Lines R and S are parallel. Find the value of x, then find the measure of 21 and 22.
m21=(74 - x)º
m22 =(85 – 2x)
Answers
Answer:
a) The value of x = 11°
b) m21 = 63°
m22= 63°
Step-by-step explanation:
Step(i):-
Given that the lines R and S are parallel
Given that M21 = (74-x)°
M22 = (85-2x)°
Equating angles
(74-x)° = (85-2x)°
74 - 85 = x -2x
-11 = -x
x = 11°
Step(ii):-
Put x = 11°
⇒ m21 = ( 74 -11) ° = 63°
⇒ m22 = (85-2(11))° = (85-22)° = 63°
Final answer:-
a) The value of x = 11°
b) m21 = 63°
m22= 63°

35.84
Step-by-step explanation:
32x1.12=35.84
Answer:
$35.84
Step-by-step explanation:
Hi! Ace here.
The easiest way to do this is to use benchmark fractions.
10% of 32 = 3.2
1% of 32 = .32
1% of 32 = .32
Add up all the numbers:
3.2 + .32 + .32 = 3.2 + 64 = 3.84
Since it's a mark up, we do:
32 + 3.84 = $35.84
You can also use percent proportions which would look like this. I'm not going to explain it that much because I think that's what the other person did.
[tex]\frac{x}{112} =\frac{32}{100}[/tex]
[tex]x=\frac{112*32}{100} \\\\x=\frac{3584}{100} \\\\x=35.84[/tex]

By knowing all sides of triangle and applying the formula of the law of the cosines we conclude that the missing angle X is approximately 117.9°.
How to find the missing angle
In this question we have a triangle with three known side lengths but all missing angles, we can determine the missing angle by using the law of cosines. If we know that x = 90 ft, y = 55 ft and and z = 50 ft, then the missing angle X is:
90² = 55² + 50² - 2 · 55 · 50 · cos X (1)

Help please! Could you explain it too?
Answers
Answer:
a) not proportional
b) proportional; k = [tex]-\frac{3}{5}[/tex]
Step-by-step explanation:
a) for any proportional equation, the line must pass through the origin. The equation in a) is y = 4x + 1, and the '+1' is the y-intercept. This means that the line does not pass through the origin, so x and y cannot increase by the same amount (i.e. they are not proportional).
Another way to determine this is is to use the y = kx base. If you have an equation that fits that it's likely proportional.
Here, if the equation was only y = 4x then it'd be proportional because u can see that k = 4. This is not the equation though, and the 4x + 1 doesn't fit to the y = kx formula so it can't be proportional.
b) straight away you can see that there's no 'c' term (y = mx + c) which means the y-intercept is 0, so the line passes through the origin. While this does not immediately mean the line is proportional, you can make sure that it is by checking it fits with the y = kx equation.
y = -(3/5)x fits with y = kx, with k being -3/5

Answers
Answer:
35
Step-by-step explanation:
The sample size should be as large as, 55 is the largest value option fifth 55 have the least variability in the sampling distribution of the sample mean.
What are population and sample?It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.
We know in sampling distribution:
variance ∝ 1/√n
Because,
[tex]\rm \sigma_\bar{x} \ =\ \sigma_{\sqrt{n}}[/tex]
From the above relation, as the sample size is large, the variability is less.
For least variability,
The sample size must be large.
Thus, the sample size should be as large as, 55 is the largest value option fifth 55 have the least variability in the sampling distribution of the sample mean.

What is the probability of spinning a number greater than 5 on a spinner numbered 1-8 and tossing a tail on a coin
Answers
Answer:
3/16
Step-by-step explanation:
P(6,7,8 and 'T') = 3/8 x 1/2 = 3/16
Answer:
12/64
Step-by-step explanation:
We have numbers 1-8 = /8
We have the numbers 6, 7, 8 on the spinner = 3/8
We have the event it doesn't get over 8 too = 8/8-3/8 = 5/8
To use if the question has two events for spinner.
We toss a coin = H or T = 1/2
We convert a 3/8 and 1/2 to same HCF = 4/8 = ( 2x 4 = 8)
3/8 x 4/8 = 12/64
Pamela is 5 years younger than Jiri. The sum of their ages is 81. What is Jiri's age?
Answers
Pamela is 5 years younger mean
Mean Jiri is old 5 years, take number of Jiri age minus Pamela age.
-> J-5=P
The sum mean plus
P+J=81
Use substitution for the equation 1 to find the answer.
(J-5) +J=81
2J-5=81
2J=86
J=43
Answer: Jiri is 43 years old
Step-by-step explanation:
Let x be the age of Pamela, and (x+5) be the age of Jri
Expression
x+(x+5)=81
Expand paranthesis
x+x+5=81
Combine like terms
2x+5=81
Subtract 5 on both sides
2x+5-5=81-5
2x=76
Divide 2 on both sides
2x/2=76/2
x=38
Since we've set Jiri's age as (x+5), we need to substitute the value of x
x+5=38+5=43

Answer:

Step-by-step explanation:
Given that,
The length of the rectangle, [tex]l=(3+\sqrt7)\ m[/tex]
The width of the rectangle, [tex]b=(1+2\sqrt{7} )\ m[/tex]
We need to find the area of the rectangle. We know that the area of the rectangle is given by :
[tex]A=l\times b[/tex]
Put all the values in the above formula.
[tex]A=(3+\sqrt7)\times (1+2\sqrt7)\\\\=3+3\times 2\sqrt7 +\sqrt7+2(\sqrt7)^2\\\\=3+6\sqrt7+\sqrt7+14\\\\=(17+7\sqrt7)\ m^2[/tex]
So, the area of the rectangle is [tex](17+7\sqrt7)\ m^2[/tex].

Answer:
The solution to the system of equation is (0, 2). The equation has only one solution.
Step-by-step explanation:
Given the system of equations
y= x + 2 .... 1
2y = x + 4 ... 2
Substitute equation 1 into 2;
From 2; 2y = x+4
2(x+2) = x+4
2x+4 = x+4
2x - x = 4-4
x = 0
Substitute x = 0 into 1;
From 1; y = x+2
y = 0+2
y = 2
Hence the solution to the system of equation is (0, 2). The equation has only one solution.
