In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7
Answer:
34°
Step-by-step explanation:
1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.
2. (Solving for ∠1)
[tex]146 + x = 180[/tex] [tex]146 + x - 146 = 180 - 146[/tex] [tex]x = 34[/tex]3. Now, since we know ∠1 = ∠7, ∠7 = 34°.

Solve and check the equation.[tex]\frac{x}{10}=\frac{5x}{7} -43[/tex]
Answer:
x = 70
Step-by-step explanation:
Step 1: Simplify both sides of the equations.
[tex]\frac{x}{10} = \frac{5x}{7}-43[/tex] [tex]\frac{1}{10}x=\frac{5}{7}x-43[/tex]Step 2: Subtract 5/7x from both sides.
[tex]\frac{1}{10}x- \frac{5}{7}x = \frac{5}{7}x - 43 - \frac{5}{7}x[/tex] [tex]\frac{-43}{70}x = -43[/tex]Step 3: Multiply both sides by 70/(-43).
[tex]\frac{-43}{70}x * \frac{70}{-43} = -43*\frac{70}{-43}[/tex] [tex]x = 70[/tex]Step 4: Check if solution is correct.
[tex]\frac{(70)}{10}=\frac{5(70)}{7} -43[/tex] [tex]7 = \frac{350}{7} - 43[/tex] [tex]7 = 50 - 43[/tex] [tex]7 = 7[/tex]Therefore, x = 70.
h(x)=(x+1)^2 find functions f(x) and g(x) so that h(x)=f(g)(x))
9514 1404 393
Answer:
f(x) = x²g(x) = x+1Step-by-step explanation:
There are numerous possible solutions. Perhaps the simplest is to look at what happens to x in the expression for h(x).
x has 1 addedthe sum is squaredThis suggests that f(x) will square the result of g(x), and that g(x) will add 1 to x:
g(x) = x +1
f(x) = x²
__
Check
h(x) = f(g(x)) = f(x+1) = (x+1)² . . . . as required
_____
Additional comment
For some (almost) arbitrary function g(x), the function f(x) can include its inverse (to get the value of x+1), then perform the square. If g(x) involves powers of x, then f(x) only needs to do enough of an inverse to find (x+1)². Here's a relatively simple example.
g(x) = 2x+3
f(x) = (x -1)²/4
Then h(x) = f(g(x)) = f(2x +3) = ((2x +3) -1)²/4 = (2(x+1))²/4 = (x+1)²
Kevin's earnings vary directly with the number of hours he works. Suppose that he worked 7 hours yesterday and earned $112. How much will he earn today if he works 10 hours?
Answer:
$160 in 10 hours
Step-by-step explanation:
We know that Kevin earns $112 for working 7 hours. To find the answer for 10 hours, we need to find the unit rate.
Divide 112÷7= $16 for every 1 hour he works.
Now, we can use the unit rate to find the amount earned for 10 hours.
16×10= $160

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 45 pounds each, and the small boxes weigh 20 pounds each. There are 135 boxes in all. If the truck is carrying a total of 4450 pounds in boxes, how many of each type of box is it carrying?
Answer:
45 - big boxes, 200 - small boxes
Step-by-step explanation:
45 x 10 = 450
200 x 20 = 4000
Total = 4,450

Use the graph to determine the y intercept
Answers:
y intercept: 9zeros: -3, -1, 1, 3===============================================
Explanation:
The y intercept is where the curve crosses the y axis. The curve appears to do so just below y = 10, so y = 9 seems like a good estimate. I'm basing this off of the answer choices given. The y intercept always occurs when x = 0.
The zeros, aka roots or x intercepts, are where the curve crosses or touches the x axis. This occurs in four locations: x = -3, x = -1, x = 1 and x = 3. The x intercepts always occur when y = 0.

Step-by-step explanation:
The number of employees before the layoff = 2000
What is percentage?"It is a number can be expressed as a fraction of 100."
For given question,
Let 'n' be the the number of employees before layoff.
A company laid off 80% of its work force.
The number of employees after the layoff is 400.
The number of employees after the layoff would be,
⇒ n - (80 percent of n) = 400
[tex]\Rightarrow n-(n\times \frac{80}{100} )=400\\\\\Rightarrow n[1-0.8]=400\\\\\Rightarrow n\times 0.2=400\\\\\Rightarrow n=2000[/tex]
Therefore, the number of employees before the layoff = 2000

the length of 6 identical iron rods is 48 unit what will be the total length of 9 such rods
The total length of 9 rods will be 72 units.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The length of 6 identical iron rods is 48 unit.
Now,
Since, the length of 6 identical iron rods is 48 unit.
Hence, the length of 9 identical iron rods = 9 × 48 / 6
= 9 × 8
= 72 units
Thus, The total length of 9 rods will be 72 units.

