Melissa earns
as much in a day of babysitting as Bret does, and Breanna earns $20 more than Bret. If their total babysitting
earnings for one day is $245, how much does Melissa earn per day?
Answer:
$75
Step-by-step explanation:
let the amount melissa earn be X
and we know that Bret also earns X
than
Breanna earns = X+20
so
X+X+X+20 = 245
3X +20=245
3X= 245-20
3X= 225
X= 75
Read the problem. Tamir baked cookies for his mother's birthday. He mixed the cookie batter, scooped it into mounds on a cookie sheet, and then put the cookie sheet in the oven. After 20 minutes in the oven, 15 of the 20 cookies were fully baked. Shade the grid to show the fraction of the cookies that were fully baked after 20 minutes in the oven. What percent of the cookies were fully baked? You can use your model to help.
Answer:
Percentage baked= 75%
Step-by-step explanation:
Giving the following information:
After 20 minutes in the oven, 15 of the 20 cookies were fully baked.
First, the fraction of cookies baked:
Fraction of cookies= 15/20= 3/4
Now, to calculate the percentage, we need to use the following formula:
Percentage baked= (15/20)*100
Percentage baked= 75%

Answer:
what is the question and where is it?
Step-by-step explanation:
What is the distance between the
two points
(7.8)
{3,2)
To find the exact difference, we have to subtract the two decimal points.
1. First, we'll subtract the whole number. Then, we'll subtract the decimal number. This will make mental math easier.
a. 7 - 3 = 4
b. 8 - 2 = 6
2. Add the answers together to get your final answer.
a. = 4.6
The exact distance between the two points is 4.6. If you can't figure this strategy out, do algorithm. The simplist way to solve this is to use a calculator, which I checked my answer on. Have a nice day! :)

X-intercept:
Answer:
x=-1/2y , +3/4b, 7/4 this is the answer
The y-intercept is (0, 5) and the x-intercept is (2.5, 0).
What is an intercept of the straight line?In the context of a straight line in a two-dimensional plane, an intercept refers to the point(s) where the line intersects with one or both of the coordinate axes (i.e., the x-axis and the y-axis).
To find the y-intercept, we set x = 0 and solve for y:
-4(0) + 7 = 2y - 3
7 = 2y - 3
2y = 10
y = 5
Therefore, the y-intercept is (0, 5).
To find the x-intercept, we set y = 0 and solve for x:
-4x + 7 = 2(0) - 3
-4x + 7 = -3
-4x = -10
x = 2.5
Therefore, the x-intercept is (2.5, 0).

Complete question :
A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.
Construct a confidence interval for the mean jump height of gray kangaroos.
Answer:
(271, 301)
Step-by-step explanation:
Given that:
Mean (x¯) = 286
Margin of Error = 15 inches
The confidence interval :
(Mean - Margin of Error), (mean + margin of error)
(286 - 15), (286 + 15)
(271, 301)
Hence confidence interval equals : (271, 301)

Find the perimeter of the figure below, composed of a rectangle and semicircle. Round to the nearest tenths place.
The perimeter of the given figure is 44.28 units.
Given that, from the figure length of a rectangle = 15 units, width of a rectangle = 4 units and the radius of a semicircle = 2 units.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Here, perimeter = Perimeter of a rectangle + Circumference of a semicircle
= 2(15+4) + 2πr/2
= 2×19 + 3.14×2
= 38 + 6.28
= 44.28 units
Therefore, the perimeter of the given figure is 44.28 units.

Find a polynomial of lowest degree that has the indicated zeroes: 1+i, 1-i, 3
Answer:
-3i + (6 x 9)
Step-by-step explanation:
The zeroes of the polynomial are 1 + i, 1 – i, and 3. Then the polynomial of the lowest degree will be x³ – 5x² + 8x – 6.
What is polynomial?A polynomial expression is an algebraic expression with variables and coefficients.
The zeroes of the polynomial will be 1 + i, 1 – i, and 3.
Then the factor of the polynomial will be (x – 1 – i), (x – 1 + i), and (x – 3).
Then the polynomial will be
(x – 1 – i)(x – 1 + i)(x – 3)
[(x – 1)² – i²](x – 3)
(x² – 2x + 2)(x – 3)
x³ – 2x² – 3x² + 2x + 6x – 6
