Answer:
54.7
Step-by-step explanation:
19% of 288
0.19 * 288 = 54.72
54.72 = 54.7
Answer:
Estimated 60 and rounded 55 and normal 54.72.
Step-by-step explanation:
To get the estimated answer, first convert the percentage to a decimal: 19% = 0.19. Second, you have to round the 2 numbers so they are easier to multiply: 0.19 = 0.20 and 288 = 300. Now that you have the 2 rounded numbers, you can multiply them to get the estimated answer: 0.20 x 300 = 60 so 60 is your estimated answer.
To get the rounded answer, you first have to multiply the 2 given numbers, the whole number and the percentage (as a decimal), together: 0.19 = 54.72. Now that you have the answer to the multiplication problem, you can round the answer to the nearest whole number: 54.72 = 55 so the rounded answer is 55.
To get the exact answer, all you have to do is multiply the percentage (as a decimal), by the whole number to get the answer: 0.19 x 288 is 54.72 so the exact answer is 54.72.

Two triangles are drawn in the coordinate plane. The vertices of the first triangle are (5, 4), (-4, 6), (-8, 9). The vertices of the second triangle are (1, 6), (-8, 8), (x, y). Find the value of x and y that allow these two triangles to be congruent.
The value of x and y that allows these two triangles to be congruent is
(-12, 11)
What are congruent triangles?The congruence of two or more triangles is determined by the measurements of their sides and angles. The three sides of a triangle determine its size, and the three angles determine its shape.
Two triangles are said to be congruent if the pairs of their corresponding sides and angles are equal. They are the same size and shape. Triangles have numerous congruence conditions.
Here we will use translation to find out units of displacements
If the triangle is congruent then vertices are of same shape too which means coordinate of first triangle will give us coordinate of second triangle
The coordinates of 1st vertices of traingle1 = (5, 4), x = 5, y = 4
The coordinates of 1st vertices of traingle2 = (1, 6), x = 1, y = 6
By subtracting,
translation x = 5 - 1 = 4
translation y = 4 - 6 = -2
Thus the vertices of other triangles are translated 4 units left and 2 units up. Same goes for second vertices
-4 - 4 = 8
6 + 2 = 8
And the same will go for the last vertices (-8, 9) that is
-8 - 4 = -12
9 + 2 = 11
The value of x and y that allow these two triangles to be congruent is (-12, 11)

Like terms have the same ______, with each variable raised to the same exponent
Answer:
variable
Step-by-step explanation:
Like terms are the terms that contain same variables raised to the same power, the coefficients need not be same. For example, 7x and 2x are like terms because both terms contain same variable "x".
If x varies inversely as y, then find the constant of variation if y = 9 and x =
8.
The constant of variation is 72.
Constant of Variation: What is it?In a direct variation, the constant of variation is the constant (unchanged) ratio of the two variables. The formula for direct variation is. where k is the variational constant and y=kx (or y=kx).
being that
x = 8
y = 9
If x varies in opposition to y, then
x*y = fixed
which means
x*y = k (where we assume constant as k) (where we take constant as k)
Inputting the values of x and y now yields,
8*9 = k
72 = k
Consequently, 72 is the constant of variation.

A hairdresser is making 4 hair bows. She needs 13/16 yards for each bow. If she has 6 1/8 yards of ribbon, how much will be leftover after making the bows?
Answer:
2 7/8 yards
Step-by-step explanation:
Given 6 1/8 yards of ribbon, you want the leftover amount after making 4 bows that use 13/16 yards each.
Quantity usedIf each of 4 bows takes 13/16 yards, the amount required for bows is ...
4×13/16 = 13/4 . . . . yards
Quantity remainingThe amount left over is the difference between the starting amount and the amount used:
6 1/8 - 13/4 = 49/8 -26/8 = 23/8 = 2 7/8
The hairdresser has 2 7/8 yards of ribbon remaining.

