Kenny wants to buy 2 kilograms of hamburger buns and 2 kilograms of wheat rolls. How much will he spend? spelt rolls
$5.83/kilogram hot dog buns
$7.92/kilogram hamburger buns
$8.46/kilogram wheat rolls
$5.74/kilogram English muffins
Answer:
He will spend $32.76
Step-by-step explanation:
$7.92 * 2 kilograms = $15.84 (This is how much is spent on hamburger buns)
$8.46 * 2 kilograms = $16.92 (This is how much is spent on wheat rolls)
$15.84+$16.92 = $32.76 (This is the total amount spent)
Solve this equation: –3(x – 14) + 9x = 6x + 42
Answer:
0
Step-by-step explanation:
Step 1 - Expand bracket:
[tex]-3(x - 14) + 9x = 6x + 42\\-3(x) + -3(-14) + 9x = 6x + 42\\-3x + 42 + 9x = 6x + 42[/tex]
Step 2 - Combine like terms:
[tex]-3x + 42 + 9x = 6x + 42\\42 + 6x = 6x + 42[/tex]
As both sides are the same, the equation equals 0.
[tex]42 + 6x = 6x + 42\\42 - 42 = 6x + 42 - 4x\\6x = 6x\\6x - 6x = 6x - 6x \\0 = 0\\[/tex]
Hope this helps!

A. Double bar graph
B. Line graph
C. Histogram
D. Double line graph
The type of graph that would be the most appropriate for Rick to use would be the line graph. That is option B.
What is a graph?A graph is defined as the representation of data on two lines that intercepted on an y and x axis which is used for easy interpretation of results obtained from a data set.
The different types of graph include the following;
Double bar graph,Line graph andDouble line graph.
The line graph is used for the representation of data taken for a short period of time that appears to have little to no difference.
The difference between the temperature of the different days analysed is limited therefore a line graph can be used.

Which BEST explains the expression x( y z + 1 2 )? A) x depends on ( y z + 1 2 ). B) ( y z + 1 2 ) depends on x. C) x and ( y z + 1 2 ) are dependent on each other. D) x and ( y z + 1 2 ) are independent of each other.
9514 1404 393
Answer:
D) x and ( y z + 1 2 ) are independent of each other
Step-by-step explanation:
Assuming this is not intended to be describing a function named x with an argument of yz+12, the variables in any expression are assumed to be independent of each other, unless additional information is provided showing their dependencies.
Here, there is no such additional information, so we must assume ...
x and (yz +12) are independent of each other
_____
Additional comment
The assumption stated in the answer is intended to ensure we're not concerned with something of the form ...
g(x)
which is an expression saying 'g' is dependent on 'x'. If we know 'g' is a function name, then g(yz+12) will make 'g' be dependent on (yz+12).
Similarly, if x(a) is intended to mean that x is a function of 'a', then the corresponding x(yz+12) will mean that x is dependent on (yz+12). This would be quite unusual, since letters toward the end of the alphabet are usually used for variable names, while letters in the middle of the alphabet are used for function names.
The following function gives the population of a town, with t measured in years after 2010. What will the population of the town be in 2019? Round to the nearest whole number.
P(t)=7842e0.018t
Answer:
Solution
verified
Verified by Toppr
It is given that
Present population (P) = 15625
Rate of increase (r) = 4% p.a.
Period (n) = 3 years
We know that
Population after 3 years = P(1+r/100)
n
Substituting the values
= 15625(1+4/100)
3
By further calculation
= 15625×26/25×26/25×26/25
=17576
So the increase = 17576−15625=1951

On a bicycle, Jack can travel 20 miles in 4 hours. How many miles did he travel in one hours?
Answer:
Jack traveled 5 miles in 1 hour
Step-by-step explanation:
Answer: In one hour Jack can Travel 5 miles.
Step-by-step explanation:
Jack can travel 20 miles in 4 hours. So to find out how many miles Jack can travel in 1 hour, we need to divide the number of miles for 4 hours (which is 20) by 4.
20 miles ÷ 4 hours = 5 miles in 1 hour
Therefore, we can say Jack can travel 5 miles in 1 hour.

The total simple interest on $1600 invested for five years is $224. What is the percentage rate per annum?
Answer:
The percentage rate per annum is 2.8%
Step-by-step explanation:
We need to multiply the principal by the time, then divide the interest by the product of P×T, so:
1,600 × 5 = 8,000
224 ÷ 8,000 = 0.028
Then we convert our final product to a percentage.
0.028 to a percent is 2.8%
