Solve For A Side In Right Triangles

Answers

Answer 1

Answer: x = 4.56

Step-by-step explanation:

Angle A = 20 degrees

x = BC

sin(20) = x/5

multiply 5 on both sides

5sin(20) = x

x = 4.56

Answer 2

Answer:

1.71

Step-by-step explanation:

Cosine = adjacent/hypotenuse

cos 70 = x/5

cos 70 = 0.3420201433

0.3420201433(5) = 1.710100716

x=1.710100716

x=1.71

First, you need to know how much they’re dilated.

To find that out you do:
15/10 = 1.5

So they’re dilated by 1.5cm

To find the value for y you do:
6•1.5 = 9

y = 9

solve the equation 243×=73, where × is the base of the number.

Answers

243x/243 = 73/243
x= 73/243
x= 0.300412

The value of × that satisfies the equation 243× = 73 is approximately 0.6691.

To solve the equation 243× = 73, where × represents the base of the number, we need to determine the value of × that satisfies the equation.

We can start by rewriting the equation as an exponential equation:

243ˣ= 73

To solve for ×, we need to isolate × on one side of the equation. We can do this by taking the logarithm of both sides of the equation. Let's take the logarithm with base 10 (log) for simplicity:

log(243ˣ) = log(73)

Applying the logarithmic property, we can bring down the exponent × as a multiplier:

× * log(243) = log(73)

Now, we can solve for × by dividing both sides of the equation by log(243):

× = log(73) / log(243)

× ≈ 0.6691

Therefore, the value of × that satisfies the equation 243× = 73 is approximately 0.6691.

Which expression shows the quotient of two terms where one of the terms includes the coefficient of 8?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve generally

Required

Quotient of two terms where 1 has a coefficient of 8

The quotient (Q) of a and b can be represented as:

[tex]Q = \frac{a}{b}[/tex]

Where a and b are the terms

For a or b to have a coefficient of 8, then a or b must be

[tex]a\ or\ b = 8x[/tex]

Where x is the variable

So, the quotient can be expressed as any of:

[tex]Q = \frac{8x}{y}[/tex]

[tex]Q = \frac{z}{8i}[/tex]

[tex]Q = \frac{24b}{8c}[/tex]

As long as one of the terms has a coefficient of 8

Write and solve an equation to find the width of the box if its volume is 80 cubic centimeters. Then find its surface area.

Answers

Answer:

L=4.30cm

SA=  110.94cm^2

Step-by-step explanation:

Given data

Volume of box= 80 cm^3

We know that the volume of a box is given as

V= l^3

80=l^3

l= ∛80

l= 4.30cm

also the surface area of a box is given as

SA=2lw+2lh+2hw

SA= 2* 4.30* 4.30+2* 4.30* 4.30+ 2* 4.30* 4.30

SA= 36.98+36.98+36.98

Answer:

.01*.5ˣ

Step-by-step explanation:

we can see that x=0 y= .01

so in our equation

a*bˣ

a=.01

This is throuhg plugging in 0 for x

a*b⁰=.01

a*1=.01

a=.01

Now it's just a matter of finding b

to do this just plug in a value

we know that when x=1 y=.005

.01*b¹=.005

b= .5

So our final equation is :  .01*.5ˣ

A cylinder has a height of 13 centimeters and a radius of 4 centimeters. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answers

Answer:

Volume of a cylinder = 653.12 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

Height, h = 13 cm

Radius, r = 4 cm

π = 3.14

Volume of a cylinder = πr²h

= 3.14 × (4cm)² × 13 cm

= 3.14 × 16 cm² × 13 cm

= 653.12 cm³

Volume of a cylinder = 653.12 cm³

653.45 got it right

2x + 2y = –2 and 3x – 2y = 12 what does x and y equal?

Answers

Answer:

(2,-3)

Step-by-step explanation:

by elemination

2x + 2y = –2

3x – 2y = 12

cross out the 2y and -2y because the cancle each other.

that leaves 2x= -2

and             3x = 12.

simply add/subtract. 2x+3x=5x

                                  -2+12=10.

                                    5x=10

                                    x=2.

now for the y. we have x so all we have to do is plug.

take any equation.   2x + 2y = –2  and plug 2 into the x.

2(2)+ 2y = –2

4+2y= -2

-2-4= -6

2y=-6

y=-3.

put x and y into ordered pairs

(2,-3) and done.

easy peasy.

Answer:

x=2 y= -3

Step-by-step explanation:

2x+2y = -2

x+y = -1 (dividing both sides with 2

x+1 = -y

3x - 2y = 12

3x + (-y)(2) = 12

3x + (x+1)(2) = 12

3x+2x+2=12

5x+2=12

x=2

-y= 1+2
