Two given angles cannot be both...
A. congruent and complementary
B. vertical and congruent
C. adjacent and congruent
D. vertical and adjacent
Please help
Answer:
D
Step-by-step explanation:
It d because D is for dogs
Two given angles cannot be both vertical and adjacent which is the correct answer would be option (D)
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
When two angles are congruent, or equal in size, and they are immediately opposite one another, they are said to be vertical.
Vertical angles do not share a common side, but rather a common vertex or point.
A vertex and a common side are shared by adjacent angles.
Since vertical angles can not have a common side when they are immediately opposite one another, two given angles cannot be both vertical and adjacent.
Hence, the correct answer would be option (D)

A cat chased after a dog for l mile, and then stop to rest. As soon as the cat sotped,the dog chased after the cat for 1500 yard back towards their starting point. How many yards were the ainmals for her starting point?
Answer:
0.14768 mile
Step-by-step explanation:
Given that:
Distance at which cat chased dog = 1 mile ; hence they've moved 1 mile from their starting position
Distance for. Which dog chased cat =. 1500 yards towards starting position
Converting miles to yards
1 mile = 1760 yards
1 yard = 0.000568 mile
Number of miles the animals are from Their starting position :
1760 yards - 1500 yards = 260 yards
260 * 0.000568 = 0.14768 mile

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees Fahrenheit and C is degrees Celsius. What is the temperature (in degrees Fahrenheit) of water that is 10 degrees Celsius?
Answer:
The temperature is [tex]50^{\circ}F[/tex]
Step-by-step explanation:
Given
[tex]F= (C*1.8) + 32[/tex]
Required
Find F when [tex]C = 10[/tex]
[tex]F= (C*1.8) + 32[/tex]
Substitute 10 for C
[tex]F = 10 * 1.8 + 32[/tex]
[tex]F = 18 + 32[/tex]
[tex]F = 50[/tex]

The right side is labeled (2 x + 4) inches. Complete the steps to find an expression that represents the perimeter of the rectangle. Substitute the expressions for length and width into the formula 2l + 2w. Distribute 2 to each term in the parentheses. Combine like terms. inches
Answer:
1.) 2(8x-1)+2(2x+4)
2.) 16x-2+4x+8
3.) (20x+6)
Step-by-step explanation:
The perimeter of the rectangle is (20x + 6)inches
The perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed as:
P = 2l + 2w
Given that;
l = 8x - 1
w = 2x + 4
Susbtitute
P = 2(8x - 1) + 2(2x + 4)
Expand
P = 2(8x) - 2(1) + 2(2x) + 2(4)
P = 16x - 2 + 4x + 8
P = 16x + 4x - 2 + 8
P = 20x + 6
Hence the perimeter of the rectangle is (20x + 6)inches

when 2(3/5 x + 2/3 y - 1/4 x -1 1/2 y + 3 )is simplified, what is the resulting expression?
Answer:
Simplifying the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]
Step-by-step explanation:
We need to simplify the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]
First we will solve terms inside the bracket
[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]
Converting mixed fraction [tex]1\frac{1}{2} y[/tex] into improper fraction, we get: [tex]\frac{3}{2}y[/tex]
Replacing the term:
[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-\frac{3}{2}y +3)[/tex]
Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket
[tex]2(\frac{3}{5}x\times60+\frac{2}{3}y\times60-\frac{1}{4}x\times60-\frac{3}{2}y\times60 +3\times60)\\2(3x\times12+2y\times20-1x\times15-3x\times30-3\times60)\\2(36x+40y-15x-90y-180)[/tex]
Now, combine like terms
[tex]2(36x-15x-90y+40y-180)\\2(21x-50y-180)[/tex]
Now, multiply all terms with 2
[tex]42x-100y-360[/tex]
So, Simplifying the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]
The length of a rectangle is 1 7/9 in and its width is 3/4 of its length. Find the area of this rectangle.
Answer:
The answer is 4/3 or 1.33 square units.
Step-by-step explanation:
Length = 1 + 7/9 = 16/9 units.
Width = 3/4 units.
Since area of rectangle = Length * Width
Area = 16/9 * 3/4 = 4/3 square units.

Step-by-step explanation:
Notice that:
15x = 5 * 3x and 10y = 5 * 2y.
Since there is a common factor of 5,
we can take out the factor.
=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).

Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because . Does Noah's method always work? Explain why or why not.
Answer:
Yes Noah's method will always work
Step-by-step explanation:
Noah's method states that:
To find 20% of a number he divides the number by 5. For example, 20% of 60 is 12.
Noah's method will always work because:
20% = 20/100
Simplifying 20/100 to the least fraction = 20/100 = 1/5
20% of x = 1/5 × x
= x/5 = x ÷ 5
Applying this to the examples
20% of 60 = 1/5 × 60
= 60/5 = 12.
Therefore, Noah's method will always work.

Step-by-step explanation:
Math problem\James and lucas committed in a climbing competition and coming back down. James climbed at the average 3 mph and came back down at 4 mph. Lucas climb at the average of 2 mph and came back down at 5 mph. If the path from the bottom to the top was 2 miles how much time did it take for both friends to finish and who was faster.
Answer:
1.166666 ; 1.4 ; James
Step-by-step explanation:
Given that:
Path from bottom to top = distance = 2 miles
Time taken = distance /speed
James :
To climb up:
Time = 2 / 3 = 2/3 hours
Coming down :
Time = 2 / 4 = 1/2 hours
Total time taken = 2/3 + 1/2 = 1.166666 hours
1.166666 * 60 = 70 minutes
Lucas :
To climb up:
Time = 2 / 2 = 1 hour
Coming down :
Time = 2 / 5 = 2/5 hours
Total time taken = 2/3 + 1/2 = 1.4 hours
1.4 * 60 = 84 minutes
James was faster :
1.166666 < 1.4
