20 feet
25 feet

Answer:

I think it would be D 40, 100

Answer:   p = 30  q = 30 (if not touching edge of hexagon but if it is touching edge one of the pairs) then p or q = 120  and p and q = 30

Step 1)  Sum of an interior angle of a polygon = 720 degree where n = 6 as 6 exterior sides =  (n-2) * 180 = (6-2) * 180 = 4 * 180 = 720 degree   Where the measure of each angle of a hexagon = 720/ 6 = 120 degree   Step 2) Then show 3 angle letter names = 180 degree     Step 3) Angle name letters + 2 angle (other two names letters inside within triangle) add up to 180 degree    Step 3) State since triangle name (of all letters within one triangle) is Isosceles   Step 4) Triangle (state same triangle letters with number 2 in front) = 180 - 120 = 60  then state triangle (letter name) / 2 = 30 degrees obviously the 120 and 60 differentiates if not a hexagon to a pentagon if not a hexagon =  (3 *180) / 5 = 108  then due to isosceles (180 - 108)/ 2  = 72/2 = 36 degree for a pentagon or 30 degree each for p + q for a hexagon etc

Fine the area as if it was a full rectangle then subtract the area of the cut out part.

7 x 6 = 42 square yards

5 x 4 = 20 square yards

42 - 20 -= 22 square yards

Answer:

Q13. Pattern: Distance = 4(Time)

Q14. x=14, y=10

Answer:

They are similar using the angle-angle property.

Step-by-step explanation:

Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.

By AA similarity, triangle PQR similar to triangle STU.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

The two given triangles PQR and STU.

Here, ∠P=63° and ∠R=45°

In triangle STU, ∠S=63° and ∠U=45°

Now, ∠P=∠S=63° and ∠R=∠U=45°

Since angles of triangle are congruent

By AA similarity, ΔPQR similar to ΔSTU

Therefore, triangles are similar.

Answer:

24

Step-by-step explanation:

Answer:Thus 30% of 80 is (30/100) x 80 = 24.

The sequence of the terms is -7,-1+5, and +11. A series is a collection of sequences.

A sequence is a collection of items that have been arranged in a logical order, with members appearing either before or after each other.

Given equation ;

[tex]\rm a_n = a_{n-1}+6[/tex]

If,

[tex]\rm a_1 = -13[/tex]

The next term in the sequence is;

[tex]\rm a_2 = a_{2-1}+6 \\\\ \rm a_2 = a_{1}+6 \\\\ a_2 = -13 +6 \\\\ a_2 =-7[/tex]

[tex]\rm a_3 = a_{3-1}+6 \\\\ \rm a_3 = a_{3}+6 \\\\ a_3 = -7 +6 \\\\ a_3 =-1[/tex]

D. -3x + 18

Step-by-step explanation:

3x - 9y = 18

y = 1/3 x - 2  ... x intercept   0 = 1/3x -2        x=6

perpendicular line slope: - 1/(1/3) = -3 and (6,0) 0n the line

equation: (y-0)/(x-6) = -3

y = -3x +18

Step-by-step explanation:

33oz = 100%

1% = 100%/100 = 33/100 = 0.33oz

59 - 33 = 26oz increase

how many % are these 26oz compared to the original 33oz ?

we need to see how often 1% fits into 26oz.

26/0.33 = 78.78787878...%

rounded this means a 79% increase of drinking water.

=======================================================

Explanation:

Use the distance formula to compute the length of each segment. For instance, the distance from point F to point G is the length of segment FG.

I'll show the steps on finding the length of FG

[tex]F = (x_1,y_1) = (-5,10)\\\\G = (x_2,y_2) = (-2,2)[/tex]

[tex]d = \text{distance from F to G}\\\\d = \text{length of segment FG}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-5-(-2))^2+(10-2)^2}\\\\d = \sqrt{(-5+2)^2+(10-2)^2}\\\\d = \sqrt{(-3)^2+(8)^2}\\\\d = \sqrt{9+64}\\\\d = \sqrt{73}\\\\d \approx 8.544\\\\d \approx 8.5\\\\[/tex]

The length of segment FG is approximately 8.5 units. The other side lengths are handled in the same way. As an alternative, you can use the pythagorean theorem.

---------------------

Once you determine all six lengths, note we have the following three pairs of corresponding congruent sides:

Because we have three pairs of equal sides, this means we can use the SSS (side side side) congruence theorem to prove the triangles are congruent. In other words, we have two identical triangles. One triangle is a rotated and reflected copy of the other.

Answer:

138 calories/serving

Step-by-step explanation:

Find the unit rate, the measure of how many calories are in each serving:

621 calories

-------------------- = 138 calories/serving

4.5 servings

The number of calories are in each serving is 138.

Given that, a bag of chips contains 621 calories and serves 4.5 people.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Number of calories in each serving = Total number of calories/Number of servings

= 621/4.5

= 138 calories

Therefore, the number of calories are in each serving is 138.

The common difference is 1.8.

__

The 8th term is found by putting 8 where n is and doing the arithmetic.

  a₈ = 80 -14 = 66

The eighth term is 66.

Answer:

It is already in the simplest form, but you can convert It into many things.

Step-by-step explanation:

Make this into an improper fraction you: 1 x 4 + 1 then put the answer on the numerator and keep the denominator.

Mixed number = 5/4

Decimal = 1.25
