harriet is making loaves of bread for her grandmothers bakery. she has 12 1/2 cups of flour. the recipe calls for 5 1/2 cups of flour to make 3 loaves of bread. which equation can be used to find L, the total number of loaves of bread harriet can make
A 12 1/2 x 5 1/2 = L/3
B 12 1/2 divided by 5 1/2 = L/3
C 12 1/2 + L/3 = 5 1/2
D 12 1/2 - L/3 = 5 1/2
9514 1404 393
Answer:
B 12 1/2 divided by 5 1/2 = L/3
Step-by-step explanation:
The proportion ...
(recipe flour)/(recipe loaves) = (available flour)/(available loaves)
can be rearranged to ...
(available flour)/(recipe flour) = (available loaves)/(recipe loaves)
(12 1/2) / (5 1/2) = L / 3 . . . . . . matches choice B
A line passes through a point (8, 2) and has a slope of 3/2
Answer:
y = 3/2x - 10
Step-by-step explanation:
The equation :
y - y1 = m(x - x1)
y - 2 = 3/2(x - 8)
y - 2 = 3/2x - 12
y = 3/2x - 12 + 2
y = 3/2x - 10a data survey representative calls phone numbers selected at tandom until someone answers. each call has a .22 probability of someone answering it. let N be the number of calls until someone answers.
What type of variable is N?
Binomial, geometric or neither?
Since the number of trials is not fixed, N is neither a binomial or a geometric variable, it is an inverse binomial variable.
The sample is chosen at random, hence, the trials are independent, that is, each person has the same probability of answering it, hence N is not a geometric variable.
For it to be a binomial distribution, there needs to be a fixed number of trials, which there is not, hence, N is also not a binomial variable.
The distribution that counts the number of trials until x successes in the inverse binomial distribution, which means that N is an inverse binomial variable.A similar problem is given at https://brainly.com/question/25644451

Answer:
m∠XYW = 32°, m∠WYZ= 85°
Step-by-step explanation:
6x+44-10x+65=117
-4x+109=117
-4x=117-109
=8
x=-8÷4
=-2
Hence, ∠XYW = (6x+44)°
= [6(-2)+44]°
= (-12+44)°
= 32°
Hence, ∠WYZ = 117° - 32°
= 85°

5x -25 =105 fin the value of x
Answer:
26
Step-by-step explanation:
5(26)-25
5*26=130
130-25=105
Answer:
To find the value, isolate x.
5x - 25 = 105
Add 25 to both sides.
5x = 130
Divide both sides by 5.
x = 26

A. Only A
B. Only B
C. Both
D. Neither
Answer:
A. Only A
Step-by-step explanation:
Lets take a look at Sequence A first. By translating triangle MNO along line segment NB, MNO's top left corner is now on point B, but the shape and orientation have not changed. Then, when we reflect MNO over the vertical line that goes through B, we "flip" MNO onto ABC exactly.
So Sequence A DOES map MNO onto ABC
Now let's take a look at Sequence B to see if it works too. First, we reflect, or "flip" triangle MNO over the vertical line that passes through points M and O. Now MNO and ABC have the same orientation or shape, but aren't in the same location. Next, Sequence B tells us to translate MNO along line segment MB. This puts point M on point B, resulting in the two triangles next to each other and in the same orientation, touching at point B, but not mapped onto one another.
So the answer is choice A: Only A maps MNO onto ABC

31. The sum of two consecutive numbers is 45. Find the numbers.
Step-by-step explanation:
U1 + U2 = 45
x + (x + 1) = 45
2x = 45 - 1
2x = 44
x = 44/2
x = 22
U1 = x
U1 = 22
U2 = x + 1
U2 = 22 + 1
U2 = 23
Number = 22 and 23

Answer:
218
-72
12° C
Step-by-step explanation:
The magnitude of a single number is the positive version of that number.
We write it mathematically like this:
|−218|=218
|-12|=12
The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.
For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.
1 Solve the system of equations by the substitution method. 5x+10y = 30 4x + 8y = 36 Select the correct choice below and fill in any answer boxes within your choice. A. The solution is (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions: {(x,y)|5x + 10y = 30} or {(x,y)|4x + 8y = 36}. C. There is no solution: Tor .
The system of equations:
5x + 10y = 30
4x + 8y = 36
Has no solutions, the correct option is C.
How to solve the system of equations?Here we have the system of equations:
5x + 10y = 30
4x + 8y = 36
We want to use the substitution method, then we need to isolate one of the variables. Let's work with the second equation:
4x + 8y = 36
Divide by 4:
x + 2y = 9
x = 9 - 2y
Now replace that in the other equation to get:
5*(9 - 2y) + 10y = 30
45 - 10y + 10y = 30
45 = 30
This is a false equation, thus, the system has no solutions.

elena, karla and feye are playing a card game where they score points. karla scores twice the number of points elena foes and faye scores 30 points more then elena does. the sum of their three scores is 114 . who scores more points
Answer:
faye
Step-by-step explanation:
okay so
114-30=84
25% of 84 = 21
21 is how much elena has
21 x 2 = 42
42 is how much karla has
21 + 30 = 51
51 is how much faye has
42 + 21 = 63
63 + 51 = 114
so therefore faye has the most
Callie got 37 pieces of Halloween candy. Her brother got 42 pieces. She wants to estimate to find about how many pieces of candy they have together. What should her first step be?
Answer:
Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen. Then count each stash separately. Put the candies in groups of 10 to quickly establish that over 70 pieces were collected. Callie should steal a stack from her brother's pile while he's not looking. Just calmly shift one stack of ten candies to her side. She should announce she got 47 pieces and her brother only 32.
