Solve for X geometry
Answers
1. x=7
2. x=6
3. x=9
4. x=8
Explanations
1. This is an isosceles triangle because two angles are congruent. This also means the two sides are the same. This means 7 = x.
2. This is an equilateral triangle because all the angles are the same. Therefore, all sides are also the same. So x = 6.
3. This is also an equilateral triangle. We know this because all sides are the same. So from this we know that x-3 = 6. Solve the equation, and you'll find that x = 3.
4. This is also an isosceles triangle, because two of the angles are congruent. This means 2x-9 = 7. Solve this equation; x=8
Answer:
27) x = 7
28) x = 6
29) x = 9
30) x = 7
Step-by-step explanation:
I first added to two angles we already knew. Then, I took that number and subtracted it from the whole number in the algebraic equation. I then divided that number with the value paired with x to get x.
Sorry, it is hard to explain with words. Please give the person above me a reward. They answered before me.
I hope this helps you!

Q: The circle below has a circumference of 34.56 cm. Find the diameter.
Answer:
11cm = diameter.
c=circumference
d=diameter
π=3.14
r=half of diameter
34.56
C=2πr
d=2r
Solving for d (diameter)
d=C
π=34.56
π≈11.00079cm
rounded = 11cm!
You promised brainlest! Please!!
Step-by-step explanation:
Answer:
11.0008
Step-by-step explanation:
“Since we know circumference and diameter are related by π, we can use π to find diameter if we know circumference”
Equations:
C = πd
C/π = d
Therefore:
34.56 = pi(d)
34.56/3.14159265359 = 11.000789..........

Which statements are true for all rotations about the origin? Select all that apply.
Angles are taken to angles of the same measure.
Angles are taken to angles of the same measure.
Perpendicular lines are taken to perpendicular lines.
Perpendicular lines are taken to perpendicular lines.
Circles are taken to circles of the same center and radius.
Circles are taken to circles of the same center and radius.
Line segments are taken to line segments of the same length.
Line segments are taken to line segments of the same length.
Parallel lines are taken to parallel lines.
Answer:
Rotation about the origin only changes the coordinates but angle or segment measures remain same, therefore parallel and perpendicular lines stay as is.
Correct options:
Angles are taken to angles of the same measure.Perpendicular lines are taken to perpendicular lines.Line segments are taken to line segments of the same length.Parallel lines are taken to parallel lines.Second part to the worksheet

what is the y intercept of f(x)=(1/2)x?
Answer: C (0,1)
Step-by-step explanation:
The y intercept of a function is when it's x coordinate is zero, so input 0 into the function and solve for f(x)
f(0) = (1/2)^x
f(0) = (1/2)^0
f(0) = 1 Any number raised to zero is 1 so the y intercept has to be 1.
Suppose that the batting averages or AVG (hits per at-bat) of all players in the AAA baseball league are normally distributed with a mean of 0.2 and a standard deviation of 0.05. The middle 95% of the player will have a lower bound of:____.a. 0.19.b. 0.03.c. 0.30.d. 0.07.
Answer:
0.1
Step-by-step explanation:
Solving using empirical rule formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Hence, the lower bound 95% =
μ - 2σ
Mean = 0.2
Standard deviation of 0.05
= μ - 2σ
= 0.2 - 2(0.05)
= 0.2 - 0.1
= 0.1
The lower bound is 0.1

A cup slides off a 2.5 m high table with a speed of 2.8 m/s to the right. We can ignore air resistance. What was the cup's horizontal displacement during the fall?
Answer:
Horizontal distance = 1.98 m (Approx)
Step-by-step explanation:
Given:
Height = 2.5 m
Speed v = 2.8 m/s
Find:
Horizontal displacement
Computation:
s = ut + (1/2)gt²
2.5 = (1/2)(9.8)t²
t² = 0.5102
t = 0.7079 s
Horizontal distance = (v)(t)
Horizontal distance = (2.8)(0.7079)
Horizontal distance = 1.98 m (Approx)

Use the distributive property-
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
Answer:
Step-by-step explanation:
a) 3 - 4x = -7 - 4x
- 4x in both terms can be cancelled
3 = -7 ⇒ equation with no solution
b) 15 - 2x = -7x
15 = -5x
-3 = x
x = -3
c) 7 (y - 3) = 6y - 21
7y - 21 = 6y - 21
7y - 6y = -21 + 21
y = 0
1) Equation with no solution:
3x + 5 = 12 + 3x
there is no x that conforms that equation because the result is always 5 = 12, which is inconsistent
2) Equation with one solution
2y -5 = 7 ⇒ y = 12/2 ⇒ y = 6
3) Equation with infinite solutions
x - 10 = x - 3 - 7
Any value of x complies with this equation
How many strings of five English letters that start with two consecutive vowels (A,E,I,O, or U) have no repeated letters
Answer:
242880
Step-by-step explanation:
In the English alphabet, we have 5 vowels. To form a string of 5 English letters in which it starts with two consecutive vowels; then we have the following.
In the first space, 5 vowels are possible.
in the second space, 4 vowels are possible since there is no room for repetition of letters.
Now, the total number of ways of assigning two distinct vowels in the first two spaces = 5 × 4 = 20
From the question, since it is said that the letter starts with two consecutive vowels, it implies that starting from the third letter, it can be filled with all the remaining alphabet, be it a vowel or consonant.
Thus, the remaining alphabet = 26 - 2 = 24 alphabets to fill the 3 remaining spaces, which can be achieved in 24P3 ways.
P(24,3) = 24!/(24-3)!
P(24,3) = 24!/21!
P(24,3) = 24 × 23 × 22 × 21! / 21!
P(24,3) = 24 × 23 × 22
P(24,3) = 12144 ways
Thus, the total number of strings of five English letters that start with two consecutive vowels without having repeated letters is:
= 5 × 4 × 24 × 23 × 22
= 242880
5 4 24 23 22

equivalent fraction with the given denominator 45.
Answer:
1/5 = 2/10 = 3/15 = 4/20
= 5/25 = 6/30 = 7/35 = 8/40
= 9/45 = 10/50 = 11/55 = 12/60
= 13/65 = 14/70 = 15/75 = 16/80
= 17/85 = 18/90 = 19/95 = 20/100
= 21/105 = 22/110 = 23/115 = 24/120

= 29/145 = 30/150 = 31/155 = 32/160
= 33/165 = 34/170 = 35/175 = 36/180
= 37/185 = 38/190 = 39/195 = 40/200
= 41/205 = 42/210 = 43/215 = 44/220
= 45/225 = 46/230 = 47/235 = 48/240
= 49/245 = 50/250 = 51/255 = 52/260
= 53/265 = 54/270 = 55/275 = 56/280
= 57/285 = 58/290 = 59/295 = 60/300
= 61/305 = 62/310 = 63/315 = 64/320
= 65/325 = 66/330 = 67/335 = 68/340
= 69/345 = 70/350 = 71/355 = 72/360
= 73/365 = 74/370 = 75/375 = 76/380
= 77/385 = 78/390 = 79/395 = 80/400
