What is the value of x in the equation 2(5x + 4) = 17?
A 5/2
B 2/5
C 9/10
D 17/18
Answer:
[tex]\frac{9}{10}[/tex]
Step-by-step explanation:
[tex]2(5x+4)=17,\\10x+8=17,\\10x=9,\\x=\frac{9}{10}[/tex]
Analysis:
2(5x+4)=17
Distribute10x+8=17,
Subtract 8 from both sides to isolate x10x=9
Divide both sides by 10 to isolate xx=9/10 (ans)
Answer:
x = 9/10
Step-by-step explanation:
2(5x + 4) = 17
Distribute
10x+8 =17
Subtract 8 from each side
10x +8-8 = 17-8
10x = 9
Divide by 10
10x/10 = 9/10
x = 9/10

A soccer field is 110 yards long and 80 yards wide. What is the longest pass that one player can make to another player on a soccer field?
Answer and Step-by-step explanation:
To find the answer, we need to first think of what length in the rectangle can make the longest path, then use the Pythagorean Theorem.
The diagonal in a rectangle (going from one corner to another) is the longest distance.
If we were to split that rectangle by its diagonal, we would get a triangle. By the Pythagorean Theorem, we can find the length of that diagonal (the hypotenuse of the triangle).
[tex]A^2 + B^2 = C^2\\\\110^2+80^2 = C^2\\\\12100 + 6400 = C^2\\\\18500 = C^2\\\\10\sqrt{185} = C = 136.0147 yards[/tex] <- This is the answer (the decimal version or this ^ version).

In a (Gallup poll, 26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30, which is classified as obese. The 5000 people polled are a random sample of adults, aged 18 and older, from the United States population. Choose the correct interpretation for the 98% confidence interval for the proportion of the population who arc obese? A. The proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805. B. We are 98% confident the proportion of adults polled who are obese is between 0.2515 and 0.2805. C. In 98% of all samples, the proportion of adults polled who are obese will be between 0.2515 and 0.2805. D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Answer:
D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30
This means that [tex]\pi = 0.266, n = 5000[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 - 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2515[/tex]
The upper limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 + 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2805[/tex]
The correct interpreation is that we are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805, which means that the correct answer is given by option D.

Answer:
He traveled 520 miles
Step-by-step explanation:
8 x 65 = 520
Answer: 520 miles
Step-by-step explanation:
Data: Juan drove 8 hours
Drove at an average Speed of 65 mph
Miles driven=x
Only step: Multiply 65 by 8 which is 520
Explanation: Since Juan drove at an average speed of 65 miles per hour, that means he drove 65 mile for every hour he drove. So since he drove for 8 hours, you multiply 8 hours by 65 miles so that you get get the total amount of hours driven by him.
Don't forget to add "Miles" to the end of your answer because most math teachers tend to want that in an answer like this.

In the square below, the two semi-circles are congruent. Find the area of the
shaded region. If necessary, round your answer to two decimal places.
Answer:
3.44.
Step-by-step explanation:
We can see that in this square, the radii of the semicircles are 2. Using that, we can calculate that the area of each one is 6.58. Both combined is 12.56. Now, the original area of the circle was 16. 16 minus 12.56 is equal to 3.44, so the area of the shaded region is 3.44.

Question 1
Given the functions f(x) = 2x + 1 and g(x) = 5x +4, find m(x) = f(x) - g(x)?
A
m(x) = 3x + 3
B
m(x) = -3x + 5
С
m(x) = -3x - 3
D

Given :
⊕ f(x) = 2x + 1
⊕ g(x) = 5x + 4
⊕ m(x) = f(x) - g(x)
⇒ m(x) = (2x + 1) - (5x + 4)

Which set of ordered pairs does not represent a function? O {(4, -6), (-5,5),(-6,0), (7,0)} O {(0, -4), (9,6), (2,8), (8,8)} O {(8,-6), (9,-8), (2,4), (3, -6)} o {(-5,2), (3,-9),(-1,8), (-5,9)}
Function is a set of ordered pairs that do not have same domain or x-value. That means in a set of ordered pairs, the domain cannot have same value.
The only relation that isn't function here is the last choice because in a set of ordered pairs, there are two -5's which is repetitive. Other choices do not have same x-values in one set except for the last choice.

