Answer: The answer for this question would be answer choice B "(0, 10) and (1, 15)". (0, 10) represents her starting amount and week saved, and (1, 15) would represent her saving for one week and having $15 total.
Hope this helps!
Given:
A spinner is divided into 8 equal sections where 3 are black, 4 are yellow, and 1 is red.
To find:
The probability of it landing either on a yellow or a red section.
Solution:
We have,
Total number of sections = 8
Black sections = 3
Yellow sections = 4
Red sections = 1
Now,
Either yellow or red sections = 4 + 1
= 5
Now, the probability of it landing either on a yellow or a red section is:


Therefore, the required probability is
.
Answer:
D
Step-by-step explanation:
Exponential equation takes the form
where
a is the initial value ( a ≠ 0), and
b is the base ( b ≠ 1)
The equation given can be written as
. Thus, it is an exponential equation.
So a = 1 and b = 3.1
Thus we can say that the initial value = 1 and the base is 3.3
700<=560+0.08x
x is total sales $
the 560 is the constant weekly pay, since we're only calculating for one week.
we're adding 0.08x to account for the 8% of the total sales
solve it for x:
700-560 <= 0.08x
140 <= 0.08x
1750 <= x
or x >= 1750
meaning she needs $1750 worth of sales that week to earn atleast $700
as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
Let’s solve this step by step. :)
First, let’s assign variables for the missing number: x and y.
so the 3 numbers would be x, y and 28
then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81
Using the first equation, we can get x = 61-28 = 33
Using the 2nd equation, we can get y = 76-28 = 48
then, we can verify if our answer is right by substituting these values in the 3rd equation:
x + y = 81
33 + 48 = 81
81 = 81 ✔️
So the 3 numbers are 28, 33 and 48.
