Find the area of the figure.

Answer:

B. 5/2

Step-by-step explanation:

We can just find the slope by using the two points.

delta y/ delta x = slope equation

(3,-1) (5,4)

4- -1/5-3 = 5/2

Answer is B, slope is 5/2

3.) 75%

Answer:

the slope

Step-by-step explanation:

m = slope

Answer: 4(4b - 5)(b + 5)

Step-by-step explanation:

All have a common factor of 4

4(4b^2 + 15b - 25)

--------------------------------------------------------------------------------------------------------------

Now you need to find two numbers that:

a) multiply to -100 (the a term * the c term = 4 * -25)

b) add to 15 (the b term)

After a little thinking, we can determine that the two numbers are:

20 and -5

--------------------------------------------------------------------------------------------------------------

Now we can rewrite the middle term as 20b - 5b (notice how it still equals 15b)

4(4b^2 + 20b - 5b - 25)

--------------------------------------------------------------------------------------------------------------

4((4b^2 + 20b) + (-5b - 25))

Group the terms (associative property)

--------------------------------------------------------------------------------------------------------------

Take out a common factor from each

4(4b(b + 5) - 5 (b + 5))

--------------------------------------------------------------------------------------------------------------

Now we can factor by grouping

4(4b - 5)(b + 5)

--------------------------------------------------------------------------------------------------------------

Answer:

y=4sin(1/4x)

Step-by-step explanation:

1. Either sin or cos graph

y=asin(b(x-c))+d or y=acos(b(x-c))+d

a = amplitude

b = period (2π/b = answer)

c = x-shift (negative)

d = y-shift (positive)

2. Graph each possibility

a = 4

b = 2π/8π = 1/4

c = 0

d = 0

y=4sin(1/4x) or y=4cos(1/4x)

Answer:

Question 957121: By what percent will a fraction increase if its numerator is decreased by 30% and its denominator is decreased by 50%?

If the numerator is decreased by 30% and its denominator is decreased by 50% the new fraction becomes (0.7x/0.5y)=1.4(x/y)

The increase=(1.4-1)*100=0.4*100=40%

Answer:The anwser is yes

Step-by-step explanation: As you can see both triangles look the same if you flip them around but ones smaller so its not congruent. That is why they are simeler    its like a p and a q just flip the q and you have a p. hope it helps. :p

Answer:

18 2/3

Step-by-step explanation:

12 1/3+6 2/6

12 1/3+6 1/3= 18 2/3

Answer:

18 2/3

Step-by-step explanation:

12 1/3 + 6 2/6

add the whole numbers

then make the 1/3 into 2/6 bc you need to make like denominators

then add 2/6 and 2/6 which is 4/6

to get simplest form you need to divide by 2 and on top and bottom and get 2/3

Answer:

a) 0.3125

b) 45

Step-by-step explanation:

Remark

5 students own a smart phone

11 do not.

Part A

The probability of owning a smart phone is 5/16. Where did the 16 come from.? You must use a total for the sample. You can't choose someone without a smart phone and figure out the probability of doing that if you use 11  in the denominator.

So the answer is 5/16 = 0.3125

Part B

You have to set up a proportion for this.

x / 144 = 5/16  

Notice where the 144 goes. It is across from 16. Both of them represent the total number of students. Multiply both sides by 144

x * 144 / 144 = 5 * 144/16

x = 720 / 16

x = 45

Since the product of variables in inverse proportion is constant, the equation is [tex]\boxed{xy=126}[/tex]

Answer:

Step-by-step explanation:

The square indicates that the total angle is 90 degrees so

d+59=90

d=90-59

d=31 degrees

Answer:

11.25

Step-by-step explanation:

You get the 45 dollars then you do 0.45 then you times it by 25

Hello There!

The following polygon shown is a triangle with the following dimensions

height - 4

base - 7

Given this information we need to find the area

Remember the formula for area of a triangle is

[tex]A=\frac{1}{2} bh[/tex]

where b = base and h = height

given the information all we need to do is plug in the values into the formula

so...

[tex]A=\frac{1}{2} 4*7\\4*7=28\\\frac{28}{2} =14\\A=14[/tex]

Hence, the area of the triangle is 14 square units
