The sharadze family is planning a car trip to atlanta, georgia, which is 279 miles from their home. they plan to drive at an average speed of 62 miles per hour. they also plan to stop for lunch for 45 minutes. based on their plan, when should they leave in order to arrive in atlanta at 3:00 p.m.?

The Sharadaze family should leave at 10:45 am. 

279(miles)/62(miles)=4.5(min.)  4.5(min.)-45(min.)=4.15

10:45+4:15=2:60 which is 3:00

which proves that the Sharadaze family should leave at 10:45 am.

The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units

Answer:

V = 4187 cubic units.

Step-by-step explanation:

Volume of a sphere = 4/3*π*r^3

Given: r = 10, π = 3.14

Volume of the sphere = 4/3*3.14*10^3

= 4/3*3.14*1000

= 4/3*3140

= 12560/3

V = 4186.66

When we round to the nearest whole number, we get V = 4187 cubic units.

Hope this will helpful.

Thank you.

Nina mixed 16 ounces of olive oil with vinegar to make salad dressing. How many cups of oil did Nina use? (1 cup = 8 ounces) A. 128 cups B. 8 cups C. 2 cups D. 1 cup

Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.

y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.

QUESTION POSTED AT 31/03/2020 - 10:45 AM

What is the area of a circle with circumference of 37.68? (Use 3.14 for p.)

The area of a circle is pi * r^2
circumference is 2 * pi * r

so we have to make the other side look like what area equals:
c = 2pr

divide both sides by 2

c/2 = p* r

square both sides and get
(c^2)/4 = p^2 * r^2

now divide both sides by pi and get
(c^2)/(4*pi) = pi * r^2

compare to area equation
pi * r^2 = a
pi * r^2 = (c^2)/(4*pi)

So
a = (c^2)/(4*pi)

So
a = (37.68^2)/(4 * 3.14)
a = 113.04

Over the last 12 month, Petco has lost a total of $1824.00 due to shoplifting. Write and solve an equation that shows how much money Petco lost each month. ( Since they have lost the money, remember that you need to use negative integers to represent the situation correctly.)

Take y=mx+b  
let x=years and 
y=lost money

then divide 1824 by 12 = 152
and since it is a loss make it into -152
and insert it for m as the constant rate of loss per month
your answer should be y=-152x.
if the store has a starting amount of money plug that into b.

Find the area of the shaded portion of the diagram (use 3.14 for p).A)220.16 square yardsB)6.88 square yardsC)55.04 square yardsD)13.76 square yards

Get the area of the circle. Use this formula: 
Area =  \pi * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is
Area = side^2

Area = 8^2
Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, 
D) 13.76 square yards is the answer to this question.

A shelf holds 3 novels, 2 biographies, and 1 history book. Two students in turns choose a book at random. What is the probability of that the students choose each of the following? 1. both novels _____ 2.both biographies _______ 3. a history, then a novel _____ 4. both history books ______

I'll do the first one:
Both novels.

Student 1 picks a novel. There are 3 novels out of 6 books total.

Now there are 5 books left.

Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.

To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.

 \frac{3 Novels}{6 Books} x  \frac{2 Novels}{5 Books} =   \frac{6}{30} =  \frac{1}{5}

So the probability is 1/5. Or 20%

A = P(1+r)^t  where P is the principal (starting) amount, r is the rate of interest, and t is time. Knowing this, plug in your values:

A = 3,000(1+0.025)^4 < this is what your equation should look like. Once you enter this into a calculator, you should get an answer of $3,311.438672. Round, and you'll be finished.

Nigel and Mia are searching for a treasure chest under water. The straight line distance between them is 100 meters. Given the angles in the diagram, who is closer to the treasure chest and why? a) Nigel is closer because his distance to the chest is opposite the larger angle. b) Mia is closer because her distance to the chest is opposite the smaller angle. c) Nigel is closer because his distance from the chest is 100 meters. d) Mia is closer because her distance from the chest is 100 meters.

The answer is b) Mia is closer because her distance to the chest is opposite the smaller angle.

In the relationship of triangle sides and its angles, the shortest side will always be opposite to the smallest interior angle. Furthermore, the largest side will always be opposite to the largest interior angle. Since Mia's distance to the treasure chest is opposite to the smaller angle 65
°, then she is much closer to the chest.

QUESTION POSTED AT 30/03/2020 - 01:30 AM

Consider the vector v=(-7,8). What is the angle between v=(-7,8) and the positive x-axis? Part 1: Use the formula v1 x v2=|v1||v2|cos theta to find the cosine of the angle between the two vectors (-7,8) and (1,0).

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°
Solving for angle between v and positive x-axis:
180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ
Calculating for the dot product of the vector:
v1 x v2 = -7*1 + 8*0 = -7
Calculating vector magnitude:
|v1| = √(-7²+8²) = √113
|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659
