Answer:
1 1/10 or 11/10
Step-by-step explanation:
Zane grew 3/5 of an inch during the first year and 1/2 an inch during the second. First, you have to make sure the denominators are the same number. Then, add the numerators. Simplify if needed.
Answer:
1.1 Inches
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. To get the common denominator I multiplied 3/5 by 2/2 to get 6/10 and I multiplied 1/2 by 5/5 to get 5/10 now that they have a common denominator you can add and you get 11/10 = 1.1
Helpppp Number 9 pleaseeeee
help again! algebra 1
Answer: maybe c?
Step-by-step explanation:
from eqn. 1
3x + 2y = 23
2y = 23 - 3x
y = 23/2 - 3/2x
sub into eqn. 2
1/2x - 4 = 23/2 - 3/2x
1/2x + 3/2x = 23/2 + 4/1
2x = 23/2 + 8/2
2x = 31/2
x = 31/4
sub into eqn. 1
31/4 + 2y = 23
2y = 23 - 31/4
2y = 92/4 - 31/4
2y = 61/4
y = 61/8 or 7 5/8
ummm i got something wrong but try c?
Answer:
C . 31/4,-1/8
Step-by-step explanation:
1. sub the given value of y
into 3x + 2 (1/2x -4) 23
2. slove for x = 31/4
3.sub the given value of x into 1/2x - 4 =y
4. solve the equation for y
5. y = -1/8
6. ordered pair to (x,y) = 31/4,1,8
simply (5^1/3)
A. 5^3
B. 1/5
C. 5
D. 5^9

Suppose x = 9 is a solution to the equation f(x) = g(x). If a table of values for the equation y = f(x) contains an x-value of 9 and a corresponding y-value of 18, then which of these statements is correct about a table of values for the equation y = g(x)?
A
If it contains an x-value of 9, the corresponding y-value must be 9.
B
If it contains an x-value of 9, the corresponding y-value must be 18.
C
If it contains a y-value of 18, the corresponding x-value must be 9.
D
If it contains a y-value of 18, the corresponding x-value must be 18.
Answer:
I think it may be A

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
The average rate of change on the given interval is 9/70
Step-by-step explanation:
Here, we are to find the average rate of change of the function on the given interval
We proceed as follows;
on an interval [a,b] , we can find the average rate of change using the formula;
f(b) - f(a)/b-a
From the question;
a = 0
b = 3
f(0) = -3/5
f(3) = -3/14
Substituting the values, we have;
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70
In a high school, 28% of the school’s population is seventeen years old. Of the students who are seventeen years old, 44% play a sport. One student at the high school is chosen at random to represent the school at a community event. What is the probability that the selected student will be seventeen years old and not play a sport?
Answer:
15.68%
Step-by-step
Since 44% of the 28% play sport subtract 44 from 100 to see how many of the 28% do not play sports and you get 56%. So multiply 56% and 28% and you get 15.68%.
Izinho do Shanghai Financial Center, o Jin Mao Tower é um imponente arranha-céu inaugurado em 1999. Com 88 andares (referência ao número oito, símbolo de sorte e prosperidade na cultura chinesa) e uma altura de 420 m, a torre tem um shopping, discotecas, bares, cafés, restaurantes, escritórios e o hotel Grand Hyatt. Suponha que uma réplica do Jin Mao Tower seja construída na razão de 1:80 e colocada em exposição no chão de um salão de 9 m de altura. A distância entre o topo dessa réplica e o teto desse salão será de
Answer:
[tex]3.75\ \text{m}[/tex]
Step-by-step explanation:
A escala da réplica é [tex]1:80[/tex]. Isso significa que 1 metro da réplica da escala representa 80 metros do edifício real.
Portanto, 1 metro do edifício real representa [tex]\dfrac{1}{80}[/tex] metros da réplica.
Precisamos encontrar a altura da réplica
[tex]420\ \text{m}=420\times\dfrac{1}{80}=5.25\ \text{m}[/tex]
Assim, a réplica da escala terá uma altura 5.25 m.
Está colocado numa sala com 9 m de altura.
A distância entre o topo da réplica e o teto do corredor é [tex]9-5.25=3.75\ \text{m}[/tex].

Three different coins are tossed. What is P(tail, head or tail, head, or tail)
Answers:
Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]
Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]
Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]
Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]
Step-by-step explanation (Read Carefully):
-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:
-A way to organize this is to have:
H = heads
T = tails
-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
Now, let’s apply some questions:
⇒ Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].
⇒ Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

Tina solved an equation incorrectly, as shown below:
Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Tina's solution?
Answer:
Step 2 should be division, not subtraction.
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
8x = 24
Step 2: Solve for x
Divide both sides by 8: x = 3We see that 8x is actually 8 times x. Therefore, we would need to use the Division Property of Equality to isolate x and get our answer.

SOMEONE HELP ASAP!!!!!
Answer:
A. y=[tex]\frac{3}{2}[/tex]x-3
B.y=[tex]\frac{-3}{4}[/tex]x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=[tex]\frac{3}{2}[/tex]x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=[tex]\frac{-3}{4}[/tex]x-3
pls help!!
A line is parallel to y = -3x + 2 and intersects the point (4,3). What is the equation of this parallel line?
y = [?]x + [ ]
Step-by-step explanation:
Parallel lines have the same slope so they can therefore never touch. Just change the y-int. (Any number as long as it's not the same as the previous)
