Answer:

Use the "find vertically opposite angle" method.

a = 80°

To find the other angles:

Since the angles equal up to 360 which makes a full circle shape...

360 - 80 - 80 = 200 (B and C)

200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)

b = 100°

c = 100°

C. 42

because if you divide 26.2 divided by 5 = 5.24 then you times it by 8 and you will get 41.92 and you will round it to get 42

The figures show the dimensions of a tennis court and a basketball court given in terms of the width in feet of the tennis court

Sholpan [36]

Answer:

a. Perimeter of the tennis court = 6x + 12

Perimeter of the Basketball court = 7x + 36

b. x + 24

c. Length of the tennis court = 78 feet

Width of the tennis court = 36 feet

Length of the Basketball court = 94 feet

Width of the Basketball court = 50 feet

Step-by-step explanation:

a. Perimeter of the rectangle = 2(length + width)

So, perimeter of the tennis court = 2[(2x + 6) + x]

= 2(3x + 6)

= 6x + 12

Perimeter of the Basketball court = 2[(3x - 14)+( $\frac{1}{2}$ x + 32)]

= 6x - 28 + x + 64

= 7x + 36

b. Perimeter of the Basketball court - perimeter of the tennis court

= (7x + 36) - (6x + 12)

= 7x + 36 - 6x - 12

= x + 24

So, perimeter of the basketball court is x + 24 feet greater than that of the tennis court

c. It is given that the width of the tennis court = 36 feet

But, from the figure,

width of the tennis court = x

So, x = 36

Therefore, length of the tennis court = 2x + 6

= 2(36) + 6

= 72 + 6

= 78 feet

Width of the tennis court = x = 36 feet

Length of the basketball court = 3x - 14

= 3(36) - 14

= 108 - 14

= 94 feet

Width of the basketball court = $\frac{1}{2} x+32$

$=\frac{1}{2} (36)+32$

= 18 + 32

= 50 feet

Norma-Jean [14]

Answer:

c. Independent measures; Factorial (two-way) ANOVA

Step-by-step explanation:

The answer to this question is the independent measures one way ANOVA. This is as we have these conditions light on or off and cold or warm room. Now we have to check how these factors are able to affect the amount of food pellets eat whenever they are in these experimental conditions.

option c is the correst answer. A factorial or two way anova is one with more than one factor or explanatory variable.
