An automobile traveled 106 miles in 2 hours. What was average speed? Use the formula d = rt .104 mph
0.02 mph
53 mph
108 mph
212 mph

Answers

Answer 1
Answer:

The average speed of the automobile is 53mph.

Description of average speed

Average speed is the total distance travelled by the automobile (106 miles) divided by the total hours travelled by the automobile (2 hours). It is the rate of the movement of the automobile.

Determining the average speed

Average speed = total distance travelled / total time travelled

106 / 2 = 53 mph

The volume of an object is given as a function of time by V = A + B t + C t4 . Find the dimension of the constant C

Answers

Answer:

The dimensions of constant C are of [L^(3)T]^(-4)

Step-by-step explanation:

It is given that

V(t)=A+Bt+Ct^(3)

Since the dimensions of volume are [L^(3)]

Each of the term shall have a dimension of [L^(3)] since they are in addition.

Thus for third term we can write

Thus we have

[L^(3)]=[C][T^(4)]\n\n\therefore [C]=[L^(3)][T^(-4)]

A line with a slope of -2 passes through the point (4, 7). Write an equation for this line in point-slope form.

Answers

Answer:

The equation in point-slope is y-7=-2(x-4).

Step-by-step explanation:

Point-slope is a specific form of linear equations in two variables:

y-b=m(x-a)

When an equation is written in this form, m gives the slope of the line and (a, b) is a point the line passes through.

We want to find the equation of the line that passes through (4, 7) and whose slope is -2. Well, we simply plug m = -2, a = 4, and b = 7 into point-slope form.

y-7=-2(x-4)

\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{7})~\hspace{10em} slope = m\implies -2 \n\n\n \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\n \cline{1-1} \n y-y_1=m(x-x_1) \n\n \cline{1-1} \end{array}\implies y-7=-2(x-4)

The Singh family ordered a large pizza with a diameter of 20 inches for dinner. If one of the members of the family ate one eighth of the pizza, how many square inches of pizza are remaining? Use 3.14 for π.274.75 square inches
39.25 square inches
314 square inches
157 square inches

Answers

274.75 square inches of pizza are remaining. Option A is the correct option.

What is π in math?

The ratio of a circle's diameter to its circumference, or "pi," is a mathematical constant that is roughly equal to 3.14159 (/pa/; also written as "pi"). Numerous mathematical and physics formulas contain the number. It is an irrational number, meaning that although fractions like 22/7 are frequently used to approximate it, it cannot be expressed exactly as a ratio of two integers.

Given that, the diameter of large pizza is 20 inches.

The radius of a circular shape is half of the diameter.

The radius of the pizza is (20 inches)/2 = 10 inches.

Area of a circular shape is ∏r² .

The area of the pizza is 3.14×10² = 314 in²

The total part of the pizza is considered as 1.

One-eighth of the pizza is eaten, and the remaining portion is (1-1/8) = 7/8.

The area of remaining pizza is

314 in²  × (7/8)

= 274.75 square inches

The amount is 2.88 is ( percent of what price?

Answers

Answer:

Discount = Original Price x Discount %/100

Discount = 2.88 × 1/100

Discount = 2.88 x 0.01

You save = $0.03

Final Price = Original Price - Discount

Final Price = 2.88 - 0.0288

Final Price = $2.85
