Answer:
The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.
Step-by-step explanation:
5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.
25 + 144 = 169.
13 ^ 2 = 169.
Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.
Given:
Sides of triangle= 5cm, 13cm and 12cm
To find: Whether a triangle is a right angled triangle.
This can be solved by applying Pythagorean theorem:
According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
[tex]H^2=P^2+B^2[/tex]
where,
H= Hypotenuse
P= Perpendicular
B=Base
Applying given values in the formula:
[tex]H^2=P^2+B^2\\\\13^2=5^2+12^2\\\\169=25+144\\\\169=169[/tex]
Since, R.H.S= L.H.S
Thus, we can say that this triangle is a right angled triangle.

The figure below is a rectangular box in which EFGH and ABCD are rectangles and BF is perpendicular to planes EFGH and ABCD. Use the figure to complete parys a through e.
Answer:
Step-by-step explanation:
Given question is incomplete: Find the compete question in the attachment.
a). Skew lines neither the parallel lines nor they intersect each other.
Two pairs of skew lines are BF and EH, & CG and EF.
b). Since EFGH and ABCD are rectangular planes and BF and DH are perpendicular to them,so both will be the altitudes between the planes.
Therefore, BF and DH will pe parallel.
c). BD and DH are the diagonals of the planes parallel to each other.
Therefore, BD and DH will be parallel.
d). Since BD and plane EFG don't intersect each other, so the solution will be an empty set.
e). HG is perpendicular to DH. So,the planes BDH and FHG containing these lines will be perpendicular to each other.

Answer:
C) If the area of a square is an odd perfect square, the perimeter of the square will be even.
Step-by-step explanation:
Just did it on edge.
Option 3 - If the area of a square is an odd perfect square, the perimeter of the square will be even is correct.
We have the statements given in the question.
We have to investigate the conclusion that can be drawn using the law of syllogism.
What is Law of Syllogism ?The Law of Syllogism says that if the following two statements are true:
→ If p, then q.
→ If q, then r.
Then, the following statement is also true -
→ If p, then r.
According to the question, we have -
→ P(If the area of a square is an odd perfect square) ,Q(then the side length of the square will be odd).
→ Q(If the side length of the square is odd), R(then the perimeter of the square will be even).
Now, in the above statements, q is true for p and r is true for q.
Therefore, Option 3 is correct.

Answer:
Length of DE = 22.8cm
Step-by-step explanation:
Given: 23° and 8.9cm
To find the length of DE, we need to use the SOH-CAH-TOA method.
Since DE is the hypotenuse (The longest side), we need to use SOH meaning sinФ([tex]\frac{opposite}{hypotenuse}[/tex]).
The opposite of the angle, 23° is 8.9cm, by replacing the formula with the given, we would get the following: sin(23°)=([tex]\frac{8.9}{x}[/tex]).
To calculate, we need to multiply 'x' to both sides: x*sin(23°) = 8.9
Using a calculator, sin(23°) is 0.39
0.39x = 8.9
By dividing 0.39 to both sides, we should end up with 22.8cm (rounded to the nearest tenth of a centimeter).

One month Jane rented 4 movies and 8 video games for a total of $49. The next month she rented 2 movies and 3 video games for a total of $19. Find the
rental cost for each movie and each video game,
Answer:
movie costs $1.25
Video game costs $5.50
Step-by-step explanation:
4x + 8y = 49 , 2x +3y = 19. By solving for x first, we get x=5/4. After substituting x into the equation, we get 4(5/4) + 8y =49 , 2(5/4)+3y=19 and then we solve for y. and we get y=11/2. check our answer, and it is true.

