6.A circle has a diameter of 11 inches. What is the circumference of the circle using ≈ 3.14? = . Single choice.

Answers

Answer:

Circumference of the circle = 34.54 inches

Step-by-step explanation:

Explanation

Given that diameter of the circle

                                    d = 11inches

The radius of the circle    

                                [tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]

Circumference of the circle

                              = 2πr

                             = 2×3.14×5.5

                           = 34.54

Final answer:-

Circumference of the circle = 34.54 inches

Tyler's grandma purchased a savings bond for him when he was born. The bond was bought for $500.00. The value of the savings bond increases by 5% a year. Tyler's grandma wants Tyler to use it for college, so he is not allowed to touch it until he is 18.

How much money will Tyler have when he is 18

Answers

Answer: 950 dollars

Step-by-step explanation:

5% of 500 dollars is 25 dollars, so since 5% is 25 dollars,  multiply that by how many years he can have it (18). So 18 * 25 = 450. 450 added to the starting 500 dollars is 950 dollars. Your welcome, I'm new so glad I could help.

Indicate whether the measures 3.1, 4.8, and 10.2 can be the side lengths of a triangle. If they can, classify the triangle.

Answers

The measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

What is triangle inequality?

"It states that the sum of any two sides must be greater than the third side."

For given question,

we have been given the measures 3.1, 4.8, and 10.2  

We need to check whether given measures can be the side lengths of a triangle.

First we check whether the given measures obey triangle inequality or not.

3.1 + 4.8 = 7.9

7.9 < 10.2

This means, the measures 3.1, 4.8, and 10.2 do not obey triangle inequality

Therefore,  the measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

help with this bounds question please

Answers

Answer: 6.68km/litre

Step-by-step explanation:

Distance(d) = 187km ( to 3 significant figures)

Petrol(p) = 28litres ( to 2 significant figures)

A number, x, rounded to 1 significant figure is 200

Write down the error interval for x

Calculating the lower and upper bound for both 'd' and 'p'

Upper bound 'd' = 187.5km

Lower bound 'd' = 186.5km

Upper bound 'p' = 28.5km

Lower bound 'p' = 27.5km

Therefore,

Petrol consumption (C) = d/p

Upper C = 187.5 / 28.5 = 6.57894

Lower C = 186.5 / 27.5 = 6.781818

Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379

= 6.68km/ litre ( to 3 significant figures)

To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.

Using 3 significant figures ensure that we capture the C better, instead of early rounding.

Answers

Answer:

m∠C = 44°

Step-by-step explanation:

In ΔCDE,

m∠C=(4x−16) ∘

m∠D=(6x−1) ∘

m∠E=(4x−13) ∘ .

The sum of angles in a triangle = 180°

Step 1

We solve for x

m∠C + m∠D + m∠E

(4x−16)° + (6x−1)° + (4x−13)° = 180°

4x - 16 + 6x - 1 + 4x - 13 = 180°

4x + 6x + 4x -16 - 1 - 13 = 180°

14x - 30 = 180°

14x = 180+ 30

14x = 210

x = 210/14

x = 15

Step 2

Find m∠C

m∠C = (4x−16)°

m∠C = (4 × 15 - 16)°

m∠C = (60 - 16)°

m∠C = 44°

Which statement about this product is true? 0.44×(−5 3/4)
It is equal to 0 because 0.44 rounded to the nearest whole number is 0, and 0 times any number is 0.


It is equal to −534 because 44 is equal to 1, and 1 times any number equals that number.


It is greater than −3 because 0.44×534 is less than 12×6.


It is less than −534 because multiplying by a number less than 1 gives a smaller number.

PLZ HELP IM BEGGING

Answers

Answer:

-x+y= -14 (get this equation to where you can easily plug it in for a variable)

y= x -14

5x +6y =26 (plug the value above in for y and then solve)

5x + 6 (x-14) = 26 (use the distributive property)

5x +6x - 84 = 26 (combine like terms on the left side)

11x - 84 =26 (add 84 to both sides)

11x = 110 (divide both sides by 11 to isolate the x-variable)

x= 10 (this is the value for x. plug it into the easier equation and solve)

-(10) +y = -14

y= -4

(10, -4) (this is the solution for the system of equations)

(-5,_)

Answers

Answer:

(-5, -8); the missing value is -8

Step-by-step explanation:

First, you need to simplify the given equation to isolate y

1: -3x + 7y = 5x + 2y (Given)

2: 7y = 8x + 2y (Add 3x to both sides)

3: 5y = 8x (Subtract 2y from both sides)

4: y = 8/5x (Divide both sides by 5)

Now, you can use this to solve for the missing y in value set (-5, y)

where y = 8/5x and x = -5,

y = 8/5(-5)

y = -8

so, the missing value is -8
