Answer:

The answer is 42%.

Step-by-step explanation:

If we make a Venn diagram, we get 12% in the middle, meaning that 12% of people chose both coffee and juice.

54% is the total amount of people who chose coffee, including the % of people who chose coffee as well as juice.

So, we need to subtract 12% from 54%, therefore giving us 42%.

Which statements are true about the location of 3.28 on the number line? Check all that apply. A number line from 1.2 to 4.2. 3.
Juliette [100K]

Answer:

- 3.28 should be plotted between 3.2 and 3.4

- 3.28 is closer to 3.0 than 4.0.

- 3.28 is closer to 3.2 than 3.4.

Step-by-step explanation:

3.28 is located towards the positive side of the number line being a positive value. Since the value is located between 3.2 and 3.4, therefore it can be plotted between this two points.

Also 3.28 is known to be closer to 3.0 than 4.0 because the difference between 3.28 and 3.0 is lower than the difference between 3.28 and 4.

4-3.28 = 0.72(larger value)

3.28-3.0 = 0.28 (smaller value)

The smaller the difference, the closer the value of 3.28 to the value in consideration.

Similarly, 3.28 is closer to 3.2 than 3.4, due to their differences. The difference between 3.28 and 3.2 is lower than the difference between 3.28 and 3.4 as shown:

3.28 - 3.2 = 0.08(smaller)

3.4-3.28 = 0.12(larger)

Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest ra
Nookie1986 [14]
IN finding the interest we need to use the following formula:
 Interest= Principal x Rate x Time  or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R=  [<span>$20 + ($10 x $34)-320] / ($320 x 10 months)
                                          T=10 months</span>÷12 months=0.83<span>
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096</span>

What are the coordinates of the circumcenter of this triangle? Enter your answer in the boxes.
Juliette [100K]

Answer:

(2,1)

Step-by-step explanation:

We can see  that the given triangle.

The coordinates of A are (-1,5) .

The coordinates of B are (-1,-3).

The coordinates of C are  (5,-3).

Distance formula: \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

AB=\sqrt{(-3-5)^2+(-1+1)^2}=8 units

BC=\sqrt{(5+1)^2+(-3+3)^2}=6 units

AC=\sqrt{(5+1)^2+(-3-5)^2}=10 units

Pythagoras theorem:(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2}

AB^2+BC^2=8^2+6^2=100

AC^2=(10)^2=100

Therefore, AC^2=AB^2+BC^2

When a triangle satisfied the Pythagoras theorem then, the triangle is right triangle.

Hence, the given triangle is  a right triangle.

We know that circum-center of right triangle is the mid point of hypotenuse.

Mid-point formula:x=\frac{x_1+x_2}{2},y=\frac{y_1+y_2}{2}

Using this formula then, we get

Mid-point of hypotenuse AC is given by

x=\frac{-1+5}{2}=2,y=\frac{5-3}{2}=1

Hence, the circum-center of triangle is (2,1).
