A scientist had 1.25 ounces of a chemical. He bought 2.5 ounces more of the chemical and then used 0.75 ounce in an experiment. How much chemical does the scientist have remaining?
Answer:
3 ouncesStep-by-step explanation:
Step one:
given data
the initial amount of chemical = 1.25 ounces
Extra amount of chemical =2.5 ounces
Total amount of chemical =1.25+2.5=3.75 ounces
Step two:
we are told that the scientist used 0.75 ounces of chemical
Hence the remaining chemical is
remaining= 3.75-0.75
remaining= 3 ounces
The remainder is 3 ounces
Two girls, Sienna and Lexi, are walking laps on a path that goes around the pond at a local park. They start at the same place on the path, and at the same time. They plan to
continue to walk laps until they are both at the starting point at the same time. Sienna can complete a lap around the pond every 4 minutes. Lexi can complete a lap every 6
minutes.
If both Sienna and Lexi keep walking at these rates, they will first be at the starting point at the same time after
minutes.
When they meet at the starting point, Sienna will have completed
B laps around the pond, and Lexi will have completed
laps.
Answer:
Sienna will have done 6 laps while Lexi would have done 6

Choose the linear equation written in slope intercept
form that matches each graph
Answer:B
Step-by-step explanation:the line touches the graph on the y axis at 3 so the y intercept has to be a positive 3. Then it goes up 1 over 3 each time. Meaning it’s Y=1/3X+3
The area of a circle, in terms of π, is 196π m2.
Find the value of the radius.
Step-by-step explanation:
if area of circle = pi times radius^2,
area of circle divided by pi = radius^2
so, square root (area of circle divided by 2) = radius.
so, 196pi = m2
approx 616
616=m2
sqrt 616 =m
approx value of radius is 25 or 24.8

Which is an equation of the line with slope 1/2 that contains (–4, 7)?
Answer:
y=(-1/2)x-1
Step-by-step explanation:
hope it helps and plz give me Brainliest plz
Equation of line is y = 1/2x + 9 which passes through the point (-4, 7) and has slope 1/2.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have to given that;
Point on the line = (-4, 7).
And, The slope of the line = 1/2
Since, The equation of line passes through the point (- 4, 7).
and, Slope of the line is,
⇒ m = 1/2
Hence, The equation of line is,
⇒ y - 7 = 1/2 (x - (-4))
⇒ y - 7 = 1/2 (x + 4)
⇒ y - 7 = 1/2x + 2
⇒ y = 1/2x + 2 + 7
⇒ y = 1/2x + 9

The cost of catering a dinner is $11.95 per person plus $25 for delivery and setup. Which statement is true about the graph of the function that represents the average cost per person?
The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
The vertical asymptote x = 0 represents that the cost per person approaches $0 as the number of people increases.
The vertical asymptote x = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
B.) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
Good luck with the test! :)
The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
What are asymptotes?"An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity."
"The curves visit these asymptotes but never overtake them. The method opted to find the horizontal asymptote changes involves comparing the degrees of the polynomials in the numerator and denominator of the function. If both the polynomials have the same degree, divide the coefficients of the largest degree terms."
From the equation, y = 11.95x + 25
And from the given graph it is clear that the horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
Hence, A is the correct option.

Guys I need help I’m gonna fail math
Answer:
125% correct
3/5 correct
2/3 correct
Step-by-step explanation:
Here, we want to pick the appropriate conversion from percentage to fraction:
To convert from percentage to fraction, we simply divide by 100
125% = 125/100 = 1.25 correct
30% = 30/100 = 0.3 not 0.03 wrong
1% = 1/100 = 0.01 not 0.001 wrong
60% = 60/100 = 3/5 correct
50% = 50/100 = 1/2 not 1/4 wrong
2/3 = 2/3 * 100 = 200/3 = 66.66667% correct

Every 12th customer gets a free beverage.
Every 15th customer gets a free fish of yogurt.
To find:
The first customer to receive all the three items.
Solution:
Here, we need to find nothing but the Least Common Multiple of the given three numbers 8, 12 and 15 to find the first person who will get all three free items.
Let us use factors of each number:
[tex]8 = 2\times 2\times 2\\12 = 2\times 2\times 3\\15 = 3\times 5[/tex]
The LCM will be:
[tex]2\times 2\times 2 \times 3 \times 5 = \bold{120}[/tex]
Therefore, the answer is:
120th customer will be the first one get all the three items.

What is the measure of angle y?
Answer:
y =50°
Step-by-step explanation:
40°+90°+y = 180° {the sum of angle of triangle is 180°}
or, 130°+ y = 180°
or, y = 180°-130°
or, y =50°
The value of the measure of an angle y in a triangle would be 50 degrees.
Used the concept of angle in a triangle that states,
The sum of all three interior angles in a triangle gives 180 degrees.
Given that,
A triangle is shown in the attached figure.
Here, the triangle shown in the image is a right-angle triangle.
Hence, a measure of an angle = 90 degree
And, the second measure of an angle = 40 degree
So, the sum of interior angles in a triangle gives 180 degrees.
Hence,
40° + 90° + y = 180°
Solve for y,
130° + y = 180°
y = 180° - 130°
Therefore, the value of y is,
y = 50 degree
