Step-by-step explanation:
6x-15+2x^2-5x
2x^2+x-15
Formula :
Base²= Hypotenuse² - Perpendicular ²
Remember the a² in formula has nothing to do with the a we have to find. :)
The formula for a triangle:
Base times height divided by 2
Equation Form:
b×h÷2
Answer:
Step-by-step explanation:
No of students study math = 3/5 of 50 = 30
No of students study English = 3/10 of 50 = 15
Total = 30 + 15 = 45
Remaining students = 5
No of students study geography = 5
Fraction of geography to whole class = 5/45 = 9
Answer:
Step-by-step explanation:
A recipe uses 214 cups of flour for a batch of cookies. Henry makes 10 batches of cookies for a bake sale.
A model shows a total of c cups divided into 10 sections, each labeled 2 and 1 fourth.
Part A
Which equation models the total number of cups of flour, c, Henry needs?
c+214=10
214×c=10
10+c=214
214×10=c
Part B
How many cups of flour does Henry need?
2014cups
2212cups
2434cups
2512cups
Part C
Estimate how much flour Henry would need to make 15 batches of cookies. Explain.
I would round 214 to 2, so Henry would need about 30 cups of flour.
I would round 214 to 3, so Henry would need about 45 cups of flour.
I would round 214 to 1, so Henry would need about 15 cups of flour.
I would round 214 to 234, so Henry would need about 30 cups of flour.
