Steve connected a wire extension that is 3/8 foot long to another wire that is 1/2 foot long. How long is the wire with the extension?

Answers

Answer 1

Answer:

7/8 feet

Step-by-step explanation:

In order to add two frctions you need to make their denominator the same,

3/8 can be kept as it is and we can multiply the top and bottom of 1/2 by 4 in order to ger 4/8. Now it is easier to add together,

3/8 + 4/8= 7/8

What is the x in this equation

14x−8=4

Answers

Answer:

x =  6  / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 =  4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x  / 14  =  12  / 14

x =  6  / 7

which of the following trigonometric expressions are equal? a. sin(theta) b. cos(theta)tan(theta) c. 1/sec(theta) d. csc(theta) (1-cos^2(theta))​

Answers

Answer:

A & B

Step-by-step explanation:

cos(theta)tan(theta) can be expressed as;

cos(theta)tan(theta) = cos(theta) × (sin(theta))/cos(theta).

cos(theta) cancels out to give; sin(theta)

Thus is equivalent to option A

Ms. Peters has 36 red, blue, and green markers. She has an equal number of
each color of marker. She arranges the red markers in 2 equal groups. How
many red markers are in each group?
18
9
6
12

Answers

Answer:

6 markers

Step-by-step explanation:

1) Find the number of red markers

Firstly, we know that Ms. Peters has a total of 36 markers. There are 3 colours within these 36 markers. Because she has an equal number of each colour, divide 36 by 3 to find the number of red markers.

36÷3=12

Therefore, Ms. Peters has 12 red markers.

2) Find the number of red markers in each group

Ms. Peters then divides the red markers into 2 equal groups. Because we now know that there are 12 red markers, divide 12 by 2 to find this number.

12÷2=6

Therefore, there are 6 red markers in each group.

I hope this helps!

12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3

Answers

Answer:

D) 4/3

Step-by-step explanation:

12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3

IF tan Z = 3/4

Since m<Y = 90 degrees

Let the opposite side be XY

YZ be the adjacent side

and XZ is the hypotenuse

Given

tan theta = opp/adj

opp = 3 = XY

adj = 4 = YZ

Get the hypotenuse

hyp^2 = 3^2 + 4^2

hyp^2 = 9 + 16

hyp^2 = 25

hyp = √25

hyp = 5

for tanX;

Side opposite to angle X is YZ

Adjacent side = XY = 3

opposite = YZ = 4

Tan X = YZ/XY

Tan X = 4/3

Hence the prediction of Tan X is 4/3
