Answer:
Step-by-step explanation:
We have the equation:
we know that:
14*14 = 196
then:
14 = √196
Now, we can rewrite:
50 = 2*25
98 = 2*49
This is because we know that 49 and 25 are perfect squares, then:
Now we can use the common factor √2 and get:
and we know that:
7*7 = 49
5*5 = 25
then:
the value of b is:
b = 12
You can solve the by dividing the change in y by the change in x. the answer should be D
Answer: Third picture:
* 14 eggs
* 700 g of sugar
* 525 mL of oil
* 1400 g of banana
* 2380 g of fluor
* 105 mg of baking soda
Solution:
Using rule of three
4 eggs for 10 people
x eggs for 35 people
x=4*(35/10)→x=4*(3.5)→x=14 eggs
Similarly with the others ingredients:
Sugar=(200 g)*3.5→Sugar=700 g
Oil=(150 mL)*3.5→Oil 525 mL
Banana=(400 g)*3.5→Banana=1400 g
Flour=(680 g)*3.5→Flour=2380 g
Baking soda=(30 mg)*3.5→Baking soda=105 mg
I think the answer is A.
the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.
The answer is 4 i hope this helps
