Answer 1

Answer:

x column- 1.25, 7.5, 45.

y column- 5, 30, 180.

Step-by-step explanation:

Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.

A rectangle has a length of 8.3 cm and a perimeter of 22.4 cm.
What is the width of the rectangle in decimal form?​

Answers

Answer:

the perimeter is simply 2L + 2W

So lengthy 8.3

2(8.3) + 2(w) =22.4

16.6=2(w) =22.4

2(w) = 5.8

w = 5.8 divide by 2

The width is 2.9

3/4 of 24 is 3 groups of 6, which is 18. So Han ate 18 less than Tyler, or Han at 6. So you take the 24(x) and you subtract 24 of 24(-3/4x) to get to Han total.

Answers

Answer:

Step-by-step explanation:

Let the total amount ate by Tyler and Han be 24

Let the amount Tyler ate be x

Amount Han ate be y

If Tyler ate 3/4 of the total, then Amount ate by Tyler is expressed as;

x = 3/4of 24

x = 3/4×24

x = 3×6

x = 3(6)

x = 18

Hence the amount Tyler ate is 18

If Han ate 18 less than Tyler, the amount ate by Han will be;

Han y = 24-(3/4(24)

y = 24-{3(6)}

y = 24-18

y = 6

Hence the total Han ate is 6

Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side? 16 inches 17 inches 24 inches 25 inches

Answers

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

[tex]$c^2 > a^2 +b^2$[/tex]

[tex]$c^2 > (9)^2 +(14)^2$[/tex]

[tex]$c^2 > 81 +196$[/tex]

[tex]$c^2 > 277$[/tex]

c > 16.64

Therefore the smallest possible whole number is 17 inches.

It should be noted that the length of the unknown side will be 17 inches.

From the information given, we are informed that the sides of an obtuse triangle measure 9 inches and 14 inches.

Therefore, the third side will be:

c² = 9² + 14²

c² = 81 + 196

c² = 277

c = ✓277

c = 16.64

c = 17

In conclusion, the correct option is 17 inches.

Answers

Answer:

Speed is 171.6 ft/s and distance is 1716 feet

Step-by-step explanation:

Given that,

The speed of a parachute = 117 miles per hour.

1 mph = 1.47 ft/s

117 mph = 171.6 ft/s

We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,

d = vt

[tex]d=171.6\ ft/s\times 10\ s\\\\=1716\ \text{feet}[/tex]

Hence, this is the required solution.

8. The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70? Record your answer and fill in the bubbles on your answer document.​

Answers

Answer:

y = 17.5

It says y is proportional to x, and y = 35 when x = 140, but we don't know what y is when x = 70. So since y is proportional to x and x = 140 we have to find out how 140 gets to 70, and that is dividing by 2 because 70 is half of 140. So then you would just divide the previous y value, 35, by 2, and you would get 17.5. And there you go, you've got you're answer.

Karra is at the dollar store buying bags of chips for her sleepover party. For every 5 bags of chips she buys, she pays $6. What is the price per bag of chips? *Money always has two numbers after the decimal.

Answers

Answer:

$1.20

Step-by-step explanation:

Given that:

Price paid to buy 5 bags of chips = $6

To find:

Price per bag of chips in two digits after the decimal.

Solution:

To find the price of each bag of chips, we need to divide the price of 5 bags of chips with 5.

i.e. we need to divide $6 with 5, then we will get the price of each bag of chips.

[tex]\text{Price of each bag of chips}=\dfrac{\text{Price of 5 bags of chips}}{5}\\\Rightarrow \dfrac{\$6}{5} = \bold{\$1.2}[/tex]

Therefore, the answer is:

Price of each bag of chips is $1.2.
