Find the Value of “Y”.
Answer:
26
Step-by-step explanation:
7x - 28 = 5x + 12 and 5x + 12 + y = 180
The angle (7y - 28) and angle y are supplementary angles which means their sum is 180°
7y - 28 + y = 180 add like terms
8y - 28 = 180 add 28 to both sides
8y = 208 divide both sides by 8
y = 26
A car traveled 63 miles on 3 gallons of gas. What proportion can you set up to determine how many miles, m, the car can travel on 7 gallons of gas? 63 7 7 63 ECO II 63 = 3
Answer: With 7 gallons of gas, the car can travel 147 miles.
The proportion is:
N*(63 miles/3) = total distance the car can travel with N gallons of gas.
Step-by-step explanation:
We know that with 3 gallons of gas, the car can travel 63 miles.
Then for N gallons of gas, we first need to count the number of times that 3 is in N.
This is equal to the quotient between N and 3:
N/3
This is the number of times that we have 3 gallons of gas, in a total of N gallons of gas.
And for each one of these, the car can travel 63 miles.
Then the total distance that the car can travel with N gallons of gas is:
(N/3)*63 miles. = N*(63 miles/3) = total distance the car can travel.
In this case, we want to know how many miles the car can travel with 7 gallons of gas, then if we use that equation we get:
(7/3)*63 miles = 147 miles.
A chocolate chip cookie recipe calls for 2 cups of chocolate chips for every 3 3/4
cups of flour. How much flour would you use if you only had 1 cup of chocolate
chips?
9514 1404 393
Answer:
1 7/8 cups flour
Step-by-step explanation:
Half the quantity of chocolate chips will call for half the quantity of flour:
(3 3/4 cups)/2 = (15/4 cups)/2 = 15/8 cups = 1 7/8 cups of flour
1: The temperature is -2
∘C
. If the temperature rises by 15
∘C
, what is the new temperature? (Draw a number line to help)- The temperature is -2 c. If the temperature rises by 15 c, what is the new temperature? Answer {You would do 15c takeaway -2c This would equal to the new temperature as being 13c.}
2: At midnight the temperature is - 6
∘C
. At midday the temperature is 9
∘C
. By how much did the temperature rise? (Draw a number line to help)- 15° Celcius {You can add from -6 +1 till you get to 0 then add the rest of the numbers and it will exactly be 15.}
3:Draw a number line to help you with what the final temperature is.
Then write an addition expression that represents the final temperature.
(Hint: Start temp + movement amount = final temperature )
The temperature was and then fell .

This question is incomplete, the complete question is;
Consider a set of data in which the sample mean is 73.4 and the sample standard deviation is 4.9. Calculate the z-score given that x = 69.5.
Round your answer to two decimal places.
Answer: the z-score is -0.80
Step-by-step explanation:
Given that;
mean μ = 73.4
standard deviation σ = 4.9
x = 69.5
z-score = ?
z = (x - μ) / σ
we substitute
z = (69.5 - 73.4) / 4.9
z = -3.9 / 4.9
z = - 0.7959 ≈ -0.80 { 2 decimal places }
Therefore, the z-score is -0.80

Tina is going for a bike ride. When she leaves her house, she starts pedaling and her speed steadily increases. As she approaches the stop sign at the end of her street, she slows down at a steady pace until she comes to a complete stop. After waiting at the stop sign for her turn to go, she starts pedaling again and her speed steadily increases at a slower pace than when she first left her house. She reaches a comfortable speed and rides at this speed until she approaches another stop sign, causing her to steadily slow down until she again comes to a complete stop.

Answer:

Step-by-step explanation:
A and B are sets of real numbers defined as follows.A= {z│z > 4}B= {z│z ≤ 9}Write A U B and A ∩ B using interval notation. If the set is empty, write Ø
Answer:
[tex]AnB=(5,6,7,8,9)[/tex]
[tex](AUB)=(5,\infty) U (-\infty,9)[/tex]
Step-by-step explanation:
From the question we are told that
A= {z│z > 4}
B= {z│z ≤ 9}
Generally A&B are assumed to be really integers
therefore
A={5,6,7,8,.....}={z│z > 4}
B=(9,8,7,6.....)={z│z ≤ 9}
a)For [tex]AnB[/tex]
Mathematically the [tex]AnB[/tex] is given as
[tex]AnB[/tex]=[tex]A=(5,6,7,8,9,10......) n B=(9,8,7,6,5,4,3,2,1......)[/tex]
[tex]AnB[/tex]=(5,6,7,8,9)
Therefore the intercept [tex]AnB[/tex] is Given as
[tex]AnB=(5,6,7,8,9)[/tex]
b) for [tex]AuB[/tex]
Mathematically the [tex]AuB[/tex] is given as
[tex]AuB[/tex]=[tex]A=(5,6,7,8,9,10......) U B=(9,8,7,6,5,4,3,2,1......)[/tex]
[tex]AuB[/tex]= [tex](5,\infty) U (-\infty,9)[/tex]
Therefore the union [tex]AuB[/tex] i given as
[tex]AuB[/tex]= [tex](5,\infty) U (-\infty,9)[/tex]