Answer:
382.50
Step-by-step explanation:
Area of the Shaded region = Area of the larger triangle - Area of the smaller triangle;
Let's find the area of the large triangle first;
A = 1/2(base) * (height)
A = 1/2(33) * (33)
A = 16.5 * 33
A = 544.5
Now let's find the area of the small triangle;
A = 1/2(base) * (height)
A = 1/2(18) * (18)
A = 9 * 18
A = 162
Area of the shaded region;
=> 544.5 - 162
=> 382.5 (if rounded to the nearest hundredths, 382.50)

g(- 4) = 3(- 4)³ + 5 = 3(- 64) + 5 = - 192 + 5 = - 187
Parallelogram W X Y Z is shown. Diagonals are drawn from point W to point Y and from point Z to point X and intersect at point C. The length of W C is (x + 4) feet and the length of C Y is (2 x minus 7) feet.
In parallelogram WXYZ, what is CY?
11 ft
15 ft
21 ft
23 ft
Answer:
b on edge 2021
Step-by-step explanation:
From the calculations, the length of CY in the parallelogram is 15 feet.
What is a diagonal?A diagonal is a line that runs from one end to another in a quadrilateral. We know that in such quadrilaterals as the parallelogram, the diagonals bisect each other.
Hence;
CY =WC
And
2x - 7 = x + 4
collecting like terms;
2x - x = 4 + 7
x = 11
Thus
CY = 2x - 7
= 2*11 - 7

Answer:
Oki Doki, read below this will be long.
Step-by-step explanation:
So, lets start with mr moy.
First off, we need to figure out the total hours that mr moy worked.
Throuhgout the 7 days of the week, he worked 5 days. These were his hours:
8, 8, 8, 8, 9
Adding these together, you get a total of 41 hours.
Next we have total wage.
To find this, multiply the total hours by the hourly income. We know the hourly income is 12.5, and the total hours is 41:
12.5*41=512.5
So 512.5 is the total wage.
Lets do this for the next four people, I am just going to speed it up a bit:
Ms wong - hours - 8+8+7+9+9 =41. Hourly income - 9.5. Total income: 9.5*41:
389.5 is total income
41 is total hours
Maria - hours - 5+5+6+8+9=33. Hourly income - 7.5. Total income: 7.5*33:
247.5 total income
33 total hours
Tom - 4+4+4+4+4+8+8=36. Hourly income - 7.5. Total income: 7.5*36:
270 total income
36 total hours
Jacob - 5+5+5+7+7 =29. Hourly income - 7.5. Total income: 7.5*29:
217.5 total income
29 total hours
OK, now for the total sums:
Total hourly wages - 7.5+7.5+7.5+12.5+9.5=44.5
Total of the total hours - 41+41+33+36+29=180 hours
Total of total wages - 217.5+512.5+389.5+270+247.5=1637
Ok, thats it for the first page.
On the next pages, I was slightly confused. But Ill try my best.
A - for each employ, calculate total hours and wages. We already did this before.
B - What is the total amount that is paid out in wages in a week. We already did this before(1637)
C - which day is the busiest day of the week - Saturday. The slowest? Monday
So we know the slowest day has to be monday, since the total employment hours is 8+8+4=20. WHich is lower than the rest.
We also know the busiest day has to be saturday, since the total employment hours is 9+9+8+5=31. Which is higher than the rest.
Now to the the third page.
What is the average employe wage?
Lets add up all the wages, and divide by the amount of wages:
7.5+7.5+7.5+9.5+12.5=44.5
44.5/5
=
8.9
This is the average wage.

Find the distance between (1, -5) and (-6, 2).
**If necessary, round to the nearest tenth**
98 units
34 units
9.9 units
5.8 units
Answer:
d = 9.9 units
Step-by-step explanation:
Picture a right triangle with one acute vertex at (1, -5) and the other at (-6, 2). Going from one to the other, we see a change in x (run) of 7 and a change in y of 7. Applying the Pythagorean Theorem, we find the distance between the two points as follows:
d = √(7² + 7²) = 7√2, or approximately 9.9 units.
