A irrational number can be a decimal, but can never be a fraction.
A deli that just opened was giving out free mini sandwiches. A sample of 50 likely customers was surveyed about which sandwich they preferred. The
people surveyed included 12 people who said they preferred the roast beef
Sandwich. Based on this information, how many of the first 150 sandwich
orders should the deli predict will be for roast beef?
Answer:
i think it's 36, but i'm not sure
Step-by-step explanation:
12 is 24 percent of 50, and 24 percent of 150 is 36
A ratio shows us the number of times a number contains another number. The number of people who prefer roast beef sandwiches out of 150 people is 36.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that in a sample of 50 people, 12 were the people who preferred roast beef sandwiches. Therefore, the ratio of people who prefer roast beef sandwiches to the total number of people surveyed will be,
[tex]\dfrac{\text{People who prefer roast beef sandwich}}{\text{People who were surveyed}} = \dfrac{12}{50}[/tex]
Similarly, if the ratio is applied to a group of 150 people,
[tex]\dfrac{\text{People who prefer roast beef sandwich}}{\text{People who were surveyed}} = \dfrac{12}{50}\\\\\\\dfrac{\text{People who prefer roast beef sandwich}}{\text{150}} = \dfrac{12}{50}\\\\\text{People who prefer roast beef sandwich}=36[/tex]
Hence, the number of people who prefer roast beef sandwiches out of 150 people is 36.

According to question diagonal needs to calculated.
The diagonal , and two sides of rectangle will forma a right angled triangle.
Right angle as it constitute a right angle of rectangle as well.
To understand more
construct a rectangle ABCD
then one of its diagonal will be AC if we take triangle ABC.
angle ABC will be right angled at B.
for triangle ABC . diagonal AC will be hypotenuse
So diagonal can be computed using Pythagoras theorem
which states that if a and b are two sides of right angled triangle containing the right angle then hypotenuse is given by [tex]\sqrt{a^2+b^2}[/tex].
____________________________________________
In the problem
two sides are of length 8.5 and 11 inches
So, diagonal is hypotenuse which can be calculated by [tex]\sqrt{8.5^2+11^2}\\=>\sqrt{72.25+121}\\=>\sqrt{193.25}\\=>13.90[/tex]
thus length of diagonal is 13.90 inches.

Find the equation of the line described below. Write the equation in slope-intercept form, if possible, and graph the line. Contains (1,2) slope=3
Answer:
The equation of the line is y = 3x - 1
Step-by-step explanation:
In this question, we are asked to write the equation of the line using a point on the line and the slope of the line.
Mathematically, the slope-intercept form of a line can be written as;
y = mx + c
where m is the slope of the line and c is the y-intercept of the line. Now back to the question, we can see that we have all that is required for the line asides the value of the y-intercept C
To get this, we plug the values in the question into the equation of the straight line.
Here, we say y = 2, x = 1 and m = 3
2 = 3(1) + c
c = 2-3
c = -1
Thus, the equation of the line is y = 3x - 1

Answer:
The area of the wrestling ring is 5.29π [tex]m^2[/tex]
Step-by-step explanation:
A sumo wrestling ring is circular and has a circumference of 4.6π meters.
To find its area, we need to first find its radius.
The circumference of a circle is given as:
[tex]C = 2 \pi r[/tex]
where r = radius
Hence, the radius of the ring will be:
[tex]4.6\pi = 2\pi r\\r = 4.6 /2 = 2.3m[/tex]
The radius of the ring is 2.3 m.
The area of a circle is given as:
[tex]A = \pi r^2[/tex]
Hence, the area of the wrestling ring (in terms of π) will be:
[tex]A = \pi * 2.3^2[/tex]
[tex]A = 5.29\pi[/tex] [tex]m^2[/tex]
The area of the wrestling ring is 5.29π [tex]m^2[/tex]

