Answer:
525 in³
Step-by-step explanation:
Use the direct variation equation, y = kx.
Substitute y with v (volume) and substitute x with l (length) to represent this situation:
y = kx
v = kl
Plug in 35 as l and 15 as k, then solve for v (the volume):
v = kl
v = 15(35)
v = 525
So, the volume of the box is 525 in³

What is the value of the interquartile range of the data below? A box-and-whisker plot. The number line goes from 0 to 52. The whiskers range from 10 to 51, and the box ranges from 29 to 41. A line divides the box at 32. 6 12 14 24
Answer:
12
Step-by-step explanation:
The interquartile range is the difference between the lower quartile and the upper quartile
We can find the quartiles at the beginning and the end of the box
At the beginning of the box, we have the lower quartile, while at the end, we have the upper quartile
from what we have ;
The lower quartile is 29 while the upper quartile is 41
So the difference between the two which is the interquartile range is ;
41-29 = 12

Solve for the unknown angles. Justify your answers with steps (do not just provide answers)
Answer:
PNQ=117
LKQ=102
Step-by-step explanation:
LKQ=180-78=102
KQN=180-67=113
LNQ=360-82-102-113=63
PNQ=180-63=117
Answer:
∠ LKQ = 102°, ∠ PNQ = 117°
Step-by-step explanation:
∠ LKQ = 180° - 78° = 102° ( adjacent angles on a straight line )
∠ KQN = 180° - 67° = 113° ( adjacent angles on a straight line )
The sum of the interior angles of a quadrilateral = 360° , then
∠ LNQ = 360° - (102 + 113 + 82)° = 360° - 297° = 63°
Then
∠ PNQ = 180° - 63° = 117° ( adjacent angles on a straight line )

Answer: IT IS CONGRUENT BY ASA POSTULATE.
Step-by-step explanation:
ACCORDING TO THE GIVEN IMAGE
CONSIDER TRIANGLE 1 AS TRIANGLE ABC AND TRIANGLE 2 AS TRIANGLE PQR
IN TRIANGLE ABC AND PQR
ANGLE B = ANGLE C ( 90 DEGREES )
AC = PR ( GIVEN IN FIGURE )
A TRIANGLE HAS SUM OF INTERIOR ANGLES AS 180 DEGREES
IF ANGLE B AND ANGLE Q ARE 90 DEGREES, ANGLE A + ANGLE C = ANGLE P + ANGLE R
WE HAVE ALREADY PROVED THAT AC = PR
If two triangles have one angle equal to one angle, two sides adjoining the equal angles equal, namely, one side adjoining the equal angles, and one opposite the equal angles, and the remaining angles either both less or both not less than a right angle, then the remaining side equals the remaining side and the remaining angles equal the remaining angles.
SO ANGLE A = ANGLE P
THEREFORE BY ASA CONGRUENCY TRIANGLE ABC IS CONGRUENT TO TRIANGLE PQR

Find side b, in triangle ABC. if angle B =42 degrees, a=6, c=4
Answer:
There is no valid value for b
Step-by-step explanation:
We solve the above question using the law of cosines
b² = a² + c² - 2ac × Cos B
B = 42°, a = 6, c = 4
b² = 6² + 4² - 2 × 6 × 4 × Cos 42
b =√6² + 4² - 2 × 6 × 4 × Cos 42
b = √36 + 16 - 48 × Cos 42
Solving the above question, there is no valid value for b

F(x) = 6x+2, find f (x+3)
Answer:
6x+20
Step-by-step explanation:
F(x) = 6x+2
f(x+3) means replace x with x+3
F(x+3) = 6(x+3)+2
= 6x+18+2
= 6x+20
Answer:
A; F(x+3) = 6x^2 + 20x + 6
Step-by-step explanation:
To find it you just would multiply F(x) onto the other side. So it would look like this:
F(x+3) = 6x + 2 (x+3)
F(x+3) = 6x^2 + 2x + 18x + 6 *combine like terms getting you
F(x+3) = 6x^2 + 20x + 6

