Last week, Juliet ran 22 kilometers. This week, she plans to run 2\frac{2}{5}2 5 2 times as far as last week. How many kilometers does Juliet plan to run this week?
Answer: 52.8 kilometers
Step-by-step explanation:
This week she plans to run 2²/₅ times as much as last week.
If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.
First convert the improper fraction to a proper one:
2²/₅ = 12/5
= 12/5 * 22
= 264/5
= 52.8 kilometers
In △ A B C , the measure of angle A is 103 ° and the measure of angle B is 37 ° . What is the measure of angle C ?

Answer:
0.225989
Step-by-step explanation:
3x+9+x-11=180
4x-3=180
4x=180-3
4x/4x=177/4x
0.225989
Answer:
=78 degrees
Step-by-step explanation:
complementary angles add up to 90 degrees
A + B = 90
3x + 9 + x - 11 = 90
3x + x + 9 - 11 = 90
4x - 2 = 90
collect like valuables
4x = 90 + 2
4x = 92
x =23
angle A = 3x + 9
= (3 x 23) + 9
= 69 + 9
= 78

Slope-intercept form:
y = mx + b, where m - slope, b - y-interceptWe are given two points on the graph:
(0, 1) and (2, 0)The first point gives us the y-intercept:
b = 1Finding the slope using slope formula:
m = (y2 - y1)/(x2 - x1)m = (0 - 1)/(2 - 0) = -1/2The formula of the line:

The length of a rectangle is 8 inches more than the width. The area of the rectangle is 33 square inches. What is the length of the rectangle?
Step-by-step explanation:
Put x as the width and x+8 as the length. The equation would be x(x+8)=33 and it would factor out as (x-3)(x+11). The width is 3 and the length is 11. The perimeter would be 28.

During the Martinez family trip, they drove from home to a ski lodge, a distance of 52 4 5 miles, and then drove an additional 14 4 5 miles to visit friends.
Answer:
[tex]134 \frac{6}{5}[/tex]
Step-by-step explanation:
The computation of the distance travelled is shown below:
Total distance would be
[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]
Now if the same route would taken again in order to back home
So, the total distance would be doubled
[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]

Answer:
Step-by-step explanation:
Scale factor = 1 : 7
a)Let the length of the house in the scale drawing = x
1:7 :: x : 21
Product of means = Product of extremes
7*x = 1* 21
x = [tex]\frac{1*21}{7}[/tex]
x = 3
Length of the house in the scale drawing = 3 in
b) Height of the real house =y
1 : 7 :: 4 : y
Product of extremes = product of means
1 * y = 7*4
y = 7*4
y = 28
Height of real house = 28 feet

Find the missing angle or find X?
Answer:
x = 45
Step-by-step explanation:
Interior angles of a triangle sum up to 180
180 - 90 = 90
90 / 2 = 45
Answer:
X = 45
Step-by-step explanation:
Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,
90+45+45=180
In a lab experiment, 830 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 28 hours. How many bacteria would there be after 13 years, to the nearest whole number?
Answer:
1145
Step-by-step explanation:
830(2) 28/13
^ do that ok??????? plug it in!!!!!!!!
then do u know what u will get? u will get this !!!!!! y = 1145.09631989
round 2 da whole numba and den boom shakalaka B ) i got my question wrong so that i could put the right answer here. bye yall
The number of bacteria doubling every 28 hours will be 1145 after 13 hours.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
In the case of doubling the growth of bacteria, we can use the formula,
[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.
Therefore from the given information, the number of bacteria after 13 hours will be,
[tex]y_f = 830\times2^{\frac{13}{28}[/tex].
[tex]y_f = 830\times1.38[/tex].
[tex]y_f = 1144.86[/tex] or 1145 bacterias.

What is the best name for polynomial with 3 terms that has a degree
Answer:
Names of Degrees
Degree Name Example
1 Linear x+3
2 Quadratic x2−x+2
3 Cubic x3−x2+5
4 Quartic 6x4−x3+x−2
Answer:
Quartic Trinomial
Step-by-step explanation:
Monomial = one term
Binomial = two terms
Trinomial = three terms
Polynomial = four or more terms
As the other answer says, the order for degrees is:
Linear - to first degree
Quadratic - to second degree
Cubic - to third degree
Quartic - to fourth degree
Quintic - to fifth degree
Anything above fifth degree is just said "__th degree"
Example: x^7 + x^2 + 5 would be seventh degree trinomial
PLZ HELP PLZ (1a) Use long division to show the fraction and decimal in each pair are equivalent? 3/4 & 0.75. Hint: Divide 3/4.
Answer:
3 divided by 4 will equal 0.75 which is equivalent to 0.75. or you can do 6/8 which will also equal 0.75. and 6/8 is equivalent to 3/4. so therefore it's confirmed that 3/4 is equivalent to 0.75
