Wendy was traveling from Baltimore, MD to Cleveland, OH. For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph. Write an expression to model her distance and calculate how far she drove. You may use the distance formula d=r*t (distance = rate * time).
Answer: D = r*t + r*t 372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)
OR
D1 + D2 = Total 173 1/4 + 199 1/2 = 372 3/4
D1 = r1 *t1 63 * 2 3/4 = 173 1/4
D2 = r2 * t2 57 * 3 1/2 = 199 1/2
Step-by-step explanation:
The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.
Another way to write the expression would be D = r*t + r*t
The total distance that Wendy drove to Cleveland will be 372.75 miles.
For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. Then, the distance traveled will be:
= 63 × 2 3/4
= 173.25 miles.
For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph, the distance will be:
= 57 × 3 1/2
= 199.5 miles
The total distance traveled will then be:
= 173.25 miles + 199.5 miles
= 372.75 miles.

So %44 of your class students chose pizza.
The percentage of the class chose pizza = 44%
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For given example,
Total number of students = 25
the number of students who chose pizza as their favorite food = 11
So, the percentage of the class chose pizza would be,

A parabolic heater has a cross section modeled by a parabola with vertex (0,0\right) and focus (2,0\right) . The heater has a depth of 5 inches. What is the width of the parabolic heater at its widest point? Round your answer to the nearest hundredth.
Answer:
y = 6.93
Step-by-step explanation:
Given the Vertex and ficuas of a parabola as :
Vertex (0,0) ; focus(0,2) ; depth = 5 inches
Width of parabolic heater at its widest point :
General equation of a parabola:
4p(x - h) = (y - k)²
(h, k) = Vertex
hence,
h =0 ; k = 0 ; p = 2 ; x = 5
(y - k)² = 4p(x - h)
(y - 0)² = 4*2(6 - 0)
(y-0)(y-0) = 8(6 - 0)
y² = 48 - 0
y² = 48
y = 6.928
y = 6.93

Sam counted his heartbeats while resting. His heart beat 220 times in 4 minutes. Sam's heart beat at the same rate for the 4 minutes.
The equation for the number of beats per minute is 55 beats per minute
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of beats be = A
Now , the value of A = 220 beats
The total time required for Sam to have 220 beats = 4 minutes
So , the number of beats of Sam in 1 minutes is calculated by
The equation will be
The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats
The number of beats of Sam in 1 minute is = 220 / 4
The number of beats of Sam in 1 minute is = 55 beats per minute
Therefore , Sam would have 55 beats every minute or 55 beats per minute
And for the period of 4 minutes , Sam would have
Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4
Number of beats for 4 minutes = 55 x 4
Number of beats for 4 minutes = 220 beats in 4 minutes
Hence , The equation for the number of beats per minute is 55 beats per minute
