Answer:

Step-by-step explanation:

Because of all the variables in the side lengths, we don't have enough information to use side-angle-side similarity.

We do have two angles of one triangle congruent to two corresponding angles of the other triangle, so we can use angle-angle similarity.

Sides AE and AD are corresponding sides. Sides AC and AB are corresponding.

(Help this is due today)

Answers

Answer: y= -17

Step-by-step explanation:

y= 1 - 2x

so when x=9,

y= 1 - 2(9)=1 - 18= -17

Answer:

y=-17

Step-by-step explanation:

y= 1-2x

since x=9, we substitute the x for 9

y= 1-2(9)

then we multiply 2 with 9

y= 1-18

y=-17

3. The time taken for a water heater to boil water is inversely proportional to the
power of the water heater. When the power is 2000 Watts it takes 240 seconds to
boil the water. Find the time it takes to boil water when the power is reduced to
1000 Watts.
I

Answers

Answer:

t = 480 seconds

Step-by-step explanation:

Let

Time taken for a water heater to boil water = t

power of the water heater = p

Constant of proportionality = k

t = k/p

240 = k/2000

Cross product

240 * 2000 = k

k = 480,000

Find the time it takes to boil water when the power is reduced to 1000 Watts.

t = k/p

= 480,000/1000

= 480

t = 480 seconds

t = 480 seconds when p = 1000 watts

Given the side length, determine whether the triangle is acute, right, obtuse or not a triangle.

10, 23, 41

A. Acute
B. Right
C. Obtuse
D. Not a triangle

Answers

Since 41 is greater than the sum of the other two sides this is not a triangle.

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 6 cm, 8 cm, 9 cm, and 13 cm.

A. Knowing that 6^2 + 8^2 = 10^2, draw the 6 cm side and then the 8 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.

B. Knowing that 6^2 + 8^2 > 9^2, draw the 6 cm side and then the 8 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.

C. Knowing that 8^2 + 9^2 does not equal 10^2, draw the 8 cm side, then the 9 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.

D. Knowing that 6^2 + 8^2 = 10^2, draw any two of the side with a right angle between them. The third side will fit to form a right triangle.

A certain college enrolled 29,000. It was reported 54 percent were female and 46 percent were male. In addition 61 percent were over the age of 25. How many students were in each category if 30 percent of those over the age if 25 were male

Answers

Answer:

Step-by-step explanation:

Total number of students = 29000

Number of female = 54% of 29000

54/100 x 29000 = 15660 students

Number of male = 46% of 2900

46/100 x 29000= 13340 students

61% of 29000 are over 25 years

61% of 29000= 61/100 x 29000

= 17690 students

Of the pupils over the age of 25, 30% are male

30% of 17690 students are male

30/100 x 7690 =5307 students

The number of females over the age of 25 = 17690 -5307

17690 - 5307 = 12383 female students.

Four positive whole numbers add up to 96
One of the numbers is a multiple of 19
The other three numbers are equal.
What are the four

Answers

Multiple of 19: 57
Other 3 numbers are 13

Other four Positive whole number is 13

What is whole number?

The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.

According to the question

First, we consider that if we add together three equal numbers, the result must be a multiple of three. For example, 7 + 7 + 7 = 21, or 11 + 11 + 11 = 33.

Algebraically, we'd say that n + n + n = 3n.

So this means that if we subtract the first number (the one that's a multiple of 19) from 97, we will have a result that is a multiple of 3.

What could the first number be? 19, 38, 57 or 76 . Any other value is larger than the sum of 7, which is not possible if all the integers are non-negative.

Based on this, we can find all possible sums of the other four numbers, by subtracting each of the numbers above from 96:

96 - 19 = 77

96 - 38 = 58

96 - 57 = 39

96 - 76 = 20

Remember what I said earlier? The other four numbers must add to a multiple of 3. The only one of those sums above that is a multiple of 3 is 39. Therefore, we conclude that the first number is 57, and the other four numbers are each 13 (because 39 / 3 = 13).

Hence, other four number is 13
