Determine whether the forces in the pair are pulling at right angles to each other.For the values a = 2.9 which is a leg of a right triangle, and value c = 4.2, which is the hypotenuse, find the length of the other leg, b, to the nearest tenth.

1.3

Answers

Answer 1
Answer: Given:
right triangle
a = 2.9
c = 4.2

Pythagorean Theorem: a² + b² = c²

missing value of b.

b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0 

The value of b is 3.0

A quarter has a diameter of 2.4 m . what is it's circumference in cm

Answers

First lets convert the diameter to cm,
2.4 m equals 240 cm, that is by multiplying 2.4 times 100 because 1 meter has 100 cm
then we need to know how to calculate the circumference, and that is by multiplying pi (3.14) times the diameter of the circumference, that is:
circumference = pi*diameter = 3.14*240
circumference = 753.6 cm
that is the solution

Put the following equation of a line into slope-intercept form, simplifying all fractions.12x-20y=60

Answers

Answer:

y= (-3/5)x + 3

Step-by-step explanation:

Slope-Intercept form is y = mx + b, where m is the slope and b the y-intercept.

12x-20y=60   Rearrange

20y=60 -12x

20y= -12x + 60

y= (-12/20)x + (60/20)

y= (-3/5)x + 3

1. The measures of two angles are (5x + 24) and (9x - 17). What is the value of xif theseangles are congruent?

Answers

Answer:

x = 41/4

Step-by-step explanation:

If the angles are congruent, then the equation are congruent.

Step 1: Set up equation

5x + 24 = 9x - 17

Step 2: Solve for x

  1. 24 = 4x - 17
  2. 41 = 4x
  3. x = 41/4

Answer:

Slope = 3/2, or 1.5

Step-by-step explanation:

Pick out the lattice points ( points that intersect the graph markings)

I see 2 points, ( 3, 1), and ( 5, 4)

Slope = Δy/xΔ = 4 - 1/5 - 3 = 3/2

Slope is 3/2, or 1.5

lius has 5 over 8 quart of grape juice he pours the same amount in each 5 glasses which equation represents the fraction of a quart of grape juice n that is in each glass

Answers

so we have to divide 5/8 into 5 equal segments.

5        5
--  ÷  ---
8       1

in order to divide fractions we need to flip the second fraction and change the sign from a divition sign to a multiplication sign

5      1       5
-- × --- =   ---
8      5      40

now we just simplify  5/40 is equal to 1/8

each glass gets 1/8 of a quart
