Answer:

180

Step-by-step explanation:

Answer:

117 ft³

Step-by-step explanation:

The tent is composed of a cuboid and a triangular prism

V ( cuboid) = 6 × 8 × 2 = 96 ft³

V(prism) = Ah ( A is the area of triangle and h is length )

              = [tex]\frac{1}{2}[/tex] × 6 × (5.5 - 2) × 2

              = 3 × 3.5 × 2

              = 21 ft³

Total volume = 96 + 21 = 117 ft³

Jason has saved 41% of what he needs to buy a 73$ skateboard . Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly

Answers

Answer:

No, Jason did not solve correctly

Step-by-step explanation:

Jason has saved 41% of what he needs to buy a 73$ skateboard.

Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly

Let compare both statements

50% of 70 = 70 ÷ 0.5 (140)

50% × 70 = 140

50/100 × 70 = 140

35 ≠ 140

1 hamburger 0.13

Check

0.13 x 15 = 1.95

Answer:

[tex] \bf \huge \: 15[/tex]

Step-by-step explanation:

Given that :

Shiva has 1.95 pounds of meat.She uses 0.13 pound of meat to make one hamburger.

to find :

How many hamburgers can Shiva make with the meat she has ?

explanation :

⟼ total meat = 1•95 pounds

⟼ use meat to make a hamburger = 0•13 pounds

⟼ how many hamburgers shiva make with the total meat = total meat / use meat to make a hamburger

⟼ how many hamburgers shiva make with the total meat = 1•95 / 0•13

⟼ how many hamburgers shiva make with the total meat = 15 hamburgers .

shiva make 15 hamburgers with 1•95 pounds meat.

verification :

let take shiva make 15 hamburgers with 1•95 pounds meat.

⟼ 0•13 × 15 = 1•95

1•95 = 1•95

hence verified ☑️

Answer: See below

Step-by-step explanation:

1) 1/2 x 3.14 x 35^2

1/2 x 3.14 x 1225

1/2 x 3846.5

A = 1923.25 yd^2

2) (3.14)r^2

(3.14) (35)^2

3846.50 yd^2

3) P = d + (3.14)r^2

P = 70 + (3.14) (35)

P = 70 + 109.90

P = 179.90 yd

4) P = 2( l + w)

P = 2 (70 + 100)

P = 2 (170)

P = 340

Perimeter of the square minus the perimeter of the circle.

340 - 179.90 = 160.10 yd


3. When should points of intersection be included within the feasible region of a system of nonlinear inequalities
and why

Answers

Answer:

Points of intersection should be included within the feasible region (the solution set) of a system of nonlinear inequalities when the boundary lines that create the point are solid. A dashed line indicates that the points are not included in the solution set. Therefore, if one boundary line is dashed and one is solid, the point of intersection will not be included within the feasible region.

Step-by-step explanation:

Points of intersection should be included within the feasible region of nonlinear inequalities when the boundary lines that create the point are solid.

What is Inequality?

This is defined as an expression in which the sides are not equal to each other.

The presence of boundary lines which have dashed and solid ones, the point of intersection will not be included within the feasible region.

Ella has three pitchers that each hold 1.5 liters of lemonade. She charges $0.38 for every 100 milliliters of lemonade.

How much will Ella make if she sells all of the lemonade in the pitchers?

Answers

Let her earning be x
The volume of 1 pitcher in millilitres = 1.5 x 1000 = 1500 ml [1 liter is 1000 milliliter]
3 pitchers = 1500 x 3 = 4500 ml
100 ml = 0.38 rs.
4500 ml = 0.38 x 4500= 1690 rs.
Answer:
$17.10
Step-by-step explanation:
theres 1000 millileters in a liter so .38 x 10 = 3.8
500 more millileters so .38 x 5 = 1.9
3.8+1.9=5.7
5.7 for one pitcher so multiply 5.7 by 3 = 17.1

The number of points Jaden scored in a game is less than 45, and is also a multiple of 7. How many points could Jaden have scored

Answers

Answer:

35

Step-by-step explanation:

The first few multiples of 7 are:

× 7 = 7

× 7 = 14

× 7 = 21

× 7 = 28

× 7 = 35

× 7 = 42

× 7 = 49

× 7 = 56

× 7 = 63

× 7 = 70

The number of points Jaden scored in a game less than 45, and a multiple of 7 is 35 points

How to find how many points Jaden scored?

The multiples of 7 are;

7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105......

Recall,

The number of points Jaden scored in a game is less than 45

From the options, we are left with 17 and 35

17 is not a multiple of 7

Therefore, the number of points Jaden scored in a game less than 45, and a multiple of 7 is 35 points

A bag of sweets contains only mints, sherberts and toffees.
The ratio of the number of mints to sherberts is 2:3.
The ratio of the number of sherberts to toffees is 7:5.
What fraction of the sweets are sherberts?

Answers

The Lowest Common Multiple Of 3 and 7 is 21
This means the ratio of mints:sherberts:toffees can be written as 14:21:15
The fraction of sweets that are sherberts is therefore 21/(14+21+15) = 21/50

The fraction of the Sweets are Sherberts is 21/50

What is mathematical expression?

When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.

Mints:Sherbets = M:S = 2:3

Sherberts:Toffees = S:T = 7:5

Mints:Sherberts:Toffees = M:S:T = 2*7 : 7*3 : 3*5 = 14:21:15

Total sweets = 14+21+15 = 50 (Adding all the fractions  after multiplying)

Therefore, the fraction of the Sweets are Sherberts = 21/50

Two fair, six-sided dice are rolled. What is the probability that the resulting total is even or greater than 10?

Answers

Answer:

Step-by-step explanation:

Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.

The probability that the resulting total is even or greater than 10 is 7/12.

Given that, two fair, six-sided dice are rolled.

What is the probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Here, sample space of two dice is

S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6), (2,1),(2,2),(2,3),(2,4),(2,5),(2,6), (3,1),(3,2),(3,3),(3,4),(3,5),(3,6), (4,1),(4,2),(4,3),(4,4),(4,5),(4,6), (5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}

Number of favorable outcomes = 18

Total number of outcomes = 36

Probability of getting the total is even = 18/36

= 1/2

Number of favorable outcomes = 3

Probability of getting the total is greater than 10 = 3/36

= 1/12

So, probability is 1/2 + 1/12

= 6/12 + 1/12

= 7/12

Therefore, the probability that the resulting total is even or greater than 10 is 7/12.
