8. An car can hold 8 1/4 gallons of fuel. It contains 4 5/6 gallons of fuel. How
much more fuel is needed to fill the car?
Answer:
3 5/12
Step-by-step explanation:
Answer:
41/12 gallons
= 3 5/12 gallons
Step-by-step explanation:
Since it can hold 8 1/4 gallons and currently has 4 5/6 gallons, you subtract.
You need to get the common denominator to subtract cleanly so we can turn the fractions into improper fractions.
8 1/4 = 33/4 because 8 is equal to 8 full 4/4ths so multiply 8 by 4 and add 1 for the remaining 1/4.
Then 4 5/6 becomes 29/6 with the same concept earlier.
So we can change the denominator to 12 on both fractions (33/4 and 29/6) so we can subtract.
33/4 becomes 99/12 because they are still equivalent, it's just that you multiplied the top and bottom by the same number.
29/6 becomes 58/12 because we multiplied the fraction by 2/2.
Those two new fractions stated previously are the same as the original because we multiplied them by 1/1, because 3/3 and 2/2 is still equal to 1/1, and the new fractions can be simplified down to the original.
Since we have 99/12 and 58/12, we can subtract cleanly into
99 - 58 = 41
So the answer is 41/12
Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris' age is 66. How old is Beatrice?
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9

How are differences between the sample mean and the population mean explained when the result isn't statistically significant?
Answer and explanation:
The standard error is used to measure the difference between the sample mean and the population mean. It uses standard deviation to measure the level of deviation of the sample mean from the population mean. In other words, the accuracy of the sample mean by way of representing the mean of the population is measured using the standard error. If there is significant difference then standard error is bigger usually non-zero while it is less significant with smaller standard error.

Question 6 options:
A sphere with a volume of 1200 cm³ is dilated by a factor of 3/5.
The volume of the dilated image is ___ cubic centimeters.
Express your answer to the nearest whole unit.
Given:
Volume of sphere = 1200 cm³
The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex].
To find:
The volume of the dilated image.
Solution:
If two figures are similar then their volumes are proportional to cube of their corresponding sides.
We know that all sphere are similar to each other.
The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex]. It means the ratio of new figure to original figure is
Let [tex]V_1[/tex] be the volume of original figure and [tex]V_2[/tex] be the volume of dilated figure.
[tex]\dfrac{V_2}{V_1}=\left(k\right)^3[/tex]
Where, k is the scale factor.
[tex]\dfrac{V_2}{1200}=\left(\dfrac{3}{5}\right)^3[/tex]
[tex]\dfrac{V_2}{1200}=\dfrac{27}{125}[/tex]
Multiply both sides by 1200.
[tex]V_2=\dfrac{27}{125}\times 1200[/tex]
[tex]V_2=259.2[/tex]
[tex]V_2\approx 259[/tex]
Therefore, the volume of the dilated image is 259 cubic centimetres.

[Q] Mike and Jeanie played 38 games of checkers. Mike won 6 more games than Jeanie. To find out how many games Jeanie won a student used this equation.
M + J = 38
In this equation: M = number of games Mike won and J = number of games Jeanie won Which other equation would help the student to solve this problem?
(A) 38 - 6 = J
(B) M - J = 6
(C) 38 + 6 = J
(D) J - M = 6
(E) M + J = 6
Answer:
(B) M - J = 6
Step-by-step explanation:
Here we have the variables:
M = number of games that Mike won.
J = number of games that Jeanie won.
And we know that there is a total of 38 games played, then if a game can not end in a draw, we have the equation:
M + J = 38
Now we want to find the other equation needed to solve this problem:
We also know that Mike won 6 more games than Jeanie, this is written as:
M = J + 6
We can subtract J in both sides to get:
M - J = 6
This is the equation from option B, so we can conclude that the correct option is B.

