Answer:

Hello! answer: 16

Step-by-step explanation:

These are a bit different instead your solving for B so you have to work backwords so... 20 × 20 = 400 12 × 12 = 144 400 - 144 = 256 now we just find out what multiplied by itself = 256 16 × 16 = 256 therefore b = 16 Hope that helps!

last year 1/5 of the students in your class played a sport this year 10 students join the class five of the new students play a

tino4ka555 [31]

Answer:

Step-by-step explanation:

last year 1/5 of the class played sports, so s = (1/5) c

the next year, s increased by 5, c increased by 10 and the fraction changed to 1/4, so for the next year (s+5) = (1/4)(c+10)

To solve this we can substitute s = (1/5)c from the first equation into the second, so

((1/5)c + 5)=(1/4)(c+10), simplify both sides

(1/5)c + 5 = (1/4)c + 10/4, simplify 10/4 to 5/2

(1/5)c + 5 = (1/4)c + 5/2, multiply both sides by 20 to eliminate fractions (least common multiple of 2, 4 and 5)

4c + 100 = 5c + 50, subtract 4c, subtract 50 from both sides

50 = c, number of students in class last year was 50, this year is 10 more, so this year is 60

Please answer the question!

ANSWER

$Area = 2\sqrt{3} \: {cm}^{2}$

EXPLANATION

We need to use the Pythagoras Theorem to find the height of the triangle.

${a}^{2} + {b}^{2} = {c}^{2}$

$({2 \sqrt{3}) }^{2} + {b}^{2} = {4}^{2}$

$12 + {b}^{2} = 16$

${b}^{2} = 16 - 12$

${b}^{2} = 4$

Take positive square root to get;

$b = \sqrt{4} = 2$

Area =½bh

$Area = \frac{1}{2} \times 2\sqrt{3} \times 2$

$Area = 2\sqrt{3} \: {cm}^{2}$