10 POINTS!! PLEASE HELP!!
Answer:
only the third answer is right.
Step-by-step explanation:
to solve it, we need to bring everything to the same denominator (the expression below the division line) or eliminate it completely.
how do we do it ? by multiplying everything with the same expression, so that we can eliminate the denominator for every term.
when looking for the best option I see that
(x² + 5x + 6) = (x + 2)×(x + 3)
that is great, because this covers all 3 denominators in our main expression.
so, we multiply everything by ((x+2)×(x+3)) and eliminate the denominators and the corresponding part of our multiplier.
that leaves us with
x×(x+3) + 2 = 5×(x+2)
now we simply simplify the expression
x² + 3x + 2 = 5x + 10
x² - 8x - 8 = 0
a squared equation has typically 2 solutions. and they are defined as
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = -8
c = -8
x = (8 ± sqrt(64 + 32)) / 2 = (8 ± sqrt(96))/2 =
= (8 ± sqrt(16×6))/2 = (8 ± 4×sqrt(6))/2 = 4 ± 2×sqrt(6)
x1 = 4 + 2×sqrt(6)
x2 = 4 - 2×sqrt(6)
both solutions are different from -2 or -3, therefore -2 and -3 are not solutions at all, and they cannot be extraneous solutions either for that reason.
and since we have 2 perfectly fine solutions, the answer options work no or only one solutions are wrong too.

The angle measure of angle ∠1 is 31°.
The correct option is C.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given information:
The circle is centered at y.
As per the provided diagram,
The angle measure of an arc let a = 37°.
And b = 25°.
To find the angle measure of ∠1:
Apply formula (a + b)/2,
So as per the provided values of a = 37° and b = 25°.
Therefore,
m∠1 = (37 + 25)/2
m∠1 = 62/2
m∠1 = 31°.
Therefore, m∠1 = 31°.

Answer:
1: (C)
2: (C)
3: (D)
4: (A)
5: (D)
Step-by-step explanation:
1: "Which could be the entire interval over which the function, f(x), is negative?"
When f(x) is negative, that means the values under the f(x) column is negative. As you can see, -16 & -8 are the only times when f(x) is negative. To find the interval, we are going to use x-values. Notice how as x continues to decrease, f(x) also decreases. So the answer is (-infinity, -6).
2: "Which equation represents the graphed function?"
Looking at the graph, we see that the y-intercept is (0, -2). However, all the answer choices have the correct y-intercept, so now we must focus on getting the correct slope. The slope is positive, so the answer is either (A) or (C). To find the correct answer, use the rise/run method from (0, -2) to (4, -1). You rise 1 and run 4, so the slope is 1/4. The answer is y = 1/4x - 2.
3: "If f(1) = 10, what is f(3)?"
I honestly don't know how to do this one. I looked it up on Brainly and some other people said the answer is 30. Credits to dragonheartedking on Brainly.
4: "Which table represents a linear function?"
Table A represents a linear function because each time x increases by 1, y increases by the same amount of 4 each time. It doesn't fluctuate like the rest of the answer choices.
5: "How many units below the y-intercept of g(x) is the y-intercept of f(x)?"
The y-intercept is the point where the function intersects with the y-axis. We start from (0, 2) and count the units as we reach (0, -1). The answer is 3 units.

and
2x+3 = 7 ( be careful not to switch sides or the arrow switches too)
the the top equation looks like
-8=2x
-8/2 = x
-4 =x
the bottom equation looks like
2x = 4
x = 4/2
x = 2
now put it back together with the arrows in the same direction :) ( we don't have to worry about switching directions of the arrows b/c we didn't switch side, multiply or divide by a negative, so all good :P)

Answer:
Yes Ella has enough to make 30 mince pies
Step-by-step explanation:
Step-by-step explanation:
to make 36 mince pies you will need
400g of butter
500g of flour
300g of sugar
500g of mince meat
2 eggs
Ella has 1000g of butter
1000g of flour
500g of sugar
600g of meat
6 eggs
these ingredients are more than enough because
1000g-400g=600g-butter
1000g-500g=500g flour
500g-300g=200g sugar
600g-500g=100g mince meat
6-1= 5 eggs
if she were to follow the 36 pie recipe, which is two times the 18 pie recipe
but like I don't know, because it says a recipe for 18 mince pies, but in the box it says 12
Use the Factor Theorem to prove x^3 - 13x - 12 is divisible by x^2 – X – 12
Answer:
See Below.
Step-by-step explanation:
We want to prove that:
[tex]x^3-13x-12\text{ is divisible by } x^2-x-12[/tex]
We can factor the divisor:
[tex]x^2-x-12=(x-4)(x+3)[/tex]
According to the Factor Theorem, if we have a polynomial P(x) divided by a binomial in the form of (x - a) and if P(a) = 0, then the binomial is a factor of P(x).
Our two binomial factors our (x - 4) and (x + 3). Thus, a = 4 and a = -3.
Evaluate the polynomial for both of these factors:
[tex]P(4)=(4)^3-13(4)-12=0[/tex]
And:
[tex]P(-3)=(-3)^3-13(-3)-12=0[/tex]
Since both yielded zero, the original polynomial is divisible by both (x - 4) and (x + 3) or x² - x - 12. Hence:
[tex]x^3-13x-12\text{ is indeed divisible by } x^2-x-12[/tex]
