Answer:

36

Step-by-step explanation:

The answer is easy to find if we use the cross-multiplication method.

We know 7 students out of 10 picked apples, then 3 out of 10 picked bananas.

We know the number of people who picked apples.

\frac{apples}{bananas} = \frac{7}{3} = \frac{84}{x}

We just have to isolate x, this way and solve the problem:

\frac{7}{3} = \frac{84}{x}

becomes

x = \frac{84 * 3}{7} = \frac{252}{7} = 36

So, 36 students picked bananas as their favorite fruit.

Find the value of x, given that the two triangles are similar.​
8_murik_8 [283]

Answer:

10.5 is the correct answer.

Step-by-step explanation:

Due to the fact Triangle CAB has "6" as its length, and Triangle FDE has "2" as its length, you multiply 3.5 and 3.

3.5 x 3=10.5

2 x 3=6

3.5/2=10.5/6, so the answer is 10.5.

9) If m/1 = 45° and 21 and 22 are complementary angles. Find m22.​
Allisa [31]

❄ Hi there,

keeping in mind that the sum of complementary angles is 90°,

set up an equation, letting \angle2  be x  –

\triangleright \ \sf{\angle1+x=90}                 {and we know that \boxed{\angle1=45}}

\triangleright \ \sf{45+x=90}

\triangleright \ \sf{x=90-45}

\triangleright \ \sf{x=45}

\triangleright \ \sf{\angle2=45\textdegree}

      __________

Keeping in mind that a right angle is 90°,

set up an equation, letting \angle1 be x:

\triangleright \ \sf{x+\angle2=90}                       {and we know that \boxed{\angle2=63}}

\triangleright \ \sf{x+63=90}

\triangleright \ \sf{x=27}

\triangleright \ \sf{\angle1=47\textdegree}
