Answer:
220 cases
Step-by-step explanation:
Each pallet contains 40 cases of tiles.
The yard has 10 complete pallets.
The total number of cases of tiles is therefore:
40 * 10 = 400 cases
If 180 cases are removed for the customer, then the number of cases of tiles remaining is:
400 - 180 = 220 cases
220 cases of tiles will be remaining.

Answer:
36 squared units
Step-by-step explanation:
So you can draw "made up lines" or I guess lines you draw yourself to create 2 rectangles. Check attachment.
The first rectangle is a square and has sides 3 and 3, so you get the area of 9.
The second, has sides 9 and 3, so you get the area of 27
Since you are trying to find the entire thing, you add 27 and 9 to get 36
After Jeremy runs across the width of the building, he must run down a ramp to the next building. Use the following portion of the picture to set up a ratio.
a.sin=70 =(4/x)
b. cos70 = (4/x)
c. cos 70 =(x/4)
d. sin 70 = (x/4)
Answer:
[tex]b.\ cos 70 =\dfrac{4}x[/tex] is the correct answer.
Step-by-step explanation:
First of all, let us label the diagram as shown in the attached figure.
OR = 20'
QS = 16'
[tex]\triangle OPQ[/tex] is the right angled triangle that we get.
[tex]\angle P=90^\circ[/tex]
[tex]\angle O =70^\circ[/tex]
From the given figure symmetry, we can clearly see that:
Side OP = OR - QS
OP = 20 - 16 = 4'
Now, let us use trigonometric identity of cosine in [tex]\triangle OPQ[/tex].
[tex]cos\theta = \dfrac{Base}{Hypotenuse}[/tex]
[tex]cosO= \dfrac{OP}{OQ}\\\Rightarrow cos70^\circ= \dfrac{4}{OQ}[/tex]
Let the distance of ramp, OQ = x'
So, the above ratio becomes:
[tex]cos70^\circ= \dfrac{4}{x}[/tex]
So, the correct answer is:
[tex]b.\ cos 70 =\dfrac{4}x[/tex]

Step-by-step explanation:
The question is incomplete. The complete question is
Carl, Gilda, Conroy, and Kyla are the four candidates in a school election. Carl received 1/5 of the votes, Gilda received 10% of the votes, and Conroy received 1/4 of the votes. If Kyla received all of the remaining votes, what percentage of the votes did she receive? A. 45\% B. 55\% C. 20\% D. 50\%
Solution:
The total percentage of the votes that is spread among the 4 contestants is 100%
Carl received 1/5 of the votes. It means that the percentage of votes that Carl received is
1/5 × 100 = 20%
Gilda received 10% of the votes.
Conroy received 1/4 of the votes. It means that the percentage of the votes that Conroy received is
1/4 × 100 = 25%
Therefore, if Kyla received all of the remaining votes, then the percentage of the votes that she received is
100 - (20 + 10 + 25) = 45%
Answer:
40%

border
A special shape is 2.02 m long and 1.22m wide
A double row of tiles makes a border.
Each tile is 2 cm by 2 cm.
How many tiles are needed to make the border?
A 648
B 624
C 632
D 640
E 636
Answer:
A. 648
Step-by-step explanation:
The special shape has a length of 2.02 m (202 cm) and width of 1.22 m (122 cm).
Given a tile of 2 cm × 2 cm, and that a double row of tiles make a border.
For a single row border,
the number of tiles required for its length = 202 /2 = 101
the number of tiles required for its width = 122/2 = 61
For a single row border, the total number of tiles for the perimeter of the special shape = 2 (101 + 61)
= 324
The number of tiles for a single row border is 324.
The number of tiles required to make the double row of tiles border = 2 (324)
= 648
The number of tiles required to make the border is at least 648.
The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes with a standard deviation of 0.5 minutes. We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes.
Refer to Exhibit 9-4. At 95% confidence, it can be concluded that the mean of the population is
Select one:
a.
significantly greater than 3
b.
not significantly greater than 3
c.
significantly less than 3
d.
significantly greater then 3.18
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
H0: µ = 3
For the alternative hypothesis,
H1: µ > 3
This is a right tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 3.1
µ = population mean = 3
s = samples standard deviation = 0.5
n = number of samples = 100
t = (3.1 - 3)/(0.5/√100) = 2
We would determine the p value using the t test calculator. It becomes
p = 0.024
Alpha = 1 - confidence level = 1 - 0.95 = 0.05
Since alpha, 0.05 > than the p value, 0.024, then we would reject the null hypothesis. Therefore, at 95% confidence level, it can be concluded that the mean of the population is significantly greater than 3.

