Cristina keeps track of how many items are sold each week so she can figure
out how much she needs to bake for the next week. Pretzel rolls are her best-
selling bread. Here are the weekly sales of pretzel rolls in March.
Week
Number of Pretzel Rolls Sold
March 1-7
287
March 8-14 304
March 15-21271
March 22-28 316
Rounding to the nearest 10, what is the best estimate of the number of
pretzel rolls sold in March? Enter your answer in the box.
The estimate of the number of pretzel rolls sold in March will be 890.
How to illustrate the information?The following can be deduced based on the information that given:
March 8-14. 304
March 15-21 271
March 22-28. 316
Therefore, it should be noted that 304 to the nearest ten is 300.
271 to the nearest ten will be 270
316 to the nearest ten will be 320
Therefore, the total number sold in March will be:
= 300 + 270 + 320
= 890

Two angles are supplementary. The larger angle is 88∘ more than the smaller angle. Find the measure of the larger angle.
Step-by-step explanation:
Mathematically the statement can be written as
SUPPLEMENTARY Angles add up to 180°
x+y=180°....(1)
let y be the larger angle and x be the smaller angle.
y=x+88°....(2)
plug in the (2) in the first equation
[tex]x + (x + 88) = 180 \\ 2x + 88 = 180 \\ 2x = 180 - 88 \\ 2x = 92 \\ \frac{2x}{2} = \frac{92}{2} \\ x = 46[/tex]
the measure of the larger angle is y=x+88°
[tex]y = 46 + 88 \\ y = 134[/tex]
The bigger angle is equal to 134°

at a recent school event the booster club was selling school flags and t-shirts as a fundraiser each school flag was sold for $2 and each t-shirt sold for $5 they sold a total of 220 items and made a total of $695 how many of each type did they sell
Write a system of linear equations to model this situation
Answer:
The number of school flags sold are 135 and the number of t-shirts sold are 85.
Step-by-step explanation:
It is given that at a recent school event the booster club was selling school flags and t-shirts as a fundraiser each school flag was sold for $2 and each t-shirt sold for $5 they sold a total of 220 items and made a total of $695.
Now, let us analyze these statements one by one;
Each school flag for the fundraiser was sold for dollar = $2
Each t-shirt for the fundraiser was sold for dollar = $5
Further, they sold a total of 220 items including the school flags and t-shirts and made a total of $695.
Now, let us assume that;
The number of school flag for the fundraiser sold are 'x' and
The number of t-shirts for the fundraiser sold are 'y'
So, we can formulate an equation from the given conditions;
=> 2x + 5y = 695
and
=> x + y = 220
Now, on solving both the equations and putting the value of x in another equation we get;
=> x + y = 220
=> x = 220 - y
Furthermore,
=> 2x + 5y = 695
=> 2 (220 - y) + 5y = 695
=> 440 - 2y + 5y = 695
=> 440 + 3y = 695
=> 3y = 695 - 440
=> 3y = 255
=> y = 255/3
=> y = 85
Now, let us put the value of y in one of the equations formed on the given conditions;
=> x = 220 - y
=> x = 220 - 85
=> x = 135
Therefore, the number of school flags sold are 135 and the number of t-shirts sold are 85.

what is the foil method ive seen people use that as a explnation for expressing trynomials for stuff like (3x+1)(2x-1)
Answer:
First, Outer, Inner, Last: Usually referred to as FOIL for simplicity is a rule for expanding polynomials. It is quite straight forward. You can do as follows for any binomial expression multiplied by a secondary binomial as you have provided.
(3x+1)(2x-1).
Step 1 of FOIL is to multiply the first 2 expressions in your binomials.
(3x)(2x) = 6x^2
Step 2 is to multiply the first by the last
(3x)(-1) = -3x
Step 3 is to do the last by the first
(1)(2x) = 2x
Step 4 is to do the last by the last
(-1)(1) = -1
You are left with the following:
6x^2 -3x + 2x -1

Remember, -x and -1x are the same!

