Answer:
2750
Step-by-step explanation:
Remark
You have to assume that this can be solved by using a proportion. A proportion is 2 equal ratios. Three parts of the 2 ratios must be known and your job is to find the 4th one.
Equation
w*L/C1 = w1*L1 / x
Solution
w = 8
L = 10
w1 = 20
L1 = 25
C1 = 449
C2= x
Solution
8*10/440 = 20*25/x Combine
80/440 = 500 / x Cross Multiply
80x = 440*500 Combine
80x = 220000 Divide by 80
x = 220000/80
Answer

A science test, which is worth 100 points, consists of 24 questions. E
points. If x is the number of 3-point questions and y is the number of
represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions
The test contains 4 three-point questions and 20 five-point ques
The test contains 10 three-point questions and 14 five-point que
The test contains 14 three-point questions and 10 five-point qu-
O The test contains 20 three-point questions and 8 five-point que
Answer:
B
Step-by-step explanation:
actually the question is about to solve x and y
x + y = 24, x = 24 - y, put into the other equation
3x + 5y = 100
3(24 - y) + 5y = 100
72 - 3y + 5y = 100
2y = 28
y = 14
x = 24 - 14 = 10
no. of 3 point question = 10, no. of 5 point question = 14

the volume of Cone A is 48 ft², find the volume b of Cone b
Check the picture below.
[tex]\cfrac{\stackrel{A~radius}{(12)^3}}{\underset{B~radius}{(30)^3}}~~ = ~~\cfrac{\stackrel{A~volume}{48}}{\underset{B~volume}{V}}\implies \cfrac{1728}{27000}~~ = ~~\cfrac{48}{V}\implies \cfrac{8}{125}~~ = ~~\cfrac{48}{V} \\\\\\ 8V=(48)(125)\implies V=\cfrac{(48)(25)}{8} \\\\\\ V=\cfrac{48}{8}25\implies V=6(25)\implies V=150[/tex]
For a scientific experiment, a physicist must make sure that the temperature of a metal does not get colder than −120°C or the metal will not be usable. The physicist changes the metal's temperature at a steady rate of −6°C per hour.

If y=2x-8 what is the minimum value of the product xy
The minimum value of the product is -8.
What is the minimum value?The minimum value is the y value of the lowest point on the graph.
The function y = 2x-8 and we have to find the minimum value of the XY.
Plugging the value of y in the product;
[tex]\rm f(x)=x(2x-8)\\\\f(x)=2x^2-8x[/tex]
f(x) represents an upward parabola and we know that for an upward parabola, the minimum point is the vertex.
So in order to find the minimum value, we find the y coordinate of the vertex of the parabola.
The x-coordinate of the parabola is given by;
[tex]\rm = \dfrac{-b}{2a}\\\\=\dfrac{-8}{2\times 2}\\\\ =\dfrac{-8}{4}\\\\=-2[/tex]
The y -coordinate of the parabola is;
[tex]\rm f(x)=2x^2-8x\\\\f(2)=2(2)^2-8(2)\\\\f(2)=2\times 4-16\\\\ f(2)=8-16\\\\ f(2)=-8[/tex]
The vertex is (2,-8)
Hence, the minimum value of the product is -8.

What is the probability that the average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds?
The probability that the average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds is 0.74.
What is the probability?Probability is the branch of mathematics, which discusses the occurrence of a random experiment.
The average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds.
The standard error of the sample will be:
[tex]\rm Standard \ error=\dfrac{Standard deviation}{\sqrt{ Number \ of \ babies} }\\\\\rm Standard \ error=\dfrac{1.2}{\sqrt{ 4} }\\\\Standard \ error=\dfrac{1.2}{2}\\\\Standard \ error=0.6[/tex]
The probability that the average of four babies P(4 babies will be between 8.4 - 9.6 pounds) is;
[tex]\rm P(6.8\leq X\leq 9.2)= \left( \dfrac{6.8-8}{0.6}\leq X\leq \dfrac{9.2-8}{0.6} \right )\\\\\rm P(6.8\leq X\leq 9.2)= \left( \dfrac{-1.2}{0.6}\leq X\leq \dfrac{1.2}{0.6} \right )\\\\\rm P(6.8\leq X\leq 9.2)= \left( -2\leq X\leq 2 \right )\\\\\rm P(6.8\leq X\leq 9.2)= P(Z\leq -2)-P(Z\leq 2)\\\\ P(6.8\leq X\leq 9.2)=0.97-0.22\\\\ P(6.8\leq X\leq 9.2)=0.74[/tex]

gallons each day. After 3 days, she has 213 gallons of gas left in her gas
tank. Write an equation to represent the number of gavons of gas g in her
tank after d days. Then, find the amount of gas in her tank after 8 days.
linear application
The amount of gas in her tank after 8 days given the linear equation g = 213 - 1.6d is 200.2 gallons of gas
Linear equationGallons of gas used per day = 1.6 gallonsNumber of days = dQuantity of gas = gThe equation
g = 213 - 1.6d
Gas remaining after 8 days
g = 213 - 1.6(8)

Answer:

Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 , ∠ 5 , ∠ 6 are exterior angles of the triangle
-------------------------------------------
(14)
∠ 1 and ∠ 4 are adjacent angles and sum to 180° , then
∠ 1 = 180° - 58° = 122°
∠ 2 + ∠ 3 = ∠ 4
∠ 2 + 32° = 58° ( subtract 32° from both sides )
∠ 2 = 26°
∠ 5 = ∠ 1 + ∠ 3 = 122° + 32° = 154°
∠ 6 = ∠ 1 + ∠ 2 = 122° + 26° = 148°
(15)
∠ 4 = ∠ 2 + ∠ 3 = 11° + 143° = 154°
∠ 1 = 180° - ∠ 4 = 180° - 154° = 26°
∠ 5 = ∠ 1 + ∠ 3 = 26° + 143° = 169°
∠ 6 = ∠ 1 + ∠ 2 = 26° + 11° = 37°

Answer:
35 -10√10 + 14√6 - 8√15Step-by-step explanation:
(√2 + √3)² · (√5 - √2)²
use (a ± b)² = a² ± 2ab + b²
= [(√2)² + 2(√2)(√3) + (√3)²] · [(√5)² - 2(√5)(√2) + (√2)²]
= (2 + 2√6 + 3) · (5 - 2√10 + 2)
= (5 + 2√6)(7 - 2√10)
use FOIL: (a + b)(c + d) = ac + ad + bc + bd
= (5)(7) + (5)(-2√10) + (2√6)(7) + (2√6)(-2√10)
= 35 - 10√10 + 14√6 - 4√60
= 35 - 10√10 + 14√6 - 4√(4 · 15)
= 35 - 10√10 + 14√6 - 4 · √4 · √15
= 35 -10√10 + 14√6 - 4 · 2 · √15
= 35 -10√10 + 14√6 - 8√15
