On Saturdays, Jorge coaches soccer for 1/12 of the day. He also coaches tennis and swimming, each for the same amount of time as soccer. What fraction of the day does Jorge spend coaching on Saturdays.

Answers

Answer:

3/12 or SIMPLIFIED = 1/4

Step-by-step explanation:

If he spends 1/12 of the day on soccer and he does tennis and swimming for the same amount of time that is just 1/12 +1/12+1/12=3/12 because each 1/12 is for each activity. So you answer (simplified) is 1/4

Answers

Answer:

J = - 20

Step-by-step explanation:

j + - 2 = - 22

j - 2 + 2 = - 22 + 2

j = - 20

b - 19 = - 11

b - 19 + 19 = - 11 + 19

b = 8

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a $7.50, 7, point, 50 delivery fee and $14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60

Whats the Inequality

Answers

Answer:

7.50 + 14x < 60

x < 3.75

Step-by-step explanation:

Let

x = number of pizzas ordered

Delivery fee = $7.50

Cost per pizza = $14

Total cost should be less than $60

The inequality

7.50 + 14x < 60

14x < 60 - 7.50

14x < 52.5

x < 52.5/14

x < 3.75

Tree B produces 10% more than tree A.
How many kilograms of plums in total does Yuri get from the trees?
Show your working​

Answers

Answer:

42kg

Step-by-step explanation:

We are given the amount of plums produced from Tree A. We simply need to find the amount produced by Tree B and add the two numbers up.

Step 1:

Tree B produces 10% more than Tree A, which produces 20kg of plums:

[tex]B=\frac{110}{100} *\frac{20}{1} \\\\B=\frac{110}{5}=\\\\B=22[/tex]

Ok! Tree B produces 22kg of plums. Let us find the total amount of plums Yuri gets from both trees.

Step 2:

[tex]Total=A+B\\\\Total=20+22\\\\Total=42[/tex]

Yuri gets 42 kg of plums from the trees.

You are baking a cake. The recipe asks for \frac{3}{5} 5 3 ​ cup of butter and you want to make \frac{1}{5} 5 1 ​ of the original recipe. How many cups of butter will you need?

Answers

Answer:

3/25 cup of butter

Step-by-step explanation:

You are baking a cake. The recipe asks for 3/5 cup of butter and you want to make 1/5 of the original recipe.

The calculation for the above question is given below:

1 recipe = 3/5 cup of butter

1/5 recipe = x

Cross Multiply

x × 1 recipe = 1/5 recipe × 3/5 cup of butter

x = 1/5 recipe × 3/5 cup of butter /1 recipe

x = 3/25 cup of butter

Therefore, you will need 3/25 cup of butter

One tool used to study refraction is a glass or acrylic prism. Two of the prisms more commonly used to study light refraction are a triangular prism with an equilateral triangle for its base and a triangular prism with a right triangle for its base. In this task, you will check whether the measurements found prove the two given prisms are right prisms and whether their bases are equilateral or right triangles.

The prism said to have an equilateral triangle base has the measurements shown.



Part A
Are the bases of the prism equilateral triangles? Why or why not? Note: The bases of a triangular prism are triangles.



Part B
For this prism to be a right prism, all the lateral faces must be rectangles. Is enough information given to prove the lateral faces are rectangles? Why or why not?



Part C
Without using a protractor, you can determine whether the angles are right angles by measuring the length of the diagonal and applying the converse of the Pythagorean Theorem.



The length of both diagonals for each lateral side is 13 centimeters. From this, can you prove that the lateral sides are rectangles? Why or why not?



Part D
Some of the measurements of the triangular prism with a right triangle base are shown.



What is the length of the hypotenuse of the base?



Part E
Which lateral face has the largest area, the bottom one, left one, or diagonal one? What is its area?

