Step-by-step explanation:
Gary saved dimes and nickels at a ratio of 5:7.
5/12 = Dimes
7/12 = Nickels
Then, he saved 20% more dimes and 3 times the number of nickels.
If he had 540 dimes and nickels altogether in the end, how many more nickels then dimes did he have?
Let the number of dimes = x
Let the number of nickels = y
Total number of dimes and nickels = 540

Answer:
3.44 rounded to the nearest whole number is 3
In one study, researchers at a clinic looked at more than 120,000 patients enrolled in 14 international studies in the past 10 years. Among the patients with heart problems, researchers found at least one risk factor in 84.7% of the women and 80.7% of the men. If a woman is selected at random from the women with heart problems, what is the probability she has none of the risk factors? Write your answer as a percentage. % If a man is selected at random from the men with heart problems, what is the probability he has none of the risk factors? Write your answer as a percentage. %
Answer:
The probability she has none of the risk factors [tex]P(N) = 15.3 \%[/tex]
The probability he has none of the risk factors [tex]P(M) = 19.3 \%[/tex]
Step-by-step explanation:
From the question we are told that
The number of patients enrolled is n = 120,000
The number of international studies is N = 14
The number of years is y = 10 years
The risk factor for women is r = 84.7%
The risk factor for men is R = 80.7%
Generally the probability that she has none of the risk factors is mathematically represented as
[tex]P(N) = 100 - r)\%[/tex]
=> [tex]P(N) = 100 - 84.7)\%[/tex]
=> [tex]P(N) = 15.3 \%[/tex]
Generally the probability that he has none of the risk factors is mathematically represented as
[tex]P(M) = 100 - R)\%[/tex]
=> [tex]P(M) = 100 - 80.7)\%[/tex]
=> [tex]P(M) = 19.3 \%[/tex]

Answer: [tex]a)\quad y=\dfrac{4}{5}x+\dfrac{8}{5}[/tex] [tex]b)\quad y=\dfrac{1}{3}x+\dfrac{10}{3}[/tex]
Step-by-step explanation:
Use the Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
and the Point-Slope formula: y - y₁ = m(x - x₁)
a) (-2, 0) and (3, 4)

Let (x₁, y₁) = (-2, 0)
y - y₁ = m(x - x₁)
[tex]y-0=\dfrac{4}{5}\bigg(x-(-2)\bigg)\\\\\\y\quad =\dfrac{4}{5}\bigg(x+2\bigg)\\\\\\\large\boxed{y\quad =\dfrac{4}{5}x+\dfrac{8}{5}}[/tex]
b) m = 1/3 (x₁, y₁) = (2, 4)

f(x)=-2x+13 for f(-4) Evaluate
Answer:
f( - 4) = 21Step-by-step explanation:
[tex]f(x)=-2x+13[/tex]
To find f(-4), substitute the value of x that's - 4 into f(x). That is for every x in f(x) replace it with - 4
We have
[tex]f( - 4) = - 2( - 4) + 13 \\ = 8 + 13 \\ = 21 \: \: \: \: \: \: \: \: [/tex]
We have the final answer as

Angelica earns d dollars for babysitting each week. She also receives an allowance of $10 per week. The expression (10+d)∙5 can be used to calculate the amount of money she will have at the end of 5 weeks. What is the amount of money Angelica will have at the end of five weeks if d = $25?
Answer:
The amount of money Angelica will have at the end of five weeks if d = $25 is $175.
Step-by-step explanation:
The given information are;
The allowance Angelica earns for baby sitting = d dollars per week
The amount she receives as allowance = $10 per week
The amount she will have at the end of 5 weeks = (10 + d)·5
The amount, A, of money Angelica will have at the end of five weeks if d = $25 is given as follows;
A = (10 + 25) × 5 = $175
The amount of money Angelica will have at the end of five weeks if d = $25 is $175.

10 – 2(3x – 1) > 6x + 10
Pls solve with steps and explain
Answer:
x < 1/6
Step-by-step explanation:
In the equation 10 – 2(3x – 1) > 6x + 10, start by using the distributive property. Once you've done that, you'd now get 10-6x+2 > 6x+10.
Now, add 10 and 2 togther to get -6x+12 > 6x+10.
Subtract 6x to both sides and subtract 12 to both sides and now you'll get
-12x > -2.
Now, divide each side by -12 to get x < 2/12 or 1/6. Notice how the sign is flipped since you divided by a -.
-4y+20=-x solve for y
Answer:
y = x/4 + 5
Step-by-step explanation:
Solve for y:
20 - 4 y = -x
Hint: | Isolate terms with y to the left-hand side.
Subtract 20 from both sides:
-4 y = -x - 20
Hint: | Solve for y.
Divide both sides by -4:
Answer: y = x/4 + 5
Answer:
y=1/4x+5

Seyna can eat 1/4 of a pizza in 1/3 of an hour. At this rate, what fraction of a pizza could she eat in one hour?
If she can eat 1/4 of a pizza in 1/3 hours, multiply 1/3 by 3 to get 3/3 hours and do he same with 1/4, that gets you 3/4 of a pizza in 1 hour.
Seyna can eat 3/4 of a pizza in one hour.
Given that Seyna can eat 1/4 of a pizza in 1/3 of an hour.
We need to find that at this rate what fraction of a pizza could she eat in one hour.
To find out the fraction of a pizza Seyna can eat in one hour, we need to determine how many fractions of 1/4 pizzas she can consume in 1 hour.
We know that Seyna can eat 1/4 of a pizza in 1/3 of an hour. Let's calculate how many 1/4 pizzas she can consume in 1 hour by multiplying the given rate by 3:
(1/4) x (3/1) = 3/4
Therefore, Seyna can eat 3/4 of a pizza in one hour.
