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.

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.

Another friend's distance d from you (in feet) after t seconds is given by
d = |80 - 5t|. What does the 80 in the equation represent? What does the 5 in the equation represent? At what times is she 60 ft from you?

Answers

I think the 80 represents how far away they initially start from you

And the 5 is their speed

d=|80-5t|
60=|80-5t| |square both sides
60² = (80-5t)(80-5t)
3600 = 6400-400t-400t +25²
25t²-800t +6400 =3600
25t² -800t + 2800=0
5t² -160t +560=0
(ax²+bx+c=0)
(a=+5 b=-160 c=+560)
Sub into -b formula
x=(-b±√(b²-4ac))/(2a)
t= (-(-160)±√((-160)²-4(5)(560))/(2(5)) .


Should get t=4 seconds and t=28 seconds
sub both values back in to make sure

d=|80-5(4)|
d=|80-20|
d=60ft

d=|80-5(28)|
d=|80-140||
d=60ft

Add  5  to both sides of the equation :

pear is the heaviest, and the strawberry is the lightest

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

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

Answer:

First let's calculate the area of the bottom part

diameter is 34 m

so the radius (r) is 1/2 * 34 m = 17 m

bottom part is 1/2 of a circle

circle surface area formula is πr²

so surface area of our bottom part is 1/2 * πr²

1/2 * πr² = 1/2 * 3,14 * 17² = 453,73

so it's 453,73 m²

Triangle part consists of 2 smaller rectangular triangles

surface area for rectangular triangle is 1/2 * a * h

in our case a = r = 17 m and h = 30m

so one smaller rectangular triangle is 1/2 * r * h = 1/2 * 17 * 30 = 255

so it's 255 m²

and because our entire triangle part consists of 2 smaller rectangular triangles it's area is 2 * 255 m² = 510 m²

Surface area of the entire figure is a sum of 510 m² and  453,73 m²

510 m² +  453,73 m² =  963,73 m²

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

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.