Answers

Answer:

A: The bases of a triangular prism are equilateral triangles, since they have equal sides: 5, 5, and 5 yes, since if all lateral faces are rectangles, rectangles are formed from 4 perpendicular segments, thus, if all edges of the lateral faces are perpendicular, then they are rectangles

B:they have equal length sides and equal angles. For this to be true, the bases must be squares. Because it is a right prism, the lateral faces are rectangles.
C:If we have following equation right, then the angle between shorter sides is right angle:

13² = 12² + 5²

169 = 144 + 25

169 = 169

D:4*sqrt(2)

E: LSA of a cube = 100 in²

Consider the functiony = 3x^5 - 25x^3 + 60x+ 1. Use the first derivative test to decide whether this function has a maximum at x = 1. Which of the following describes what you found?

A. The derivative is positive to the left of x = 1 and positive to the right of x = 1, so the function has neither a relative maximum nor a minimum at x = 1.

B. None of these apply

C. The derivative is negative to the left of x = 1 and positive to the right of x = 1, so the function has a relative minimum at x = 1.

D. The derivative is positive to the left of x = 1 and negative to the right of x = 1, so the function has a relative maximum at x = 1.

E. The derivative is positive to the left of x = 1 and negative to the right of x = 1, so the function has a relative minimum at x = 1.

Answers

Answer:

Option A

Step-by-step explanation:

Expression for the given function is,

y = 3x⁵ - 25x³ + 60x + 1

First derivative of the given function will be,

y' = 15x⁴ - 75x² + 60

For the critical points of the function,

y' = 0

15x⁴ - 75x²+ 60 = 0

x = 1

On the left side of x = 1,

Let x = 0

y' = 15(0)⁴ - 75(0)²+ 60

y = 60 [Positive]

On the right side of x = 1,

Let x = 3

y' = 15x⁴ - 75x²+ 60

y' = 15(3)⁴ - 75(3)² + 60

y' = 1215 - 675 + 60

y' = 600 [Positive]

Since, the derivative is positive on both the sides of x = 1,

Function will have neither maximum neither minimum at x = 1.

A bag contains two striped cubes, five dotted cubes, five white cubes, and three red cubes. What is the probability of drawing two striped cubes in succession, without replacing the first cube drawn

Answers

The probability of drawing two striped cubes in succession, without replacing the first cube drawn is

1/136​

What is probability?

Generally, The possibility of an occurrence may be quantified using the concept of probability. It is a number between 0 and 1, where 0 indicates that an event will never happen and 1 indicates that an event will definitely take place.

Probabilities may be represented as fractions, decimals, or percentages somewhere between 0 and 1, inclusive. In each given circumstance, the sum of the probabilities of all of the conceivable outcomes must equal 1.

The probability of drawing a striped cube on the first draw is 2/17 (there are 2 striped cubes out of a total of 17 cubes in the bag).  

The probability of drawing a second striped cube, given that the first one was not replaced, is 1/16 (there is now only 1 striped cube left in the bag out of a total of 16 remaining cubes).

The probability of both events happening is the product of the individual probabilities:

(2/17) * (1/16) =  1/136​

A flower shop has 8 bouquets of red lilies, 5 bouquets of pink lies and 7 bouquets of violet lilies. Raymond who is colorblind buys his gf a bouquet of lilies. What is the probability of raymond not picking red lilies

Answers

Answer:

12/20, or 3/5

Step-by-step explanation:

To find the probability of Raymond not picking red lillies, we first must establish the total amount Raymond can choose from as well as the amount of non-red lillies.

The total amount Raymond can choose from is the amount of bouqets. There are 8 red ones, 5 pink ones, and 7 violet ones. This means that there are 8+5+7=20 total bouquets.

The amount of non-red lillies is determined because we are asked to find the probability of selecting a non-red bouquet. We find the number of non-red bouquets by subtracting the total (20) by the number of red bouquets (8) to get 12.

Therefore, the total amount is 20 and the number of non-red bouquets is 12. Thus, if Raymond picks one bouquet, the probability of him selecting a non-red one is 12/20, or 3/5. The probability of him picking up a red bouquet, similarly, would be 8/20, as there are 8 options of red bouquets out of 20 total
