Answer:
5.7 beads
Step-by-step explanation:
Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments.
We are told in the Question that:
the compartments in each case hold the same number of beads and none are left over
Hence, let the number of beads in each compartments = x
Therefore:
8x + 6x = 80 beads
14x= 80 beads
x = 80 beads/14
x = 5.7142857143 beads
x ≈ 5.7 beads
Hence, she can sort the beads into 5.7 beads per compartments

Step-by-step explanation:
The easiest way to think about it is that the angle looks a little smaller than a right angle (90 degrees) therefore 85 degrees is correct.

The ratio of the number of adults to the number of children at the resturant is 3:7. Identify the choices below that represent an equivalent ratio. Choices: A: 6:14 B: 8:12 C: 15:35 D: 21:9 E: 30:70
Answer: A: 6:14
C: 15:35
E: 30:70
Step-by-step explanation:
From the question, we are given that the ratio of the number of adults to the number of children at the resturant is 3:7.
The choices below that represent an equivalent ratio goes thus:
A: 6:14
This can be represented as: 6/14. The common factor is 2 and we reduce to lowest term which would be: = 3/7 = 3:7
This is an equivalent ratio.
B: 8:12
This can be represented as: 8/12. The common factor is 4 and we reduce to lowest term which would be: = 2/3 = 2:3
This is not an equivalent ratio.
C: 15:35
This can be represented as: 15/35. The common factor is 5 and we reduce to lowest term which would be: = 3/7 = 3:7
This is an equivalent ratio.
D: 21:9
This can be represented as: 21/9. The common factor is 3 and we reduce to lowest term which would be: = 7/3 = 7:3
This is not an equivalent ratio.
E: 30:70
This can be represented as: 30/70. The common factor is 10 and we reduce to lowest term which would be: = 3/7 = 3:7
This is an equivalent ratio.
The correct options are A, C,and E.

Two car services offer to pick you up and take you to your destination. Service A charges 40 cents to pick you up and 30 cents for each mile of your trip. Service B charges $1.10 to pick you up and charges c cents for each mile.
A) Match the services to the lines l and m
B) For service B, is the additional charge per mile greater or less than 30 cents per mile of the trip? Explain your reasoning
Answer/Step-by-step explanation:
a.) Service A charges of 40 cents to pick you up is the initial value (y-intercept). Form the graph, the line that has a y-intercept of approximately 40 cents is line m.
Also, the initial value of line l is $1.10 from the graph, which is the pick up cost that Service B charges. Therefore,
Line m = Service A
Line l = Service B
b.) The additional charge of service B = the slope of line l. Let's calculate the slope to see if it's greater than or less than 30 cents per mile of the trip.
Using two points on line l, (0, 1.10) and (7, 2.5)
Slope = change in y/change in x = (2.5 - 1.10)/(7 - 0)
= 1.4/7 = 0.2
Additional charge per mile for service B is $0.2 = 20 cents.
Therefore we can conclude that the additional charge per mile for service B is less than 30 cents/mile of the trip.
For which regular polygon is 30 degrees the smallest angle of rotational symmetry?
•given that is smallest angle of rotational symmetry for a regular polygon is 30
•we have to find the number of side does the regular polygon have
•if we can rotate of figure around a center point be fewer than 360° and the figure appears and change then the figure has the rotation symmetry
Hence,12 number of sides the polygon.no. of side= 360/ smallest angle at centre=12

A football team scored 3 touchdowns, 3 extra points, and 4 field goals. Write an expression to represent the total points the football team scored. Use t to represent the number of points for a touchdown Use e to represent the number of points for the extra point Use f to represent the number of points for a field goal Write the equation using the "WIRIS editor" button
Answer:
The answer is below
Step-by-step explanation:
A football team scored 3 touchdowns, 3 extra points, and 4 field goals.
a. Write an expression to represent the total points the football team scored.
b. Write another expression that is equivalent to the one written above.
c. If each touchdown is worth 6 points, each extra point is 1 point, and each field goal is 3 points, how many total points did the team score?
Solution:
a) Let t represent the number of points for a touchdown, e represent the number of points for the extra point and f represent the number of points for a field goal.
Total points = 3(t) + 3(e) + 4(f) = 3t + 3e + 4f
b) Total points = 3t + 3e + 4f OR
Total points = t + t + t + e + e + e + f + f + f + f OR
Total points = 3(t + e) + 4f
c) Total points = 3(t + e) + 4f = 3(6 + 1) + 4(3) = 3(7) + 4(3)
Total points = 21 + 12 = 33 points
The sum of the points the team has from different point gaining options
give the total number of points the team scores.
[tex]\underline{\mathrm{The \ total \ points \ the \ football \ team \ scored } = 3 \cdot t + 3 \cdot e + 4 \cdot f}[/tex]Reasons:
The number of touchdowns by the football team, t = 3
Number of extra points by the football team, e = 3
Number of field goals by the team, f = 4
Therefor, the total number of points, P = 3·t + 3·e +4.f
The specified editor is an equation editor, which can be used to write mathematical equations.
Using an equation editor, we have;
[tex]\mathrm{The \ total \ points \ the \ football \ team \ scored } = 3 \cdot t + 3 \cdot e + 4 \cdot f[/tex]

Answer: Choice C. y = (-1/2)x+7
=========================================================
Explanation:
The slope of the graphed line is -1/2 because we drop down 1 unit on the y axis each time we move to the right 2 units along the x axis. We could apply the slope formula for any two points on the diagonal line to also get a slope of -1/2.
The slope formula is m = (y2-y1)/(x2-x1).
Any two parallel lines have the same slope, but different y intercepts. So the parallel line will also have slope -1/2. Right away we can see the answer must be choice C. This is the only equation with slope -1/2 of the choices given.
Recall that slope intercept form y = mx+b has m as the slope. Not to be confused with the label m of the graphed line.
Note how plugging x = 6 into the equation for choice C leads to...
y = (-1/2)*x + 7
y = (-1/2)*6 + 7
y = -3 + 7
y = 4
Showing that (x,y) = (6,4) is on the equation y = (-1/2)x + 7. This confirms the answer.
---------------------------
Let's say we didn't have multiple choice answers to pick from, and instead it was fill in the blank. To find the y intercept b, we can do the following
y = mx+b
y = (-1/2)x + b ... plug in given slope m = -1/2
4 = (-1/2)*6 + b .... plug in the given point (x,y) = (6,4)
4 = -3 + b
4+3 = -3+b+3 ... adding 3 to both sides
7 = b
b = 7
Knowing that m = -1/2 and b = 7, we can update y = mx+b into y = (-1/2)x+7
