Determine if the given value of the variable is the solution of the equation . write yes or no .
please i need help i will mark u brill
Answers
Answer:
no, b does not equal 5 in that equation
Step-by-step explanation:
if you solve for x, this is how it would look:
65/b + 8 x 4 = 20
65/b + 32 = 20
65/b = 20 - 32
65/b = -12
65 = -12b
-12b = 65
b = -65/12 (or -5 5/12)

Elijah bought a new car for $25,000. He paid
$5,000 up front and then $600 per month. How
many months will it take Elijah to pay off the car?
Answers
Answer: 6 days too be exact
Step-by-step explanation:
Answer:
33.333 months
Step-by-step explanation:
25,000-5,000=20,000
20,000/600=33.333
If he payed $5,000 upfront, the he only has $20,000 remaining to pay. If he is paying $600 a month then you divide the $20,000 by the $600 to 33.333 months. Hope this helps
Solve 3y^3 + 12y^2 + 12y =0
Please
Answers
Answer:
y = 0, -2
Step-by-step explanation:
Factor out the common term 3y.
[tex]3y( {y}^{2} + 4y + 4) = 0[/tex]
Rewrite y² + 4y + 4 in the form of a² + 2ab + b², where a = y and b = 2.
[tex]3y( {y}^{2} + 2(y)(2) + {2}^{2} ) = 0[/tex]
Use square sum: (a + b)² = a² + 2ab + b².
[tex]3y(y + 2) ^{2} = 0[/tex]
solve for y.
y = 0, -2.
therefor, the answer for this equation is 0, - 2.

Child Health and Development Studies (CHDS) has been collecting data about expectant mothers in Oakland, CA since 1959. One of the measurements taken by CHDS is the weight increase (in pounds) for expectant mothers in the second trimester. In a fictitious study, suppose that CHDS finds the average weight increase in the second trimester is 14 pounds. Suppose also that, in 2015, a random sample of 45 expectant mothers have mean weight increase of 16.3 pounds in the second trimester, with a standard deviation of 5.9 pounds. A hypothesis test is done to see if there is evidence that weight increase in the second trimester is greater than 14 pounds. Find the p -value for the hypothesis test. The p -value should be rounded to 4 decimal places.
Answers
Answer:
0.9955
Step-by-step explanation:
Given :
Mean weight increase , μ = 14
Sample mean weight increase , xbar = 16.3
Standard deviation, s = 5.9
Sample size, n = 45
Hypothesis :
H0 : μ = 14
H1 : μ > 14
The test statistic : (xbar - μ) ÷ (s/sqrt(n))
Test statistic = (16.3 - 14) ÷ (5.9/sqrt(45))
Test statistic = 2.3 / 0.8795200
Test statistic = 2.615
The Pvalue :
P(Z < 2.615) = 0.99554
Hence, pvalue = 0.9955 (4 decimal places).

A baker has small and large bags of sugar for making cakes. The large bag contains 30 cups cups of sugar and is 2.5 times larger than the small bag. The small bag contains enough sugar to make 9 cakes and have 0.75 cups of sugar remaining. How many cakes can be made with a large bag of sugar?
Answers
Answer:
Step-by-step explanation:
The first thing we need to focus on is the fact the large bag (30 cups) is 2.5 larger than the small bag. So, the first we need to do is divided 30 by 2.5, which is 12. (300/25 = 30/2.5 = 12, in case you're confused.) So the small bag has 12 cups of sugar.
What that down, we need to focus how many cakes the small bag can make, which was 9. 3/4 of a cup is left over. We can create an equation from that info, that being 9x + 0.75 = 12. Now let's solve for x.
9x + 0.75 = 12
First, subtract 0.75 from both sides. With that, we can solve for x directly.
9x = 12 - 0.75
9x = 11.25
Now, divide both sides by 9.
x = 11.25/9
x = 1.25
With that, we now know that each cake needs 1.25 cups of sugar.
With that, the last thing we need to is divide 30 by 1.25. Again, I can use powers of ten, to quickly divide 3000 by 125 (10²) to get 24 cakes.
With that done, we have our answer. 24 cakes can be made with a large bag of sugar.
I hope this helps! (⌒ω⌒)

Answer:
(c) 18.55
Step-by-step explanation:
The law of sines tells you ...
y/sin(106°) = 15/sin(51°)
y = 15×sin(106°)/sin(51°)
y ≈ 18.55
_____
The same kind of proportion can find x:
x = 15×sin(23°)/sin(51°)
x ≈ 7.54
Please note that the question posted here asks for the value of y. The value of x and the complete triangle solution are provided as a courtesy to those who may be asked for other values in this triangle.

Which of the following is a tangent line to circle O?
a. line EF
b. segment OD
c. segment BC
d. line AG
Answers
Answer:
d.
Step-by-step explanation:
line AG is the answer because a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior.
Answer:
d. line AG
Step-by-step explanation:
A tangent is a line that just 'touches' the curve of a circle, and doesn't intersect it.
We can see that since AG touches the circle, and since the other lines all intersect the circle, the tangent here is AG

C. ... 3 1/4 cups
Step-by-step explanation:
The problem statement tells you that the other measures are combined. That means you're looking for an expression like ...
3/8 × ((3 2/3) +(2 1/4) +(2 3/4))
This eliminates choices B and D.
If you look at the numbers in parentheses, you see that the 1/4 and 3/4 will have a sum of 1, so the only fraction in the sum will be 2/3. This eliminates choice A.
The only viable answer choice is C.

If you like, you can check to see that answer C is correct.
(3/8)(8 2/3) = (3/8)(26/3) = 26/8 = 3 2/8 = 3 1/4
