Answer:
X= 12
Y= -1
Step-by-step explanation:
Answer:
x=12, y=-1
Step-by-step explanation:
[x-2y=14, x=-3y+9]
[3y+9-2y=14]
simplify
[-5y+9=14]
isolate y for -5y+9=14: y=-1
For x=-3y+9, substitute y=-1
x=-3(-1)+9=12
x=12

Define the following sequence recursively
11,33,55,77
Answer:
Step-by-step explanation:
Recursive sequences generally look like this:
a1 = something
an= ahhhhhh
The 1st term in this sequence is 11.
So we have
a1=11
And now we see that each term is adding by 22.
We have,
a1=11

Angle A is circumscribed about circle O.
What is the measure of angle O?
[picture below]
Answer:
134°
Step-by-step explanation:
[tex] In\: \odot O,[/tex] AB and AC are tangents at points B and C respectively. OB and OC are radii.
[tex] \therefore OB\perp AB\: \&\: OC\perp AC[/tex]
(By tangent radius theorem)
[tex] \therefore m\angle ABO =m\angle ACO = 90\degree [/tex]
[tex] m\angle CAB+ m\angle ABO +m\angle ACO+ m\angle BOC = 360\degree [/tex]
[tex]\therefore 46\degree + 90\degree +90\degree+ m\angle BOC = 360\degree [/tex]
[tex]\therefore 226\degree + m\angle BOC = 360\degree [/tex]
[tex]\therefore m\angle BOC = 360\degree-226\degree [/tex]
[tex]\therefore m\angle BOC = 134\degree [/tex]
[tex]\implies m\angle O= 134\degree [/tex]
At a local seaside, a vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50. The vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. For the afternoon he expects to sell no more than 50 ice-creams.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.
Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:
0 < x ≤ 70, 0 < y ≤ 45 (1)
The vendor expects to sell no more than 50 ice creams, hence:
x + y ≤ 50
Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)
Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:
Revenue = 3x + 4.5y
At the point (5, 45), the revenue is:
Revenue = 3(5) + 4.5(45) = $217.5

Answer:
y = 19.4
x = 14.1
Step-by-step explanation:
(Finding y);
Sin(54) = [tex]\frac{y}{24}[/tex]
Sin(54) * 24 = y
19.4 = y(Finding x);
Cos(54) = [tex]\frac{x}{24}[/tex]

What is the surface area of a cylinder with base radius 222 and height 555? Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
28pi square units
Step-by-step explanation:
khan academy bae
Answer:
20π cubic units
Step-by-step explanation:
The volume of a cylinder is the area of the base x height.
The area of a circle is π r^2 squared.
So the area of the base is π ⋅ 2^2 = 4π
The height of the cylinder is 5, so the volume is 4π ⋅ 5 = 20π cubic units
What is the slope of the line that
passes through these two points?
(-2, 4)
(3, 4)
Remember, given two points (19) Slopes
run (22)
Simplify your answer completely.
Answer:
0
Step-by-step explanation:
Use the formula y2-y1/x2-x1. The two points are (-2,4) and (3,4) This will make the equation 4-4/-2-3. This simplifies to 0/-5. This is equal to 0. Therefore, the slope is 0.
If this has helped you please mark as brainliest
The slope of the line that passes through these two points (-2, 4) and (3, 4) will be 0.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
Slope = Rise / Run
Slope = (y₂ - y₁) / (x₂ - x₁)
Then the slope of the line that passes through these two points (-2, 4) and (3, 4) will be
Slope = (4 - 4) / (3 - (-2))
Slope = 0 / 5
Slope = 0

y = x2 + 5x – 9
y = 2x + 1

Which statement is true?
Answer:
The standard deviation for week two was about 3 ounces more than the standard deviation for week one
Step-by-step explanation:
Given
[tex]Week\ 1: 128, 105, 80, 82, 96, 98, 87, 100, 112, 126[/tex]

See attachment for options
Required
The true statement
Checking the standard deviation
For week 1
Calculate the mean:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{128+ 105+ 80+ 82+ 96+ 98+ 87+ 100+ 112+ 126}{10}[/tex]
[tex]\bar x = \frac{1014}{10}[/tex]
[tex]\bar x_1 = 101.4[/tex]
Then standard deviation
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{(128 - 101.4)^2 +............+ (126- 101.4)^2}{10}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{2522.4}{10}}[/tex]
[tex]\sigma_1 = \sqrt{252.24[/tex]
[tex]\sigma_1 = 15.88[/tex]
For week 2, we have:
[tex]\bar x = \frac{75+ 85+ 90+ 97+ 89+ 105+ 110+ 127+ 129+ 130}{10}[/tex]
[tex]\bar x = \frac{1037}{10}[/tex]
[tex]\bar x_2 = 103.7[/tex]
Then standard deviation
[tex]\sigma_2 = \sqrt{\frac{(75 - 103.7)^2 +................+ (130- 103.7)^2}{10}}[/tex]
[tex]\sigma_2 = \sqrt{\frac{3538.1}{10}}[/tex]
[tex]\sigma_2 = \sqrt{353.81[/tex]
[tex]\sigma_2 = 18.81[/tex]
Compare the standard deviations
[tex]\sigma_1 = 15.88[/tex]
[tex]\sigma_2 = 18.81[/tex]
Calculate the difference:
[tex]d = \sigma_2 - \sigma_1[/tex]
[tex]d = 18.81 - 15.88[/tex]
[tex]d = 2.93[/tex]
[tex]d \approx 3[/tex]

Tommy had 40 oranges to give to 3 groups of children.
- The first group ate 30% of the total oranges.
- The second group ate 7 of the total oranges.
- The third group ate 1/8 of the total oranges.
How many oranges were left?
Answer:
16
Step-by-step explanation:
1st group = 30% or .3 as a decimal
.3 * 40 = 12
2nd group = ate 7
Third group = 1/8 or .125 as a decimal
.125 * 20 = 5
12 + 7 + 5 = 24
40 -24 = 16

You roll a standard number cube 7 times Assume that each number is equally likely to come up each time you roll To the nearest tenth of a percent the probability that number less than 3 comes up exactly 4 of the 7 times
Answer:
0.4%
Step-by-step explanation:
If we are looking to have a number less than 3 rolled 4 out of 7 times.
Our winning numbers are 1 and 2. Our losing numbers are 3, 4, 5, and 6.
This means that our winning percentage is 33.3% and our losing percentage is 66.6%.
We need to multiply these numbers together taking our number of rolls into account.
.333 * .333 * .333 * .333 * .666 * .666 * .666 = 0.0036
