Answer:
1.7 candy bars
Step-by-step explanation:
create a proportion: bars/grams = bars/grams
'b' = # bars
24/3.5 = b/0.25
3.5b = 6
b = 1.7
The dimensions of a rectangle are 2x – 5 and 3x + 3. Which expression
represents the area of the rectangle in simplest form?
Answer: 2x - 5
Step-by-step explanation: 2x - 5 does not have anything in common, so therefore it can not be simplified. Then 3x - 3 can be divided by 3 because they have that in common. It can’t be 3x - 3 because it still contains one step left to be in its most simplified form.

Find the value of x, y, and z
Answer:
x= 121 degrees
y=40 degrees
z=199 degrees
Step-by-step explanation:
121 (B) matches with x
40 (A) matches with y
C (unknown) matches with z, and 360 degrees minus 161 (121+40) is 199 degrees
A random sample of size 16 is to be taken from a normal population having mean of 100 andvariance 4. What is the 90th percentile of the distribution of x?
The 90th percentile of the distribution of x is 100.64.
Given that,
A random sample of size 16 is to be taken from a normal population having mean of 100 and variance 4calculation:Here we have
[tex]n=16,\mu=100,\sigma^{2}=4[/tex]
Now we requried z-score that has 0.90 area to its left. z-score 1.28 has 0.90 area to its left.
So required 90th percentile is
[tex]z=\frac{\bar{x}-\mu}{\sigma/\sqrt{n}}\\\\1.28=\frac{\bar{x}-100}{2/\sqrt{16}}\\\\\bar{x}=100.64[/tex]

Given:
[tex]\to n=16\\\\\to \mu=100\\\\ \to \sigma^{2}=4[/tex]
To find:
distribution [tex]\bar{x}=?[/tex]
Solution:
We require a z-score with such a 0.90 area to its left in this case. The area to the left of the z-score 1.28 is 0.90. As a consequence, the required 90th percentile is
Using formula:
[tex]\to z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}\\\\[/tex]
[tex]\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{16}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{4^2}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{4}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{1}{2}}\\\\\to 1.28=\frac{\bar{x}-100}{0.5}\\\\\to 0.64 =\bar{x}-100\\\\\to \bar{x}=100+0.64\\\\\to \bar{x}=100.64\\\\[/tex]
Therefore, the answer is "100.64".

Solve: 2(4z - 2) = 44
Answer:
z = 6
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Distribute: 8x - 4 = 44
Add 4 on both sides, to get rid of the 4 on the left side: 8x = 48
Divide by 8 on both sides, to get the final value of x -->
Answer: x = 6

A jet flies due North far a distance of 50 cm and then on a bearing of N TOE for a furter
km. Find the distance and bearing of the jet from its starting point
Answer:
90 km, N 46° E
Step-by-step explanation:
A jet flies due North for a distance of 50 km and then on a bearing of N 70° E for a further 60 km. Find the distance and bearing of the jet from its starting point.
Look at the diagram I drew of this scenario. You can see the jet flies North for 50 km, and then turns at a 70° angle to fly another 60 km. We want to find the distance from the starting point, SP, to angle C (labeled).
This will be the jet's distance from its starting point.
In order to find the bearing of the jet from its starting point, we will need to find the angle formed between distances b and c, labeled angle A.
The Law of Cosines will allow us to use two known sides and one known angle to solve for the sides opposite of the known angle.
In this case, the known angle is 110° (angle B) so we will use the Law of Cosines respective to B.
b² = a² + c² - 2ac cosBSubstitute the known values into the equation and solve for b, the distance from the starting point (A) to the endpoint (C).
b² = (60)² + (50)² - 2(60)(50) cos(110°)b² = 6100 -(-2052.12086) b² = 8152.12086b = 90.28909602b ≈ 90 kmThe distance of the jet from its starting point is 90 km. Now we can use this b value in order to calculate angle A, the bearing of the jet.
The Law of Cosines with respect to A:
a² = b² + c² - 2bc cosASubstitute the known values into the equation and solve for A, the bearing from the starting point (clockwise of North).
(60)² = (90.28909602)² + (50)² - 2(90.28909602)(50) cosA 3600 = 8152.12086 - 6528.909602 cosA-4552.12086 = -6528.909602 cosA0.6972252853 = cosA A = cos⁻¹(0.6972252853) A = 45.79519A ≈ 46°The bearing of the jet from its starting point is N 46° E. This means that it is facing northeast at an angle of 46° clockwise from the North.

Henry will spend at most $30 on gifts. So far, he has spent $21. What are the possible additional amounts he will spend? Use c for the additional amount in dollers henry will spend
Answer:
He will spend less than or equal to $9
Step-by-step explanation:
21 + c </= 30
c</= 9
Solve for xxx. -30=5(x+1)
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]
[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.

Find the original price given the total amount and the tip rate.
Total amount: $51.84
Tip: 20%
Answer:
62.208
Step-by-step explanation:
51.84 + 10.368
Answer:
I think if the total amount was $51.84 after tax, then 51.84 x 0.20 = 10.368. $51.84 - 10.368 = $41.472
I think original price was $41.47. I am not sure.
