A group of people attempt to bake the largest vegan cake the used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. How many kilograms of cocoa powder and dates do they use?
Answer: 187 kilogram
Step-by-step explanation:
Let the kilogram of dates be represented by x.
Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:
= 1/10 × x = 17
0.1x = 17
x = 17/0.1
x = 170 kilogram
Date = 170 kilogram.
Cocoa powder = 17 kilogram
The total kilogram of date and cocoa powder used will be:
= 170 + 17
= 187 kilogram
Find the slope of y-intercept of the line represented by the table. Please look at the photo
Answer:
The slope is m= 4 and the y intercept is b= 9
Step-by-step explanation:
The slope is found by using change in y over change in x, or rise over run. From the table, this means, how much does y change for every time x goes up. As you can see, every time x increases by one, y increases by 4. So that´s your slope. The y intercept is when the line crosses the y axis, where x=0. Because you already know the slope, and that when x is one, y is 13, all you have to do is to know that going backwards by one for x means going backwards by 4 for y, and 13-4 is 9.
a line that includes the point (5, 1)and has a slope of 1
What is the value of x in the equation 3/4 x + 24 = x − 12 ?
Answer:
x = 144
Step-by-step explanation:
3/4x + 24 = x - 12
3/4x - x = -12 - 24
3/4x - 4/4x = -36
-1/4x = -36
x = -36/-1/4
x = 144

Step-by-step explanation:
Marco is interested in the number of penguins who live on a particular ice floe. He decides to take an aerial photo of
the floe and create a 20 by 20 grid on the photo. He randomly selects 3 cells and counts the number of penguins in
each. He then finds the mean number of penguins for those 3 cells. Marco repeats this process for a total of 50
samples and makes a dotplot of the 50 means. This graph is an approximation of
O stratified random sampling.

2(y + 3) + 2(4 - y) HELP ME
Answer:
14
Step-by-step explanation:
1. Distribute
2(y + 3) + 2(4 - y)
2 + 6 + 2(4 − )
2. Rearange terms
2y + 6 + 2(4 - y)
2 + 6 + 2(- + 4)
3. Distribute
2y + 6 + 2(-y - 4)
2y + 6 - 2y + 8
4. Add numbers
2y + 6 - 2y + 8
2y + 14 - 2y
5. Combine like terms
2y + 14 - 2y

can i be brainiest...
Answer:
the answer is 14y
Step-by-step explanation:
this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.
find the simple interest on each amount 1500 at 11% for two years
Answer:
330.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 11%/100 = 0.11 per year,
then, solving our equation
I = 1500 × 0.11 × 2 = 330
I = $ 330.00
The simple interest accumulated
on a principal of $ 1,500.00
at a rate of 11% per year
for 2 years is $ 330.00.

Mrs. brown has 8 more boys than girls in her class and has a total of 26 students. Determine how many girls and boys are in the class.
May I please get some help ASAP?
Answer:
There are 9 girls in the class and 17 boys in the class
Step-by-step explanation:
Set up a system of equations where b is the number of boys and g is the number of girls
b + g = 26
b = g + 8
Solve by substitution by substituting g + 8 as b into the top equation
b + g = 26
(g + 8) + g = 26
2g + 8 = 26
2g = 18
g = 9
So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:
9 + 8
= 17
So, there are 17 boys.
There are 9 girls in the class and 17 boys in the class.
