Answer:

7. 45

8. 8

Step-by-step explanation:

The incenter is equidistant from the sides of the triangle. Here, you're given two of the radius measures as expressions in x, and you're asked to find the third. They are all the same, so you can equate and evaluate the expressions.

7. 5x = 3x +18

2x = 18 . . . . . . subtract 3x

x = 9

WR = 3x +18 = 3(9) +18 = 45

QW = 45

8. 15x -37 = 7x -13

8x = 24 . . . . . . . . . . add 37-7x

x = 3

DW = 7x -13 = 7(3) -13 = 8

WE = 8

Sin^22x - 2cos2x + 2=0

zhuklara [117]

Answer:

x=πn, n∈Z

Step-by-step explanation:

if sin²2x=1-cos²2x, then

1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;

$\left[\begin{array}{cc}cos2x+3=0\\cos2x-1=0\\\end{array} \ \ \left[\begin{array}{cc}x \ 'does-not-exist'\\cos2x=1\\\end{array} \ \ 2x=2\pi n, n=Z \ x=\pi n, n=Z$

Sam travel 20 miles in three hours. Sam walked part of the distance at a speed of 4 mph. Sam rode his bicycle for the remaining

enot [183]

Answer:

Sam sokey 0.5 hours biking and 3.5 hours walking

Step-by-step explanation:

Here, we want to know the number of hours spent walking and biking

Mathematically; distance = speed * time

Let the number of hours spent walking be x and the number of hours spent biking be y

Mathematically;

x + y = 3 •••(i)

distance spent walking = 4 * x = 4x miles

distance spent biking = 12 * y = 12y miles

4x + 12y = 20

divide through by 2

2x + 6y = 10 ••••••(ii)

From i , x = 4-y

Substitute this into ii

2(4-y) + 6y = 10

8 - 2y + 6y = 10

8 + 4y = 10

4y = 10-8

4y = 2

y = 2/4 = 0.5 hours

The number of hours spent walking = 4-0.5 = 3.5 hours

mezya [45]

Answer:

Medium apple < Large hard boiled egg < raisins < cheddar cheese

Step-by-step explanation:

1. Cubic inch cheddar cheese ;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 69 / 17 = 4.0588cal/g

approximately 4.1cal/g

2. Large hard boiled egg;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 78 / 50 = 1.56cal/g, approximately 1.6cal/g.

3. Medium apple;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 72 / 138 = 0.52cal/g

4. Raisins;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 129 / 43 = 3cal/g

The foods with the lowest density to the highest is,

Medium apple < Large hard boiled egg < raisins < cheddar cheese
