Twenty-five percent of 200 is what number?

Answer:

The number of cones sold was 88

Step-by-step explanation:

Let

x------> the number of cones sold

y----> the number of sundaes sold

we know that

[tex]1.10x+2.35y=294.20[/tex] ----> equation A

[tex]x+y=172[/tex] ----> equation B

using a graphing tool

we know that

The solution of the system of equations is the intersection point both graphs

The intersection point is (88,84)

see the attached figure

therefore

The number of cones sold was 88

The number of sundaes sold was 84

The area of a circle is found using the equation A = πr^2

r is the radius which is 1/2 the diameter

r = 14 /2 = 7

Area = π7^2

Area = 49π

Using 3.14 for π

Area = 49 x 3.14

Area = 153.86 square inches.  Round the answer as needed.

Final answer:

To find the area of a large round pizza with a diameter of 14 inches, use the formula A = (7 inches), which is half of the diameter, to find the area, resulting in approximately 153.86 square inches.

Explanation:

The area of a circle is calculated using the formula A = case and simplify the expression since the radius has only two significant figures. Utilizing an approximation for pi ( case 3.14), the area can be calculated as follows:

A = (3.14) (7 in) (7 in) approximately 3.14 (49 in²) approximately 153.86 in². Therefore, the approximate area of the pizza is 153.86 square inches.

Answer:

D) [tex]y\:<\:2x+2[/tex], [tex]y\:>\:-x[/tex]

Step-by-step explanation:

The blue boundary line has a y-intercept of 2 and a slope of  2.

It has equation : [tex]y=2x+2[/tex]

Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is

[tex]y\:<\:2x+2[/tex]

The blue boundary line passes through the origin and has slope [tex]-1[/tex].

Its equation is [tex]y=-x.[/tex]

Since the boundary line is not solid and the right half-plane is shaded, its inequality is [tex]y\:>\:-x[/tex]

The correct choice is D.

The correct choice is D: y < 2x + 2, y > -x.

The blue boundary line is represented by the equation y = 2x + 2.

Since the lower half-plane is shaded, the inequality is y < 2x + 2.

The blue boundary line also passes through the origin and has a slope of -1, which gives it the equation y = -x.

Since the right half-plane is shaded, the inequality is y > -x.

So, the correct choice is D: y < 2x + 2, y > -x.

Mode: the number that occurs the most in a set of data.

Although it's optional, I always like to order the numbers from least to greatest so it makes it easier to see what number repeats more than anything else.

Least to greatest - 40,41,42,43,44,45,46,47,48,49,49

The mode for this set of data is 49. The mode is 49 because 49 is the only number that occurs more than once. No other numbers in this set of data appear twice except 41.

Answer:

25/216 or 0.1157

Step-by-step explanation:

The probability of getting a 6 is 1/6.  

The probability of not getting a 6 is 5/6

We roll a die 4 times and want 2 sixes, and 2 not sixes.  

We want a combination of 2 sixes from 4 rolls, so we can use the binomial formula to solve this...

(4C2)(1/6)²(5/6)² = 6(1/36)(25/36) = (1/6)(25/36) = 25/216 = 0.1157

The long hand way of solving this is to list the 6 ways we can roll our desired result along with their probabilities...

We could get

6, 6, not 6, not 6      (1/6)(1/6)(5/6)(5/6) = 25/1296

6, not 6, 6, not 6       (1/6)(5/6)(1/6)(5/6) = 25/1296

6, not 6, not 6, 6       (1/6)(5/6)(5/6)(1/6) = 25/1296

not 6, not 6, 6, 6       (5/6)(5/6)(1/6)(1/6) = 25/1296

not 6, 6, not 6, 6       (5/6)(1/6)(5/6)(1/6) = 25/1296

not 6, 6, 6 not 6        (5/6)(1/6)(1/6)(5/6) = 25/1296

There are 6 different way this can happen, each having a probability of 25/196.  We add up the probabilities, getting 150/1296, which reduces to

25/216

[tex]3\sqrt{2}[/tex] x [tex]3\sqrt{3}[/tex]

Answer:

1) Factor the denominator and the numerator of each fraction.

2) Simplify.

3) Find the Least common denominator (LCD).

4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator (The LCD is the same denominator of the second fraction, so its numerator stays the same).

5) Apply Distributive property on the numerator and on the denominator.

6) Add like terms.