If a population proportion is believed to be 0.60, how many items must be sampled to ensure that the sampling distribution of the sample proportion will be approximately normal
Answer:
[tex]n \geq 42[/tex]
Step-by-step explanation:
Data provided
P = 0.6
The calculation of sample size is shown below:-
Here the sampling distribution of proportion will be approximately normal, then follow the rule which is here below:-
[tex]np\geq 10\ and\ np (1 - p)\geq 10[/tex]
Now we will consider condition 2
[tex]np(1 - p)\geq \ 10[/tex]
[tex]n(0.6) (1 - 0.6) \geq \ 10[/tex]
[tex]n(0.6) (0.4) \geq\ 10[/tex]
[tex]n\geq \frac{10}{0.24}[/tex]
[tex]n \geq 41.66667[/tex]
or
[tex]n \geq 42[/tex]
Therefore for computing the required sample size we simply solve the above equation.
if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is _.
Answer: If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate 7-i5.
Step-by-step explanation:
We know that when a complex number [tex]z=a+ib[/tex] is a root of a polynomial with degree 'n' , then the conjugate of the complex number ([tex]\overline{z}=a-ib[/tex]) is also a root of the same polynomial.Given: 7+5i is a zero of a polynomial function of degree 5 with coefficients
Here, 7+5i is a complex number.
So, it conjugate ([tex]\overline{7+5i}=7-5i[/tex]) is also a zero of a polynomial function.
Hence, if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate 7-i5.
If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate which is 7 - 5i
The standard form of writing complex numbers with real and imaginary values is expressed as:
z = x + iy
The conjugate of the complex number will be y = x - iy
A complex number and its conjugate both have the same degree with coefficient.Given the polynomial 7 + 5i. If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate which is 7 - 5i

The number 20 is multiplied either by 4 or by 5, then the product is increased either by 3 or by 5, and then the sum is divided either by 6 or by 7. What is the final quotient, if it is a natural number?
Answer:
15
Step-by-step explanation:
If it was 20 × 4 = 80, 80 + 3 = 83 and 80 + 5 = 85 but neither of those numbers are divisible by either 6 or 7 so we know it's not 20 × 4. If we did 20 × 5 = 100, 100 + 3 = 103 and 100 + 5 = 105. Since 105 / 7 = 15 the answer is 15.
Answer:
15
Step-by-step explanation:
We try every possibility.
20 is multiplied either by 4 or by 5
20 * 4 = 80
20 * 5 = 100
then the product is increased either by 3 or by 5
80 + 3 = 83
80 + 5 = 85
100 + 3 = 103
100 + 5 = 105
the sum is divided either by 6 or by 7
None of the numbers are divisible by 6 since they are all odd.
Only 105 is divisible by 7.
105/7 = 15

Find the missing side of the triangle.
11 yd
10 yd
Answer:
Step-by-step explanation:
a^2+b^2=c^2
assuming that 11 and 10 are the shorter sides of the triangle
11^2+10^2=c^2
121+100=c^2
221=c^2
[tex]\sqrt{221}=\sqrt{c^2}[/tex]
this will equal 14.87 approximately
The missing side of the triangle is √221 yd .
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Let recall the Pythagorean theorem formula:
a² + b² = c²
Replacing by the values we have;
11² + 10² = c²
c² = 121 + 100
c² = 221
c = √221 yd
Therefore, the correct answer is √221 yd .

Answer:
D.
Step-by-step explanation:
To tell whether the domains can include 0, all you need to do is find where x = 0, and whether the y-value is real.
h(x) = sqrt(2x^2 + 5x - 3)
= sqrt(0^2 + 5 * 0 - 3)
= sqrt(-3)
Since this includes the square root of a negative number, h(0) is an imaginary number. That means that we can eliminate choices A and B.
If you look at the graph of w(x), when x = 0, there is a real value for the y-value on the graph. But, if you think about it, if you have 0 workers, there is no way that you can still be producing wrenches. So, the domain cannot contain 0.
