Find the specified value.
(2x +5)
a. Using the figure to the right, find the value of x.
b. Using the figure to the right find the value of y.
Answer:
a. The value of x is [tex]38^{o}[/tex].
b. The value of y is [tex]25^{o}[/tex].
Step-by-step explanation:
a. Applying the vertically opposite principle,
(2x + 5) = (3x - 33)
2x + 5 = 3x - 33
33 + 5 = 3x - 2x
38 = x
⇒ x = [tex]38^{o}[/tex]
b. Sum of angles on a straight line = [tex]180^{o}[/tex]
So that,
(4y - 1) + (3x - 33) = [tex]180^{o}[/tex]
But,
( 3x - 33) = (3x38 - 33)
= 114 - 33
= [tex]81^{o}[/tex]
(4y - 1) + [tex]81^{o}[/tex] = [tex]180^{o}[/tex]
4y - 1 = [tex]180^{o}[/tex] - [tex]81^{o}[/tex]
= [tex]99^{o}[/tex]
4y = [tex]99^{o}[/tex] + 1
= [tex]100^{o}[/tex]
y = [tex]\frac{100}{4}[/tex]
= [tex]25^{o}[/tex]
y = [tex]25^{o}[/tex]
The value of x is [tex]38^{o}[/tex], and y is [tex]25^{o}[/tex].

Solve by elimination:
2x + y = 20
6x - 5y = 12
Group of answer choices
(7 , 6)
(6 , 7)
(-7 , -6)
(4 , 10)
Answer:
its (7,6)
Step-by-step explanation:
2x + y = 20
2(7) + 6 = 20
14 + 6 = 20
20 = 20
6x - 5y = 12
6(7) - 5(6) = 12
42 - 30 = 12
12 = 12

Quadrilateral A'B'C'D' is the image of quadrilateral ABCD under a dilation with a scale factor of 4. What is the length of segment CD'?
Answer:
C'D' = 8
Step-by-step explanation:
A'B'C'D' is the figure gotten by multiplying each segment of Quadrilateral ABCD by the scale factor of 4.
To get the length segment of C'D', multiply the length of CD by 4.
CD = 2 units
Therefore, C'D' = 4*2
C'D' = 8
Answer: it was 12 :(
Step-by-step explanation:
I got it wrong on khan academy but then I checked the explanation and it wasn’t 8 but 12.
Ariana invested $400 in an account paying an interest rate of 3.8% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 11 years?
Answer:
After 11years there'll be$602.880
Step-by-step explanation:
Amount after 11years
=$400(1+3.8/100)¹¹
=$602.880
The after 11 years the amount will be $602.880
We have given that,
Ariana invested $400 in an account paying an interest rate of 3.8% compounded monthly.
What is the formula for the future value on simple interest?[tex]A=p(1+r)^n[/tex]
Amount after 11 years,
[tex]P=$400r=3.8[/tex]
[tex]=\frac{3.8}{100} =0.38[/tex]
[tex]=$400(1+3.8/100)^{11}[/tex]
[tex]=$602.880[/tex]
Therefore the after 11 years the amount will be $602.880.

Find the probability of rolling divisors of 24
Answer:
5/6 is the probability
Step-by-step explanation:
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so

Formula = 450 meters in 25 seconds
Average speed = 450m/25s
The unit rate is equivalent to 18m/s.
[Basically, just divide 450 meters by 25 seconds to get 18 meters per second. 18 is the unit rate :) ]

On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictable time by a slightly louder sound. The time it takes for the participant to react to the louder sound is recorded. The following list contains the reaction times (in milliseconds) for 8 trials of this experiment:
486, 358, 395, 759,496, 692, 353, 306 0
(a) What is the mean of this data set? If your answer is not an integer, round your answer to one decimal place.
(b) What is the median of this data set? If your answer is not an integer, round your answer to one decimal place.
(c) How many modes does the data set have, and what are their values?
Answer:
480.6 ; 440.5, 8 mode values
Step-by-step explanation:
Given that :
Given the data :
486, 358, 395, 759,496, 692, 353, 306
Rearranged data: 306, 353, 358, 395, 486, 496, 692, 759
The mean:
Σx/ n
n = sample size = 8
Σx = sum of all data values = 3845
Mean = 3845 / 8
Mean = 480.6
The median :
0.5(n + 1)th term
0.5(8 + 1) th term
0.5(9)th term
= 4.5term
(4th + 5th term) / 2
(395 + 486) / 2
= 440.5
The mode = most frequently occurring data value ; since all the data values have a frequency of 1, then the number of modes = 8.