Classify the following triangle. Check all that apply
Step-by-step explanation:
it's a right angled triangle
it's also a scalene triangle because not all sides are equal
does 32, 57, 65 form a right triangle?
Answer:
No
Step-by-step explanation:
In order to form a right triangle, you would need one of the angles to be 90 degrees. Plus all the angles don't equal 180 degrees (the angles of a triangle should add up to 180)

Both of your answers are correct
Step-by-step explanation:
Answer:
d
e
Step-by-step explanation:
2x ≤ 5x - 15
step 1 subtract 5x from each side
2x - 5x = -3x
5x - 5x cancels out
we now have -3x ≤ -15
step 2 divide each side by -3
-3x / -3 = x
-15 / -3 = 5
IMPORTANT NOTE ( when you divide by a negative number you must flip the sign )
We would be left with x ≥ 5
now let's Plug in 10
2(10) ≤ 5(10) - 15
2(10) = 20
20 ≤ 5(10) - 15
5(10) = 50
20 ≤ 50 - 15
50 - 15 = 35
20 ≤ 35 ✓

What is the length of the missing side of the larger triangle?
Answer:
B
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{?}{6}[/tex] = [tex]\frac{18}{12}[/tex] ( cross- multiply )
12 ? = 108 ( divide both sides by 12 )
? = 9 → B
Which of the following theorems verifies that XYZ - UWV
A. HL
B. AA
C. LL
D. HA
Given:
The figure of two triangle XYZ and UWV.
To find:
The theorem that is used to verify [tex]\Delta XYZ\sim \Delta UWV[/tex].
Solution:
In triangle XYZ,
[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex] (Angle sum property)
[tex]70^\circ+90^\circ+m\angle Z=180^\circ[/tex]
[tex]160^\circ+m\angle Z=180^\circ[/tex]
[tex]m\angle Z=180^\circ-160^\circ[/tex]
[tex]m\angle Z=20^\circ[/tex]
In triangle XYZ and triangle UWV,
[tex]m\angle Y\cong m\angle W[/tex] (Right angles)
[tex]m\angle Z\cong m\angle V[/tex] (Equal measures)
Two angles of one triangle are congruent to corresponding angles of another triangle. So, the triangles are similar by AA property of similarity.
[tex]\Delta XYZ\sim \Delta UWV[/tex] (AA similarity theorem)
Therefore, the correct option is B.
calcula la longitud de la variable "x"
Answer:
La longitud de [tex]x[/tex] es [tex]5\sqrt{2}[/tex] unidades.
Step-by-step explanation:
La figura es un cuadrado atravesado por una diagonal, significando que existen dos triángulos rectángulos, cuyos ángulos interiores son 45°, 45° y 90°, respectivamente. Por Geometría Euclideana, tenemos que la longitud de la hipotenusa es igual a [tex]\sqrt{2}[/tex] veces la longitud de cualquiera de sus catetos:
[tex]x = \frac{10}{\sqrt{2}}[/tex]
[tex]x = 5\sqrt{2}[/tex]
La longitud de [tex]x[/tex] es [tex]5\sqrt{2}[/tex] unidades.
4. A rental car costs a one time fee of $180 and then an additional $65 for each day it is
rented. If the Neddles family's total bill was $520, how many days did they rent the car?
Answer:
5.23 =d
Step-by-step explanation:
cost = fee + daily charge*days
520 = 180+ 65d
Subtract 180
520 -180 = 180+65f-180
340 = 65d
Divide by 65
340/65 = 65d/65
5.23 =d

How many snacks are in one pack of granola bars and one pack of fruit rolls?
Answer:
There are 8 granola bars in a pack and 12 fruit rolls in a pack.
Step-by-step explanation:
10x+6y=152
5x+3y=76
7x+12y=200
-20x-12y=-304

An angle measures 52° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
64º and 116º
Step-by-step explanation:
x + (x - 52) = 1080
2x - 52 = 180
2x = 232
x = 116º
x - 52 = 64º