Two adjacent angles form a complementary relationship. One angle is twelve more than twice the other angle. Draw a picture to represent the situation. Then solve for each unknown angle measure.
Answer:
The angles are 26 and 64
Step-by-step explanation:
When two angles are complementary, what this means is that the add up to 90 degrees
Now, let’s say one of the angles is x, the other angle is 12 more than twice it; mathematically that would be 2x + 12
Since they add up to be 90, we have
x + 2x + 12 = 90
3x + 12 = 90
3x = 90-12
3x = 78
x = 78/3
x = 26
The other angle is 2x + 12 = 2(26) + 12 = 52 + 12 = 64
Two adjacent angles form a complementary relationship. One angle is twelve more than twice the other angle than the value of that two complementary angles are [tex]26^\circ[/tex] and [tex]64^\circ[/tex].
Given :
Two adjacent angles form a complementary relationship.One angle is twelve more than twice the other angle.The sum of two complementary angles is [tex]90^\circ[/tex]. Let one of the complementary angles be 'a' then the other complementary angle is (12 + 2a) according to the given data.
The mathematical expression of the sum of complimentary angles is:
a + (2a + 12) = [tex]90^\circ[/tex]
Now, open the parenthesis and further simplify the above ex[pression.
3a + 12 = 90
Subtract both sides by 12 in the above expression.
3a + 12 - 12 = 90 - 12
3a = 78
Now, divide both sides by 3 in the above expression.
a = [tex]26^\circ[/tex]
Now, the other complementary angle is (2(26) + 12 = [tex]64^\circ[/tex]).

Step-by-step explanation:
This is a geometric series.
15, 3, (3/5), ...
common ratio r = 3/15 = (1/5)
a_1 = 15
Formula for nth term: a_n = a_1 * r^(n-1)
a_n = 15 *(1/5)^(n - 1)
We want the sum of the first 7 terms.
S = a_1 * ( r^n - 1) / (r - 1)
here let n = 7
S = 15 * ( (1/5)^7 - 1 ) / ( (1/5) - 1)
S = 15 * ( (1/5)^7 - 1) / (-4/5)
S = 15 * (5/-4) * ( (1/5)^7 - 1)
S = ( -75/4 )* (-0.9999872)
S = - (-18.74976) = 18.749...
The sum is about 19
The sum of the first 7 terms of the following series is 18.74.
What is a geometric sequence?'A geometric sequence is a sequence where every term has a constant ratio to its preceding term. A geometric sequence with the first term a and the common ratio r and has a finite number of terms.'
According to the given problem,
Sequence = { 15, 3, [tex]\frac{3}{5}[/tex] }
Let the common ratio be r,
Let the first term of the sequence be a,
⇒ a × r = second term
⇒ 15 × r = 3
⇒ r = [tex]\frac{3}{15}[/tex]
⇒ r = [tex]\frac{1}{5}[/tex]
We know,
Sum of n number of terms in a geometric sequence can be represented by,
[tex]S_{n} = \frac{a(1-r^{7}) }{1-r}[/tex]
⇒ [tex]S_{7} = \frac{15(1-(\frac{1}{5})^{7} ) }{1-\frac{1}{5} }[/tex]
⇒ [tex]S_{7} = \frac{15(1-(\frac{1}{5})^{7}) }{\frac{4}{5} }[/tex]

Tomas brought $32.00 to the art supply store. He bought a brush, a sketchbook, and a paint set. The brush was 1 4 as much as the sketchbook, and the sketchbook cost 2 3 the cost of the paint set. Tomas had $4.50 left over after buying these items.
Answer:
The price of the sketchbook is $10, the price of the brush is $2.5 and the price of the paint set is $15.
Step-by-step explanation:
Let the price of the brush be b.
Let the price of the sketchbook be s.
Let the price of the paint set be p.
The brush was 1/4 as much as the sketchbook. This means that:
b = 1/4 * s = s/4_______________(1)
The sketchbook was 2/3 the cost of the paint set. This means that:
s = 2/3 * p
=> p = 3s/2 __________________(2)
Initially, he had $32.00 and after buying all the items, he had $4.50 left with him. This means that:
b + s + p + 4.50 = 32.00 ___________(3)
Put (1) and (2) in (3):
=> s/4 + s + 3s/2 + 4.50 = 32.00
Collect like terms and simplify:
11s/4 = 32.00 - 4.50 = 27.5
=> s = (27.5 * 4) / 11
s = $10
Put this back in (1) and (2):
b = 10 / 4 = $2.5
and
p = (3 * 10) / 2 = $15
The price of the sketchbook is $10, the price of the brush is $2.5 and the price of the paint set is $15.
