math pls help i’ve been stuck on this for the longest
Basically it's almost everything but choice A
==================================================
Explanation:
When intersecting two lines to form an X shape, the vertical angles are the ones that form opposite one another. They do not have to align vertically, meaning they don't have to be stacked on top of one another. They could be side by side.
This applies to the following angle pairs
1 and 32 and 45 and 76 and 89 and 1110 and 1213 and 1514 and 16The items in bold apply to choices B through D
Side note: Vertical angles are always congruent.
Answer:
2nd, 3rd and 4th options
Step-by-step explanation:
when two lines intersect to make an X , angles on opposite sides of the X are called vertical angles. These angles are congruent.
from the listed angles the following are vertical angles.
∠ 5 and ∠ 7
∠ 3 and ∠ 1
∠ 4 and ∠ 2
Other vertical angles in the diagrm include
∠ 6 and ∠ 8
∠ 9 and ∠ 11

another question plssss
Answer:
(a) ∠1 and ∠5
Step-by-step explanation:
Complementary angles are angles whose measures total 90°. The angles do not have to be adjacent.
__
In this geometry, we can see that angles 1 and 2 are complementary, as are angles 4 and 5, since their respective sums are right angles. Angles 2 and 5 are vertical angles, so have the same measure.
∠1 + ∠2 = 90° . . . . . . adjacent angles that total a right angle
∠1 +∠5 = 90° . . . . . substitute ∠5 for ∠2, since measures are equal
This means angles 1 and 5 are complementary.

Answer:
2 = 22

5 = 13
6 = 10
Step-by-step explanation:
To help with future questions, take whatever is for the x and plug it into the equation
Answer:
22,19,13,10
Step-by-step explanation:
First, Replace the x in the equation with parenthesis (), then inside of the () put the x value in the table so it would look like: y=28-3(2). Then solve by multiplying 2 by 3 so you have y=28-6. Then just subtract 6 from 28 to get 22. Rinse and repeat for the rest of the values. Your first value will be 22, second 19, third 13, and lastly 10. Hope this helps!

Answer:
50 m
Step-by-step explanation:
We find the perimeter by adding all the sides of our figure.
The initial figure has perimeter :
P = 2 + 5 + 1 + 3 + 3 + 1 + 5
P = 20 m
The dilated figure with the scale factor of 2.5 has perimeter:
P = (2 + 5 + 1 + 3 + 3 + 1 + 5 ) · 2.5
P = 20 * 2.5 = 50 m

Answer:
[tex]\fbox{(a+b) and (a+b+1) are the factors}[/tex]
Step-by-step explanation:
Given equation = a² + 2ab + b² + a + b
Let's factorise,
We know that,
[tex]{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
Substituting the above factor in given equation,
[tex] {a}^{2} + 2ab + {b}^{2} + a + b = {(a + b)}^{2} + a + b \\ Taking \: (a+b) \: common \: in \: RHS \\ {a}^{2} + 2ab + {b}^{2} + a + b = (a + b)(a + b + 1) \\[/tex]

Please answer I am struggling
(For question 1 you have to do it yourself, get a ruler and measure the actual length of the drawing, then multiply it by 8 to get the actual dimensions in the exercise. )
Example, if you measure 4 inches, the actual dimension will be 4 x 8 = 32 ft
2. (Scale drawing 1:5 is that every 1 (length units) will be equal to 5(length units) in the actual dimensions)
Model : 3ft ; 7m
Actual : 15ft ; 35m (corresponding)
Actual : 20yd ; 12.5 cm
Model : 4yd ; 2.5 cm
6. 1.5 ft = 1.5 x 12 = 18 inches.
The model is 3 inches, and the actual rose is 18 inches -> The scale of the drawing is 6. (enlargement)
Same goes to the scale factor, but this time is the quotient of the corresponding side -> 3 : 18 = 1:6.
(If I got any parts wrong just tell me, I actually kinda forgot these kind of stuff)
The expression 11.5+ (4+ (-6.5)) is to be rewritten by applying the commutative
and associative properties of addition. If you use each property only one time,
which expression could be the result?
O (11.5+ (-6.5)) + 4
O 11.5+ (2.5)
O (4+ (-6.5)) +11.5
O (11.5 + 4) + (-6.5)
Answer:
C. [tex](4+ (-6.5)) +11.5[/tex]
Step-by-step explanation:
Just exchange:
11.5 + (4 + ( - 6.5 ) )
⇒ (4+ (-6.5)) +11.5
After applying the property the expression would be (4+ (-6.5)) +11.5.
What is Associative property?Changes to the order of the addends have no effect on the sum, according to the associative feature of addition.
For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) or (2 + 3) + 4
Given:
11.5+ (4+ (-6.5))
In Above case we can use the Associative property over addition.
For this we just need to exchange the position of number along with their signs.
So, 11.5+ (4+ (-6.5))
= (4+ (-6.5)) +11.5
Hence, after applying the property the expression would be (4+ (-6.5)) +11.5.

Jill usually rides her bike at a speed of 10 miles per hour. Let x represent the hours and y represent miles. Write an equation that shows the relationship between x and y.
Answer:
y = 10x
Step-by-step explanation:
If x represents the hours & y represents the miles, your equation should be in multiplication.
10 miles an hour would be 10x and y would be the total. You can also plug in the answer to check. Let's say x is 2. Plug that into 10x and you get 10(2) = 20 and since y is 20, that'd be 20 miles. Therefore, you'd be running 20 miles in 2 hours, which makes sense because your rate is 10 miles an hour.
Alex is playing a game
where he gets 8 points
8
every time his ball hits the
target. He gets an extra 8
points every time his ball
hits the target 8 times in a
row. How many points will
Brady receive if he hits the
target 8 times in a row?
Answer:
72 points
Something important to note is that 8 is the constant,If you can get 8 each time that would be the same as doing 8+8+8...
If he hits it 8 times in a row, that means the constant was being multiplied 8 times, 8+8+8+8+8+8+8+8=64The problem also states that if he hits it 8 times in a row you add 8 more points.
64+8=72
Therefore, the answer is 72There are 72 points Brady receive if he hits the target 8 times in a row.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Alex is playing a game where he gets 8 points 8 every time his ball hits the target.
And, He gets an extra 8 points every time his ball hits the target 8 times in a row.
Hence, Number of points Brady receive if he hits the target 8 times in a row is,
⇒ 8 x 8 + 8
⇒ 64 + 8
⇒ 72
Thus, There are 72 points Brady receive if he hits the target 8 times in a row.
