Answer:
300 masks
Step-by-step explanation:
If 267 is 89% of the whole amount, we can set up the following proportion:
[tex]\frac{89}{100} =\frac{267}{x}[/tex], where x is the total amount of masks we need to find.
If we cross-multiply, we get 26700=89x. Divide both sides by 89, and we get 300. So, Cameron has a total of 300 masks in his collection.
I hope this helped.
Answer:
300 masks
Step-by-step explanation:
89% = 0.89
( / ) = divided by
267/total amount of masks = 0.89
267/0.89 = 300
300 masks in total
y varies jointly as x and z. y = 75 when x = 5 and z = 5. Find y when x = 4 and z=6. y =
Answer:
y = 72
Step-by-step explanation:
Joint proportion is given by the expression;
y = kxz
Given the following values;
y = 75, x = 5 and z = 5
To find the constant, k;
75 = k*5*5
75 = 25k
k = 75/25
k = 3
Next, we find the value of y when x = 4 and z= 6
y = kxz
y = 3*4*6
y = 72
Solve for c.
a = 11 + 4b – 4c
Answer:
c would be equal to 2948. hope that helps
Answer:
[tex]c=b-\frac{a}{4} +\frac{11}{4}[/tex]
Step-by-step explanation:
[tex]a=11+4b-4c \\a-11=4b-4c\\a-11-4b=-4c\\-\frac{a}{4} +\frac{11}{4} +b=c[/tex]
Rearranging the terms to make it look cleaner, we get:
[tex]c=b-\frac{a}{4} +\frac{11}{4}[/tex]
6y-5=7 two step equations
Answer:
The answer is y = 2.
Step-by-step explanation:
1) Add 5 to both sides.
[tex]6y = 7 + 5[/tex]
2) Simplify 7 + 5 to 12.
[tex]6y = 12[/tex]
3) Divide both sides by 6.
[tex]y = \frac{12}{6} [/tex]
4) Simplify 12/6 to 2.
[tex]y = 2[/tex]
Thus, the answer is y = 2.
The value of y in 6y-5=7 is 2.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
6y-5=7
Now, solving for y
Add 5 both side
6y-5 + 5=7 +5
6y= 12
Now, divide both side by 6
6y/6 = 12/6
y= 2
Hence, the value of y is 2.

Given f(x) = 3x^3 - 4x + k, and x – 1 is a factor of f(x), then
what is the value of k?
Answer:
The value of k is 1.
Step-by-step explanation:
x – 1 is a factor of f(x)
This means that:
x - 1 = 0
x = 1
That means that when [tex]x = 1, y = 0[/tex]. We use this to find the value of k.
f(x) = 3x^3 - 4x + k
[tex]3*1^3 - 4(1) + k = 0[/tex]
[tex]3 - 4 + k = 0[/tex]
[tex]k = 1[/tex]
The value of k is 1.

Find the midpoint of AB for: A(7,0)|and B(0,3)
Answer:
[tex]\boxed {\boxed {\sf (\frac {7}{2}, \frac{3}{2}) \ or \ (3,5, 1.5) }}[/tex]
Step-by-step explanation:
The midpoint is essentially a point with the average of the 2 x-coordinates and the 2 y-coordinates.
The formula is:
[tex](\frac {x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
We are given two points: A (7,0) and B (0, 3). Remember points are written as (x, y).
Therefore,
[tex]x_1= 7 \\y_1=0 \\x_2=0 \\x_2=3[/tex]
Substitute the values into the formula.
[tex](\frac {7+0}{2}, \frac{0+3}{2})[/tex]
Solve the numerators first.
[tex](\frac {7}{2}, \frac{3}{2})[/tex]
The midpoint can be left like this because the fractions are reduced, but it can be written as decimals too.

Which is an equation of the line that has a slope of 1/2 and passes through the point (3, -1)?
Answer:
y + 1 = (1/2)(x - 3) - point-slope form
OR
y = (1/2)x - 5/2 - slope-intercept form
Step-by-step explanation:
Given a slope and point, use point-slope form to write the equation for the line:
y - y1 = m(x - x1)
(x1, y1) is the point given and m is the slope.
y - (-1) = (1/2)(x - 3)
y + 1 = (1/2)(x - 3)
If you need to rewrite in slope intercept form, you can do so by distributing the 1/2 to the x - 3 and subtracting 1 from both sides:
y + 1 = (1/2)x - 3/2
y = (1/2)x - 5/2
Answer:
[tex]\boxed {\boxed {\sf y= \frac {1}{2}x - \frac {5}{2}}}[/tex]
Step-by-step explanation:
The equation of a line can be found using the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point the line passes through. For this line, the slope is 1/2 and the point is (3, -1). Therefore,
[tex]m= \frac {1}{2} \\x_1= 3 \\y_1= -1[/tex]
Substitute the values into the formula.
[tex]y--1= \frac {1}{2}(x-3)[/tex]
[tex]y+1= \frac {1}{2}(x-3)[/tex]
The equation can be left like this, or put into slope-intercept form (y=mx+b).
First, distribute the 1/2. Multiply each term inside the parentheses by 1/2.
[tex]y+1= \frac {1}{2}x - \frac {3}{2}[/tex]
Next, subtract 1 from both sides of the equation.
[tex]y+1-1= \frac {1}{2}x - \frac {3}{2}-1[/tex]
[tex]y= \frac {1}{2}x - \frac {5}{2}[/tex]

Answer:
There are at least 111 rose blooms in May's Garden.

How many days should it take the remaining 3 workers to build a barn?
9514 1404 393
Answer:
15 days7 workersStep-by-step explanation:
The effort required to complete a task is often estimated in terms of person·days. Amy's barn-building task takes an effort of ...
(5 workers)(9 days) = 45 worker·days
If there are only 3 workers, the time required is ...
time = (45 worker·days)/(3 workers) = 15 days
__
If the barn is to be build in 7 days, the number of workers required is ...
(45 worker·days)/(7 days) = 6 3/7 workers
A minimum of 7 workers are required to build the barn in 7 days or less. (6 workers will take 7 1/2 days, so aren't enough.)
