A-total of a ice cream sales in amount of births in a city

b-total amount of ice cream sales in amount of ice cream cones used

c-total amount of ice cream sales in temperature outside

d-total amount of ice cream sales in amount of precipitation outside

Answers

Step-by-step explanation:

A because the amount of ice cream sales doesn't relate to the number of births in a city.

B works because amount of ice cream sales can relate to money. Both C and D work because temperature could affect when people want to buy ice cream. (people most likely won't buy ice cream in the winter but most likely will in the summer)

What is the measure of ZA?

Select the best answer from the choices provided.
A. 35
B. 55°
С.70°
D.110°

Answers

Answer:

55°

Step-by-step explanation:

Since two of the sides are the same length, that means ∠A and ∠B are the same.

All angles of a triangle add up to 180°

180 - 70 = 110

To find ∠A, we just divide 110 by 2

110 ÷ 2 = 55

Both ∠A and ∠B are 55°

Answer:

B. 55°

Step-by-step explanation:

The triangle shown is a isosceles triangle meaning two angles measure the same value and one angle measures different from the others

To find m∠A, subtract 180 since it’s the total ° among the angle minus 70° to be left with the two angles

180° - 70° = 110°

The two angles can’t each be measured 110° so we must divide 110° by 2 for the two angles to have the same degree

Thus, m∠A = m∠B and m∠A = 55°

AB = 6 and AC=13. Find BC.

Answers

Answer:

BC = 7

Step-by-step explanation:

AB + BC = AC

Substitute values for the line segments:

6 + BC = 13

Isolate line segment BC by subtracting both sides by 6:

6 - 6 + BC = 13 - 6

0 + BC = 13 - 6

BC = 7

Check your work:

6 + 7 = 13

13 = 13

Which expression is equivalent to 180?​

Answers

Answer:

[tex] \sqrt{2.2.3.3.5} [/tex]

[tex]\sqrt{2.2.3.3.5}[/tex] is equivalent to [tex]\sqrt{180}[/tex]. Correct option is 1. First, we look for perfect square factors within 180. We can factor 180 as follows: [tex]\(180 = 2^2 \times 3^2 \times 5\)[/tex]

Next, we can group the perfect square factors together:

[tex]\(180 = (2 \times 3)^2 \times 5\)[/tex]

Since we are taking the square root of 180, we can rewrite it as the square root of its perfect square factors multiplied by the remaining non-perfect square factor:[tex]\(\sqrt{180} = \sqrt{(2 \times 3)^2 \times 5}\)[/tex]

The square root of a perfect square is just the value of the number itself:

[tex]\(\sqrt{180} = 2 \times 3 \times \sqrt{5}\)[/tex]

Finally, we can simplify the expression by multiplying the numbers outside the square root [tex]\(\sqrt{180} = 6\sqrt{5}\)[/tex]

So, the expression [tex]\(6\sqrt{5}\)[/tex] is equivalent to [tex]\(\sqrt{180}\)[/tex], and it represents the positive square root of 180 with any perfect square factors taken outside the square root sign.

A number line shows 1 1/5, −2 2/5, and −1 3/5. Which statement is NOT true?

Answers

Answer:

The answer Is A 1 1/5 < -2 2/5

Step-by-step explanation:

It says that this statement is true because 1 1/5 is to the left of -2 2/5 on the number line but it is actually to the right because -2 2/5 is negative while 1 1/5 is positive therefore making it larger and the correct statement would be that    1 1/5 > -2 2/5

what is the distance between points (4,0) and (-2,-3)

Answers

Hi! I'm happy to help!

To solve this equation, we need to find how much distance is between the y coordinates, how much distance is between the x coordinates, and then use the Pythagorean Theorem.

Let's start with finding the distance between the x coordinates. The first x coordinate is 4, and the second is -2. This means that the distance in x is 6.

Next, we need to find how much distance is between the y coordinates. The first y point is at the y coordinate 0, and the second is at the y coordinate -3. This means that the distance in y is 3.

Now we use the Pythagorean Theorem, which says that a²+b²=c²

A and b refer legs of a right triangle, and c refers to the hypotenuse (longest side) of the right triangle. Imagine the two points on a line, the direct distance is the c, and the y and x movements alone are a and b.

Let's say x is a, and y is b. Let's insert our values:

6²+3²=c²

36+9=c²

45=c²

To find c, we need to find the square root of 45

√45

6.708203...

Rounds to about 6.7 in tenths.

So, the distance between those two points is about 6.7.

Which equation represents a population of 370 animals that increases at an annual rate of 11% ?

Answers

Answer:

D.

Step-by-step explanation:

the starting number is 370 and it gets multiplied by 1.11 every year so you would root the equation by t

The equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.

What is an exponential function?

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

We have:

A population of 370 animals that increases at an annual rate of 11%

Initial value a = 370

rate r = 11% = 0.11

The equation:

[tex]\rm p = a(1 + r)^t[/tex]

[tex]\rm p = 370(1 + 0.11)^t[/tex]

Thus, the equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.
