Find the area of the triangle below.

1 answer:

Answer:

20

Step-by-step explanation:

Since this is not a right angle, we can use the formula $Area= Sin(y) (\frac{1}{2}ab)$

a=7

b=10

y=35

So, when we plug these values in, we get:

$a=Sin(35)(\frac{(10)(7)}{2})\\\\=35sin(35)\\=20.075\\$

rounded to the nearest hundredth, I believe it's 20.

Which of the rectangles below have an area of 18 cm²?

Elenna [48]

$\textsf{Rectangle A}$

$\implies \mathsf {Area = 3 \times 6 = 18cm^{2}}$

$\implies \bf {Yes}$

$\textsf {Rectangle B}$

$\implies \mathsf {Area = 2 \times 9 = 18cm^{2}}$

$\implies \bf {Yes}$

$\textsf {Rectangle C}$

$\implies \mathsf {Area = 5 \times 4 = 20cm^{2}}$

$\textsf {Rectangle D}$

$\implies \mathsf {Area = 9 \times 2 = 18cm^{2}}$

$\implies \bf {Yes}$

Hector is dividing students into groups for an HR wants to divide the boys and girls so that each group has the same number of t

Roman55 [17]

Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be $x$

and total hikers in one group be $y$

if number of girls and boys in every group is same, then

$\frac{21}{x} + \frac{56}{x} = y$

$\frac{21 + 56}{x} = y\\x*y = 77$ ....(1)

from (1) $x$ will either be 11 or 7

for $x = 11$ the values won't be real.

For $x = 7\\y = \frac{77}{7} \\y = 11$

so there will be 7 groups with 11 hikers in each groups and every group will have $\frac{21}{7} = 3$ boys and $\frac{56}{7} = 8$ girls
