Answer:
b
Step-by-step explanation:
I would 100 because the more the trials means the more the results which means you get more of an accurate experiment then if you only did 10. Because since you have so many answers from all of the experiments you can conclude the correct answer from all of the experiments. I hope you get what I’m trying to say
It will take 4 months for sparky to reach 14 pounds. It is modeled by a linear function
Answer:
B
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides )
± 
= x
Change y back into terms of x, thus
(x) = ± 
three shapes. three areas to find. three areas to add together to find the whole area. gotcha.
Step-by-step explanation:
- smaller rectangle
- larger rectangle
- right triangle
<h2>
smaller rectangle: </h2>
length is 7 cm and width is 4 cm, so the area is <u>28 square cm</u>
<h2>
</h2><h2>
larger rectangle:</h2>
width is 4 cm and length is 10 cm, so the area is <u>40 square cm</u>
Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.
<h2>right triangle: </h2>
base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = <u>12 square cm</u>
With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).
Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.
<h2>weird shape's area from adding three shapes' areas: </h2>
28 + 40 + 12
= 80 square cm (ANSWER)
