Answer:
7 cubic feet
Step-by-step explanation:
so first you do length times height in this case it would be 16 times 8
you get 128 now you divide 896 by 128 and you get an answer of 7.
One way to check is you do length times width times height.
So 16 × 7 × 8 =896
Answer: 7 feet cubed

During a basketball game, you made 11 shots of either 2 or 3 points. You scored a
total of 25 points. How many shots of each point value did you make?
Let
x -----> number of shots of 2 points
y -----> number of shots of 3 points
we have that
x+y=11
x=11-y -----> equation A
and
2x+3y=25 -----> equation B
substitute equation A in equation B
2(11-y)+3y=25
solve for y
22-2y+3y=25
y=25-22
y=3
Find the value of x
x=11-3
x=8
therefore
number of shots of 2 points is 8number of shots of 3 points is 3A tanker truck fills the gas station’s reservoir at the rate of 1212 gallons per minute.
If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir?
The tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute using the estimation concept.
As per the question statement, A tanker truck fills the gas station’s reservoir at the rate of 1212 gallons per minute and the reservoir was empty and it is now 35 gallons full. We are supposed to find out for how long has the tanker been filling the reservoir. We will use the concept of estimation.
Rate of filling gas = 1212 gallons per minute
i.e., 1212 gallon of gas taken 1 minute for transfer.
1 gallon of gas will take = (1/1212) minutes
Hence 35 gallons of gas will take = (1/1212)*35 minutes = 0.0288 min.
So, the tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute.

A kite is shown below. What is the length of LINE AC? (image attached)A. 4B. 6C. 9D. 10
The length of AC is given by AE + EC
According to the Pythagorean Theorem, we know that:
AE² = AD² - ED²
AE² = 5² - 3²
AE² = 25 - 9
AE² = 16
AE = 4
EC² = DC² + ED²
Since DC = BC, we have:
EC² = BC² + ED²
EC² = 45 - 9
EC² = 36
EC = 6
Therefore, AC = 4 + 6 = 10

Answer:

Step-by-step explanation:
i did it
The total area for the parallelogram-shaped tiles Felix needs to buy exists 80cm² at the price of $40.
What is meant by the area of parallelogram?In calculating the area of a parallelogram, the base exists multiplied by the height, in an exact way as computing the area of a rectangle.
Given that, the base of one parallelogram-shaped tile exists 4cm with a height of 2 cm.
Area of one parallelogram shaped tile = 4cm × 2cm
Area of one parallelogram-shaped tile = 8cm²
Total area for the 5black and 5white tiles = 10 × 8cm²
Total area for the 5black and 5white tiles = 80cm²
Therefore, Felix must buy a total area of 80cm² of 10 parallelogram-shaped tiles.

She cannot afford to buy the car with monthly instalments of $350. She needs to make a downpayment of $856.44 to afford the car
The total amount of the car loan = 13456.44
Number of instalments = 36 monthly payments
Affordable installment per month = $350
EMI: A fixed payment is made by a borrower to a lender at a specific time each month, known as an equated monthly instalment (EMI). The loan is repaid in full over a predetermined period of time by making equal monthly payments to the principal and interest.
Total payment that can be made using the instalments = Monthly instalments * Number of instalments
= 350*36
Total payment that can be made using the instalments = 12600
The amount remaining after paying instalments = 13456.44 - 12600

The given function is increasing over these following intervals:
B. -2 ≤ x ≤ -1.
C. 0 < x < 1.
Where to find where a function is increasing, from it's graph?Considering the graph of the function, we get that a function f(x) is increasing when it is "moving northeast", that is, to the right and up on the graph, meaning that when x increases, y increases.Conversely, we get that a function f(x) is decreasing when it is "moving southeast", that is, to the right and down the graph, meaning that when x increases, y decreases.Considering the given definitions on the bullet points above, the behavior of the function can be separated as follows:
Increasing on -2.5 ≤ x ≤ 2.5.Decreasing on all other intervals except the one above.Items B and C have subsets of the interval -2.5 ≤ x ≤ 2.5, hence the function is increasing on those intervals, and they are the correct options for this problem.

