Answer:
17 singles24 doubles11 triplesStep-by-step explanation:
Let s, d, t represent the numbers of singe, double, and triple cones sold. The problem statement tells us three relationships.
s + d + t = 52 . . . . . . Danielle sold 52 cones one day
d -2t = 2 . . . . . . . doubles is 2 more than twice the number of triples
0.89s +1.19d +1.39t = 58.98 . . . . total amount of sales
__
There are many ways to solve this set of equations. A graphing calculator can quickly tell you the solution is ...
(s, d, t) = (17, 24, 11)
__
If you want to solve this by hand, it may work well to use substitution.
The second equation gives an expression for d:
d = 2t +2
The first equation gives an expression for s that can be written in terms of t.
s = 52 -d -t
s = 52 -(2t +2) -t = 50 -3t
Using these in the last equation, we have ...
0.89(50 -3t) +1.19(2t +2) +1.39t = 58.98
1.10t = 12.10 . . . . . . . . collect terms, subtract 46.88
t = 11 . . . . . . . . . . . . . . divide by 1.10
d = 2(11) +2 = 24
s = 50 -3(11) = 17
Danielle sold 17 singles, 24 doubles, and 11 triple cones.

Answer:
The slope of line is 9
Step-by-step explanation:
We can use two pairs of input-output from the table to find the slope of the given line. Here x is input and y is output.
Slope is defined as the steepness of a line and is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Selected pairs from table are:
(-1,-18) and (0,-9)
Here
[tex]x_1 = -1\\x_2 = 0\\y_1 = -18\\y_2 = -9[/tex]
Putting the values in the formula
[tex]m = \frac{-9-(-18)}{0-(-1)}\\=\frac{-9+18}{0+1}\\= 9[/tex]
Hence,
The slope of line is 9

what is the coordinates of the point where y-4x=1 crosses the y-axis
Answer:
(0, 1)
Step-by-step explanation:
you have to put the equation in the slope point form
y=mx+b and here b is the y-intercept (where it crosses the y axis)
y-4x=1 add 4x to both sides
y=4x+1 so the coordinats are (x=0, y=1)

HELPPPPPP MEEEE!! A deep-sea diver found an amazing reef 15 kilometers below sea level. What integer would represent this situation
Answer:
-15
Step-by-step explanation:
Sea-level can be seen as 0 on a number line. The Diver is going below the sea-level, so think of this as him going below the number zero, into the negatives. He is going down 15km, so -15km would represent the integer (whole number) that you're looking for.

Solve formula as indicated. - F = m + 2a for a
Answer:
The value of 'a' will be:
[tex]a\:=\:-\frac{f}{2}+-\frac{1}{2}m[/tex]
Step-by-step explanation:
Given the formula
[tex]-F = m+2a[/tex]
Let us solve the equation for 'a'
[tex]-F = m+2a[/tex]
Flip the equation
[tex]2a+m=-f[/tex]
Add -m to both sides
[tex]2a+m+(-m)=-f+(-m)[/tex]
[tex]2a = -f - m[/tex]
Divide both sides by 2
[tex]\frac{2a}{2}=\:\:\frac{-f\:-\:m}{2}[/tex]
[tex]a\:=\:-\frac{f}{2}+-\frac{1}{2}m[/tex]
Therefore, the value of 'a' will be:
[tex]a\:=\:-\frac{f}{2}+-\frac{1}{2}m[/tex]

Prove that: 6^7-6^6+6^5 is divisible by 31
15 points!!!
Step-by-step explanation:
[tex]6^7-6^6+6^5=6^{5+2}-6^{5+1}+6^5\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=6^5\cdot6^2-6^5\cdot6^1+6^5\\\\\text{use the distributive property}\ a(b+c)=ab+ac\\\\=6^5\cdot(6^2-6^1+1)=6^5\cdot(36-6+1)=6^5\cdot31\\\\6^7-6^6+6^5=6^5\cdot31[/tex]
therefore it's divisible by 31
[tex](6^7-6^6+6^5):31=(6^5\cdot31):31=6^5[/tex]
[tex]6^7 - 6^6 + 6^5[/tex] is divisible by 31.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
[tex]6^7 - 6^6 + 6^5[/tex] s
Taking common factors.
[tex]6^5[/tex] (6² - 6 + 1)
[tex]6^5[/tex] (36 - 6 + 1)
[tex]6^5[/tex] x 31
This is divisible by 31.
Thus,
[tex]6^7 - 6^6 + 6^5[/tex] is divisible by 31.

On the farms the hens brooded, but no chicks hatched. The farmers complained that they were unable to raise any pigs—the litters were small and the young survived only a few days. The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.

Sam is reading a book. He finishes 6 pages of the book in 18 minutes. How many pages would Sam have finished reading in 36 minutes?
Answer:
12 pages
Step-by-step explanation:
This is a fairly straight forward question.
Sam read 6 pages in 18 minutes, and we want to know how many pages he could have finished if he read for 36 minutes.
36 minutes is double the time of 18 minutes.
So we just have to double the 6 pages Sam read into 12 pages and that is the answer.

Answer: 67.8%
Step-by-step explanation:
The variables that are at most 11 will lie on the left of 11.
The percentage of the possible observations to the left will be:
= 1 - percentage to the right
= 1 - 0.322
= 0.678
= 67.8%
