Answer:
28
Step-by-step explanation:
2 x 7 = 14
Number should be in between 26 and 31
So,
14 x 2 = 28
28 has one of its prime factors as 2 and 7.
Hence,
28 is the number which is in between 26 and 31 it has the prime factors of 2 and 7.
Answer:
Step-by-step explanation: Given prime factors: 2, 7
By multiplying, 2 X 7= 14
Given, number is between 26 and 31
therefore, 14 X 2= 28 (since 2 is a prime factor)

Darlene has 6 3/4 gallons of gasoline. Every time she mows her lawn, she uses 3/8 gallon. How many times can she mow her lawn before she needs more gas?w
The number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.
As given in the question,
Total gasoline with Darlene is equal to 6 3/4 gallons
Convert mixed fraction into proper fraction:
6 3/4 = 27/4 gallons
Every time amount of gasoline used to mow her lawn = 3/ 8gallon
Number of times Darlene mow her lawn before she needs more gasoline
= (27 / 4) ÷ (3 /8)
= (27 /4) × (8/3)
= 18 times
Therefore, the number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

What is opposite side of a right-triangle?
From a particular angle, the opposite side is across. The legs of a right triangle are its adjacent and opposite sides, together, they make up the triangle. The opposing (shorter) side is the side that is shorter and perpendicular to the angle from which you are observing it.The angle from which we are looking does not include this side.An opposite side in a right triangle is the one that is across from a given angle, while an adjacent side is the one that is next to a given angle and the hypotenuse is the longest side in a right triangle.To learn more about opposite side, refer:

Step-by-step explanation:
Using a graph typing in 9x and looking at the table, (2,1) is not on the table, so (2,1) is not a solution to 9x
Answer:
No
Step-by-step explanation:
to determine if (2, 1 ) is a solution, substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it is a solution.
y = 9x ( substitute x = 2 )
y = 9 × 2 = 18 ≠ 1
then (2, 1 ) is not a solution to the equation.
The cost of manufacturing a cake is directly proportional to the volume of the cake.
The baker makes a 70% profit when he sells a large rectangular cake.
The baker sells a large rectangular cake for £6.80 The baker decides to sell smaller rectangular cakes.
The length, width, and height of the smaller cakes are all half of those of the large rectangular cake.
He sells a pack of 6 of the smaller cakes for £6.50
How much profit does he make on the pack of smaller cakes?
Answer:
The baker makes £3.50 profit on smaller cakes================================
GivenLarge cake:
Price = £6.80,Profit = 70%Small cake:
Number = 6,Price = £6.50,Dimensions = each side is 1/2 of the large cakeSolutionThe profit is the difference of the cost and selling price.
Find the cost x of large cake:
x + 70% = 6.801.7x = 6.80x = 4Find the volume of the pack of smaller cakes, taking the volume of the large cake as a unit:
6*(1/2)³ = 6*1/8 = 3/4Cost of the pack of smaller cakes is proportional to the volume:

In ΔTUV, UV = 14, VT = 19, and TU = 9. Which statement about the angles of ΔTUV must be true?
In ΔTUV, UV = 14, VT = 19, and TU = 9, The statement about the angles of ΔTUV that must be true is [tex]m \angle U > m \angle T > \angle V[/tex] Option 5
This is further explained below.
What are angles?Generally, A triangle's angle is a measurement of the length of the side that is perpendicular to it.
This indicates that if one of the sides is longer in length, then the measure of the angle opposite to it will also be longer.
The angles in the triangle TUV are denoted by the symbols T, U, and V.
The side that is UV, TV, and T U correspondingly is the side that is opposite to these angles.
The length of the opposing sides will immediately determine the measure of the angles, which will be directly proportionate to those angles.
since V T>U V>T U, the arrangement of angles will correspond to this as follows: [tex]m \angle U > m \angle T > \angle V[/tex] Option 5

Find the future value, using the future formula and a calculator. (Round your answer to the nearest cent.)$901 at 3.5% compounded semiannually for 6 years
To calculate the future value we need to use the compound formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where P is the principal, r is the interest rate in decimal form, n is the number of times the interest is compound in any given time t.
In this case we have that P=901, r=0.035 and since the interest is compound semiannually this means that n=2. Finally t=6. Plugging this values into the equation above we have that:

The ordered pair for A' is (5, -3).The ordered pair for B' is (-2, 7).The ordered pair for C' is (8, 8).The ordered pair for D' is (10, 4).What is a rotation?A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise direction.
In Mathematics, rotating a point 90° about the origin in a clockwise or counterclockwise direction would produce a point that has the coordinates (y, -x).
By applying a rotation of 90° clockwise to square ABCD, the coordinate of the image of square A'B'C'D' is given by:
(x, y) → (y, -x)
Points at A = (-3, 5) → Points at A' = (5, -(3)) = (5, -3)
Points at B = (-7, -2) → Points at B' = ((-2), -(-7)) = (-2, 7).
Points at C = (-8, 8) → Points at C' = (8, -(-8)) = (8, 8).

Term Value 6 10 14 18 22 26
What are the term values?In order to determine the term values, the rate of increase in the number of videos that Violet has at the end of each week has to be determined.
Rate of increase in the number of videos can be determined by dividing the change in the number of videos per week by the change in the number of weeks.
Rate of increase = change in the number of videos / change in the number of weeks

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf greek students have in a one week period. We know from preliminary studies that the standard deviation is around 6. 3. How many students should be sampled to be within 0. 5 drink of population mean with 95% probability?.
Number of students need to be sampled = 610
A study to determine the true average number of alcoholic drinks consumed by Greek students is conducted.
Standard Deviation, σ = 6.3
Margin Error of population mean, E = 0.5
Probability = 95% = 0.95
The p-value corresponding to 0.95 probability = (1+0.95)/2 = 0.975
The z-score corresponding to this p-value = 1.96 [from the z-tables]
Now, The margin error, E = zσ/√n, where n is the sample size
⇒ n = (zσ/E)²
⇒ n = (1.96 x 6.3/0.5)²
⇒ n ≈ 610
Hence 610 students need to be sampled.

A parent function's graph is altered by a translation. The three different types of translation are dilations, reflections, and translations.
A function can have its y-values modified vertically or its x-values changed horizontally (affects the x-values).
We are aware that the x- and y-coordinates must be modified to reflect the translation by the specified amount.

Riley and Paul go to the driving range. Together, they hit 75 balls. Riley hit 17 more than Paul. How many
balls did each of them hit?
Riley hit 46 balls and Paul hit 29 balls at the driving range.
According to the question, let
Number of balls hit by Riley be x
Number of balls hit by Paul be y
Together Riley and Paul hit 75 balls
∴x+y=75 (1)
Riley hit 17 more balls than Paul
∴x= y + 17 (2)
Now we have to solve these simultaneous linear equations (1) and (2)
Replacing the value of x from equation (2) into equation (1) we get,
y+17+y=75
⇒2y + 17 = 75
⇒2y = 75 - 17
⇒2y = 58
⇒y = 58/2 (dividing both sides by 2)
⇒y = 29
∴No. of balls hit by Riley = x = y +17 = 29 + 17 = 46 (from equation (2))
Therefore, Riley hit 46 balls and Paul hit 29 balls at the driving range.
