A circular table has a diameter of 4ft.what is its approximate area?(use pi=3)

Answers

Good question if only because it approximates. I imagine you might have been told to do the question in your head.

Area = pi r^2
r = d/2
r = 4/2
r = 2 feet
pi = 3

Area = 3 * 2 * 2 = 12 square feet <<<<<< Answer.

Somewhere in 1 Kings Ch 7, the Bible makes reference to pi being 3. It's a pretty good estimate considering the number system the Bible used. 

A math club took a math test. Twelve of the members had an average score of 80. Eighteen of the members had an average score of 86. what is was the class average

Answers

12 x 80 = 960
18 x 86 = 1548
960 + 1548 = 2508
12 + 18 = 30
2508/30 = 83.6

The class average is 83.6
Let’s add the percentages up.
There were twelve people who had an average of 80. With this, you just have to believe they all received an 80%. The same with the score of 86.
12•80=960
18•86=1,548
Now add them together.
960+1,548=2,508
Now add the total students.
12+18=30
2,508/30
83.6
The class average is 83.6%

This is an isosceles triangle which means the triangle will have 2 of the same angles and sides. The sum of interior angles of a triangle is 180 degrees. 180-70= 110 then you divide by 2 since there are 2 angles you still need to find out. 110/2=55. Therefore, x=55 degrees

The probability of Jaden making a free throw is 15%. Predict the number of free throws that he can expect to make if he attempts 40 free throws.

Answers

6 divided by 40 is 15 percent so the answer is 6

We have been given that the probability of Jaden making a free throw is 15%.

Now, we have to predict the number of free throws that he can expect to make if he attempts 40 free throws.

In order to find the total number of free throws, we will find 15% of 40.

Therefore, the number of free throws should be

[tex]15\%  \text{ of  }40\\ \\ =\frac{15\times 40}{100} \\ \\ =\frac{600}{100} \\ \\ =6[/tex]

Therefore, the number of free throws that he can expect to make if he attempts 40 free throws is 6.

Two angles are complementary. If one angle measures 32 degrees, what is the measure of the second angle?

Answers

Hoi!

Complementary angles = 90°
Supplementary angles = 180°

To calculate the measure of the second angle, subtract 32 from 90.

90 - 32 = 58

The measure of the second angle is 58°. :)
Final answer:

If one angle measures 32 degrees, the measure of the second angle can be found by subtracting 32 from 90. Therefore, the second angle is 58 degrees.

Explanation:

Complementary angles are two angles whose sum is 90 degrees. So, if one angle measures 32 degrees, we can find the measure of the second angle by subtracting 32 from 90:

Second angle = 90 - 32

Second angle = 58 degrees

if triangle ABC is rotated 180 degrees about the origin, what are the coordinates of A?

Answers

Answer:

The coordinates of A is  [tex](-x_1,-y_1)[/tex].

Step-by-step explanation:

We are given that a triangle ABC is rotated 180 degrees about the origin .

We have to find the coordinates of A.

Let vertices of triangle ABC [tex]A(x_1,y_1),B(x_2,y_2) ,C(x_3,y_3)[/tex]

When we rotate the about 180 degrees then the coordinates changes like as

[tex](x,y)\rightarrow (-x,-y)[/tex]

When we rotate triangle ABC about 180 degrees then its vertices Ais ([tex]x_1,y_1)[/tex] change into [tex](-x_1,-y_1)[/tex]

Hence, the coordinates of A is  [tex](-x_1,-y_1)[/tex].

Final answer:

After rotating triangle ABC 180 degrees about the origin, the coordinates of point A, initially at the origin (0, 0), remain unchanged at (0, 0).

Explanation:

If triangle ABC is rotated 180 degrees about the origin, the coordinates of point A after the rotation can be determined by applying the rules of rotation in the Cartesian coordinate system. Since point A is at the origin, its initial coordinates are (0,0). A rotation of 180 degrees about the origin will essentially reflect a point over both the x-axis and y-axis, but the location of point A will remain unchanged because it is located at the center of rotation. Therefore, the rotated coordinates of point A will still be (0, 0).

Antoine is wrapping a block of cheese that is 22 centimeters long by 6 centimeters high by 10 centimeters wide with plastic wrap. What is the surface area of the cheese box?

Answers

The answer would be 824 sq. Centimeters
length = 22 cm
width = 10 cm
height = 6 cm

Surface area of a rectangular prism (cheese box) = 2B + PH
Word form ⇒ 2(Area of base) + (perimeter of base)(height)

Find the measurements needed for the formula.
Area of base = 22 × 10 = 220 cm²

Perimeter of base = 22 + 10 + 22 + 10 = 64 cm 

Height = 22 cm

Plug these into the formula.
2(220) + (64)(22) = 1,848

The SA of the cheese box is 1,848 cm².

convert to mixed number

= 7 1/2 yards per girl

Please solve both and tell me how!

Answers

PART A:
To determine k, you need to throw x + 3 into the original function:

[tex]f(x)= x^{2} -2x-24[/tex]

So, [tex]f(x+3)[/tex] would be:

[tex]f(x+3)= (x+3)^{2} -2(x+3)-24[/tex]

Doing some FOILing/distributing, we get:

[tex]f(x+3)= (x^{2}+6x+9) -2x-6-24[/tex]

Doing some clean up/combining like terms, we get:

[tex]f(x+3)= x^{2}+4x-21[/tex]

Now, it should be clear that k=4, since k is the coefficient in front of the x term (it's the "b" in [tex]ax^2+bx+c[/tex]).

PART B:
There are several ways to find the zeros, but perhaps the easiest is to factor the result from Part A:

[tex]f(x+3)= x^{2}+4x-21=(x+7)(x-3)[/tex]

From those factors, we know that zeros occur at x = -7 and x = 3 (answers A and E). 

By the way, you can check the logic of these zeros if you know about shifts/translations. [tex]f(x+3)[/tex] is a 3 unit left shift from the original function, which has zeros at x = -4 and x = 6. Well, x = -7 is 3 units to the left of x = -4. And x = 3 is 3 units to the left of x = 6. So everything seems to check out. 

A father is ten times as old as his daughter. In 5 years he will be just five times as old as she will be. How old are they now? HELP PLEASEEE

Answers

she is four years old which makes her father 40 that's ten times her age in five years she'll be 9 and he will be 45 which is 5 times her age. hope that helped you out.
Final answer:

The given problem is an algebraic equation where the daughter's age is denoted as 'x' and the father's age as '10x'. An equation is formulated to solve for 'x' based on future ages. The solution to the problem is that the daughter is 5 years old, and the father is 50 years old.

Explanation:

The problem asked is a classic example of algebra problem solving. We are told that a father is 'ten times as old as his daughter', and in five years, 'he will be just five times as old as she will be'. Let's denote the daughter's current age as 'x'. Therefore, the father's current age will be '10x'.

In five years, the daughter will be 'x+5' and the father will be '10x+5'. At this future moment, the father is 'five times as old as the daughter', so we can create the equation: 10x + 5 = 5(x + 5). Solving this equation leads to 'x=5'. So, the daughter is 5 years old and the father is 50 years old.
