O A. Area of the base
B. Perimeter of the base
C. Length of the base
O D. Volume of the base
Answers
Answer:
A.Area of the base
Step-by-step explanation:
these is obtained by multiplying the length and width of the base to get the area of the base
The variable B in the Formula is area of Base.
What is Volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Pyramid volumes are measured by how much space they take up or by how many unit cubes can fit inside of them. A pyramid is a polyhedron because it has polygonal faces.
As, Volume of pyramid = (1/3) (Bh), where
B = Area of the base of the pyramid
h = Height of the pyramid.
So, B in the Formula is area of Base.

A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount?
Answers
Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)

which is .2
correct me if i am wrong
The probability that a number selected at random from set S above will also be in set T will be 0.2 hence, option (B) will be correct.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Do not take underestimate probability it has several uses in daily life whether forecasts and like that.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Given that the S = {2, 4, 6, 8, 10 and T = {1, 2, 3, 4, 5)
Now there are a total of 10 numbers. The common number among S and T are 2 and 4 only so
Probability = 2/10 = 0.2 hence it will be correct.

Two cars are travelling from Toronto to Quebec. Car A left Toronto at 8 a.m. and is moving with an average speed of 70 km/h. Car B left Toronto at 10 a.m. and its average speed is 90 km/h. How many hours will it take for car B to catch car A?
(please show all your work Let, So, Equation and Solution and Therefore Statement)
Answers
Answer:
It'll take 7 hours for the car B to cath up to A
Step-by-step explanation:
In order to solve this problem we can write the equation from the distance of each car. Assuming that t = 0 happens when the second car leaves Toronto. When the second car leaves Toronto, the first one is on the road for two hours already, thefeore it travelled a total of:
distance = speed*time = 70*2 = 140
We have:
Car A:
x(t) = 70*t + 140
Car B:
x(t) = 90*t
We now need to find the value of "t" that makes x(t) the same for both cars:
90*t = 70*t + 140
20*t = 140
t = 140 / 20 = 7 h

If Sue worked 7 1/4 hours on Monday, 3 hours on Tuesday, 6 3/4 hours on Wednesday, 8 hours on Thursday, and 5 hours on Friday, calculate her weekly wage at $4.10 per hour
Answers
Answer:
$123
Step-by-step explanation:
Let's find the total amount of hours Sue worked. To do so, we'll do 7.25 + 3 + 6.75 + 8 + 5 = 30 total hours. Now, we'll multiply 4.1 by 30 because she receives $4.10 for every hour. 4.1 * 30 = $123. Hope this helps!
josh allowance is m cents per week. Represent the number of dollars he gets in a year.
a) 3m/25
b) 1200m
c) 13m/25
d) 25m/13
Answers
Answer:
The number of $ Josh receives in a year should be 13m / 25
Step-by-step explanation:
This is quite a simple a question.
Consider how many weeks there are in a year. Well there are about 52 weeks, you can say. Knowing that, you could apply the following conversion factor -
[tex]\frac{52 ( weeks ) }{ 1 ( year )}[/tex] ... at the same time we have to consider how many cents there are in a dollar. There are 100 cents, giving us the conversion factor [tex]\frac{1 ( dollar )}{100 ( cents )}[/tex]. Therefore, Josh's allowance should be, after 1 year -
m [tex]*[/tex] [tex]\frac{52}{1}[/tex] [tex]*[/tex] [tex]\frac{1}{100}[/tex]
= [tex]\frac{52m}{100}[/tex] - Which, simplified, = [tex]\frac{13m}{25}[/tex].
Our solution here is option c, rather option d.
The number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We have:
Josh's allowance is m cents per week.
As we know,
Total number of weeks in a year = 52 weeks
In 1 dollar there are 100 cents
josh's allowance is m cents per week
The number of dollars he gets in a year = (52/100)m
After simplification:
The number of dollars he gets in a year = 13m/25
Thus, the number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.

Step-by-step explanation:
y = 2x + 3
substituting : 5 = 2(2) + 3
5 = 4 + 3
5 = 7, this is false, therefore (2,5) is NOT a solution
Answer:
A linear equation's solution would be a coordinate when the value of x and y satisfies the equation.
For Example:
[tex](1,7)[/tex] will be a solution to the equation [tex]y=3x+4[/tex], because if you replace x and y with one and seven it satisfies the equation.
[tex]y=3x+4\\y=7 \\x=1\\\text {Solve: }\\7=3(1)+4\\\rightarrow3*1=3\\7=3+4\\\boxed {7=7}[/tex]
[tex](1,7)[/tex] also lies on the equation's line.

109 109 90 81 85 94 92 106 110 89 87 94 100 90
Assume that the hay fever rate in each age group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use α =0.05. If , will you reject or fail to reject the null hypothesis? Are the data statistically significant at confidence level α?
a
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis.
b
Since the P-value is greater than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.
c
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis.
d
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we fail to reject the null hypothesis.
e
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.