Step-by-step explanation:

The steps required to determine the sum of the two expressions are:

1) Factor the denominator and the numerator of each fraction:

[tex]\frac{3x+6}{x^2-x-6}+\frac{2x}{x^2+x-12}=\frac{3(x+2)}{(x-3)(x+2)}+\frac{2x}{(x-3)(x+4)}[/tex]

2) Simplify (Remember that [tex]\frac{(x+2)}{(x+2)}=1[/tex]):

[tex]\frac{3}{(x-3)}+\frac{2x}{(x-3)(x+4)}[/tex]

3) Find the Least common denominator (LCD). In this case this is:

[tex]LCD=(x-3)(x+4)[/tex]

4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator. As the LCD is the same denominator of the second fraction, its numerator stays the same:

[tex]=\frac{3(x+4)+2x}{(x-3)(x+4)}[/tex]

5) Apply Distributive property on the numerator and on the denominator:

[tex]=\frac{3x+12+2x}{x^2+x-12}[/tex]

6) Add like terms:

Step-by-step explanation:

If a, b and c are the lengths of the triangle's sides, then

[tex]a+b>c,\\ \\a+c>b,\\ \\b+c>a.[/tex]

Since

[tex]a=2x+2,\\ \\b=x+3,\\ \\z=n,[/tex]

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is A, 3x + 5 > n > x - 1.

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

(a+b) > c

(b+c) > a

(c+a) > b

Given the three sides of the triangle 2x + 2 ft, x + 3 ft, and n ft. Now using the triangle inequality theorem we can write,

2x + 2 + x + 3 > n  → 3x + 5 > n

2x + 2 + n > x + 3 → n > -x + 1

x + 3 + n > 2x + 2 → n > x - 1

Since x can not be a negative term therefore, we can write,

3x + 5 > n > x - 1

Hence, the correct option is A, 3x + 5 > n > x - 1.

Answer:

Nothing further can be done to this.

Step-by-step explanation:

There is nothing further that can be done with this equation.

The expression x^5 Y^6 doesn't simplify further as the bases differ. It means that 'x' is multiplied by itself five times, and 'y' is multiplied by itself six times.

The expression x^5 Y^6 is already in simplest form. Expressed in plain English, this represents 'x' raised to the power of 5, multiplied by 'y' raised to the power of 6. The exponents here denote that we are multiplying 'x' and 'y' by themselves for a specific number of times. For example, 'x' is multiplied by itself five times, and 'y' is multiplied by itself six times, as represented by this expression.

I want to let you know that the exponents are not to be combined in any way because the bases (x and y) are different. In other words, x^5 and Y^6 remain separated in expression. They cannot be simplified further.

Step-by-step explanation:

Find the number of apples in 8 pounds:

8 pounds x 16 ounces per pound = 128 ounces.

Divide total cost by cost for 8 pounds:

168 / 28 = 6

Multiply 6 by 128 ounces:

128 x 6 = 768 total ounces for $168.

Now divide total ounces by 5 ounces per apple:

768 / 5 = 153.6, round up to 154 apples.

Answer:

For $168 you could buy approximately 48 pounds of apples.

Step-by-step explanation:

6r -4 +8(15-r) + 23

expand brackets

6r -4 +120 -8r + 23

collect like terms

120 + 23 - 4 = 139

6r - 8r = -2r

139 - 2r

139 - 2r = -3r + 137

-137 from both sides

-2r = -3r -2

add 3r

R = -2

sub in both equations and see if you get the same value

-3r + 137

-3 (-2) + 137

6 +137 = 143

139 - 2r

139 - 2(-2)

139 + 4

143

yes they are equal

Final answer:

After simplifying the given expression by combining like terms and using the distributive property, we find that the simplified form is indeed -3r + 137, which means it is equivalent to the original expression.

Explanation:

To determine if the expression -3r + 137 is equivalent to the given expression 6r – r + 8(15 – r) + 23 – 6, we need to simplify the given expression.

Let's simplify the given expression step-by-step:

Therefore, the simplified form of the given expression is indeed -3r + 137, which means it is equivalent to the given expression.

Best regards

The volume of the right circular cylinder is approximately 1,261,852.32 cubic centimeters (rounded to the nearest hundredth).

To find the volume of a right circular cylinder, we use the formula:

V = πr2h

where V is the volume, π is the value of pi (approximately 3.14), r is the base radius, and h is the height. Plugging in the given values:

V = 3.14 * 562 * 128

V ≈ 3.14 * 3136 * 128

V ≈ 3.14 * 401,408

V ≈ 1,261,852.32

Therefore, the volume of the right circular cylinder is approximately 1,261,852.32 cubic centimeters (rounded to the nearest hundredth).
