If 65% of a shape is shaded, what percent is NOT shaded?

Answer:

m= -2

Step-by-step explanation:

The solution is m = -2

Step-by-step explanation:

The given rational equation is

We'll simplify the left hand side first.

The LCD is (m+4)(4-m)

Hence, multiply and divide the first term by 4-m and second by m +4

Use the difference of squares rule

We can now add the numerator

On simplifying, we get

Add the like terms

Multiply and divide left hand side by -1

We can cancel the denominator

Divide both sides by 8

The solution is m = -2

Answer:D. 0.039

Step-by-step explanation:

The probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have the total number of male students = 70+50+60 = 180

So, the total number of outcomes = 180

Total number of male students who take humanities class = 70

Now, the probability = 70/180 = 0.388 ≈ 0.389

Thus, the probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.

The converse of a theorem is created by reversing the hypothesis and the conclusion of the theorem's statement. The correct multiple-choice answer is 'D. A statement formed by transposing what is to be proved by a theorem and what is given.'

The converse of a theorem is a logical statement where the elements of the theorem's statement are switched. If you have a theorem that states "If A, then B," the converse of that theorem would be "If B, then A." This essentially transposes the hypothesis and the conclusion. In the context of the multiple-choice options provided, the correct answer is D.

A statement formed by transposing what is to be proved by a theorem and what is given. It's important to note that even though a theorem is proven true, its converse is not necessarily true and must be proven separately if it is to be accepted as true.

Answer:

13.73

Step-by-step explanation:

Answer: 13.7345175425633 square feet

The rounding instructions are cut off, so it's not clear how you want to round this.

========================================================

Explanation:

The area of the square is 8*8 = 64 square feet.

The two unshaded semicircles combine to form a full circle of radius 4 ft. This circle has an area of A = pi*r^2 = pi*4^2 = 16pi square feet.

The shaded area is the result of taking the circle area away from the larger square area

shaded area = (area of large square) - (area of two semicircles)

shaded area = (area of large square) - (area of circle with radius 4)

shaded area = 64 - 16pi = exact value

shaded area = 13.7345175425633 = approximate value

Answer:

3.4

Step-by-step explanation:

Answer:

0<x<8.7

Step-by-step explanation:

for it to be a triangle, sum of two sides must be greater than the largest side.

so, if x is 8.4 or greater, it can't be a triangle since it is greater than the sum of 3.2 and 5.5

a side must be greater than 0

so , 0<x<8.7

Joshua's 15 ft ladder, if leaned against the wall to reach a height of 14.8 ft, would be at an unsafe angle less than 70° and thus, is not safe to use in this manner.

The student has asked whether Joshua's ladder, which is 15 feet long and is supposed to lean against a wall with the top at 14.8 feet above the ground, will be safe with an angle no greater than 70°. To determine this, we can use the trigonometric function cosine, which relates the adjacent side (the height at which the top of the ladder reaches the wall) to the hypotenuse (the length of the ladder) in a right-angled triangle. The cosine of the maximum safe angle (70°) should therefore be equal to or greater than the ratio of the height of the ladder against the wall (14.8 feet) to the length of the ladder (15 feet).

We calculate the cosine of 70°: cos(70°) ≈ 0.342. Then we calculate the ratio 14.8/15 which equals 0.9867. Since 0.9867 is much greater than 0.342, it means the ladder will form an angle that is less than 70°, which is not within the safe range as per Joshua's requirement.

Therefore, it is not safe for Joshua to lean the ladder in this manner because the angle formed will be steeper than the maximum safe angle of 70°, which may result in the ladder slipping.

The expressions for the volume of the composite pyramid figure is given by A = One-third(7)(12)(10) - One-thirdπ(32)(10) = 280 - 30π

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

A pyramid with a square base with dimensions 12 by 7 is shown. A cone is cut out of the center of the pyramid.

The cone has a height of 10 and a diameter of 6.

The correct expression to represent the volume of the composite figure (the shaded figure) is:

One-third(7)(12)(10) - One-thirdπ(3)²(10) = 280 - 30π

So the expressions that apply are:

One-third(7)(12)(10) - One-thirdπ(32)(10) = 280 - 30π

Hence , the volume of pyramid is 280 - 30π

The days will the chocolate last is A) More than 12 days . Therefore A) More than 12 days is correct .

One chocolate bar lasts for 12 days because 1 / (1/12) = 12

Two chocolate bars last for 24 days because 12 * 2 = 24

So, even if Luna has one s'more a day, the chocolate will last for more than 12 days.

The other options are not as likely:

Option (B) is less likely because two chocolate bars would still last for more than a day, even if she had one s'more a day.

Option (C) is possible, but it's less likely than option (A) because two chocolate bars would provide more than 12 s'mores worth of chocolate.

Therefore, the answer is A) More than 12 days.

The value of b such that the determinant is 24 will be 8.

matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.

Matrix applications are crucial in many fields, including computer graphics, where they have been used to explain image transformations and other adjustments.

Given the matrix,

Its determinant will be

-5( -42 + 4b ) - 4(30 - 24 ) + 1(5b - 42 ) = 24

Answer:

[tex] g(x) = (x-2)^2 -6(x-2) +3[/tex]

[tex] g(x) = x^2 -4x +4 -6x +12 +3[/tex]

[tex] g(x) = x^2 -10 x +19[/tex]

[tex] g(x) = x^2 -10 x + 25 +19 -25[/tex]

[tex] g(x) = (x-5)^2 -6[/tex]

[tex] y= (x-h)^2 -kk[/tex]

Where h,k represent the vertex and we got:

[tex] (h,k)= (5,6)[/tex]

(5,6)

Step-by-step explanation:

We have this original function given :

[tex] f(x) = x^2 -6x +3[/tex]

And we want to find the vertex for this new function [tex] g(x) = f(x-2)[/tex] and we have:

[tex] g(x) = (x-2)^2 -6(x-2) +3[/tex]

And solving the square we got:

[tex] g(x) = x^2 -4x +4 -6x +12 +3[/tex]

And adding similar terms we got:

[tex] g(x) = x^2 -10 x +19[/tex]

Now we can complete the square like this:

[tex] g(x) = x^2 -10 x + 25 +19 -25[/tex]

[tex] g(x) = (x-5)^2 -6[/tex]

The general equation is given by:

This question is about Kamden, a mind-reading alien, guessing whether cards have a star on them using probability and counting.

The subject of this question is Mathematics. Kamden, a mind-reading alien, has each of his friends draw and look at a card, and he tries to guess whether the card has a star on it.

This task involves probability and counting. If there are a total of 'n' cards and 'm' of them have a star on them, the probability of Kamden guessing correctly is m/n.

For example, if there are 10 cards and 3 of them have a star, the probability of Kamden guessing correctly is 3/10 or 30%.

Answer:

50 miles

Step-by-step explanation:

60 divided by 30 = 5

5 miles = 10% of the trip

40% of the trip left to go

40% = 20 miles (5 x 4)

30 + 20 = 50

hope this helps!

To find the length of the whole trip, set up a proportion using the given information and solve for the missing variable. The whole trip is approximately 50 miles long.

To find the length of the whole trip, we can set up a proportion using the information given. We know that 60% of the trip is equivalent to 30 miles. We can set up the proportion:

60% / 100% = 30 miles / x

By cross-multiplying, we get:

x = (30 miles * 100%) / 60%

Calculating this, we find that the whole trip is approximately 50 miles long.
