Answer/Step-by-step explanation:
A. Distance travelled at constant rate = 180 miles
Rate of travel (r) = distance travelled (d) /time (t)
Travel time (hrs) ==> rate of travel (miles/hr)
5 ==> 180/5 = 36
4.5 ==> 180/4.5 = 40
3 ==> 180/3 = 60
2.25 ==> 180/2.25 = 80
B. t = time travelled in hrs,
r = rate (miles/hr)
d = distance travelled = 180
Therefore, rate travelled for t hours would be:
[tex] r = \frac{180}{t} [/tex]
The rate of travel gives the average speed the car will be going if it covers
the 180 miles in different times
Part 1. The table showing the rate at which the car was going is presented as follows;
[tex]\begin{array}{|c|cc|} \underline{\mathbf{Travel \ time, \, t\ (hours)}}&&\underline{\mathbf{Rate \ of \ travel \ (miles \ per \ hour)}}\\&&\\5&&36\\&&\\4.5&&40\\&&\\3&&60\\&&\\2.25&&80\end{array}\right][/tex]
Part 2. To make it easy to find the rate of travel, the following equation may be uses;
[tex]\underline{The \ rate \ of \ travel= \dfrac{180 \ miles}{t \ hours}}[/tex]Reasons:
Part 1.
The given distance travelled by the car = 180 miles
[tex]The \ rate \ of \ travel= \dfrac{Distance \ traveled}{Time \ taken}[/tex]
Therefore, we have;
[tex]\begin{array}{|c|c|c|} \underline{\mathbf{Travel \ time, \, t\ (hours)}}&\underline{\mathbf{Rate=\dfrac{180}{t} } }&\underline{\mathbf{Rate \ of \ travel \ (miles \ per \ hour)}}\\&&\\5&\dfrac{180}{5} = 36&36\\&&\\4.5&\dfrac{180}{4.5} = 40&40\\&&\\3&\dfrac{180}{3} = 60&60\\&&\\2.25&\dfrac{180}{2.25} = 80&80\end{array}\right][/tex]
Part 2.
The equation that would simplify the finding of the car's travel rate is given
by the following expression;
[tex]The \ rate \ of \ travel= \dfrac{Distance \ traveled}{Time \ taken}[/tex]
Where:
The constant distance traveled = 180 miles
The time taken = t
The equation that will make finding the rate of travel, easy in therefore;
[tex]\underline{The \ rate \ of \ travel= \dfrac{180 \ miles}{t \ hours}}[/tex]

What is the area of this triangle? And it's not 60, I already checked. PLEASE EXPLAIN!!!!
Answer:
A = 4 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 b*h
The base is 4 and the height is 2
A = 1/2 ( 4*2)
A = 1/2*8
A = 4 cm^2
Answer:
4
Step-by-step explanation:
A = BH/2
or Area = Base multiplied by Hieght divided by 2.

Need help ASAP!! Tysm
Answer:
60 cm
Step-by-step explanation:
remember, the area of a triangle is found by
1/2 b h
or half of the base times the height
so using that plug in the values:
the base is made of two 5s; 2* 5 is 10 so the base is 10cm long
the height is 12cm
so
1/2 * 12 * 10
= 6 * 10
= 60
Answer:
I think its 60
Step-by-step explanation:
To find the area of a triangle you do (height x base) divided by 2
5+5=10
12 x 10 = 120
120 divided by 2 is 60
A student worked out an equation and below is his solution. is the answer correct? If not, where was the error and what is the correct answer?
-4(6-r)=12
-24-4R=12
-4R=36
R=-9
Answer:
His answer is wrong.
Step-by-step explanation:
-4(6-R)=12 <-- Since R is negative, -4 times -R results in a positive so, 4R.
-24+4R=12
+24 +24

What is the value of the expression (x – 2y) (x + 2y) when x= 4 and y=1/2
Answer:
15
Step-by-step explanation:
First you would plug in the 4 and 1/2 in the x and y's places, making the expression (4 - 2 (1/2))*(4 + 2 (1/2). Then you solve (below).
(4 - 2 (1/2))*(4 + 2 (1/2)
(4 - 1)*(4 + 1)
(3)*(5)

The mean weight of the 28 bears at a zoo is 413 pounds. Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo. What is the new mean of the weight of the bears at the zoo? Round your answer to the nearest tenth and enter pounds in the units box.
Answer:
416.8 pounds.
Step-by-step explanation:
The mean weight of the 28 bears at a zoo is 413 pounds.
The Total Weight of the 28 bears = Mean weight × number of bears
= 413 pounds × 28 bears
= 11564 pounds
Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.
This means the total number of bears
= 30 bears because two additional bears were added
What is the new mean of the weight of the bears at the zoo?
New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears
= 12503 pounds /30 bears
= 416.76666667 pounds
Approximately to the nearest tenth = 416.8 pounds.

Given the quadratic function f(x) = (x + 6)(x – 3):
The x-intercepts are
The y-intercept is
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = (x + 6)(x - 3)
For x-intercept,
Substitute the value f(x) = 0.
(x + 6)(x - 3 = 0
x = 3, -6
So the x-intercepts will be,
(-6, 0) and (3, 0)
For y-intercept,
Substitute the value for x = 0,
f(0) = (0 + 6)(0 - 3)
= -18
Therefore, y-intercept of the given quadratic function will be (0, -18).
-4p+(-6p) combine like terms to create an equivalent expression
Answer:
-10p
Step-by-step explanation:
-4p+(-6p) for me I like to think of the negative or subtraction sign
overpowering the positive or addition sign
so in this case
-4p-6p
then since the variable p is the same -4-6 is -10
the end result is -10p
