Answer:
1.578 × 109 inches
Step-by-step explanation:
Multiply the diameter of one red blood cell by the number of red blood cells to determine the length of the chain.
First, write both numbers in scientific notation.
Now, multiply using the product property of exponents.
Since the first term of a number written in scientific notation must be greater than 1 and less than 10, rewrite 15.78 × 109 as 1.578 × 109.
So, the length of the chain of red blood cells would be about 1.578 × 109 inches long.
Evaluate the expression [(18 ÷ 2 + 54 ÷ 9) × 2] × 2.

An independent-samples t test was conducted to compare high-altitude exercise to exercise at sea-level. Imagine the mean comfort level of participants, rated on a 7-point scale where high values reflect high comfort, at high altitude was 3.5 while the average at sea-level was 5.1. Imagine also that values were calculated for sdifference of 1.1, 2.04 for pooled variance, and 35 for degrees of freedom total. What are the critical cutoffs for this test
Answer:
-2.03, 2.03
Step-by-step explanation:
The degree of freedom (df) ;
Df total for the two samples = 35
Therefore, obtuaking the critical value using a T-test distribution at 95% confidence level.
(1 - 95%) / 2 = (1 - 0.95) / 2 = 0.05 / 2 = 0.025
Using a T critical value calculator or t table distribution ;
Tcritical, 0.025, df = 35 = 2.03
Left tail = - 2.03
Right = 2.03
Hence, critical cutoff :
(-2.03 ; 2.03)

What is the area of this trapezoid?
Answer: 6625 sqaure yards
Step-by-step explanation:
Area for a trapezoid formula is A=(base 1 + base 2)·height÷2
So base one is 120 and base two is 10+120+15=145
and the height is 50 so (120+145)·50÷2=6625 The area for the trapezoid is 6625

Mr.Nolan paid $36.95 for each adult shirt and $23.95 for each youth shirt he bought.Mr.Nolan bought 2 adult shirts and 5 youth shirts.
Answer:
Mr.Nolan paid $193.65 in total for the shirts
Step-by-step explanation:
$36.95 (how much one adult shirt costs) x 2 shirts = $73.90
$23.95 (how much one youth shirt costs) x 5 shirts = $119.75
$119.75 (youth shirts total costs) + $73.90 (adult shirts total cost) = $193.65
Mr.Nolan paid $193.65 for the 2 adult shirts and 5 youth shirts.

After 1 year, $1,000 deposited in a savings account with simple interest had earned $30 in interest. What was the interest rate?
Answer:
3%
Step-by-step explanation:
The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.
I = PRT
30 = (1000)(R)(1)
30 = 1000R
R = 0.03
Multiply by 100 to get the percentage of 3%

Phillip decides to invest $800,000 in a period annuity that earns 5.2% APR
compounded monthly for a period of 20 years. How much money will Phillip
be paid each month?
A. $6159.31
B. $5368.43
C. $5200.00
D. $6389.29
The compounded amount after 10 years would be $1,458,293.87.
What is the formula to calculate the compound interest?The formula to calculate the compound interest is -
[tex]$A =P(1 + \frac{r}{n}) ^{nt}[/tex]
Given is that Phillip decides to invest $800,000 in a period annuity that earns 5.2% APR compounded monthly for a period of 20 years.
We can calculate the compounded amount as -
A = 800000(1 + 0.052/12)^(12 x 20)
A = 1,458,293.87
Therefore, the compounded amount after 10 years would be $1,458,293.87.

Answer:
Perimeter of figure = 36.3
Step-by-step explanation:
We'll begin by calculating the perimeter of the rectangle. This can be obtained as follow:
Length (L) = 9
Width (W = 4
Perimeter of rectangle (Pᵣ) =?
Pᵣ = 2(L + W)
Pᵣ = 2(9 + 4)
Pᵣ = 2(13)
Pᵣ = 26
Next, we shall determine the perimeter of semi circle. This can be obtained as follow:
Diameter (d) = 4
Pi (π) = 3.14
Perimeter of semi circle (Pₛ) =?
Pₛ = ½(πd) + d
Pₛ = ½(3.14 × 4) + 4
Pₛ = ½(12.56) + 4
Pₛ = 6.28 + 4
Pₛ = 10.28
Finally, we shall determine the perimeter of the figure. This can be obtained as follow:
Perimeter of rectangle (Pᵣ) = 26
Perimeter of semi circle (Pₛ) = 10.28
Perimeter of figure =?
Perimeter of figure = Pᵣ + Pₛ
Perimeter of figure = 26 + 10.28
Perimeter of figure = 36.28 ≈ 36.3

Candice bought 3 shirts. Each shirt cost the same amount and was discounted by $3.66.
Candice paid a total of $62.31 before tax. How much did each shirt cost before the discount?
А $19.55
B
$20.77
С
$24.43
D
$28.09
Answer:
Let the cost of each shirt be s.
Would assume each shirt was discounted by 3.66
Amount to be paid for each: s - 3.66
Total = 3*(s - 3.66)
3*(s - 3.66) = 62.31
s - 3.66 = 62.31/3
s - 3.66 = 20.77
s = 20.77 + 3.66
s = 24.43
Each shirt cost $24.43 before the discount.

Jane planted a marigold sapling in her garden and recorded its growth every week. The plant's height, in inches, is modeled by the function hig),
where x is the number of weeks since Jane planted the sapling.
Answer:
The function is increasing, but the average rate of change is decreasing.
Step-by-step explanation:
I used a graphing calculator good luck on your exam my fellow edmentum user.
The true statement is (c) the function is increasing, but the average rate of change decreases
How to determine the true statement?From the function table of values, we have the following highlights
The x values increaseThe values of f(x) also increaseThe above means that the function is increasing
Next, we calculate the average rates of change:
At interval x = [0,1], the average rate of change is:
Rate = (8.49 - 3)/(1- 0) = 5.49
At interval x = [1,2], the average rate of change is:
Rate = (11.62 - 8.49)/(2- 1) = 3.13
The above shows that the average rate of change decreases
Hence, the true statement is (c) the function is increasing, but the average rate of change decreases

there are 16 students working on a project if each student need 1/4 stick of clay are needed in all?
Answer:
4 sticks of clay
Step-by-step explanation:
To find the total amount of clay needed, multiply the number of students by the amount need for each one of them.
[tex]16[/tex] · [tex]\frac{1}{4}[/tex]
Multiply these by converting 16 into a fraction.
[tex]\frac{16}{1}[/tex] · [tex]\frac{1}{4}[/tex]
Multiply the numerators and denominators across.
[tex]\frac{16}{1}[/tex] · [tex]\frac{1}{4}=\frac{16}{4}[/tex]
Simplify this.
[tex]\frac{16}{4} =4[/tex]
The total amount of clay needed is 4 sticks.

Which of the following statements best describes the diagram below?
a. The intersection of two planes is a line.
b. The intersection of two points is a line.
C. Two points can be contained in two planes.
d. Two points can intersect at two planes.
The statement first “The intersection of two planes is a line." option (a) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two planes, Y and Z intersecting each other.
The intersection of two lines is a point.
As we know, if the two planes intersect each other, the intersection will be a line.
If planes are parallel then there will no intersection.
Thus, the statement first “The intersection of two planes is a line." option (a) is correct.
