than the width, what are the dimensions of the rectangle?

Answers

Answer 1

Let one side be x, the other side is x + 20.

The perimeter of a rectangle = 2(L+W)

Therefore,

180m = 2(x + x + 20)
180m = 2(2x + 20)
180m = 4x + 40
4x + 40 = 180m
4x = 180 - 40
4x = 140
x = 140/4 = 35

One side is 35 so the other side is 55

Let's check our answer

2(35 + 55)

How to illustrate the information?

It should be noted that a cube had 6 equal faces. In this case, a cube with 2000 interlocking faces can't be constructed with equal number of faces.

In this case, the sides will be:

∠ABC and ∠DEF are complementary. If m∠ABC = (2x+4)∘ and m∠DEF = (3x−5)∘, find the measure of each angle.

m∠ABC =

m∠DEF =

Answers

The measure of each angle are m∠ABC =  40.4 and m∠DEF =  49.6

How to determine the measure of each angle?

The given parameters are

m∠ABC = (2x+4)∘ and m∠DEF = (3x−5)∘,

Complementary angles add up to 90 degrees

So, we have

2x + 4 + 3x - 5 = 90

Evaluate the like terms

5x = 91

Divide by 5

x = 18.2

Substitute x = 18.2 in m∠ABC = (2x+4)∘ and m∠DEF = (3x−5)∘,

m∠ABC = (2 x 18.2 + 4) = 40.4

m∠DEF = (3 x 18.2 − 5)∘ = 49.6

Hence, the measure of each angle are m∠ABC =  40.4 and m∠DEF =  49.6

An executive invests 28,000 some at 7% and the rest at 4% annual interest if he receives an annual return of $1,570 how much is invested at each rate

Answers

we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.

We are given that:

the total amount invested is = $ 28,000

Let the amount invested at 7 % interest rate be x

Amount invested at 4 % interest rate = 28,000 - x

Interest received at the end of year = $ 1570

ATQ:

7 % x + 4 % ( 28,000 - x) = 1570

7 x + 4 (28,000 - x) = 157000

7 x + 112,000 - 4 x = 157,000

3 x = 157,000 - 112,000

3 x = 45,000

x = 45,000 / 3

x = 15,000

Amount invested at 7 % interest rate =  x = $ 15,000

Amount invested at 4 % interest rate = 28,000 - x = $ 13,000

Monica has a goal to complete a triathlon. The race consists of a 2.4-mile swim, a 112-mile bike ride, and a 26.2-mile run. In training, Monica can swim at an average pace of 1.8mph. She rides her bike at an average of 19.2mph and runs at 4.8mph. Estimate how long it will take her to complete the triathlon.

Answers

Taking into account the definition of speed, Monica will complete the triathlon in 12.62 hours.

Definition of speed

Speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:

speed= distance traveled÷ time

Time to complete the triathlon

In this case, you know

Swim:speed= 1.8 mphdistance traveled= 2.4 milesRide a bikespeed= 19.2 mphdistance traveled= 112 milesRun:speed= 4.8 mphdistance traveled= 26.2 miles

Replacing these values ​​in the speed definition:

Swim: 1.8 mph= 2.4 miles÷ time to swimRide a bike: 19.2 mph= 112 miles÷ time to ride a bikeRun: 4.8 mph= 26.2 miles÷ time to run

Solving:

Swim: 1.8 mph×time to swim= 2.4 miles

time to swim= 2.4 miles÷ 1.8 mph

time to swim= 1.33 h

Ride a bike: 19.2 mph× time to ride a bike = 112 miles

time to ride a bike= 112 miles÷ 19.2 mph

time to ride a bike=5.83 h

Run: 4.8 mph× time to run= 26.2 miles

time tu run= 26.2 miles÷ 4.8 mph

time to run= 5.46 h

The time to complete the triathlon is the sum of each of the stages:

Total time= time to swim + time to ride a bike + time to run

Total time= 1.33 h + 5.83 h + 5.46 h

Total time= 12.62 h

In summary, Monica will complete the triathlon in 12.62 hours.

Answer:

Step-by-step explanation:

2b + 10 = 3b - 6 + 23

10 + 6 -23 = 3b - 2b

-7 = b

Answer:

b = -7

Step-by-step explanation:

[tex]2(b+5) = 3(b-2) + 23[/tex]

for the left side of the equation: [tex]2*b + 2*5 = 2b + 10[/tex]

for the right side of the equation: [tex]3*b + 3*-2 = 3b - 6 + 23 = 3b + 17[/tex]

[tex]2b + 10 = 3b + 17[/tex]

to isolate b, subtract 2b from both sides

[tex]10 = b + 17[/tex]

subtract 17 from both sides

What is the line of symmetry for the parabola whose equation is y=x²-12x + 7?
Ox=12
Ox=6
Ox=-6

Answers

Answer:

x = 6

Explanation:

completing square:

[tex]y=x^2-12x+7[/tex]

[tex]y=(x^2-12x)+7[/tex]

[tex]y=(x-6)^2+7-(-6)^2[/tex]

[tex]y=(x-6)^2+7-36[/tex]

[tex]y=(x-6)^2-29[/tex]

Comparing with quadratic equation [tex]y=ax^2 + bx+c[/tex], in vertex form where [tex]y = a(x-h)^2+k[/tex]. In this x - h = 0, x = h defines the symmetry of equation.

So here the symmetry for parabola:

x - 6 = 0

x = 6

Answer:

x = 6

Step-by-step explanation:

The axis of symmetry of a parabola is the x-value of its vertex.

For a quadratic function in the form  [tex]y=ax^2+bx+c[/tex], the x-value of the vertex is:

[tex]x=-\dfrac{b}{2a}[/tex]

Given function:

[tex]y=x^2-12x+7[/tex]

Therefore:

[tex]a=1, \quad b=-12, \quad c=7[/tex]

So the axis of symmetry of the given quadratic function is:

[tex]\implies x=-\dfrac{b}{2a}=-\dfrac{-12}{2(1)}=\dfrac{12}{2}=6[/tex]

Answers

Answer:

(A) is correct.

Step-by-step explanation:

As we know,

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

From the first graph:

The line goes through the points:

(-2, 2) and (2, 1)

y - 1 = (1-2)/(2+2)[x -2]

y - 1 = (-1/4)[x -2]

y = -x/4 + 1/2 + 1

y = -x/4 + 3/2

The constant additive rate of change = -1/4

Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.
