Answer:

Step-by-step explanation:

Answer:

18°

Step-by-step explanation:

sum the parts of the ratio, 1 + 4 + 5 = 10 parts

The sum of the 3 angles in a triangle = 180° , then

180° ÷ 10 = 18° ← value of 1 part of the ratio

Since 1 is the smallest part of the ratio it represents the smallest angle, thus

smallest angle = 18°

The total number of students surveyed is 88 if the survey asked students whether they would like a drama club, a step team, both clubs, or neither club.

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

A survey asked students whether they would like a drama club, a step team, both clubs, or neither club.

We can find the number of students surveyed by the Venn diagram:

The data:

• 34 students would like a drama club.

• 27 students would like a step team.

• 14 students would like both.

• 13 students would like neither.

From the Venn diagram:

The total number of students surveyed = 34 + 27 + 14 + 13

The total number of students surveyed = 88

Thus, the total number of students surveyed is 88 if the survey asked students whether they would like a drama club, a step team, both clubs, or neither club.

55+25h=t

Step-by-step explanation:

Answer:

Brandon paid $12.00.

Step-by-step explanation:

To solve, you simply must multiply 15 by 0.8. You multiply by 0.8 and not 0.2 because you are calculating 80% of the original cost, which is the same thing as 20% off.

15 x 0.8 = 12

Answer:

because  m || n and x || y => ∠6 = ∠11 = 112°

Step-by-step explanation:

Answer:

f(2)= -2

g(2)= 12

Step-by-step explanation:

To solve this we use the substitution method. Since f(2) is your variable, we will plug the x-value of 2 into each equation

f(2)= 2(2)^2-5(2)

f(2)=8-10

f(2)= -2

If the same variable is used for both equations then g(x) would be g(2) as well leaving you with

g(x) = 3x^2

g(2)= 3(2)^2

g(2)=12

Answer:

[tex] \rm t = \dfrac{5 - b}{2} [/tex]

Step-by-step explanation:

Solve for t:

[tex] \longrightarrow [/tex] 5 - b = 2t

5 - b = 2t is equivalent to 2t = 5 - b:

[tex] \longrightarrow [/tex] 2t = 5 - b

Divide both sides by 2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{2t}{2} = \dfrac{5 - b}{2} [/tex]

[tex] \sf \dfrac{2}{2} [/tex] = 1:

[tex] \longrightarrow [/tex] [tex] \sf t = \dfrac{5 - b}{2} [/tex]

Answer:

c = 9 - 17d

Step-by-step explanation:

9-c = 17d

9-c+c= 17d + c (add c to both sides)

9 = 17d + c (Simplify)

9 - 17d = 17d - 17d + c (subtract 17d from both sides)

9 - 17d = c (Simplify)

The equation can be solved for c as c = 9 - 17d.

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The given equation is 9 - c = 17d.

It can be solved in terms of c as follows,

9 - c = 17d

Subtract 9 from both sides to get,

9 - c - 9 = 17d - 9

=> -c = 17d - 9

Multiply both sides by -1 to get,

-1 × -c = (17d - 9) × -1

=> c = 9 - 17d

Hence, the given equation can be written in terms of c as c = 9 - 17d.

Answer:

1. The graph is linear because the precipitation increases at a steady rate of 3 mm every 15 minutes, or 0.2 mm per minute.

2.The slope of a line tells us how something changes over time, if the slope is found, the rate of change can be found. In this case it is telling us how the rain increases over time.

3.The graph is nonlinear. Because the rainfall total does not change at a constant rate, the points do not form a line.

4.The y intercept means the total rain that was present at the start of her recording, this means there was no rain when she first started her experiment.

Step-by-step explanation:

A linear function is such that has a constant rate, while a nonlinear function does not have a constant rate.

From the table that represents Monday rainfall, we have the following observations

This means that, the graph is a linear graph.

The slope in this case, is the amount of precipitation in one minute

From the table that represents Thursday rainfall, we have the following observations

This means that, the graph is a nonlinear graph.

This is the value of precipitation when the time is 0

From the table,

The precipitation at 0 minute is 0

Hence, the y-intercept, is 0

And yes, both graphs have the same y-intercept

Answer:

Using divisibility rules, it is impossible to have exactly the same number of kids in each of the diamonds

Step-by-step explanation:

Here, we want to use divisibility rule to check for the possibility of 152 kids showing for the kids

Since we need exactly equal number of kids in each of the diamonds, we are going to test the possibilities that we can share 152 to have the same number of campers in each of the diamond

Mathematically 152/6 = 25.3333

Since we have a remainder for the division, it is impossible to share the campers equally in the six diamonds if 152 kids show up for the camp

Step-by-step explanation:

I believe this is correct because if you divided 320 by 52 you get 6.15384615385 (or just 6.1) and since we did it to the Y operation we do it to the X operation and x, aka 8, divided by 6.1 equals 1.3.

Step-by-step explanation:

garden a:

perimeter=2xlength+2xwidth = 2x(5x(2x-3))+2x(2x-3) = 20x-30 + 4x-6 = 24x-36 / 12(2x-3) feet

garden b:

perimeter= 5x+5 + 4x+2 + 8x-8 = 17x - 1 feet

Answer:

Step-by-step explanation:

garden A

Width (W) = 2x - 3

Length (L) = 5(W)

               = 5 (2x - 3)

               = 10x - 15

Perimeter A = 2L + 2W  (perimeter of a rectangular garden)

                   = 2(10x - 15) + 2(2x - 3)

                   = 20x - 30 + 4x - 6

                   = 24x - 36

garden B

side 1 = 5x + 5

side 2 = 4x + 2

side 3 = 8x - 8

Perimeter B = sides (1 + 2 + 3)  

                   = 5x+5 + 4x+2 + 8x-8

                   = 5x + 4x + 8x + 5 + 2 - 8

                   = 17x - 1

Answer:

y = 10x^2 + x +21

Step-by-step explanation:

Step-by-step explanation:

x = -4y + 6

Now,

Substituting the value of x on 2x + 9y = 16, we get -.

2(-4y + 6) + 9y = 16

-8y + 12 + 9y = 16

y = 16 - 12

Now,

Substituting the value of y on 2x + 9y = 16, we get -

2x + 9(4) = 16

2x = 16 - 36

2x = -20

Hence,

The value of x is -10 and y is 4.

Answer:

n>5

Step-by-step explanation:

move the 20 onto the other side of the > by subtracting 20 on the left side and adding 20 on the right side

now you have

-3n>7n-20

move the 7n onto the other side the same way. subtract 7n from one side and add it to -3n. now you have

4n>20

this is called adding similar terms or inverse operations what ever you wanna call it. Now you divide N by 4. This is because 4n can be simplified to 4×N and the opposite of multiplication is division. you do the same on the other side.

n/4>20/4.

you are left with n>5

Answer:

n<2

Step-by-step explanation:

Subtract 20 from both sides 20-3n-20>7n-20

Simplify -3n>7n-20

Subtract 7n from both sides -3n-7n>7n-20-7n

Simplify again -10n>-20

multiply both sides by -1 (-10n)(-1) < (-20)(-1)

Simplify 10n<20

Divide both sides by 10 Then you get your answer
