Answer:
1X10^6
or
1.04x10^6
Step-by-step explanation:
You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

Step-by-step explanation:
Considering the area of the 2 right angled triangles
Area of two triangles
=2 [1/2 x base x height]
=base x height
=8 x 6
=48 ft2
Area of two big rectangles
=2 [length x width]
=2 [10 x 7]
=2 x 70
=140 ft2
Area of small rectangle (base of figure)

Find the values of x and y.
Answer:
x = 15; y = 17
Step-by-step explanation:
A line equals 180 degrees
7x + 7 and 4y form the full line
As such:
7x + 7 + 4y = 180
Another line formation is between 4y and 112
A line equals 180 degrees
4y + 112 = 180
180 = 180 so:
7x + 7 + 4y = 4y + 112
Isolate the variable x
Subtract 4y from both sides
7x + 7 + 4y - 4y = 4y - 4y + 112
7x + 7 = 112
Subtract both sides by 7
7x + 7 - 7 = 112 - 7
7x = 105
Divide both sides by 7
7x ÷ 7 ÷ = 105 ÷ 7
1x = 15
x = 15
If x = 15, plug this new information into the expression with both x and y variables
7(15) + 7 + 4y = 180
Pemdas says multiply first
105 + 7 + 4y = 180
Combine like terms
112 + 4y = 180
Subtract both sides by 112
112 - 112 + 4y = 180 - 112
4y = 68
Divide both sides by 4
4y ÷ 4 = 68 ÷ 4
1y = 17
y = 17
Check work:
7(15) + 7 + 4(17) = 180
Pemdas says multiply first
105 + 7 + 68 = 180
Combine like terms
112 + 68 = 180
180 = 180
This means the variable values are correct

Write an equation that relates the time, t, it takes to travel a given distance, d.
The equation that relates the time, t, it takes to travel a given distance, d is d = rt
What is Speed?This is a scalar quantity and can be defined as the magnitude of the rate of change of its position with time.
d = rt
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t = d/r
This is why it was chosen as the most appropriate choice.

Rectangle ABCD has a perimeter of 22 units. The coordinates of the rectangle's vertices are A(-4,5), B(3,x), and D(-4,x). Which could be the value of x
Through the given information in the question, the value of x could be 12.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance around the outside of the rectangle. It is calculated by adding together the length of all four sides of the rectangle. If the length of the rectangle is denoted by 'l' and the width is denoted by 'w', then the formula for the perimeter (P) of the rectangle is:
P = 2l + 2w
Alternatively, the formula can also be written as:
P = 2(l + w)
The perimeter of a rectangle is given by the sum of the lengths of all four sides. Therefore, we can write:
AB + BC + CD + DA = 22
We know that AB = CD = 9 since they are opposite sides of the rectangle. We also know that DA = BC = x - 5, since they are the other two sides of the rectangle.
Substituting these values into the perimeter equation, we get:
9 + x - 5 + 9 + x - 5 = 22
Simplifying the equation, we get:
2x - 2 = 22
2x = 24
x = 12
Therefore, the value of x could be 12.

Shen runs 7 miles in 50 minutes. At the same rate, how many miles would he run in 75 minutes?
Answer:
(7 miles)/(50 minutes) = (x miles)/(75 minutes)
7/50 = x/75
7*75 = 50x
525 = 50x
50x = 525
x = 525/50
x = 10.5
He can run 10.5 miles in 75 minutes
Step-by-step explanation:
Answer:
10 [tex]\frac{1}{2}[/tex] miles in 75 minutes.
Step-by-step explanation:
Let us first analyze the problem,
we are given that she runs 7 miles in 50 mins
make it a fraction
[tex]\frac{7}{50}= \frac{x}{75}[/tex] (we cross multiply)
525=50x (divide both sides by 50)
x=10.5 (x= the amount of miles)
If a, b, and c are rational numbers and ac>bc always true?
Answer:
Let's put it like this.
a = 1
b = 2
c = 3
Now, multiply b and a.
a x c = 3
Convert this expression to its factored version, ac.
Next, multiply b and c.
b x c = 6
Turn b and c into factored form, bc.
↓ conclusion ↓
Since 6 is greater than 3, this statement is not true. The only way it will always be true is if you reversed the number sequence to be greatest to least, instead of least to greatest.

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly. How much more will Viola’s monthly payment be if the loan is unsubsidized than if the loan is subsidized? Round all dollar values to the nearest cent. A. $35. 05 b. $45. 94 c. $96. 96 d. $63. 52.
The Viola’s monthly payment more than the loan is unsubsidized than if the loan is subsidized is $35.05.
What is compound interest?Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,
[tex]A=P\left(1+\dfrac{R}{n\times100}\right)^{nt}[/tex]
Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.
Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly.
Put this values in the above formula as,
[tex]A=8470\left(1+\dfrac{7.5}{12\times100}\right)^{12\times 4}\\A=11422.6348[/tex]
For the four years, the monthly payment is,
[tex]m=\dfrac{11422.6348}{4}\\m=237.97[/tex]
The monthly payment of unsubsidized loan is $237.97.
The monthly payment of subsidized loan is $202.80.
The difference between the unsubsidized and subsidized loan monthly payment is,
[tex]d=237.97-202.80\\d=35.17\\d\approx35.05[/tex]
Thus, the Viola’s monthly payment more than the loan is unsubsidized than if the loan is subsidized is $35.05.

Answer:
x = -15
Step-by-step explanation:
It appears the drawing is showing two representations for the distance LK. Of course, they both have the same value.
10 = LK = x+25
Subtracting 25 from the equation, we have ...
-15 = x
(This value of x makes KJ = (2(-15)+27) = -3, a nonsense value.)
_____
Alternate (more sensible) interpretation
If the bottom line is intended to represent LJ, then we have ...
10 +(2x+27) = (x +25) . . . . LK +KJ = LJ
x +37 = 25 . . . . subtract x
x = -12 . . . . . . . subtract 37
With this value of x, the length of KJ is 2(-12)+27 = 3, and the overall length LJ is (-12)+25 = 13. This is consistent: LK=10, KJ = 3, LJ = 13.

What is the measure of angle 1? A triangle has angles 29 degrees, 65 degrees, and 2. The exterior angle to angle 2 is 1. 36° 86° 89° 94°.
Answer:

Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angles.
∠1 = 29° +65° = 94°

Additional comment
You can see this when you realize that both the sum of the remote angles and the exterior angle are supplementary to the third interior angle, ∠2. Angles supplementary to the same angle are congruent. That is, the sum of 29° and 65° is congruent to ∠1.
