Car A travels 60 miles in 2 hours. The distance car
B travels is given by the equation where d is the
distance, in miles, that car B travels in t hours.
Based on this information, which statement is true?
The speed of Car A when it travels 60 miles in 2 hours is 30 miles per hour. This is the rate. Therefore, that is true.
How to illustrate the rate?From the information, it should be noted that Car A travels 60 miles in 2 hours. It should be noted speed is calculated as:
Speed = Distance / Time
It should be noted that speed simply means the distance that's travelled with respect to time.
Speed = 60 / 2
Speed = 30 miles per hour

There is a close relationship between the air pressure inside a hurricane and its maximum
sustained wind speed: y = -0.932x + 973 where x is the air pressure in millibars (kPa) and y is the
wind speed in knots (nautical miles per hour).
The wind speed when the air pressure is 20kpa will be 954.36 miles per hour.
How to illustrate the information?From the information, there is a close relationship between the air pressure inside a hurricane and its maximum sustained wind speed: y = -0.932x + 973.
where x = the air pressure in millibars (kPa) l
y = wind speed in knots (nautical miles per hour).
Therefore, the wind speed when the air pressure is 20kpa will be calculated thus:
y = -0.932x + 973.
y = -0.932(20) + 973.
y = -18.64 + 973

write 5 to the power of -3 in its simplest form without any indices
lol this is annoying
5 to the power of -3 in its simplest form without any indices is 1/125 or 0.008.
Exponents
Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. For example, 6 is multiplied by itself 4 times, i.e. 6 × 6 × 6 × 6. This can be written as [tex]6^4[/tex]. Here, 4 is the exponent and 6 is the base. This can be read as 6 is raised to power 4.
We know that,
[tex]a^{-b}=\frac{1}{a^b}[/tex]
Hence, we can write,
[tex]5^{-3}=\frac{1}{5^3}[/tex]
We know that the cube of 5 is 125.
Hence, we can write,
[tex]\frac{1}{5^3}[/tex] = 1/125
1/125 is the simplest form of fraction and is equal to 0.008 in decimal form.

The equation of the line graph in slope intercept form is gotten as;
y = x + 3
What is the equation of the Line in Slope Intercept Form?The general formula for the equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Now, from the given straight line equation graph, we can see that the line crosses the x-intercept at x = -3 and crosses the y-intercept at y = 3. Thus;
When x = 0, y = 3
When y = 0, x = -3
Slope is gotten by using two points and their coordinates to get;
m = (3 - 0)/(0 - (-3))
m = 3/3
m = 1
Thus, the equation of the line is y = x + 3

The diagram shows a semi-circle inside a rectangle of length 150 m.
The semi-circle touches the rectangle at A, B and C.
Calculate the PERIMETER of the shaded region. Give your answer correct to 3 significant figures. Ive worked out everything so far but im missing a mark
The diagram shows a semi-circle inside a rectangle of length 150 m.
The semi-circle touches the rectangle at A, B and C, the perimeter of shaded region is 267.8m
Perimeter of a circle = 2 πr
Thus, as per the diagram given:
Length of rectangle = 150 m
The radius of semi circle = half of 150 m = 75 m
So, the width of the circle is same as radius = 75 m
The shaded region is bounded by the circumference of a quarter circle (AB) and the two sides measuring it are 75 m each.
Perimeter of Quarter circle = 2πr
On substituting r
Perimeter of Quarter circle = 2π x 75
Perimeter of the shaded region = 117 + 75 + 75 = 267.8 m
The diagram shows a semi-circle inside a rectangle of length 150 m. The semi-circle touches the rectangle at A, B and C, the perimeter of the shaded region is 267.8m

Answer:

Step-by-step explanation:
Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.
Given piecewise function:
[tex]f(x)=\begin{cases}2x \quad &\text{if }x < 1\\5 \quad &\text{if }x=1\\x^2 \quad &\text{if }x > 1\end{cases}[/tex]
Therefore, the function has three definitions:

This statement is true as when x = 1, f(x) = 5.
[tex]\textsf{B.} \quad f(5)=1[/tex]
This statement is false as when x is greater than 1, f(x) = x²:

This statement is true as when x is greater than 1, f(x) = x²:

Step-by-step explanation:
Fixed costs = $ 1329.50 per month
Variable cost are $3.70 per set of napkins
Total cost she set aside = $1870 for monthly costs
Amount left for napkins = Total cost - Fixed Cost
= 1870 - 1329.50
= $540.50
$540.50 she can spend on napkinsCost for one set = $3.70
Let set of napkins = x
Total cost for napkins = $540.50
x × 3.7 = 540.50 x = 540.50 / 3.70x = 146.08 (approx) or 147 setsTherefore , she can afford to make 147 (approx) sets of napkins per month.

Patients in a study about a new medication were asked to rate their symptoms on a scale from 1 to 10 each hour, over a period of 8 hours after taking the medication. On the given scale, 1 represents symptoms being the least bothersome, and 10 represents them being the most bothersome. It is found that over this time period, the function y=0.5x2−3.6x+8.9 best models the patient's rating y, x hours after taking the medication.
What is the predicted rating 2.5 hours after taking a dose? Round your answer to two decimal places.
It is to be noted that the predicted rating after taking a dose in two decimal places is 5.53. See the explanation below.
What is the explanation for the above answer?Recall that we are given the expression:
y= 0.5x²−3.6x+8.9 .......................function 1
After 2.5 hours,
Predicted Rating (y) =
0.5 (2.5)² - 2.6 (2.5) + 8.9 [Substitute x into the function]
y= 0.5 (6.25) - 2.6 (2.5) + 8.9 [Expand the brackets]
y= 3.125 - 6.5 + 8.9
y= 5.525

three cards are drwan at random, without replacement, from a standard deck of 52 playing cards. compute the (conditional) probability that the first card drawn is spade, given that the second and third cards have spades.
If the second and third cards have a spade then the probability that the first card drawn is a spade is 21.2%.
Probability can be described as a field of mathematics that determines how likely a thing is to happen. When there is uncertainty about the outcome of an event we consider the probabilities of certain results or outcomes.
There are a total of 13 spades in a deck of 52 playing cards. So if the second and third cards have spades then there are 11 spades remaining.
The formula for probability can be given as;
probability = number of favorable outcomes or events ÷ total number of outcomes or events
probability = 11 / 52 = 0.212
Converting it into percentage;
probability = 0.212 × 100 = 21.2%
Therefore, the probability that the first card drawn is a spade is calculated to be 21.2%.
