Answers

Answer 1

Answer:

Answer: 24 cm

Step-by-step explanation:

33 + 23 + x= 180

56 + x = 180

56-56 +x = 180-56

x = 24 cm

on a test, 1 point is given for each correct answer and 1 point is deducted for each incorrect answer. On the test Harold answered 34 items correctly and 6 items incorrectly. What two numbers can be used to find Harold's total score

Answers

Forgive me if I'm wrong, but here goes:

On Harold's test, he scores 34 points for his correct answers, and -6 points for incorrect answers. He would have gotten 28 points, but that's not the question.

34 is the first number, and I believe the next one is -6.
6 is negative because 1 point is deducted for each incorrect answer, which also means 1 point is subtracted for every incorrect answer. Because the question is asking for numbers and not an equation or expression, the subtraction is expressed as a negative symbol, hence negative six.

Well, when you match up the angles, you would see that <T is congruent to <W
So, The answer would have to be B. 99
(they are the same shape, just one is turned around, and smaller, but they have the same angle measures.)
~Hope i helped! :)

The answer will be B.99 because it is the same as t and p is 4 to short in degrees

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards. What is the value of x?

Answers

Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².

Given

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.

a² (24) + β² ( x ) = c² (74)

Calculations

c² = α² + β²

74² = 24²+ β²

5476 = 576 + β²

5476 - 576 = β²

4900 = β²

→√4900

β = 70 yards

70 = 10x

x = 70÷10 = 7 yards

The second leg = 7 yards

Suppose a population has a doubling time of 25 years. By what factor will it grow in 25 years? 50 years? In 100 years?

Answers

Answer:

2,4, and 8.

Step-by-step explanation:

If the population has a doubling time of 25 years, that means that in 25 years the population will double. So for 25 years, the factor will be 2. For 50 years, the factor would be 2x2, which is 4. For 100 years, it is 4x2 which is a scale factor of 8.
