Answer:
5(5x-t)
=13×5
25x - 5t
=65
25x -5t + 4x +5t
=65 + 22
29x
= 87
x
= 87÷29
x =3
substituting x=3 in 5x-t=13
15- t
=13
15 - 13
= t
t = 2

find area of shaded regions
Answer:
140.8584073
Step-by-step explanation:
Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.

Answer:
Option D
Step-by-step explanation:
Given the following question:
Airline makes $98,410
Truck driver makes $38,200
Annually means in a year so the airline makes $98,410 and the truck driver makes $38,200 in a year.
Now in order to find the amount the two make in 20 years we have to multiply:
[tex]98410\times20=1968200[/tex]
[tex]38200\times20=764000[/tex]
Now since the question asks "how much MORE" does the airline make we have to subtract:
[tex]1968200-764000=1204200[/tex]
[tex]=1204200[/tex]
The airline makes "$1,204,200 more dollars" than the truck driver, or option D.
Hope this helps.
Answer:
The answer is either D or B
Step-by-step explanation:
98,410 x 20 is 1,968,200 so
it might be closer to D or B instead.

In the diagram below, FG is parallel to CD. If the length of C D is the same as the
length of FE, CE = 17, and FG = 6, find the length of FE. Figures are not
necessarily drawn to scale. State your answer in simplest radical
Answer: sqrt(102)
Step-by-step explanation:
We know that triangles GFE and DCE are similar by AA.
If we let CD=FE=x, then we can set up a proportion. Namely,
CE/FE = CD/FG
17/x = x/6
x^2 = 102 -> x=sqrt(102)
A bacteria population decreases by a factor of 1/2 every 4 hours. Explain why we could also say that the population decays by a factor of (1/2 )^1/4 every hour.
Answer:
(1/2)^(t/4) = ((1/2)^(1/4))^t
Step-by-step explanation:
If time t is given in hours, then the number of 4-hour time periods is t/4. If the half-life is 4 hours, the population multiplier is ...
(1/2)^(t/4)
Using the rules of exponents, that can be rearranged to ...
(1/2)^((1/4)·t) = ((1/2)^(1/4))^t
That is, the multiplier every hour is ...
(1/2)^(1/4)
_____
The relevant rule of exponents is ...
(a^b)^c = a^(bc)

A bag contains 16 blue marbles, 12 red marbles, and 12 green marbles. If Malik randomly draws a marble from the bag (and puts it back) 25 times, how many times should he expect to pull a blue marble? Enter your answer as a number, like this: 42
The expected number of times he picks a blue marble is the mean of the blue marbles
Malik should expect to pick a blue marble 10 times when he picks 25 marbles
How to determine the expected timesThe given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So, we have:
Total = 40
When he picks 25 marbles, the expected number of blue marble is:
Expected = Blue/Total * 25
So, we have:
Expected = 16/40 * 25
Evaluate the product
Expected = 10
Hence, he should expect to pick a blue marble 10 times when he picks 25 marbles

What is the solution to this equation?
−4(2m − 7) = 3(52 − 4m)
Answer:
m = 32
Step-by-step explanation:
-4(2m-7) = 3(52 - 4m)
-8m + 28 = 156 - 12m
-8m + 12m = 156 - 28
4m = 128
m = 32 Ans...
The required solution is m = 32 to the given equation −4(2m − 7) = 3(52 − 4m).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have been given an equation as
⇒ -4(2m-7) = 3(52 - 4m)
Apply the distributive of multiplication,
⇒ -8m + 28 = 156 - 12m
Rearrange the terms of m in the above equation,
⇒ -8m + 12m = 156 - 28
Apply the subtraction operation,
⇒ 4m = 128
Divided by 4 both sides of the equation, we get
⇒ m = 32
Therefore, the solution is m = 32 to the given equation −4(2m − 7) = 3(52 − 4m).

Answer:
a = 7
Step-by-step explanation:
Using the Cosine rule in the triangle
a² = b² + c² - (2bc cosA )
= 2² + (5[tex]\sqrt{3}[/tex] )² - (2 × 2 × 5[tex]\sqrt{3}[/tex] × cos30° )
= 4 + 75 - (20[tex]\sqrt{3}[/tex] × [tex]\frac{\sqrt{3} }{2}[/tex] ) ← exact value of cos30°
= 79 - ( 10 × 3)
= 79 - 30
= 49 ( take square root of both sides )
a = [tex]\sqrt{49}[/tex] = 7
Answer:
a = 7
Step-by-step explanation:
a² = b² + c² - 2bc × cos α
a² = 2² + ( 5√3 )² - 2 × 2 × 5√3 × [tex]\frac{\sqrt{3} }{2}[/tex]
a² = 49

Find the Perimeter of the figure below, composed of a rectangle and a semicircle.
Round to the nearest tenths place.
Answer:
53.7
Step-by-step explanation:
Rectangle: lenth = 14, width = 2 * 5 = 10
perimeter of reactangle (3 sides) = 14 + 10 + 14 = 38
perimeter of semicircle = π * 5 = 3.14 * 5 = 15.7
Total perimeter = 38 + 15.7 = 53.7
Answer:
Step-by-step explanation:
Rectangle:
Length = 14 units
Width = diameter of the semicircle = 2*5 = 10 units
Circumference of circle = πr = 3.14 * 5 = 15.7 units
Perimeter of the figure = 14 + 10 + 14 + 15.7 = 53.7 units
There is a bag filled with 2 blue, 4 red and 3 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 different colours?
Answer:
.753
Step-by-step explanation:
Let Ps = probability both marbles are the same color.
Let Pd = probability both marbles are a different color.
Pd = 1 -Ps
Let Pb = probability both marbles are blue
Let Pr = probability both marbles are red.
Let Pg = probability both marbles are green
Pb= 2/9 * 1/9 = 2/81
Pr= 4/9 * 3/9 = 12/81
Pg=.3/9 * 2/9= 6/81
Ps = Pb + Pr +Pg= 20/81
Pd =1-Ps= 61/81 = .753
