Answer:
36 people
Step-by-step explanation:
The ratio of women to men working at a grocery store is 4 to 5.
The ratio =
Women : Men
4 : 5
The sum of the proportion is 4 + 5 = 9
There are 16 women working at the store .
Let us represent the total number of people working at a grocery store as x
Hence:
4/9 of x = 16 women
4/9 × x = 16
4x/9 = 16
Cross Multiply
4x = 16 × 9
x = 16 × 9/4
x = 36 people
The total number of people working in the grocery store is 36 people

you have 576 grams of radioactive kind of mercury. if its half-life is 64 hours,how much will be left after 256 hours?
Answer:
36 gramsStep-by-step explanation:
Amount of radioactive material = 576 gramsHalf-life = 64 hoursTime = 256 hoursCycles of reduction:
256/64 = 4Material will be left:
576*(1/2)^4 = 576*1/16 = 36 gramsAnswer:
36 grams
Step-by-step explanation:
We have 576 grams of the mercury like substance.
Half of it's lifespan is 64 hours.
The time is 256 hours.
256 ÷ 64 = 4
Material will be left:

Find the equation of the line with slope =10 and passing through (-6,7). Write your equation in point slope form AND slope intercept forms.
Answer:
The equation of the line in the slope-point form is y - 7 = 10(x + 6)
The equation of the line in the slope-intercept form is y = 10x + 67
Step-by-step explanation:
The slope-point form of the linear equation is y - y1 = m(x - x1), where
m is the slope(x1, y1) are the point lies on the lineThe slope-intercept form of the linear equation is y = m x + b, where
m is the slopeb is the y-intercept∵ The slope of the line is 10
∴ m = 10
∵ The line passes through the point (-6, 7)
∴ x1 = -6 and y = 7
→ Substitute them in the slope-point form above
∵ y - 7 = 10(x - -6)
∵ (-)(-) = (+)
∴ y - 7 = 10(x + 6)
∴ The equation of the line in the slope-point form is y - 7 = 10(x + 6)
→ Substitute m in the slope-intercept form
∵ y = 10x + b
→ To find b substitute x by -6 and y by 7 in the equation
∵ 7 = 10(-6) + b
∴ 7 = -60 + b
→ Add 60 to both sides to find b
∴ 67 = b
→ Substitute the value of b in the equation
∴ y = 10x + 67
∴ The equation of the line in the slope-intercept form is y = 10x + 67

Answer: x=10, y=7.5
Step-by-step explanation:
For this problem, we are given that BD bisects ABC. That means ABD and DBC are equal to each other. We are also given that ABC is 25. With the given information, we can create two equations.
Equation 1: 2x-y=3y-x
Equation 2: 2x-y+3y-x=25
Now, we can solve for x and y.
2x-y+3y-x=25 [combine like terms]
x+2y=25
Let's simplify Equation 1 by solving for a variable.
2x-y=3y-x [add both sides by x]
3x-y=3y [add both sides by y]
3x=4y [divide both sides by 3]
x=4/3y
Now that we have x, we can plug it into any equation to solve for y.
x+2y=25 [plug in x=4/3y]
(4/3y)+2y=25 [combine like terms]
10/3y=25 [multiply both sides by 3/10]
y=15/2
Now we can plug in y=15/2 to solve for x.
x=4/3y [plug in y=15/2]
x=4/3(15/2) [multiply]
x=10
Now, we know that x=10 and y=7.5.

Paula and Sam were working on a project for their math class. They were studying
scientific notation and decided to research texting in the United States for their
presentation. One statistic they found was that there are an average of 13.9
million texts sent each hour. Paula suggested that they use that information
to determine the average number of texts sent per day. What is the average
number of texts sent in the United States per day?
Answer:
333,600,000 ( This could also be written as 333.6 million).
Step-by-step explanation:
Every hour, there are 13.9 million texts. As there are 24 hours in a day, you must do the equation 13,900,000x24. This is 333,600,000, which is your answer. I hope this helps

Tony makes a phone call at a pay phone. The charge is 25 cents for the first four minutes,
and 10 cents for each additional minute. Tony has $2.10 in change in his pocket. Write an
inequality that can be used to find m, the maximum number of minutes that Tony can talk
on the phone. Solve this inequality algebraically to find the maximum number of whole
minutes he can talk on the phone.
Answer:
it would be a max of 22 mins
Step-by-step explanation:
25C=4 mins
10C*10 mins =1$
$1.25
2.10-1.25=.85
10C*8=80C
so
4+10+8=22
Tony can talk for a maximum of 22 minutes on the phone which is determined by the inequality 0.25 + 0.10 (x-4) ≤ 2.10.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
According to the given question, we can write the inequality would be as:
⇒ 0.25 + 0.10 (x-4) ≤ 2.10
x = an integer number of minutes.
Subtraction is required since the first four are covered by the 0.25 price. Because fractional minutes count as a full minute, an integer is required.
⇒ 0.25 + 0.10x -0.40 ≤ 2.10
⇒ -0.15 +0.10 x ≤ 2.10
⇒ 0.10x ≤ 2.25
⇒ x ≤ 2.25 /0.10
⇒ x ≤ 22.5 ≈ 22
Therefore, the maximum number of whole minutes will be 22 minutes.

Angela uses a scanner to make a reduced-size copy of a rectangular
photo that is 6 inches long and 4 inches wide. The length of the
reduced photo is 4 inches. What is its width?
Answer:
[tex]\dfrac{8}{3}\ \text{inches}[/tex] or [tex]2.67\ \text{inches}[/tex]
Step-by-step explanation:
The photo has length 6 inches and width 4 inches.
The ratio of length to breadth is
[tex]\dfrac{l}{w}=\dfrac{6}{4}=\dfrac{3}{2}[/tex]
Now the reduced length of the photo is 4 inches.
Let [tex]x[/tex] be the reduced width of the photo
[tex]\dfrac{3}{2}=\dfrac{4}{x}\\\Rightarrow x=\dfrac{4}{3}\times2\\\Rightarrow x=\dfrac{8}{3}\ \text{inches}=2.67\ \text{inches}[/tex]
The width of the reduced photo is [tex]\dfrac{8}{3}\ \text{inches}[/tex] or [tex]2.67\ \text{inches}[/tex].
Gianna is working two summer jobs, making $12 per hour washing cars and $8 per
hour landscaping. Last week Gianna worked a total of 5 hours and earned a total of
$48. Graphically solve a system of equations in order to determine the number of
hours Gianna worked washing cars last week, x, and the number of hours Gianna
worked landscaping last week, y.
Answer:
x + y = 5
12x + 8y = 48
x = -y + 5
12(-y + 5) + 8y = 48
-12y + 60 + 8y = 48
-4y + 60 = 48
-4y = -12
y = 3
x + 3 = 5
x = 2
12(2) + 8(3) = 48
24 + 24 = 48
x = 2 hours of washing cars
y = 3 hours of landscaping
Hope this helps!!

The value of x and y should be 2 and 3.
Calculation of the value of x and y:
Since Gianna is working two summer jobs, making $12 per hour washing cars and $8 per hour landscaping. Last week Gianna worked a total of 5 hours and earned a total of $48.
So here the equation should be
x + y = 5
12x + 8y = 48
we can write as
x = -y + 5
So,
12(-y + 5) + 8y = 48
-12y + 60 + 8y = 48
-4y + 60 = 48
-4y = -12
y = 3
Now
x + 3 = 5
x = 2
Therefore, The value of x and y should be 2 and 3.
