33.33 lb of 90% cocoa cholcolate should be mixed.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: A baker has to mix 70% cocoa with 90% cocoa and he has 100 lb of the first chocolate.
let x lb of chocolate be mixed with 100 lb to give the 75 % chocolate variety
Thus, x×90%+100×70% / 90%+70% = 75%
0.9x+70 /x+100=0.75
0.9x+70=0.75x+75
0.15x=5
x=33.33
Thus 33.33 lbs of 90% cocoa should be mixed to get 75% cocoa
Hence, 33.33 lb of 90% cocoa cholcolate should be mixed.

Find the equation of the line
Answer:
y = 2x - 7
Step-by-step explanation:
The question is asking for slope-intercept form, y = mx + a.
Given:
(1, -5) and (9, 11)
Find the slope (m) between the two points:
m = (y2 - y1) / (x2 - x1)
x1 = 1
x2 = 9
y1 = -5
y2 = 11
m = ( 11 - (-5) )/(9 - 1)
= 16/8
m = 2
y = 2x + a
Use one of the two points to find a (I will use (1, -5)):
-5 = 2(1) + a
-5 = 2 + a
-7 = a
a = -7
y = 2x + (-7)
y = 2x - 7
PLEASE HURRY THE TEST HAS 5 MINS LEFT I NEED HELP WITH QUESTION 5 ASAP
Answer:
5.83
Step-by-step explanation:
i used pythagorean theorem
side a is 5 because congruence
side b would be 3 because 9 - 6 = 3
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
sqrt of 34 is 5.83
the sum of a number and 7 is less than 12

use the subsitution method to slove the system of equations.Choose the correct ordered pair. x+3y=9 y=x-5
Answer:
(6, 1)
Step-by-step explanation:
We are given the equation for (y), [y=x-5]
So we can implement that in all the places the (y) are in the other equation.
x+3(x-5)=9
x+3x-15=9
add 15 to each side
4x=24
Divide each side by 4
x=6
Now we can apply our (x) into one of the equations.
y=(6)-5
y=1
So our solution is (6, 1)

I need the slope and the y - intercept in the equation. I’ll give you a if you help me
Answer:
m = slope = 1/2The y-intercept = (0, 5) The equation of the line is:[tex]y=\frac{1}{2}x+5[/tex]
Step-by-step explanation:
Considering the line graph
Some of the points on the line are given by
(0, 5)(2, 6)(4, 7)(6, 8)Finding the slop between any two given points
Let us take the point (0, 5) and (2, 6)
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)[/tex]
[tex]m=\frac{6-5}{2-0}[/tex]
[tex]m=\frac{1}{2}[/tex]To the y-intercept, set x = 0.
We already know that when x = 0, the value of y = 5
so
The y-intercept = (0, 5)Equation of line can be obtained using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 1/2 and any point let say (2, 6)
[tex]y-6=\frac{1}{2}\left(x-2\right)[/tex]
add 6 to both sides
[tex]y-6+6=\frac{1}{2}\left(x-2\right)+6[/tex]
[tex]y=\frac{1}{2}x+5[/tex]
Therefore, the equation of the line is:
[tex]y=\frac{1}{2}x+5[/tex]Original amount: 1299 new amount: 499 what is the percent change?

The perimeter of a rectangular parking lot is 292 m.
If the length of the parking lot is 81 m, what is its width?
Answer:
the answer would be 211
Step-by-step explanation:
you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.
292-81= 211
Answer:
68m
Step-by-step explanation:
The perimeter of a rectangle with length and width is given by the following.
P=21+2w
We need to find w when P=292 m and l+78m .
Using these values in the equation above, we'll solve for w.
P=21+2w
292=2(78)+2w
292=156+2w
136=2w
68=w
Subtracting 156 from both sides
Dividing both sides by 2
So the width of the parking lot is 68m
Sam and Sara bought the same number of pencils. Sam put ¼ of his pencils in his pencil box and Sara put ½ of her pencils in her pencil box. If sam had put 5 in his box then how many pencils did sara put in her pencil box?
Answer:
10 pencils
Step-by-step explanation:
Given that:
Number of pencils bought by Sam and Sara are the same.
Let the number of pencils bought = x
Sam put 1/4 in his pencil box
Sara put 1/2 in her pencil box
1/4 of Sam's pencil = 5
That is ;
1/4 of x = 5
x /4 = 5
x = 20
Hence, number of pencils Sara put in her box
:
1/2 of 20
1/2 * 20
20/2
= 10
10 pencils

Which is an equivalent equation solved for LaTeX: yy? Group of answer choices LaTeX: y=a-\pi x y = a − π x LaTeX: y=a\ast \pi x y = a ∗ π x LaTeX: y=a\div (\pi x) y = a ÷ ( π x ) LaTeX: y=a+(\pi x)
Answer LaTeX: y=a\div (\pi x)y = a ÷ ( π x )
Question:
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?
Answer:
[tex]y = \frac{a}{\pi x}[/tex]
Step-by-step explanation:
Given
[tex]a = \pi xy[/tex]
Required
Solve for y
The question implies that, we make y the subject of formula:
This is done as follows:
[tex]a = \pi xy[/tex]
Divide through by [tex]\pi x[/tex]
[tex]\frac{a}{\pi x} = \frac{\pi xy}{\pi x}[/tex]
Isolate y on the right hand side
[tex]\frac{a}{\pi x} = y[/tex]
Reorder
[tex]y = \frac{a}{\pi x}[/tex]
Hence, the solution to the question is: [tex]y = \frac{a}{\pi x}[/tex]
