Answer: It's correct because it is the only one with an angle more than 180°

Step-by-step explanation:

D is a right angle, A is an acute angle, as well as B. So not only is C the only one with an obtuse angle and it also has the biggest angle out of the other two angles on the triangle, you can use process of elimination to figure it out as well. Hope this helps, have a good day! :-)

Which value if x makes this proportional true? 14/20=56/x A.x=62 B.x=70 C.x=80 D.x=100

Leya [2.2K]

<h3>Answer: C) x = 80</h3>

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

Work Shown:

Let's cross multiply to get the following

14/20 = 56/x

14*x = 20*56

14x = 1120

x = 1120/14

x = 80

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

As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.

You purchase 26 “parking hours” that you can use over the next month to park your food truck at the fair. Weekday hours costs $2

Oksanka [162]

Answer: 5

Step-by-step explanation:

weekday hours x*2

weekend hours y*10

x+y=26

2x+10y=220

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

x=26-y

2(26-y)+10y=220

52-2y+10y=220

8y=220-52

8y=168

y=168/8

y=21

x=26-21=5

x=5

Answer:

The number that cannot be the largest possible 6-digit number is;

(D) AAABCB

Step-by-step explanation:

From the question, we have;

A, B, and C = Distinct digits, therefore, A ≠ B ≠ C

The number of digits in the number to be formed = 6 digits

The number of 'A' in the number to be formed = 3

The number of 'B' in the number to be formed = 2

The number of 'C' in the number to be formed = 1

We have;

When A > B > C

The largest possible number = AAABBC

When C > A > B

The largest possible number = CAAABB

When B > A > C

The largest possible number = BBAAAC

When A > C > B

The largest possible number = AAACBB

Therefore, given that when A > B > C, the largest possible number = AAABBC, we have;

AAABBC > AAABCB, because B > C, therefore, within the tens and unit of the two 6 digit numbers, we have, BC > CB

∴ AAABBC > AAABCB and <u>AAABCB</u>, cannot be the largest possible 6-digit number

The sum of the interior angles of a polygon is

Crank

Answer:

D) 15

Step-by-step explanation:

The sum of the interior angles of a polygon is given by

$(n - 2) \times 180$

We have that, the sum of the interior angles of a polygon is

26 right angles. We want to find n, the number of sides.

We substitute into the formula to get:

$(n - 2) \times 180 = 26 \times 90$

Divide through by 90

$2(n - 2) = 26$

Divide through by 2

$n - 2 = 13$

$n = 13 + 2$

$n = 15$
