Answer:
Eighth half-hour
Step-by-step explanation:
Given pattern:
1st half hour = 12 bows used2nd half hour = 9 bows used3rd half hour = 14 bows used4th half hour = 11 bows used5th half hour = 16 bows usedCalculate the differences between the number of bows used:
[tex]12\underbrace{}_{-3}9\underbrace{}_{+5}14\underbrace{}_{-3}11\underbrace{}_{+5}16[/tex]
Therefore, the pattern for the bows used is:
-3, +5, -3, +5, etc...If the pattern continues:
[tex]12\underbrace{}_{-3}9\underbrace{}_{+5}14\underbrace{}_{-3}11\underbrace{}_{+5}16\underbrace{}_{-3}13\underbrace{}_{+5}18\underbrace{}_{-3}15\underbrace{}_{+5}20[/tex]
6th half hour = 16 - 3 = 13 bows used7th half hour = 13 + 5 = 18 bows used8th half hour = 18 - 3 = 15 bows used9th half hour = 15 + 5 = 20 bows usedCreate a table with the given and found data, and add a cumulative total column:
[tex]\begin{array}{c|c|c}\vphantom{\dfrac12} \textsf{Half Hour} & \textsf{Bows used per half hour} & \sf Cumulative\; total\\\cline{1-3} \vphantom{\dfrac12} \sf 1st & 12 & 12\\\vphantom{\dfrac12} \sf 2nd &9 &21 \\\vphantom{\dfrac12} \sf 3rd & 14&35 \\\vphantom{\dfrac12} \sf 4th & 11& 46\\\vphantom{\dfrac12} \sf 5th & 16& 62\\\vphantom{\dfrac12} \sf 6th & 13& 75\\\vphantom{\dfrac12} \sf 7th &18 & 93\\\vphantom{\dfrac12} \sf 8th & 15& 108\\\vphantom{\dfrac12} \sf 9th & 20& 128\\\end{array}[/tex]
If Clifford has a total of 100 bows, he will run out of bows during the eighth half-hour.

Lin and Noah are solving the equation `7(x+2)=91`. Lin starts by using the distributive property. Noah starts by dividing each side by 7. Show what Lin's and Noah's full solution methods might look like.
HELPPP
Answer:
Step-by-step explanation:
Lin’s method
- multiply both x and 2 by 7
7x+14 = 91
- add -14 at both members
7x+14-14 = 91-14
7x = 77
- divide the two members by 7
x = 11
Noah’s method
- divide the two members by 7
x+2 = 13
- add -2 at both members
x+2-2 = 13-2
x = 11
Answer:
The solution is x=11
Step-by-step explanation:
The original equation is
7(x+2)=91
Lin uses the distributive property, which states that
a (x+y) = ax + ay
By applying the property to this case,
7(x+2)=91
7x+14=91
Then we subtract 14 on both sides:
7x+14 - 14 = 91-14
7x=77
Finally, we divide by 7 on both sides:
7x÷7 = 77÷7
x=11
Noah starts by dividing each side by 7, so he gets:
7(x+2)÷7 = 91÷7
x+2= 13
Then he can subtract +2 from both sides:
x+2-2 =13 - 2
x=11
So, they get the same result. The similarity between the two methods is that they both divide by 7, while the difference is that Lin has to subtract 14, while Noah has to subtract 2.

Maria and Juan are married, filing jointly. Their taxable income is $154,849. Use the table below to write an equation to determine their tax. Then calculate their tax.
Answer:
The right answer is "$31,399.75".
Step-by-step explanation:
The given value is:
Taxable income,
= $154,849
According to the question,
The tax amount will be:
= [tex]8,962.50 + (154,849 - 65,100)\times 25 \ percent[/tex]
= [tex]8,962.50+(89,749)\times 25 \ percent[/tex]
= [tex]8,962.50+22,437.25[/tex]
= [tex]31,399.75[/tex] ($)

The Thompson Family has a garden in their backyard. They take the produce each week to a local farmers market. Use the graph to answer question. What percent of the garden is tomatoes? Show work for full credit.
Answer: 20%
Step-by-step explanation:
The total # of plants is 30, so what you do is take the # of tomatoes over 30. (6/30) and then x/100 so the formula would be 6/30=x/100. Then you would cross multiply and solve! so your answer is 20%

Answer:
D
Step-by-step explanation:
Here, we want to select the possible table of the given line
Let us look at the intercepts
On the x-axis, we have an intercept at x = 2
On the y-axis, we have an intercept at y = -4
This means that when y = 0, x = 2 and when x = 0, y = -4
Looking at the options, the table that supports this answer is the table of option D

she still has to multiply by two because there are 2 each of the rectangles that she is calculating the area of. the correct formula would be 2(8*16+8*12+16*12)
Answer:
No.
Step-by-step explanation:
The surface area formula of a right rectangular prism is 2(wl * hl * hw). The height is 12, width is 8, and length is 16. (these sides don't matter, the area will always be 832.) Anyway, our dear Muna did all the steps right, except she has to multiply all that she did by 2. She forgot to do that part
in Joe's fish tank, there are 6 goldfish and 12 snails. How does the ratio 6:18 describe Joe's fish
tank?
Hey there!
The ratio 6:18 describes Joe's fish tank, certainly. But how?
Note that this ratio can be written as 6 to 18, 6/18, and 6 out of 18.
This ratio can show this: For every 6 goldfish in Joe's tank, there are 12 snails.
Great question!
Hope I helped, please feel free to comment below should you have any questions/comments/concerns!
The correct option is C.
Given that,
in Joe's fish tank, there are 6 goldfish and 12 snails.Here 6:18 denotes that the number of goldfish to the total no of animals.
Here total no of animals could be
= 6 + 12
= 18

Answer:
x = 50, y = 61
Step-by-step explanation:
y + 8 + 2x + 11 = 180°
y + 2x = 161°
the total of the interior angles of the 5 sided polygon is:
(180 x 5) - 360 = 540°
540 = 98 + 98 + 125 + 108 + 2x + 11
2x = 100
x = 50°
y + 2(50) = 161
y = 61°

A lamp produced a shadow of a man standing in the middle of a stage.
21° 19°
25 meters
How long is the shadow?
;
Answer: 11.38
Step-by-step explanation:
I just did this math nation question and that’s what they said the answer was
The solution is, Length of the shadow = 11.4 m.
What are trigonometric relations?Trigonometry can be stated as the study of the relationships between the angles and the lengths of the sides of triangles.
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
Given the graph:
The length of the shadow = y - x.
• To find x:
tan 21 = x/25
so, we get,
x = 25 * tan 21
=9.6m
• To find y:
tan 40 = y/25
so, we get,
y = 25* tan40
= 21m
Length of the shadow:
length = 21 - 9.6 m
= 11.4m
so, we get,
Length of the shadow = 11.4 m
