Step-by-step explanation:
A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. If Erica has at most $10 to spend on the cab ride, how far could she travel? Write an inequality expression that represents the situation and solve! Explain your reasoning! You can copy/paste the needed symbols as needed: ≥ ≤
Answer:
The inequality expression would be 1.75+0.65x ≥10
She would be able to ride ~12.7 miles or just 12 miles rounding down.
Step-by-step explanation:
Following mx+b, the m value would be 0.65 because it is added per mile.
The 1.75 would be the b value because it is the starting value.
So the equation would look like 1.75+0.65x. To know if the 10 value would be less than or more than, we have to know if 10 is the limit value or starting value. Because 10 is our limit value, we will use greater than or equal to.
To know how many miles Erica could travel, we would have to subtract 1.75
from 10. We would get 8.25. We would then divide 8.25 by 0.65. so the number of miles she can travel is ~12.7 miles or just 12 miles rounding down.
What do you call raising a base to the exponent 2?
Answer:
When exponents are raised to another exponent, the exponents are multiplied. (a m) n = a (m × n) EX: (2 2) 4 = 4 4 = 256 (2 2) 4 = 2 (2 × 4) = 2 8 = 256

A flash disk has the capacity of storing 1 megabyte of data. How many kilobytes of data can be stored in the same flash disk
For this sort of problem, you need to be familiar with prefixes.
So:
megabyte = [tex]1 *10^6[/tex] bytes
kilobyte = [tex]1*10^3[/tex] bytes
and a regular byte would just be [tex]1[/tex]
Now, you will need to do a conversion:
[tex]1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}[/tex]
I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are [tex]1*10^6[/tex] bytes!)
In the second fraction thought, remember one kilobyte is [tex]1*10^3[/tex] bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do [tex]\frac{1kilobyte}{1*10^3bytes}[/tex], but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
[tex]10^3[/tex] kilobytes (1000 kilobytes)
Hope this helped!

Mike is planting flowers in plastic cups for his science fair project. Each of the cups is filled to the top with a mixture of soil, fertilizer, mulch, and sand in different proportions. Each cup contains 1/2 cup of soil, 1/3 cup of fertilizer, and 1/8 cup of mulch. How much sand should he use to fill the cup?
PLZ HURRY
Answer:
He will need 1/8 of sand to fill the cup
Step-by-step explanation:
For 1/2 i filled half of the cup for 1/3 i made new cup split it in 3 and added it in main cup then for 1/8 made a new cup split it in 8 and added it to main cup the test is sand.

Rewrite y - 3 = -9(x - 1) in standard form.
Answer:
9x + y = 12
Step-by-step explanation:
Hi there!
We are given the equation y - 3 = -9(x-1) and we want to write it in standard form
The equation is currently in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1 , y_1)[/tex] is a point and m is the slope. Standard form is ax + by = c, where a, b, and c are free integer coefficients
We can first convert the equation from point-slope form into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We can distribute 9 to every term on the right side:
y - 3 = -9x + 9
Now add 3 to both sides
y = -9x + 12
Now the equation is in slope-intercept form (y=mx+b). To make it standard form, add 9x to both sides, to make the form ax + by = c .
9x + y = 12
Hope this helps!

Find the mean rounded to the nearest tenth median mode and range 59,50,54,50,50
Answer:
Mean = 52.6
Median = 50
Mode = 50
Range = 9
Step-by-step explanation:
How to find the mean
The mean of a set of numbers is the sum divided by the number of terms.You add 59,50,54,50,50 then divide it by 5 because there are 5 numbersHow to find the median
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.How to find the mode
The mode is the element that occurs most in the data set. In this case, 50 occurs 3 times.How to find the range
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 59 − 50 = 9Hope this helps

Answer:
Step-by-step explanation:
1) Apples : Mangoes = 20 : 10 = 2 :1
2) Ponkans : Guavas = 15 : 30 = 1 : 2
3) Apples : Mangoes : Guavas = 20 : 10 : 30: = 2 : 1 : 3
4) All fruits = apples + mangoes + ponkans + guavas = 20 + 10 + 15 + 30 = 75
All fruits : Apples = 75 : 20 = 15 : 4
4) apples + guavas = 20 + 30 = 40
Mangoes + Ponkans = 10 + 15 = 25
apples + guavas : mangoes + Ponkans = 40 : 25 = 8 : 5
