Mrs. Wood is going to the desert during Thanksgiving
break. If she drives 120 miles in 2 hours, how many
more miles are left if she has to drive for another 5
hours at a proportional rate?
Answer:
she has to drive another 300 miles
Step-by-step explanation:
120/2=60 so 60*5=300
Answer:
300 miles left
Step-by-step explanation:
here's why if she is driving already 2 miles which is 120 and she is going to to drive for 5 hours, 5 hours is 300 miles which that means she has left 300.

A hungry Emperor penguin was swimming 21 feet below sea level. It swam up 9 feet to eat a fish. What is the position of the penguin now relative to sea level?
Answer:
Step-by-step explanation:
21 feet below is written as -21
9 feet up is written as +9
So we have -21 + 9 = -12 or 12 feet below sea level

32.50/2.5=13
You divide them so you get the price per one pound.
Hope this helps!!!!
Answer:
Company B offers the lowest price per pound of 12.72
Step-by-step explanation:
Unit Price
Given a product that costs X dollars and has Y pounds, the unit price is given by X/Y dollars per pound.
Elle is comparing prices to purchase candy online. Company A offers 2 1/2 pounds of chocolate for $32.50 and Company B offers 2 3/4 pounds of chocolate for $35.00.
The offer of Company A is for 2 1/2 pounds = 2.5 pounds
The offer of Company B is for 2 3/4 pounds = 2.75 pounds
The unit price for Company A is $32,50/2.5 = $13/pound
The unit price for Company B is $35,00/2.75 = $12.72/pound
Company B offers the lowest price per pound of 12.72

3x -20y = -81
The answer can be anything thing that occurs during solving the problem or is the answer.
Answer:
The 1st, 2nd and 5th options are correct.
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
①Rewrite the given equation into the form of y=mx+c to find the gradient.
[tex]- \frac{5}{3} x = \frac{1}{4} y - 8 \\ \frac{1}{4} y = - \frac{5}{3} x + 8 \\ y = - \frac{20}{3} x + 32[/tex]
Thus, the gradient of the given equation is [tex] - \frac{20}{3} [/tex].
② Find gradient of unknown line.
The product of the gradients of perpendicular lines is -1.
Let m be the gradient of the unknown line.
[tex]- \frac{20}{3} m = - 1 \\ m = - 1 \div ( - \frac{20}{3} ) \\ m = - 1 \times ( - \frac{3}{20} ) \\ m = \frac{3}{20} [/tex]
③Substitute the value of m into the equation.
[tex]y = \frac{3}{20} x + c[/tex]
④ Find the value of c by substituting a pair of coordinates.
When x= -7, y= 3,
[tex]3 = \frac{3}{20} ( - 7) + c \\ 3 = - \frac{21}{20} + c \\ c = 3 + \frac{21}{20} \\ c = 4 \frac{1}{20}[/tex]
Thus, the equation of the line is [tex]y = \frac{3}{20} x + 4 \frac{1}{20} [/tex].
Thus, the 4th option is incorrect.
Writing c as an improper fraction,
[tex]y = \frac{3}{20}x + \frac{81}{20} [/tex]
Thus, the 1st option is correct.
-3 from both sides of the equation:
[tex]y - 3 = \frac{3}{20} x + \frac{21}{20} [/tex]
Factorise 3/20 out of the right hand side:
[tex]y - 3 = \frac{3}{20} (x + 7)[/tex]
Thus, the 2nd option is correct.
The 3rd option is incorrect as factorising -20/3 out would leave us with -0.0225 as the coefficient of x.
Let's look at the 5th option.
[tex]y = \frac{3}{20} x + 4 \frac{1}{20} [/tex]
×20 on both sides:
[tex]20y = 3x + 81[/tex]
-20y on both sides:
[tex]3x - 20y + 81 = 0[/tex]
-81 on both sides:
[tex]3x - 20y = - 81[/tex]
Thus, the 5th option is also correct.
A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?
y = –4/3x
y = –3/4x
y = 3/4x
y =4/3 x
Answer:
[tex]y=\frac{3}{4}x[/tex]
Step-by-step explanation:
If it is a direct variation function, then [tex]\frac{y}{x}=k[/tex].
[tex]k[/tex] can be found by choosing a point and doing [tex]y[/tex] divided by [tex]x[/tex].
So we can find [tex]k[/tex] by doing -6 divided by -8 or 9 divided by 12.
Both of these values are equal to 0.75 or 3/4 as a fraction.
So you can say any point in this relation will follow the equation:
[tex]\frac{y}{x}=\frac{3}{4}[/tex]
Multiply both sides by [tex]x[/tex]:
[tex]y=\frac{3}{4}x[/tex]

Answer:
D) (8,-22)
Step-by-step explanation:
I used my graphing calculator.
Answer:
D
Step-by-step explanation:
A. 9
B. 9 square root of 2
C. 18
D. 18 square root of 2
Answer:
B
Step-by-step explanation:
We are given a right triangle with angles 45, 90, and 45
With this type of right triangle, the ratio of the sides are 1:1:square root of 2
We are also given that the hypotenuse is 18
This means that the sides are in the ratio of x:x:x(square root of 2)
Since 18 is the hypotenuse, we can form the equation of-
18 = x(square root of 2)
18/(square root of 2)=x
x= 9 square root of 2
since y=x, y= 9 square root of 2

William can eat 3 slices of pizza in 5 minutes. If he continues to eat at the same rate, how long will it take him to eat the whole pizza, which has 12 slices of pizza? How many slices can he eat in half of an hour?
Answer:
It will take 20 minutes to finish the whole pizza, and in half an hour he will be able to finish 18 slices
Answer:
William can eat 18 slices of pizza in half of an hour.
William can eat a whole box of pizza in 20 minutes.
Step-by-step explanation:
30 minutes in half of an hour, 30/5 is 6.
3 slices in 5 mins
3 times 6 is 18.

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT
Answer:
The inner surface area is: 1923.25 cm²
Step-by-step explanation:
A hemispherical bowl is made of brass has an inner diameter of 35 cm.
i.e. d = 35 cm
As the radius is basically half of the diameter.
r = d/2
= 35/2
= 17.5 cm
The inner surface area of a hemispherical bowl = 2πr²
= 2(3.14)(17.5)²
=1923.25 cm²
Therefore, the inner surface area is: 1923.25 cm²
which of the following is NOT a root of x (x+3)(x-1)(2x+1)= 0
i. 0
ii. -3
iii. -1
iv. 1/2
A. i only B. iv only
C. i and ii only
D. iii and iv only
Answer:
The answer is A only i. (0)
Answer:
D
Step-by-step explanation:
Given
x(x + 3)(x - 1)(2x + 1) = 0
Equate each factor to zero and solve for x
x = 0
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]
Thus
x = 0, x = - 3, x = 1, x = - [tex]\frac{1}{2}[/tex] are the roots
Hence
111 x = - 1 and iv x = [tex]\frac{1}{2}[/tex] are NOT roots → D
The area of a circle is 25pie in.2. What is it’s radius?
The area of a circle is PI x r^2
25PI = PI x r^2
Divide both sides by PI:
25 = r^2
Take the square root of both sides:
Radius = 5 inches.
Answer:
5 is the radius.
Step-by-step explanation:
Since the formula for area in a circle is [tex]\pi r^{2}[/tex], we can substitute 25 for r squared.
Since 25 is equal to r squared, it means that r is equal to 5.
5 is the radius.
