Find the area of the composite shape

Answers

Answer 1

Step-by-step explanation:

Radius = 4 ft

Side of the square = 8 ft

Area of circle = πr² ≈ 3 × 4² = 48 ft²

Square area = a² = 8² = 64 ft²

area of composite shape = Square area - Area if circle = 64 - 48 = 16 ft²

Sara takes 1/6 of an hour to vacuum his moms car it takes 4 times that long to wash the car then it takes you to wax the car twice the amount of time to wash it how long does it take Sarah in total to vacuum wash and wax her moms car

Answers

Answer:2 hours & 10 minutes Step-by-step explanation:1/6 of an hour is 10 minutes. She vacuumed for 10 minutes. It took 4 times as long to wash the car so 10 * 4 = 40. She washed the car for 40 minutes. It took her twice as long to wax the car as it did for her to wash it so 40 * 2 = 80. She waxed the car for 80 minutes. 10 + 40 + 80 = 130 minutes or 2 hours and 10 minutes.

A flagpole casts a shadow that is 23 feet long. Jorge is 5.25 feet tall, and
while standing near the flagpole he casts a shadow that is 3 feet long. How
tall is the flagpole?

Answers

Answer:

5.5

7.5 =

23.5

7.5h = 129.25

h = 17.2

The flagpole is 17.2 feet long.

The measure of height of flagpole is 40.25 feet.

Given that, a flagpole casts a shadow that is 23 feet long.

What are heights and distances?

Heights and Distances is a study about the applications of Trigonometry. It has many real-life applications, such as measuring the object’s height, depth of the object, the distance between two celestial objects etc. The formulas and the ratios of trigonometry are helpful in the study of heights and distances.

Jorge is 5.25 feet tall, and while standing near the flagpole he casts a shadow that is 3 feet long.

Let the height of the flagpole be x.

Now, tan θ=5.25/3 -------(I)

and tan θ=x/23 -------(II)

Equation (I)=(II), we get

5.25/3 = x/23

⇒ 3x=5.25×23

⇒ 3x=120.75

⇒ x=120.75/3

⇒ x=40.25 feet

Therefore, the measure of height of flagpole is 40.25 feet.

x =5 and z = 4 z2 - 2x

Answers

Answer:

Whenever you see a letter beside a number, just know you should multiply that number by the letter. So z = 4, then 2z = 2×4, and x = 5, then 2× 5.

so : 2×4 = 8 - 2×5

so : 8-10

so the answer would then be -2.

Jose wants to plan a skate party for his younger cousin's birthday. Skate Land charges a $65 flat fee and $7.50 per person.
Skate Land uses the equation C = 7.50p + 65 (C = total cost; p = number of people ) to calculate the total cost
based on the number of people attending. Find the total cost, C, of the birthday party if Jose invites 30 friends and family
members.

Answers

Answer:

$290

Step-by-step explanation:

We can use the equation that Skate Land created to find the total cost

C = 7.50p + 65

p = people so if we have 30 people, we have to solve 7.50 x 30

C = 225 + 65

we can now add the flat fee of $65 to get the total cost for the birthday part

C = $290

Using the same triangle as above, calculate the area of the triangle. You must show TWO methods for calculating the area of the triangle. Round both answers to nearest tenth. Hint: you should be using the same values you provided in question 3 and you can use any values you calculated in question 3 as well.

Answers

Answer:

Step-by-step explanation:

Area of a triangle is 1/2 * b * h

b = base, the one labeled b on the diagram

h = height, the dotted line in the middle

so, you do pythagorean theorem with a and b to find the dotted line

a² + b² = h² (h is for height)

h = [tex]\sqrt{a^{2} +b^{2}}[/tex]

Then, you just plug in the numbers from question 3 to find h and then you do

1/2 * b * h

pear is the heaviest, and the strawberry is the lightest

Step-by-step explanation:

This is really simple! Looking at the weight scale, the heavier object always goes lower than the lighter object. Knowing this, we can figure out which is heavier and which is lighter.

10.

Bag A is LIGHTER than Bag B

Bag B is LIGHTER than Bag C

Looking at these we can infer that bag c is heavier than both.

So, Bag A is LIGHTER than Bag C

11. The pear falls lower than the apple, meaning it is heavier. The apple falls lower, meaning is it heavier than the apple. We can infer that the pear is the heaviest, and the strawberry is the lightest

Someone plz help, I will give them brainiest ObjectiveMake a function that solves the quadratic equation, outputting both values of X. You do not have to worry about imaginary numbers. That is, I will only use input that creates a real output (such as the example screenshots).NOTE: A function that uses the C version of pass by reference is required to get full credit on this assignment. The C++ form of pass by reference will receive no credit.DetailsSTEP 1#include at the top of your file so that you can use the sqrt function. The sqrt function calculates the square root. For example:int x = sqrt(9.0)Will leave x with the value 3, which is the square root of 9.STEP 2Define a function THAT USES PASS BY REFERENCE to take in three double inputs and provides two double outputs. In the equations below I use a, b, and c as the double input names and x1 and x2 as the output names.Inside this function solve the quadratic equation for both possible values of x:X 1 = b + b 2 4 a c 2 aThat is, X1 is equal to -b + sqrt(b * b - 4 * a * c) then divide all of that by 2 * a.X 2 = b b 2 4 a c 2 aThat is, X2 is equal to -b - sqrt(b * b - 4 * a * c) then divide all of that by 2 * a.Note the difference. One adds sqrt(b * b - 4 * a * c) and the other subtracts it.This can be done in several lines of code if you want or you can attempt to perform the entire calculation in one line of code.STEP 3In the main function read in 3 inputs from the user. Pass these inputs to the quadratic equation function along with the pass by reference variables for the output. Print the results to the screen.AdviceYour quadratic equation function does NOT need to account for imaginary numbers. Stick with the example inputs to test your code.If you get NAN that means your equation has an imaginary solution. Do not worry about it. Try different inputs.The calculation itself is a minor portion of this grade. The majority of the grade comes from implementing pass by reference so make sure you have that part correct.b2 is simple enough that you do not need to call the pow() function to calculate the power. Instead multiply b * b.You may want to calculate the numerator into one variable and the denominator into another. You don't have to solve the entire equation on one line (though that is possible).Since you are using pass by reference you can make the QuadraticEquation function into a void function. It does not need to return anything since it is returning calculations via pointers.Use scanf on one variable at a time. Don't forget to use double data types and %lf with scanf.
