Answer:

Step-by-step explanation:

1). By applying cosine rule in the given triangle,

   cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

   cos(x°) = [tex]\frac{6}{8}[/tex]

   x = [tex]\text{cos}^{-1}(\frac{3}{4} )[/tex]

   x = 41.41°

2). By applying cosine rule in the given triangle,

   cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

   cos(x°) = [tex]\frac{4}{5}[/tex]

   x = [tex]\text{cos}^{-1}(0.8)[/tex]

   x = 36.87°

3). By applying cosine rule in the given triangle,

   cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

   cos(x°) = [tex]\frac{51}{85}[/tex]

   x = [tex]\text{cos}^{-1}(0.6)[/tex]

   x = 53.13°

Answer:

x+7

Step-by-step explanation:

Remove Parentheses

Collect like terms

Calculate

Answer: x+7

Step-by-step explanation: distribute the -2 first

3x - 2x + 8 - 1

simplify (combine like terms )

3x-2x= x

8-1= 7

x+7  

Hope this helps (^_^)

Answer:

b) Take the current height, and add up 15.

c) y = 80x + 15

where y is the height of the water in the pool, in centimeters

where x is the time since the hose is in the pool, in hours

d) 180 = 80x + 15

165 = 80x

x = 165/80 = 2.0625 hours, which is also 2 hours and 3 minutes.

Answer:

X = 11

Step-by-step explanation:

since the angles are supplementary that means their sum is 180

[tex]5x + 15 + 10x = 180 \\ 15x + 15 = 180 \\ 15x = 180 - 15 \\ 15x = 165 \\ x = 165 \div 15 \\ x = 11[/tex]

Answer:

  CPCTC

Step-by-step explanation:

The applicable reason for statement 4 is "Corresponding Parts of Congruent Triangles are Congruent (CPCTC)".

The reason shown in your problem statement is applicable only within one triangle. The segments of interest are in two different triangles.

Step-by-step explanation:

I think it's wrongly labelled

but lemme adjust it and get you back on track

this is a quadrilateral which angles sum upto 360°.

this hold when <D=84°,<N=74° <M=82 and <L=3x+20

84+74+82+3x+20=360

3x+260=360

3x=100

x=100/3

x=33. 3°

Answer:

4.16 in^3

Step-by-step explanation:

Given data

Volume of sphere= 4/3πr^3

Radius=  1 inch radius

Substitute

Volume of sphere= 4/3*3.14*1^3

Volume of sphere= 4/3*3.14*1

Volume of sphere= 4*1.04

Volume of sphere= 4.16 in^3

Answer:

Step-by-step explanation:

Let’s find the area of the circle.

A = 3.14(7)^2 = 153.86

Now the area of the square:

14•14=196

Now we find the area of the shaded region:

196 - 153.86 = 42.14

the shaded region is 42.14 cm

Answer:

(y-x=1.75)×2

2y-2x=3.5

2y-2x+4x-2y=3.5+4

2x. =7.5

X=3.75

y-x=1.75,

y. =1.75+3.75

y=5.5

Answer:

(-0.283, -0.733)

Step-by-step explanation:

There are various ways in which to approximate the solution.  One is to use a graphing calculator and graph the two functions separately, then determine the point of intersection.  The first function has a parabolic graph that opens down, whereas the second function has an exponential graph which heads downward as x increases.

At first try I found that the two graphs intersect in Quadrant III, at approximately (-1/2, -3/4).

Next I used my calculator's CALC tools, specifically that which finds the coordinates of the intersection of two graphs, ending up with these coordinates:  (-0.283, -0.733).  These coordinates are to the nearest thousandths.

If and when you take Calculus, you'll learn Newton's Method for Finding Roots, which doesn't require a graphing calculator.

Answer: Order from Least to Greatest

-1/8 < 0.33 < 3/8 < 75% < 1 5/8

Step-by-step explanation:

To compare and order fractions we must first convert all integers, mixed numbers (mixed fractions) and fractions into values that we can compare. We do this by first converting all terms into fractions, finding the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.
