Answer:83
Step-by-step explanation: A triangle is 180 degrees in total so if you take 90+45=135 then you subtract 52 from 135 and you get 83
so x=83
Robert painted 4/8 of each tile with green paint. He painted 52 tiles. What is the total amount of tiles that he painted green?
Please show an explanation to solve this problem. Thank you.
Answer:
The answer is 26
Step-by-step explanation:
All we do is multiply 4/8 by 52.
52 = 52/1
52/1 * 4/8 = 208/8
208/8 = 26
So the answer is 26.
Hope this helps! :)
What is the asymptote for the function?
I tried to do it but I can’t
Answer:
Horizontal Asymptote → y = 17
Step-by-step explanation:
Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]
Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]
Parent function has a horizontal asymptote as y = 0
If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]
When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.
Therefore, horizontal asymptote of the image function becomes y = 17.

Answer:x=-7
Step-by-step explanation:
Answer:
In this problem you have to get rid of the 13 so you take the opposite of the number which is -13 and subtract it by 13 and when you do this you have to do the same thing on the other side so you would do 48-13 and that would give you get 35 so -5x=35. This is not the same because on B it says positive 5x, and on A it is negative 5x.

3. The Mathville Zoo only has tigers and
ostriches. The zoo keeper says they have 22
animals and the animals have a total of 70 feet.
Find the number of each kind of animal?
9514 1404 393
Answer:
13 tigers9 ostrichesStep-by-step explanation:
Let t represent the number of tigers. Then the number of feet is ...
4t +2(22 -t) = 70
2t = 26 . . . . . . . . . subtract 44, collect terms
t = 13 . . . . . . . divide by 2; number of tigers
22 -t = 9 . . . . number of ostriches
The zoo has 13 tigers and 9 ostriches.

Answer:
x= -6
y= -5
Step-by-step explanation:
(x,y) = (-6, -5)
Answer:
(-6,-5)
x=-6
y=-5
Step-by-step explanation:
9x-7y=-19
5x-3y=-15
When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.
We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)
{9x-7y=-19}*3=
27x-21y=-57
{5x-3y=-15}*(-7)=
-35x+21y=105
Now, we combine the two equations.
27x-21y=-57
-35x+21y=105
-8x=48
Now, solve for x.
-8x=48
x=-6
Now we can plug x into one of the original equations to get y.
I will use 9x-7y=-19.
9(-6)-7y=-19
-54-7y=-19
Add 54 to both sides.
-7y=35
y=-5
We can put these values into an ordered pair: (-6,-5).

Able is carving a rectangular pyramid clock out of green quartz. The length of the rectangle base is 14 cm and the height of the clock is 9cm. If the clock needs to have a volume of 168cm3 what is the width of the base
Answer:
14cm
Step-by-step explanation:
Volume of the pyramid = Base area × height/3
V = BH/3
Base area = 14×width
Height= 9cm
Volume = 168cm³
Substitute into the formula
168 = 4w×9/3
36w = 168×3
36w = 504
w = 14cm
Hence the width of the pyramid is 14cm
Skyler getting a delivery from Chick-fil-A they charge $3 delivery fee plus $0.25 per mile write an equation to find the total cost y for a delivery that is X miles away
Answer:
y = 3 + 0.25x
Step-by-step explanation:
x represents the miles and if Skyler is charged $0.25 per mile, then x goes with the 0.25. The $3 is a flat fee and doesn't get added any more times then when it is first added.

How can I get equation x+4=-12 from equation x/4+1=-3
Answer:
All terms of the equation were divided by 4.
Step-by-step explanation:
When we are given a equation, it is possible to multiply or divided all of the terms of the equation by a factor.
In this question:
We are given:
[tex]x + 4 = -12[/tex]
And end up with:
[tex]\frac{x}{4} + 1 = -3[/tex]
Which means that all terms of the equation were divided by 4.

A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected
from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli with mean weight of 15.26 grams and standard deviation of 2.56 grams. The margin of error (ME) to construct a 99% confidence interval for the true mean amount of cheese filling is
A) 2.064 B) 1.432 C) 3.745 D) 1.276 E) 1.797
b. A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected
from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli and measure the weight of cheese filling. They find the 99% confidence interval of 14.16 to 15.84 grams. Which of the following is the correct interpretation?
I. We are 99% confident that the mean weight of cheese filling in all ravioli made by this process is between 14.16 and 15.84 grams.
II. 99% of all ravioli made by this process will have cheese filling weights between 14.16 and 15.84 grams.
III.We are 99% confident that the interval (14.16, 15.84) contains the mean weight of cheese filling in all ravioli made by this process.
IV. The weight of cheese filling in the ravioli is between 14.16 and 15.84 grams 99% of the time.
A) I only
B) III only
C)I and III.
D) II and III
E) I and IV
Answer: a. B) 1.432
b. E) I and IV
Step-by-step explanation:
a. Margin of error to construct a 99% confidence interval is calculated as
[tex]ME=t.\frac{s}{\sqrt{n}}[/tex]
where
t is the critical value expressed as t-score, which comes from t-distribution;
s is sample standard deviation
n is sample size
In this case, a t-score is used because the population standard deviation is unknown and the sample size is small, n < 30.
The way to find t-score is:
1) Define the degree of freedom, which is sample size minus 1: df = n - 1;
2) Compute alpha: [tex]\alpha=1-\frac{confidence}{100}[/tex];
3) Find the critical probability: [tex]p=1-\frac{\alpha}{2}[/tex]
With the df and critical probability, consulte the t-distribution table and find the score.
For the cheese filling:
df = 24
p = 0.995
t-score = 2.797
Calculating margin of error:
[tex]ME=2.797.\frac{2.56}{\sqrt{5}}[/tex]
ME = 1.432
The margin of error to construct a 99% confidence interval for the true mean amount of cheese filling is 1.432.
b. Confidence interval is an interval in which we have a percentage of certainty that the true population mean is. For example, with a 99% confidence interval of 14.16 to 15.84 grams, we are 99% confident that the true mean weight of cheese filling is between those numbers or that the weight of cheese filling is between 14.16 and 15.84 grams 99% of the time.
