I ate twice as many apples as bananas and 3 times as many blueberries as bananas. If I
ate 12 fruits and berries altogether, how many apples did I eat? How many bananas?
How many blueberries?
Answer:
Below.
Step-by-step explanation:
Let the number of bananas I ate be x.
Number of apples = 2x.
Number of blueberries = 3x.
So we have the equation:
x + 2x +3x = 12
6x = 12
x = 2.
So I ate 2 bananas, 4 apples and 6 blueberries.
Answer:
4 apples 2 bananas and 6 blueberries

find the C.P if S.P= Rs 550, profit= 10%
Answer:
It's Rs. 500
Step-by-step explanation:
SP=CP +profit%of CP
or 550 = CP +10/100 CP
or 550= (100 CP +10 CP)/100
or 55000= 110CP
or CP = 55000/110
Hence, CP= 500

A tour company has a boat that sits at most 40 passengers. For a cruise on the Hudson River they charge $12 per adult and $5 per child. They will only take the boat out if they have sold at least $250 worth of tickets. Let a be the number of adults who take the cruise and c be the number of children. Will they take the boat out if they 14 adults and 9 children buy tickets? Justify.
Answer:
No
Step-by-step explanation:
For the adults:
$12 times the 14 adults which is: $168
Then for the kids:
$5 times the 9 kids which is: $45
Add next:
$168 plus the $45 equals $213
A(14)+b(5)=c
a sailor sights the top of a 200-foot cliff at a 17 degree angle of depression. how far is the boat from the base of the cliff
The boat is roughly 654ft away from the base of the cliff.
Step-by-step explanation:
We have the angle 17°
The side opposite the angle is 200ft.
We want to find the length of the adjacent side.
So what equation has Opposite and Adjacent in it?
Tangent. (Remember SOH-CAH-TOA)
Tan = opp/adj
Tan(theta°) = opp/adj
Rearranging,
adj = opp/tan(theta°)
adj = 200/tan(17°)
adj = 654.17ft
And to double check you answer,
° = tan^-1(opp/adj)
° = tan%-1(200/654)
° = 17°
What is the equation of the line that passes through (-5, 0) and (4, 3)?
Answer:
y = 1/3x + 5/3
Step-by-step explanation:
An equation contains a slope and y-intercept, in the form y = mx + b. To find the slope or m, you need to plug the coordinates into the slope formula.
y2 - y1/ x2 - 1
3 - 0/ 4 - (-5)
= 3 / 9
= 1/3
Now that we know the slope, we need to plug the values of x and y to find the y-intercept.
y = 1/3x + b
3 = 1/3(4) + b
3 = 4/3 + b
5/3 = b
The equation is y = 1/3x + 5/3

Answer:
Year(x) Predicted (ym) Residual(yd - ym)
1 39 0.135
2 49 -1.097
3 66 1.426
4 84 0.764
5 106 -1.292
Step-by-step explanation:
The formula for predicted (y_m) is given by the function;
f(x) = 30.151(1.289)^(x)
At x = 1;
y_m = 30.151(1.289)^(1)
y_m = 38.865
y_d - y_m = 39 - 38.865 = 0.135
At x = 2;
y_m = 30.151(1.289)^(2)
y_m = 50.097
y_d - y_m = 49 - 50.097 = -1.097
At x = 3;
y_m = 30.151(1.289)^(3)
y_m = 64.574
y_d - y_m = 66 - 64.574 = 1.426
At x = 4;
y_m = 30.151(1.289)^(4)
y_m = 83.236
y_d - y_m = 84 - 83.236 = 0.764
At x = 5;
y_m = 30.151(1.289)^(5)
y_m = 107.292
y_d - y_m = 106 - 107.292 = -1.292

3
(D)
Answer:
x = 5
y = -4/3
Step-by-step explanation:
2x + 3y = 6
x - 3y = 9
Substitution Method:
x = 3y + 9
2(3y+9) + 3y = 6
6y + 18 + 3y = 6
9y = -12
y = -12/9 or -4/3
x - 3(-4/3) = 9
x + 4 = 9
x = 5

What is the total number of digits required in numbering a book that has 1724 pages?
Answer:
5,789
Step-by-step explanation:
I got 5,789 because there are 9 one digit numbers. 1-9 -> 9x1=9. There are 90 two digit numbers. (10-99)-> 90x2=180. There are 900 three digit numbers. (100-999)-> 900x3=2700. There are 725 four digit numbers. (1000-1724)-> 724x4= 2900. Then, I added 9+180+2700+2900=5789.
In conclusion, the total number of digits required in numbering a book that has 1724 pages is 5789.
There are 5,789 digits in total required to number the pages of a book with 1,724 pages.
What is Numbering?A numbering is the assignment of natural numbers to a set of objects in some formal language, such as functions, rational numbers, graphs, or words, in computability theory.
Digits required in numbering a book that has 1724 pages?Given the total number of pages is 1,724
Let's break down the pages now to find the total digits.9
one-digit numbers (1-9) = 9 x 1 = 9 digits make up the number 1,724.90 numbers with two digits (10-99) = 90 x 2 = 180 digits900 three-digit numbers (from 100 to 999) = 900 times three = 2700 digits725 numbers with four digits (1000-1724) = 725 x 4 = 2900 digits
Let's add the digits now.9 + 180 + 2700 + 2900 = 5,789
As a result, the total number of digits required to number the pages of a 1,724-page book is 5,789.

Answer:
B = 44°
c = 27.8
b = 19.3
Step-by-step explanation:
m∡B = 180 - (90 + 46)
sin46° = 20/c
c = 20 / sin 46°
c = 27.8
b² + 20² = 27.8²