The first three terms of a geometric
sequence are 3, 6, 12.
The next three terms in the geometric sequence will be 24, 48 and 96.
We are given a geometric sequence:
3, 6, 12 …
We need to find the next 3 terms of the sequence.
We can see that:
a = initial term of the sequence
a = 3
r = common ratio between the consecutive terms.
r = 6 / 3 = 2
Now, nth term will be represented by:
aₙ = a rⁿ⁻¹
Substituting the values of a and r in the formula, we get that:
aₙ = 3 (2)ⁿ⁻¹
Now, the 4th term will be ( put n = 4)
a₄ = (3) (2)⁴⁻¹
a₄ = (3) (2)³
a₄ = (3) × (8)
a₄ = 24
The 5th term will be: (put n = 5)
a₅ = (3) (2)⁵⁻¹
a₅ = (3) (2)⁴
a₅ = (3) × (16)
a₅ = 48
6th term will be: (put n = 6)
a₆ = (3) (2)⁶⁻¹
a₆ = (3) (2)⁵
a₆ = (3) × (32)
a₆ = 96
Therefore, the next three terms in the geometric sequence will be 24, 48 and 96.

Answer:
[tex]y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
Step-by-step explanation:
Given equation:
[tex]\pi=7x-2y[/tex]
To isolate y, add 2y to both sides:
[tex]\implies\pi+2y=7x-2y+2y[/tex]
[tex]\implies\pi+2y=7x[/tex]
Subtract π from both sides:
[tex]\implies\pi+2y - \pi=7x- \pi[/tex]
[tex]\implies 2y=7x- \pi[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{2y}{2}=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
[tex]\implies y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
This can also be written as a rational function:
[tex]\implies y=\dfrac{7x- \pi}{2}[/tex]
Answer:
y = (-π + 7x)/2
Step-by-step explanation:
Now we have to,
→ find the required value of y.
The equation given is,
→ π = 7x - 2y
Then the required value of y will be,
→ π = 7x - 2y
→ -2y = π - 7x
→ y = (π - 7x)/(-2)
→ [ y = (-π + 7x)/2 ]
Hence, the equation is (-π + 7x)/2.

Round your answer to two decimal places.
The water in gallons to entirely fill the swimming pool is 51705.344 gallons.
What is defined as the conversion factor?A conversion factor is an amount that is used to multiply or divide one set of units into another. When converting to an equal value, the suitable conversion factor must be used. To convert inches to feet, for example, the adequate conversion amount is 12 inches equal 1 foot.For the given question;
The volume of the pool = 256 yd³.
Convert the volume in yd³ in gallons.
1 yd³ = 201.976 gallons.
Thus, for the total volume of 256 yd³ multiply both side with 256.
1×256 yd³ = 201.976×256 gallons.

The following table shows the average total cost, measured as dollars expended per pupil, of operating a high school with the given enrollment. This table is based on a study of economies of scale in high school operations from the 1960s.
Enrollment: 170 250 450 650
Average total cost: 538 473 411 415
Estimate the average cost per student for a high school with an enrollment of 350 students.
The interpolated value for an enrollment of 350 students is $ ------
per student.
Answer:
$433
Step-by-step explanation:
You want the average cost per student for an enrollment of 350 students as interpolated from a table of enrollments and costs.
InterpolationThere are a number of ways the cost table might be interpolated. The one used here is to use quadratic regression to write a formula for the cost as a function of enrollment. Then the function value for 350 students is found. This is all accomplished using a graphing calculator, as shown in the attachment. The interpolated value for an enrollment of 350 students is $433 per student.
Another method of interpolation could use linear interpolation between the two nearest points. Our enrollment of interest, 350, is halfway between 250 and 450, so the cost per student could be estimated to be halfway between 473 and 411:
cost per student = (473 +411)/2 = 442 . . . dollars per student
We know this estimate is a bit high, because the cost function is concave upward. A straight line between two points on the curve will lie above the curve.
Other methods of interpolation will give other values. A cubic interpolating function gives a value of $428 per student.
