The ratio of boys to girls in a class is 5:3. There are 32 students in the class. How many students are boys?

alina1380 [7]

Class ratio of girls to boys is 3:5
So there are 3 girls and 5 boys in 8 students
If there are 32 students, then 3/(3+5) * 32 = 12 girls, and 5/(3+5) * 32 = 20 boys

Hope it helps you?

If 2:7 is expressed in the form for 4. Find the value of x.

Lelechka [254]

Answer:

x = 14

Step-by-step explanation:

Given that,

2:7 is expressed in the form for 4:x.

We need to find the value of x.

2:7 must be equated to 4:x.

So,

$2:7=4:x\\\\or\\\\\dfrac{2}{7}=\dfrac{4}{x}\\\\x=\dfrac{7\times 4}{2}\\\\x=14$

So, the value of x is equal to 14.

The width of a rectangle field is 3h yards and its length is 3 yards longer than the width. The field has a fence around its per

d1i1m1o1n [39]

Answer:

Part a) $P=(12h+2)\ yd$

Part b) The expression that represent the cost of fencing the field is $(336h+56)$

Part c) $\$1,736$

Step-by-step explanation:

The complete question in the attached figure

Part a) we know that

The perimeter of the rectangular field (excluding the width of the gate) is equal to

$P=2(L+W)-4$

we have

$L=(3h+3)\ yd\\W=3h\ yd$

substitute the given values

$P=2(3h+3+3h)-4$

$P=2(6h+3)-4\\P=12h+6-4\\P=(12h+2)\ yd$

Part b) we know that

To find out the cost of fencing the field (excluding the gate) , multiply the perimeter by the cost of $28 per yard

$28(12h+2)=336h+56$

Part c) we have

h=5

substitute the value of h in the expression of the cost

$336(5)+56=\$1,736$

AA, SAS, SSS or not similar ?

Mariana [72]

Answer:

SSS

Step-by-step explanation:

KN / PD = 54/24 = 2.25

KB / PF = 49.5/22 = 2.25

BN / DF = 40.5/18 = 2.25

ΔKBN ~ PDF (SSS) : two triangles are similar, their corresponding sides are in equal proportion.