Suggestions:
2x - 6y = 6
6x - 4y = 2
Answer:
x = - 3/7
y = - 8/7
Step-by-step explanation:
(2x - 6y = 6)/2 =
x - 3y = 3
x = 3y + 3
Substitution:
6 (3y +3) - 4y = 2
18y + 18 - 4y = 2
14y = -18+2
y = -16/14
y = - 8/7
Substitution:
x = 3(-8/7)+3
x = -24/7 + 3
x = -3/7

Answer:
(x, y) = (-3/7, -1 1/7)
Step-by-step explanation:
We can divide each equation by 2 and subtract the constant to put them in general form.
x -3y -3 = 0
3x -2y -1 = 0
This form facilitates use of the "cross multiplication method" of solution. That method tells us ...
1/d1 = x/d2 = y/d3
where the differences d1, d2, d3 are the differences of cross-products:
d1 = 1(-2) -(3(-3)) = 7
d2 = -3(-1) -(-2(-3)) = -3
d3 = -3(3) -(-1(1)) = -8
Then the solutions are ...
x = d2/d1 = -3/7
y = d3/d1 = -8/7
(x, y) = (-3/7, -8/7)

When the general form equations ax+by+c=0 and dx+ey+g=0 have their coefficients written in two rows: (note the repeated first coefficient)
a, b, c, ad, e, g, dThe pattern in the cross-differences is relatively easy to see:
d1 = ae -dbd2 = bg -ecd3 = cd -gaThe expressions for the solution values, (x, y) = (d2/d1, d3/d1), are substantially identical to those of Cramer's method.
According to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on a bench in a mall and observe people's habits as
they sneeze. Complete parts (a) through (c)
(a) What is the probability that among 12 randomly observed individuals, exactly 7 do not cover their mouth when sneezing?
Using the binomial distribution, the probability is
(Round to four decimal places as needed.)
(b) What is the probability that among 12 randomly observed individuals, fewer than 5 do not cover their mouth when sneezing?
Using the binomial distribution, the probability is 1
(Round to four decimal places as needed.)
(c) Would you be surprised if, after observing 12 individuals, fewer than half covered their mouth when sneezing? Why?
No, I would not be surprising, because using the binomial distribution, the probability is . which is v0.05
(Round to four decimal places as needed.)
Using the binomial distribution, it is found that:
a) There is a 0.0162 = 1.62% probability that among 12 randomly observed individuals, exactly 7 do not cover their mouth when sneezing.
b) There is a 0.5958 = 59.58% probability that among 12 randomly observed individuals, fewer than 5 do not cover their mouth when sneezing.
c) The probability is higher than 5%, so it would not be unusual.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, with p probability.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem:
Sample of 12, thus [tex]n = 12[/tex]0.267 probability that a person covers their mouth, thus [tex]p = 0.27[/tex].Item a:
This probability is P(X = 7), so:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 7) = C_{12,7}.(0.267)^{7}.(0.733)^{5} = 0.0162[/tex]
There is a 0.0162 = 1.62% probability that among 12 randomly observed individuals, exactly 7 do not cover their mouth when sneezing.
Item b:
The probability is P(X < 4), which is:
[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{12,0}.(0.267)^{0}.(0.733)^{12} = 0.0241[/tex]
[tex]P(X = 1) = C_{12,1}.(0.267)^{1}.(0.733)^{11} = 0.1052[/tex]
[tex]P(X = 2) = C_{12,2}.(0.267)^{2}.(0.733)^{10} = 0.2107[/tex]
[tex]P(X = 3) = C_{12,3}.(0.267)^{3}.(0.733)^{9} = 0.2558[/tex]
Then
[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0241 + 0.1052 + 0.2107 + 0.2558 = 0.5958[/tex]
There is a 0.5958 = 59.58% probability that among 12 randomly observed individuals, fewer than 5 do not cover their mouth when sneezing.
Item c:
This probability is:
[tex]P(X < 6) = P(X < 4) + P(X = 5) = 0.5958 + P(X = 5)[/tex]
Negative probabilities do no exist, thus, this probability is guaranteed to be above 0.05, which means that it would not be unusual if fewer than half covered their mouth when sneezing.

If (x-3) ²=16, find the positive value of x.
7
Step-by-step explanation:
(x - 3)² = 16
x² - 6x + 9 = 16
x² - 6x + 9 - 16 = 0
x² - 6x - 7 = 0
(x - 7)(x + 1)
x = 7 \/ x = -1
so positive value of x = 7
