Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200​

Answers

It would take Brad five months with adding $25 every month with a starting value of $75 in his bank account to save at least $200

The inequality representing the problem will be x+3 ≥ 8

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.

Let the number of months be x,

75 + 25x ≥ 200

25(3+x) ≥ 200

x+3 ≥ 8

Hence, The inequality is x+3 ≥ 8

Which type of triangle has side measures of 5 cm, 9 cm, and 12.7 cm and one angle measure of 128°?

A.
acute isosceles

B.
obtuse scalene

C.
obtuse isosceles

D.
acute scalene

Answers

I haven’t seen a question like this in years, but I think the answer may be obtuse scalene due to the fact that the side measures are all different, (not equal) and the angle measure is 128 degrees, which is greater than 90.

This question is dealing with classification of triangles based on angles or on number of equal sides.

the triangle is called an Obtuse Scalene Triangle

Now, the classification in terms of angles are;

- Acute angle is when the angle measures between 0 and 90 degrees.

- Obtuse angle is when the angle is greater than 90 but less than 180 degrees.

- right angle is when the angle is exactly 90 degrees.

- Reflex angle is when the angle is greater than 180 but less than 360 degrees.

Now the classification in terms of equal sides;

- Isosceles triangle is one that has  2 equal sides.

- Equilateral triangle is one that has 3 equal sides.

- Scalene triangle is one that has no equal sides.

The lengths of the three sides of the triangle given are;

5 cm, 9 cm, and 12.7 cm

The three sides are not equal and from definition above it is called scalene triangle.

The angle given is 128° and from definition earlier, it is an obtuse angle.

In conclusion, the triangle is called an Obtuse Scalene Triangle

the Pythagorean theorem is

c is the hypotenuse which is the side opposite of the right angle

plug the numbers into the Pythagorean theorem

when squaring a square root, just take the number in the radical and get rid of the radical

  Part A: B

  Part B: 1

Step-by-step explanation:

Part A:

The meaning of "at most" is "less than or equal to." If we assume that the variables x and y represent numbers of loaves of banana bread and nut bread, respectively, then the first problem statement tells you ...

  x + y ≤ 30 . . . . . the total of loaves baked is at most 30

Only one answer choice has this inequality listed: choice B.

__

Part B:

The numbers of loaves of bread will not be negative. The only quadrant that has both coordinates positive is the 1st quadrant.

Comment on quadrant

Real-world problems involving numbers of items are often expressed in terms similar to those seen here. The assumption that is made in all such problems is that the quantity of items cannot be negative. That is, the constraints x ≥ 0 and y ≥ 0 are always considered part of the problem description. These limit solutions to Quadrant 1. (or I, if you use Roman numerals for numbering quadrants)

Lynn is making a snack. The recipes call for 38 cup of water for oats and 14 cup of water for dried fruit. She only has 1 cup of water. Does she have enough to make her snack? Explain. No. Both recipes call for more than 1 cup, so the recipes will use more than 2 cups altogether. No. Both recipes call for more than half a cup, so the recipes will use more than 1 cup altogether. Yes. Both recipes call for exactly 1 cup, so the recipes will use exactly 1 cup altogether. Yes. Both recipes call for less than half a cup, so the recipes will use less than 1 cup together

Answers

Answer:

3.4/6

Step-by-step explanation:

No, Lynn do not have enough water to make her snack.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, the recipes call for 3/8 cup of water for oats and 1/4 cup of water for dried fruit.

You need to add up the quantities of water needed first. That will then tell if she has enough water.

Convert the fractions to decimals then add them up:

3/8 = 0.375

1/4 = 0.25

= 0.25 + 0.375

= 0.625 cups of water is required.

This is less than the 1 cup she has so she has enough water to make the snack.

No, Lynn do not have enough water to make her snack.

Answers

Answer:

6 ways

Step-by-step explanation:

William has a sticker album.

We are told in the question that:

Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers

The many different ways that can he put the stickers in the album is calculated as:

18 stickers ÷ ( 1 stickers + 2 stickers)

= 18 ÷ 3

= 6 ways

Therefore, the different ways that he can put the stickers in the album is 6 ways

Answer: 150 degrees

Step-by-step explanation:

The number of degrees did it rotate altogether should be considered as the 150 degrees.

Calculation of the number of degrees:

Since A sprinkler rotates 75°, pauses, and then rotates another 75

So, here total degrees be like

= 75 degrees + 75 degrees