Suppose a relationship is proportional and the point (4,10) lies on the graph of the proportional relationship. Name another point, other than (0,0), that lies on the graph of the line. Please help me.
Another point on function assuming it as direct and linear proportion with the independent variable will be (1,5/2).
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let,s suppose the given graph is a direct relationship and linear as well.
Now,
y ∝ x
By removing proportion,
y = kx
Since (4,10) lies on the graph thus it must satisfy the equation.
So,
y = kx
10 =k (4)
k = 10/4 = 5/2
So the equation is y = (5/2)x
Now corresponding to x = 1 ⇒ y = 5/2
So point (1,5/2) lies on the graph.
Hence "Another point on function assuming it as direct and linear proportion with the independent variable will be (1,5/2)".

A diagonal of a rectanglar field is 16.9m. If the ratio of the length to the width is 12:5, find the (a) dimensions, (b) Perimeter of the field
we get that the length of the rectangular field is 15.6 m, width is 56.5 m and the perimeter is 44.2 m.
The diagonal of a rectangular field = 16.9 m
d = 16.9 m
Ratio of length to the width is 12 : 5
Let length be 12 x
Width = 5 x
We get that:
16.9² = (12 x)² + (5 x)²
285.61 = 144 x² + 25 x²
169 x² = 285.61
x² = 285.61 / 169
x² = 1.69
x = √1.69
x = 1.3 m
Length = 12 (1.3 m) = 15.6 m
Width = 5 (1.3 m ) =6.5 m
Perimeter = 2 ( l + w)
P = 2( 15.6 + 6.5)
P = 2(22.1) m
P = 44.2 m
Therefore, we get that the length of the rectangular field is 15.6 m, width is 56.5 m and the perimeter is 44.2 m.

Answer:
square: 9 square unitstriangle: 24 square unitsStep-by-step explanation:
Using a suitable formula the area of a polygon can be computed from the coordinates of its vertices. You want the areas of the given square and triangle.
SquareThe spreadsheet in the first attachment uses a formula for the area based on the given vertices. It computes half the absolute value of the sum of products of the x-coordinate and the difference of y-coordinates of the next and previous points going around the figure.
For this figure, going to that trouble isn't needed, as a graph quickly reveals the figure to be a 3×3 square.
The area of the square is 9 square units.
TriangleThe same formula can be applied to the coordinates of the vertices of a triangle. The spreadsheet in the second attachment calculates the area of the 8×6 triangle.
The area of the triangle is 24 square units.
__
Additional comment
We have called the triangle an "8×6 triangle." The intention here is to note that it has a base of 8 units and a height of 6 units. Its area is half that of a rectangle with the same dimensions. These dimensions are readily observed in the graph of the vertices.

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find m<2.
Answer:
∠ 2 = 122°
Step-by-step explanation:
given ∠ 2 = 2 ∠ 1 + 6
a linear pair of angles sum to 180° , then
∠ 1 + ∠ 2 = 180° , that is
∠ 1 + 2∠ 1 + 6 = 180° ( subtract 6 from both sides )
3∠ 1 = 174° ( divide both sides by 3 )
∠ 1 = 58° , then
∠ 2 = 180° - 58° = 122°
What is 3 5/8 in decimal form?
Answer:
35/8
step 1: turn the mixed fraction to an improper fraction =29/8
step 2: divide 29 by 8 ,it gives you 3
that and a remainder of 5 don't forget to place your decimal piont
step 3:place 0 at the back of 5 it then becomes 50 so we can easily divide 8 by 50
50 divided by 8 is 6 that gives a remainder of 2
step 3:place 0 at the back of 2 like earlier then it becomes 20
divide 20 by 8 ,this gives you 2 and a remainder of 4
step 4:place 0 at the back of 4 as done earlier , divide 40 by 8
it gives you 5 with no remainder

In 2013, there were 50,304 runners in the New York City Marathon. Each runner runs a distance of 26.2 miles. If you add together the total number of miles for all the runners, how many times would they run back and forth from the earth to the moon? Consider the distance from the earth to the moon to be 2.389 x 105 miles.
The runners would be able to run 2 times back and forth from the earth to the moon if their distances were added.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
There are 50,304 runners and each runner runs a distance of 26.2 miles. Hence:
Total distance ran by runners = 26.2 miles * 50304 = 1317964.8 miles.
The distance from the earth to the moon is 2.389 x 10⁵ miles, hence:
Ratio of total distance to distance from earth to moon = 1317964.8 miles/ (2.389 * 10⁵) = 5.516
Time ran back and forth = 5.516 / 2 = 2.76