EXPLANATION
Let's see the facts:
The angles of symmetry in point A is 60 degrees because the plane in point A is divided in 6 parts, so dividing 360° by 6 give us 60°. The same reasoning applies for the point B dividing it by 3 parts.
The angles of symmetry in point B is 120 degrees.

ý = 9.996 + 0.355x
Predict the years of education for a person whose father had 14 years of education. Round to
the nearest whole number.
The years of education as per the given equation, for a person whose father had 14 years of education is 14.966 years.
What is education?
A planned activity, education has objectives like knowledge transmission or character and skill development. The development of understanding, reason, kindness, and honesty may be some of these goals.
As given in the question,
respondent's years of education is represented by y, and
respondent's father years of education is represented by x,
The equation for the least squares regression line for predicting a respondent's years of education is given as:
y = 9.996 + 0.355x
The year of education of respondent's father is given as 14
So putting the value of x in the given equation as 14:
we get,
y = 9.996 + 0.355(14)
y = 14.966
Hence, the years of education for a person whose father had 14 years of education is 14.966 years.

A triangle, ABC, has angle measures of 45°, 45°, and 90° and two congruent (equal) sides. How would this triangle be classified?
O Isosceles acute
O Scalene acute
O Scalene right
O Isosceles right
Answer:
(d) Isosceles right
Step-by-step explanation:
You want to know the classification of a triangle with angles 45°-45°-90°.
ClassificationThe largest angle is 90°, a right angle. Any triangle containing a right angle is a right triangle.
Two of the angles have the same measure. This means the triangle is an isosceles triangle.
The triangle is classified as an isosceles right triangle.
__
Additional comment
A triangle whose largest angle is less than 90° is an acute triangle. If the largest angle is greater than 90°, it is an obtuse triangle.
If no sides are the same length, the triangle is scalene. If two sides are the same length, the triangle is isosceles. If all three sides are the same length, it is an equilateral triangle.
Larger angles are opposite longer sides, so if angles are the same, their opposite sides are the same.
It can be worthwhile to remember that the side length ratios in an isosceles right triangle are 1 : 1 : √2.

What is the compound interest?The practice of adding interest to the principal amount of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. Reinvesting interest, or adding it to the lent capital rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus interest collected previously.

P equals the initial principal amount.
The nominal yearly interest rate is r.
The compounding frequency is n.
t is the total amount of time that the interest is charged (expressed using the same time units as r, usually years).
The final value less the beginning investment yields the entire compound interest.

Given one line, to find another one perpedicular to it, you have to keep in mind that the slope of the perpedicular line is the negative inverse of the slope of the first one, that is:
Let the given line be:

Find sin(2x), cos(2x), and tan(2x) from the given information.
tan(x) = − 4/3 , x in Quadrant II
Answer:
Step-by-step explanation:
Starting from tan x, you can find sec x, because of the trigonometric identity 1 + tan2 x = sec2 x.
1 + (-4/3)2 = 1 + 16/9 = 25/9 = sec2 x.
So sec x = ±√(25/9) = ±5/3. But since x is in Quadrant II, sec x has to be negative. That's because sec x has the same sign as cos x, because sec x = 1 / cos x. We know that cos x is negative is Quadrant II, therefore so is sec x. So sec x = -5/3.
Since sec x and cos x are reciprocals of each other, cos x = 1/sec x = -3/5.
Now use the identity sin2 x + cos2 x = 1, to find sin x:
sin2 x + (-3/5)2 = 1
sin2 x + 9/25 = 1
sin2 x = 16/25
sin x = ±4/5
Again, we know that sin x is positive in Quadrant II, so sin x = 4/5.
Now that we know sin x and cos x, we can use the double angle formulas to find sin 2x and cos 2x.
sin 2x = 2 sin x cos x = 2 (4/5) (-3/5) = -24/25
cos 2x = cos2 x - sin 2 x = (-3/5)2 - (4/5)2 = 9/25 - 16/25 = -7/25
Finally use the identity tan x = sin x / cos x to find tan 2x:
tan 2x = sin 2x / cos 2x = (-24/25) / (-7/25) = -24/-7 = 24/7
