Answer:
126.4 cm
Step-by-step explanation:
1. 15.8 * 3 = 47.4 (This is the length)
2. Find half of the rectangle
47.4 + 15.8 (width) = 63.2
3. Find the whole perimeter
63.2 * 2 = 126.4
Answer:
126.4
Step-by-step explanation:
If you put three squares that are all 15.8cm together, you get a rectangle that is 47.4cm by 15.8cm. To get 47.4, you multiply 15.8 x 3 because it's three 15.8 squares together. Then to find the perimeter of the rectangle, you add all the sides together to get the answer 126.4.

Answer: see proof below
Step-by-step explanation:
Use the following Half-Angle Identities: tan (A/2) = (sinA)/(1 + cosA)
cot (A/2) = (sinA)/(1 - cosA)
Use the Pythagorean Identity: cos²A + sin²B = 1
Use Unit Circle to evaluate: cos 45° = sin 45° = [tex]\frac{\sqrt2}{2}[/tex]
Proof LHS → RHS
Given: [tex]cot\ (22\frac{1}{2})^o-tan\ (22\frac{1}{2})^o[/tex]
Rewrite Fraction: [tex]cot\ (\frac{45}{2})^o-tan\ (\frac{45}{2})^o[/tex]
Half-Angle Identity: [tex]\dfrac{sin(45)^o}{1-cos(45)^o}-\dfrac{sin(45)^o}{1+cos(45)^o}[/tex]
Substitute: [tex]\dfrac{\frac{\sqrt2}{2}}{1-\frac{\sqrt2}{2}}-\dfrac{\frac{\sqrt2}{2}}{1+\frac{\sqrt2}{2}}[/tex]
Simplify: [tex]\dfrac{\frac{\sqrt2}{2}}{\frac{2-\sqrt2}{2}}-\dfrac{\frac{\sqrt2}{2}}{\frac{2+\sqrt2}{2}}[/tex]
[tex]=\dfrac{\sqrt2}{2-\sqrt2}-\dfrac{\sqrt2}{2+\sqrt2}[/tex]
[tex]=\dfrac{\sqrt2}{2-\sqrt2}\bigg(\dfrac{2+\sqrt2}{2+\sqrt2}\bigg)-\dfrac{\sqrt2}{2+\sqrt2}\bigg(\dfrac{2-\sqrt2}{2-\sqrt2}\bigg)[/tex]
[tex]=\dfrac{2\sqrt2+2}{4-2}-\dfrac{2\sqrt2-2}{4-2}[/tex]
[tex]=\dfrac{4}{2}[/tex]

Answer:
0.5 m³
Step-by-step explanation:
You have a rectangular prism and a cube. Find the volume of each separately. After solving, add the two volumes together to find the total volume.
Cube
The side length is 0.5 m.
V = a³
V = (0.5 m)³
V = 0.125 m³
Rectangular Prism
The height is 0.75 m, the width is 0.5 m, the length is 1 m.
V = lwh
V = (0.75 m)(0.5 m)(1 m)
V = 0.375 m³
0.125 m³ + 0.375 m³ = 0.5 m³
Circle A has center of (4, 6) and a radius of 5, and circle B has a center of (1, 0) and a radius of 15. What steps will hemp show that circle A is similar to circle B?
A. Dilate circle A by a scale factor of 3.
B. Translate circle A using the rule (x - 3, y + 6).
C. Rotate circle A 180 About the center.
D. Reflect circle A over the y-axis.
Answer:
The correct option is;
A Dilate circle A by a scale factor of 3
Step-by-step explanation:
The given parameters are;
The center of circle A is (4, 6)
The radius of circle A = 5
The center of circle B = (1, 0)
The radius of circle B = 15
Therefore, circle A is similar to circle B and is equivalent to circle B, scaled down by a factor of 3
Radius of circle A = 5,
Radius of circle B = 15 = 3 × 5
Therefore, the scale factor for the dilation (transformation) of circle A to circle B is 3.
For a circle to be similar dilate circle A by a scale factor of 3
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
The given parameters are;
The centre of circle A is (4, 6)The radius of circle A = 5The center of circle B = (1, 0)The radius of circle B = 15Therefore, circle A is similar to circle B and is equivalent to circle B, scaled down by a factor of 3
The radius of circle A = 5,
Radius of circle B = 15 = 3 × 5
Therefore, the scale factor for the dilation (transformation) of circle A to circle B is 3.

