Answer $625:
Step-by-step explanation:
Since the discount is 24% that means that $475 is 76% of the total
X is the 100% of the price (before sale)
475...............76%
x..........................100%
cross multiplication
76x = 475x100
76x = 47500
Divide both sides by 76
x= 625
A box in the shape of a triangular prism is painted for a project. Which formula would be used to find the lateral surface area of the triangular prism?
Answer:
LSA = (a+b+c)×h
Step-by-step explanation:
The formula that would be used to find the lateral surface area of the triangular prism = perimeter of base(P) × Height of prism(H)
Let us assume that three side of triangle are a, b, c and height of prism is h
Then lateral surface area of the prism can be LSA = (a+b+c)×h

Answer:
DCB=33
Step-by-step explanation:
We are given the angle for a and we know the angle for ADC is 90 because AB & DC are perpendicular. Given two angles of a triangle we can find the third by subtracting the two known values from 180 because we know a triangle totals 180.
180-33-90=57
So we can also find CDB because we know AB & DC are perpendicular. It is also 90 because two perpendicular lines make a 90 angle.
DCB can be found because we know that ACB makes a 90 angle and the ACD portion is 57. So we subtract 57 from 90.
90-57=33
We can also find CBD by subtracting CDB and DCB from 180.
180-90-33=57

Find the possible values of k if one of the roots of the quadratic equation x^2 - kx + 8 = 0 is twice the other.
Answer:
[tex]k=\pm 6[/tex]
Step-by-step explanation:
The given quadratic equation is :
[tex]x^2 - kx + 8 = 0[/tex]
One of the roots of this equation is twice that of the other. Let the roots are [tex]\alpha \ and\ \beta[/tex], [tex]\alpha =2\beta[/tex]
Sum of roots, [tex]\alpha +\beta =\dfrac{-b}{a}[/tex]
[tex]\alpha +\beta =\dfrac{-(-k)}{1}\\\\\alpha +\beta =k\\\\3\beta =k\ .......(1)[/tex]
Product of roots,
[tex]\alpha \beta =\dfrac{c}{a}\\\\2\beta ^2=\dfrac{8}{1}\\\\\beta =\pm 2[/tex]
If [tex]\beta =\pm2[/tex],
[tex]k=3(2)\\\\=\pm 6[/tex]
So, the value of k is equal to [tex]\pm 6[/tex].

Bill has 5 liters of water to pass out to his teammates at the basketball game. If one player drinks 1000 milliliters, two players drink 500 milliliters, and another player drinks 2000 milliliters, how much water does Bill have left at the end of the game?
A. 1,000 liters
B. 2 liters
C. 10,000 liters
D. 1 liter
Answer:
D. 1 liter
Step-by-step explanation:
1000 milliliters = 1 liter
Player 1: 1000 ml or 1 liter
Player 2: 500 ml or .5 liter
Player 3: 500 ml or .5 liter
Player 4: 2000 ml or 2 liter
Add: 1 + .5 +.5 +2 = 4
Subtract: 5 - 4 = 1
Answer: You have 1 liter left
0/1 Solve the equation by completing the square. Round your answer to the nearest hundredth, if necessary x^2+18x=7
Answer:
The solution to the equation is x = 0.38 or -18.38
Step-by-step explanation:
x^2+18x=7 can be properly written as
[tex]x^{2} +18x =7[/tex]
To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides
i.e 18/2 = 9
Then add 9² to both sides of the equation
[tex]x^{2} +18x + 9^{2} = 7 + 9^{2}[/tex]
This becomes
[tex](x+9)^{2} = 7 + 81[/tex]
[tex](x+9)^{2} = 88[/tex]
[tex]x+9 = \pm \sqrt{88}[/tex]
[tex]x = -9 \pm\sqrt{88}[/tex]
[tex]x = -9 \pm 9.38[/tex]
∴ [tex]x = -9+9.38 or -9-9.38[/tex]
[tex]x = 0.38 or -18.38[/tex]
Hence, x = 0.38 or -18.38

Tiffany scored 80 on the exam.
Find the Z-score for Tiffany's exam grade. Round to two decimal places.
Answer:
0.85
Step-by-step explanation:
The Z-score for Tiffany's exam grade will be 0.85. The value of Z score for the different distribution is different.
What is the z score?The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
The Z score is found as;
[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z=\frac{80-77}{3.5} \\\\ Z=0.85[/tex]
Hence,the Z-score for Tiffany's exam grade will be 0.85.

Use the distance formula to calculate XY, then equate to 10
d = [tex]\sqrt{x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = X(a -5, - 2a) and (x₂, y₂ ) = Y(a + 1, 2a)
XY = [tex]\sqrt{(a +1-(a-5))^2+(2a-(2a))^2\\}[/tex]
= [tex]\sqrt{(a+1-a+5)^2+(4a)^2}[/tex]
= [tex]\sqrt{6^2+16a^2}[/tex] , then
[tex]\sqrt{36+16a^2}[/tex] = 10 ( square both sides )
36 + 16a² = 100 ( subtract 36 from both sides )
16a² = 64 ( divide both sides by 16 )
a² = 4 ( take the square root of both sides )
a = ± [tex]\sqrt{4}[/tex] = ± 2

She will have 43 puzzle books in 5 years.
Rate of change per year____
Initial value____
Help me please :))) <3 ~
Answer:
7
8
Step-by-step explanation:
The rate of change per year is the number of books she gets each year.
The problem states "She will buy 7 new puzzle of books each year."
The rate of change per year is 7.
The initial value is the beginning value.
She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.
She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.
43 - 35 = 8
She started with 8 books.
The initial value is 8.

258 cm PLZ GIVE ME BRAINLIEST
Step-by-step explanation:
Since the chord is given as 80cm, we know from the definition of a chord that it is equidistant to both sides of the circle. Therefore, half the chord is 40. The extension of the center to the chord is perpendicular to the chord(definition of a chord). Therefore, if we connect the center of the circle to the edge of the chord, it's a right triangle. Also the center of the chord is the radius of the circle. Pytharogean theorem: 40^2 + 9^2=r^2 : 1681=r^2: r=41. The radius is 41. Curcumference of circle: pi*2*r : pi*2*41 : pi*82= 258 cm.
