3: 300

4: 3/10

5: 42

Step-by-step explanation:

1: 2/5 × 40

80÷ 5

16

girls = 40- 16

= 24

2: 1/3 × 960

960 ÷3

= 320

Left = 960 - 320

= 640

3: 3/8 × 480

1440 ÷ 8

= 180.

Left = 480 - 180

= 300

4: 2/5 × 3/4

= 6/20

= 3/10

5: 2/5 × x = 18

2x = 28 × 5

X-(-y-z+3) remove the parentheses

Answers

Answer:

x + y + z - 3

Step-by-step explanation:

Basically, putting a negative sign before parentheses signifies that you want to flip the sign of everything within the parentheses. This can also be explained by the negative sign representing -1.

Knowing this, we can just multiply everything within by -1.

-y -> y

-z -> z

3 -> -3

We now have y + z - 3, just put this into the original expression and we have our final answer of:

x + y + z - 3

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?

Answers

Answer:

118°

Step-by-step explanation:

When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.

Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.

Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.

(5x + 17) + (15x - 17) = 180

5x + 15x + 17 - 17 = 180

20x = 180

20x/20 = 180/20

x = 9°

Nkw let's substitute x = 9 into the equations

5x + 17 =

5(9) + 17 =

= 62°

15x - 17 =

15(9) - 17 =

= 118°

Both equations should add up to be 180°.

Therefore the measure of the largest angle is 118°.

dollars?
$2,567
$102.68
$132.12
$3,414

Answers

Answer:

$132.12

Step-by-step explanation:

19.43 pesos = $1

2567 pesos = ?

1. First divide 2567 by 19.43 to find the exact number of dollars:

2567 ÷ 19.43 = 132.1152856

2. Round this value to 2 decimal places:

132.1152856 ≈ $132.12

Step-by-step explanation:

19.43 pesos = 1 U.S. dollar

So 1 peso = [tex]\frac{1}{19.43}[/tex] U.S. dollar

2567 pesos = [tex](\frac{1}{19.43} )(2567)[/tex] U.S. dollar

= 132.115286 U.S. dollar

You buy tomatoes sauce for 0.37per ounce. One portion of potatoes gnocchi requires 3.5 ounces of tomatoe sauce. How much does the sauce for one portion cost

Answers

Answer:

it would cost $0.74 = 74 cents

Step-by-step explanation:

The cost of one ounce of tomato = $0.37

1 portion of potato gnocchi requires 2 ounces of tomato sauce.

To find the cost of one portion of the potato gnocchi, we have to simply find the cost of 2 ounces of tomato sauce.

That is:

Cost = 2 * 0.37 = $0.74

Hence, one portion of potato gnocchi costs $0.74

Since $1 = 100 cents, the cost in cents will be:

0.74 * 100 = 74 cents

Do you think this poster was effective? Explain why or why not. Select all the correct answers.Exotic animals are meant to live in their natural habitats. If they are not in their natural homes, then they should be in controlled settings such as zoos. The average person is not equipped to care for them in a typical home. Experts estimate that approximately 20,000 exotic wild cats are living as pets in the United States. Sadly, that is almost more than the number of tigers that exist in their natural environment. In states such as Texas, people must have a license to own wild animals such as tigers, however, the state does not have regulations to guarantee the protection of those animals once they have been bought.Caring for exotic pets is extremely costly and can become dangerous. Annual food costs for one tiger cub can cost up to $6,000. These cubs can even weigh up to 500 pounds in a just a few short months and become strong enough to overpower the average adult. These animals require plenty of space to roam and feel comfortable. Luckily, when pet owners are worried about not doing a good job raising these animals, there are pet sanctuaries that are willing to take the animals and care for them.Monty is writing an argumentative text about not having exotic animals as pets. A classmate read an excerpt and suggested that Monty needs to strengthen his credibility.What are two changes Monty can make to strengthen the credibility of his paper?A.