Kyle challenges you to a game. Each player rolls a standard number cube twice. If the sum of the results is divisible by 3, you win. If it is not, Kyle wins. What is your probability of winning? Is this a fair game?
Answer:
The probability of you winning is 1/3
No, it is not a fair game
Step-by-step explanation:
The first thing we need to have here is the sample space. This refers to the set of all possible results that can occur from the rolling.
Please check attachment for this
Kindly note that the total number of possible outcomes is 36.
And in the attachment, sums which are divisible by 3 are circled.
The number of circles we can count is 12
Thus, the probability of you winning would be number of circles/total number of outcomes = 12/36 = 1/3
Is it a fair game?
No, it is not
It can only be a fair game if the probability of winning equals probability of losing ( which is 18/36 = 1/2 or 0.5)

Complete Question
Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3 cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Answer:
[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]
Step-by-step explanation:
Given
[tex]Flower\ Pot = 9 in^3[/tex]
[tex]Small\ Bag = 2\frac{2}{3} in^3[/tex]
Required
How many bag of soil can fill the flower pot
To solve this,we simply divide the volume of flower pots by the small bags. This is done as follows;
[tex]Number\ of\ Bags = \frac{Flower\ Pot}{Small\ Bag}[/tex]
[tex]Number\ of\ Bags = \frac{9 in^3}{2\frac{2}{3} in^3}[/tex]
Convert fraction
[tex]Number\ of\ Bags= \frac{9 in^3}{\frac{8}{3} in^3}[/tex]
[tex]Number\ of\ Bags = 9 in^3/\frac{8}{3} in^3[/tex]
[tex]Number\ of\ Bags = 9 * \frac{3}{8}[/tex]
[tex]Number\ of\ Bags = \frac{9 * 3}{8}[/tex]
[tex]Number\ of\ Bags = \frac{27}{8}[/tex]
[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]
Hence, the number of bags needed is [tex]3\frac{3}{8}[/tex]

Mike is buying a box of juice pouches. Flav-O-Squeeze costs $5.88 for 12 pouches. Turbo Taste costs $10.20 for 20 pouches. How much more does Turbo Taste cost per pouch?
Answer:
2 cents
Step-by-step explanation:
you would just divide the Flav-O-Squeeze price by 12 since there are 12 pouches and the Turbo Taste price by 20 since there are 20 pouches and then you would get 1 pack of Flav-O-Squeeze is 49 cents and 1 pack of Turbo Taste is 51 cents and if you subtract them Turbo Taste is 2 cents more then Flav-O-Squeeze
The cost of Turbo Taste per pouch is $0.02.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mike is buying a box of juice pouches. Flav-O-Squeeze costs $5.88 for 12 pouches. Turbo Taste costs $10.20 for 20 pouches.
The more cost will be calculated as,
Cost of Turbo Taste = 10.20 / 20 = $0.51
The cost of Flate-O-Squeeze = 5.88 / 12 = $0.49
The more cost of Turbo-Taste = 0.51 - 0.49
The more cost of Turbo-Taste = $0.02
Therefore, the cost of Turbo Taste per pouch is $0.02.

An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.
What is a sample?A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.
Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.
Hence, the correct option is 85,000.

Find the measure of AB¯¯¯¯¯¯¯¯. A. 14 B. 22 C. 21 D. 20
Answer:
C. 21
Step-by-step explanation:
We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:
BC * AC = DC * EC
Here:
AC = AB + BC = (2x + 5) + 9 = 2x + 14
BC = 9
DC = 10
EC = KC = (1 + 2x) + 10 = 2x + 11
So plug all these in:
BC * AC = DC * EC
9 * (2x + 14) = 10 * (2x + 11)
18x + 126 = 20x + 110
2x = 126 - 110 = 16
x = 8
Put this back into the expression for AB:
AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21
The answer is thus C.

In baseball, the equation E=9R/I a pitcher's earned run average E, where R is the number of earned runs the player allowed and I is the number of innings pitched. Last season, a pitcher had an earned run average of 2.80 and allowed 70 earned runs. How many innings did the pitcher pitch last season?
Answer:
The innings pitched last season is 225.
Step-by-step explanation:
Given that,
Earned run average = 2.80
Allowed earned run = 70
The given equation is
[tex]E=\dfrac{9R}{I}[/tex]
We need to calculate the innings pitched last season
Using given equation
[tex]E=\dfrac{9R}{I}[/tex]
[tex]I=\dfrac{9R}{E}[/tex]
Where, E = earned run
R = allowed earned run
I = innings pitch
Put the value into the formula
[tex]I=\dfrac{9\times70}{2.80}[/tex]
[tex]I=225[/tex]
Hence, The innings pitched last season is 225.
