In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot

Answers

Answer 1

Answer:

[tex]CD = 4.4ft[/tex]

Step-by-step explanation:

Given

[tex]DE = 12[/tex]

[tex]\angle C = 70^\circ[/tex]

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

[tex]tan(70) = \frac{DE}{CD}[/tex]

Substitute 12 for DE

[tex]tan(70) = \frac{12}{CD}[/tex]

Make CD the subject

[tex]CD = \frac{12}{tan(70)}[/tex]

[tex]CD = \frac{12}{2.7475}[/tex]

[tex]CD = 4.4ft[/tex] --- approximated

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.

Answers

Answer:

ok let me try this again

To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

ok this isn’t my answer i found it on quora but it answers ur question u have

We can write a system to solve this problem

Let x= the radius of Circle A

Let y=the diameter of Circle B

x=2y-3

2x+y=49

since we are trying to find the area and the circumference of circle A, we only have to find what x is

x=2y-3 → y=1/2x+3/2

next, we plug in 1/2x+3/2 for y:

2x+1/2x+3/2=49

we can then multiply all the numbers by 2 to get rid of the fractions:

4x+x+3=98

5x+3=98

5x=95

x=19

Circle A radius=19ft

Finally, we solve for the area and circumference:

Area:

A=pi*r^2

A=3.14*19^2

A=1133.54 feet^2

Circumference:

C=2*pi*r

C=2*3.14*19

C=119.32 feet

Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.

Answers

Answer:

radius = 6 inches

Step-by-step explanation:

37.68/3.14 = 12 = diameter

radius = 12/2 = 6 inches

Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6

Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04

Answer:
The area of the circle is 113.04 square units

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!

Answers

Answer:

NF = 25

Step-by-step explanation:

Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.

This means that:

KF/ZF = NF/LF

KF = x + 3

ZF = 4

NF = 15 + x + 3 = x + 18

LF = x + 3

Plug in the values into the equation

(x + 3)/4 = (x + 18)/(x + 3)

Cross multiply

(x + 3)(x + 3) = (x + 18)(4)

x² + 3x + 3x + 9 = 4x + 72

x² + 6x + 9 = 4x + 72

x² + 6x + 9 - 4x - 72 = 0

x² + 2x - 63 = 0

Factorize to find x

x² + 9x - 7x - 63 = 0

x(x + 9) -7(x + 9) = 0

(x + 9)(x - 7) = 0

x + 9 = 0 or x - 7 = 0

x = -9 or x = 7

We'd use the positive value of x, which is 7.

Therefore, x = 7.

✅NF = 15 + (x + 3)

Plug in the value of x

NF = 15 + (7 + 3) = 15 + 10

NF = 25

Which equation has infinitely many solutions?

A. 6x + 5 = 6x + 7
B. 6x + 7 = 5x + 7
C. 3(x + 2) – 1 = 3x + 1
D. 4(x + 1) – 3 = 4x + 1

Answers

For C and D do distributive
3x + 6 - 1 = 3x + 1
4x + 4 - 3 = 4x + 1
Only D is true

The solution is D
