Two sides of a triangle measure 8 ft and 12 ft, respectively. The included angle is 65˚. Approximately how long is the third side of the triangle?

Answers

Answer 1

Answer:

Approximately 11 feet.

Step-by-step explanation:

Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos C

⇒ [tex]x^{2}[/tex] = [tex]8^{2}[/tex] + [tex]12^{2}[/tex] - 2(8 x 12) Cos[tex]65^{o}[/tex]

       = 64 + 144 - 192 x 0.42262

       = 208 - 81.143

       = 126.857

x = [tex]\sqrt{126.857}[/tex]

  = 11.2631

x ≅ 11

The length of the third side of the triangle is approximately 11 feet.

A half game in football is 45 min. At one point, a half was extended so that it was 48 minutes 30 seconds long. By what percentage was the half extended? Round to the full percentage.

Answers

Answer:

8%

Step-by-step explanation:

Multiply the number 45 by at least 1 point 0 something and therefore.  We can assume that a 5% increase is around 47 minutes and 15 seconds and a 10% increase is around 49 minutes and 30 seconds ranging for you to use from 6% to 9%.  The exact answer for the increase is around 7.78%, for me, I would plug in the equation like 45*1.7 and 45*1.8 on the calculator for more accuracy since you would need to round to the full percentage if it's between 7.5% to the exact number, it would be fully rounded to 8% since you would need at least a 5 to round up.

Mackenzie has a loyalty card good for a 20% discount at her local hardware store. What would her total in dollars and cents be, after the discount and before tax, if the total cost of all the items she wants to buy is $17.45? Round to the nearest cent.

Answers

Answer: $14.0

Step-by-step explanation:

For us to calculate this question, we have to find 20% of $17.45 and then subtract the value gotten from $17.45. This will be:

= $17.45 - (20% × $17.45)

= $17.45 - (0.2 × $17.45)

= $17.45 - $3.49

= $13.96

= $14.0 to nearest cent

joe spent $15. he bought 2 cans of oil. abouthow many gallons of gasoline did he buy

Answers

The expression that can be used to determine the total amount of Joe spent on gasoline and oil is 2.85g + 3.15c.

The number of gallons of gasoline he bought is 3.0 gallons.

How to find the expression to determine the total amount of gas bought?

Joe bought g gallons of gasoline for 2.85 dollars per gallons and c cans of oil 3.15 dollars per can.

Therefore, the expression that can be used to determine the total amount of Joe spent on gasoline and oil is as follows:

total amount = 2.85g + 3.15c

where

g = number of gallons of gasolinec = cans of oil

Joe spent 15 dollars . He bought 2 cans of oil . The amount of gallons of gasoline he bought can be calculated as follows:

15 = 2.85g + 2(3.15)

15 = 2.85g + 6.3

15 - 6.3 = 2.85g

8.7 = 2.85g

g = 8.7 / 2.85

g = 3.05263157895

Therefore,

g = 3.0 gallons of gasoline

Micah and Joel each have a set of five rational numbers. Although their sets are not the same, their sets of numbers have absolute values that are the same. Show an example of what Micah and Joel could have for numbers. Give the sets in order and the absolute values in order.

Answers

Solution :

Ordering numbers means we have to arrange the numbers in ascending order or in a descending order i.e. from small value to big or from big value to small value.

The order of the positive numbers is same as the order of the absolute values and their order of the negative numbers are opposite to the order of their absolute values.

In the context, if Micah is having numbers 1, 2, 3, 4, 5, then the order of the absolute values of the numbers would be 1, 2, 3, 4, 5. Similarly, if Joe is having numbers -5, -4, -3, -2, -1, then the order of their absolute value will be also 1, 2, 3, 4, 5.

And if Micah have the numbers -5, -3, -1, 2, 4, then the absolute values of his numbers is 1, 2, 3, 4, 5. Also if Joe have numbers as -4, -2, 1, 3, 5, then his order of absolute values is also 1, 2, 3, 4, 5.

∠8=∠88(corresponding angles are equal)

∠3=∠88(alternate interior angles are equal

Angles ∠1, ∠3 and ∠8 are equal to 88°.

What is angle?

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Angle 1 and 88 are the vertically opposite angle, so they are equal

∠1 = 88°

Angle 1 and angle 3 are corresponding angle, so they are equal

∠1 = ∠3 = 88°

Angle 3 and 8 angle are vertically opposite angle, so they are equal

∠3 =∠8  = 88°

Find the length of the rectangle if the perimeter is 244 yards the length is 18 less than three times the width?

Answers

Answer:

The Length of rectangle is 87 yards.

Step-by-step explanation:

Let width = w

Length = 3w-18

Perimeter of rectangle = 244 yards

We need to find length of rectangle.

First we need to find value of w

The formula used will be: [tex]Perimeter=2(length+width)[/tex]

Putting values and finding w

[tex]Perimeter=2(length+width)\\244=2(3w-18+w)\\244=2(4w-18)\\244=8w-36\\244+36=8w\\8w=280\\w=\frac{280}{8}\\w=35[/tex]

So, w= 35

The width of rectangle w = 35 yards

The length of rectangle l = 3w-18 = 3(35)-18 = 105-18 = 87 yards.

So, the Length of rectangle is 87 yards.

A ratio is a comparison of two quantities. For example, the ratio of cows to pigs on a farm could be 1 to 3. For every 1 cow, there are 3 pigs. The ratio of chocolate chips to raisins in a cookie could be 5 to 9. For every 5 chocolate chips in the cookie, there are 9 raisins. Do you notice a repeating phrase in these examples? “For every” is key ratio language. It tells you how much of one quantity exists in comparison to the other quantity. A ratio consists of just the numbers, not the units. If someone asked the ratio of chocolate chips to raisins in the cookie example, you’d say 5 to 9.
