Answer:

There are 4 boys and 17 girls in the class.

Step-by-step explanation:

Out of 21 students in Mrs. Clark's class, 5th of the students are boys and rest are girls.

out of 21 every 5th student is boy, so total boys are = \frac{21}{5}

                                                                                      = 4\frac{1}{5}

The whole number is 4, so the number of boys are 4.

The number of girls = 21 - 4 = 17 girls

There are 4 boys and 17 girls in the class.

alexdok [17]

Answer:

B:J:S

Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)

Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)

problem: report error when the measures of the angles of a triangle are placed in order, the difference between the middle angle
laiz [17]

The triangle's biggest angle's measurement in degrees is 97°.

What is a triangle?

  • A triangle is a polygon with three vertices and three sides. The angles of such a triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
  • All of the angles in an acute triangle are below 90 degrees.
  • Any angle in an obtuse triangle is larger than 90 degrees.
  • There is just one 90-degree angle in a right triangle.

Let a+b+c=180° with a < b < c

c-b=b-a\\c=2b-a | a=180-b-c\\c=2b-(180-b-c)\\c=2b-180+c+c | -c\\0=2b-180+b\\180=3b\\b=\frac{180}{3} \\b=60

Moving angle c of the triangle,

c=2b-a | a=23, b=60\\c=2(60)-23\\c=120-23\\c=97

The triangle's biggest angle's measurement in degrees is 97°.

:) y = (3 - x)(x + 2)​
valentina_108 [34]

Answer:

-x² + x + 6

Step-by-step explanation:

Hey there!

To solve this, you have to use foil...

( 3 - x ) ( x + 2 )

3 ( x + 2 ) = 3x + 6

-x ( x + 2 ) = -x² - 2x

3x + 6 - 2x - x²

-x² + x + 6

Hope this helps :)
