A square has a diagonal that measures 18 inches. To the nearest tenth, what is the length of one side
of the square?

Answers

Answer 1

Answer:

18/sqrt(2)

Step-by-step explanation:

Divide the square into two congruent right triangles:

a and b are the sides of the triangle

since we know that a=b

then the right triangle is isosceles

meaning that the theorem of the 45-45-90 triangle is applicable

so then we can say that 18/sqrt(2) = a = b

Jenna saves $2,500 per year in an account that earns 10% interest per year, compounded annually. Jenna will have(A $411,234) (B $425,352) (C $449,739) saved in 30 years. Her account balance is a result of Jenna’s(A annuity payments)(B lump-sum payment) .

Answers

Answer:

The answer is $43623.50

Step-by-step explanation:

This problem is on compound interest.

the expression for compound interest is given as

A=P(1+r)^t

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Given data

P= $2,500

r= 10/100= 0.1

t= 30 years

substituting into the expression for compound interest and solving for A we have

A=2500(1+0.1)^30

A=2500(1.1)^30

A=2500*17.449

A=$43623.50

The final amount is $43623.50

Her account balance is a result of Jenna’s(A annuity payments)

A shop sells matching hats and scarves.The scarves cost 1.5 times as much as the hats.Write two patterns that could represent the cost of 1234 and 5 hats and scarves.List the first 5terms of each pattern.Then explain how to find the cost of 6hats and scarves,using the patterns you wrote u

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Let Cost of hats = h

Cost of scarves = 1.5h

Hence if hats cost $h, then the cost of scarves will be; (1.5 * h)

Using tables :

If the cost of an hat = $2

Hence,

N _____cost of hat(h) ____cost of scarve

1_______2*1 = 2 _________1.5(2) = 3

2______2 *2 = 4 _________1.5(4) = 6

3______2*3 = 6 _________1.5(6) = 9

4 ______ 2*4 = 8 ________1.5(8) = 12

5 ______2 *5=10 ________1.5(10) = 15

Cost of 6 hats and scarve:

Cost of hat:

2 * 6 = $12

1.5h = 1.5(12) = $18

There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have a linear equation in one-variable:

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

0.75(x + 40) = 0.7(x + 20)

75(x + 40) = 70(x + 20)

75x = 70x - 1600

x = -370

Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

A line with points M, H, K intersects a line with points J, H, L at point H. 4 angles are created. Clockwise, from the top, the angles are blank, (x + 15) degrees, blank, (2 x minus 20) degrees. What is mAngleMHJ? 35° 50° 72.5° 92.5°

Answers

Answer:

Step-by-step explanation:

a) sum of angle on the straight line TRW is 180.

Given <TRS = 2x+10

<SRW = x-10

<TRS+<SRW = 180

2x+10+x-10 = 180

3x = 180

x = 180/3

x = 60°

<TRV = 180°-(2x+10)

Substitute x = 60° into the expression

<TRV = 180-(2(60)+10)

<TRV = 180-(120+10)

<TRV = 180-130

<TRV = 50°

2) From the diagram attached <MHJ= <LHK (oppositely directed angle)

Given

<MHJ= x+15

<LHK = 2x-20

Substitute the given data into the formula to get x

x+15= 2x-20

x-2x = -15-20

-x = -35

x = 35°

Next is to get the measure of <MHJ

<MHJ = x+15

<MHJ = 35+15

<MHJ = 50°