What are the intercepts of y=8x-18
Answer:
[tex]x-intercept=\frac{9}{4}[/tex]
[tex]y-intercept=-18[/tex]
Step-by-step explanation:
The y-intercept is where x is equal to 0, and the x-intercept is where y is equal to 0, so:
[tex]x-intercept=(x,0)\\y-intercept=(0,y)[/tex]
The equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept, so the y-intercept is -18.
Now set the value of y to 0 to find the intercept of x:
[tex]0=8x-18[/tex]
Solve for x. Add 18 to both sides:
[tex]0+18=8x-18+18\\18=8x[/tex]
Divide both sides by 8:
[tex]\frac{18}{8}=\frac{8x}{8} \\\\\frac{18}{8} =\frac{9}{4}\\ \\x=\frac{9}{4}[/tex]
The x -intercept is [tex]\frac{9}{4}[/tex].
[tex]x-intercept=(\frac{9}{4},0)\\\\y-intercept=(0,-18)[/tex]
:Done
Step-by-step explanation:
Step 1: Find the y-intercept
To find the y-intercept, you need to set the x-value to 0 and solve for y.
[tex]y = 8(0) - 18[/tex]
[tex]y = 0 - 18[/tex]
[tex]y = -18[/tex]
[tex](0, -18)[/tex] ← y-int
Step 2: Find the x-intercept
To find the x-intercept, you need to set the y-value to 0 and solve for x.
[tex]0 + 18 = 8x - 18 + 18[/tex]
[tex]18 / 8 = 8x / 8[/tex]
[tex]2.25 = x[/tex]
[tex](2.25, 0)[/tex] ← x-int
WHOEVER EXPLAINS ALL THEIR WORK AND GOES THROW EAXH STEP WILL GET BRAINLEST THAT IS COMPLETELY FINISEHD. write the equation of the line that goes through the points (3,2) (4,-1) show ALL steps and EXPLAIN what you are doing in each step. you will be graded on showing all the steps and your explanation.
Answer:
[tex]y = -3x+11[/tex]
Step-by-step explanation:
I accept your challenge!
First we know that a equation of the line is a linear equation, and its equation is:
[tex]y = mx+b[/tex]
[tex]m: \text{slope}\\b: \text{y-intercept}[/tex]
In this context, the slope, defined as the steepness of a line is characterized as the ratio of RISE (the difference in the y-coordinates, the vertical change) over the RUN (the difference in x-coordinates, the horizontal change).
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} $[/tex]
Once we know two points where the line goes through, we can get the slope, once we know the change in y and x.
I will take [tex](3,2)[/tex] as Point 1 and [tex](4,-1)[/tex] as Point 2.
So, [tex]x_{1}=3 \text{ and } y_{1}=2\\x_{2}=4 \text{ and } y_{2}=-1[/tex]
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{-1-2}{4-3} $[/tex]
[tex]$m=\frac{-3}{1}=-3 $[/tex]
Now we have to find the y-intercept:
To do so, think about the the points given and the nearly finished equation, we can find b with those two informations.
Our currently equation of the line is:
[tex]y = -3x+b[/tex]
Using the points, take Point 1 as an example, it says that when [tex]x = 3, y = 2[/tex], so plugging it in the equation:
[tex]2 = -3(3)+b\\2 = -9+b\\11 = b[/tex]
Taking the Point 2
[tex]-1 = -3(4)+b\\-1 = -12+b\\11 = b[/tex]
Now we found [tex]b[/tex]! The equation is complete!
[tex]y = -3x+11[/tex]

оооо
O c. 12
OD. 152
Answer:
8.5
Step-by-step explanation:
it would technically round to 9, but given the answer choices its A) 8
The protein in the bag of dog food is 8 pounds.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Weight of the bag = 35 pounds
Percentage of the weight of protein = 23%
The weight of the protein in the bag.
= 23% of 35 pounds
= 23/100 x 35
= 8.05 pounds
= 8 pounds
Thus,
The weight of the protein is 8 pounds.

OC. $88,000 sxs $112.000
OD
$22,000 sxs $28,000
Answer:
$24,890.46, $25,109.59
Step-by-step explanation:
Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)
Answer: $24,890.46, $25,109.54

Step-by-step explanation:
two consecutive integers have a sum of 51 . find the integers
First represent your two consecutive integers as follows.
X ⇒ first integer
X + 1 ⇒ second integer
Since their sum is 51, our equation reads x + x + 1 = 51.
Now combine like terms to get 2x + 1 = 51.
Now subtract 1 to isolate the 2x and this gives us 2x = 50.
Since 2 is being multiplied by x, to get x by itself, we need
to divide by 2 on both sides of the equation to get x = 25.
If x = 25, then x + 1 would be 25 + 1 or 26.
So our two consecutive integers are 25 and 26.
