if the ratio of type O to non-type O donors at a blood drive was 37:43. how many would be type O out of 300 donors? will try and mark brainliest . please show the work as well

Answers

Answer:

Step-by-step explanation:

Proportion of type O donors = 37/(37+43) = 37/80

300 × 37/80 = 138.75

139 donors out of 300 are type O.

A ratio shows us the number of times a number contains another number. The number of type O donors out of 300 is 139.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that the ratio of type O to non-type O donors at a blood drive was 37:43. Therefore, the number of type O blood donors be represented by 37x and the number of non-type O blood donors be represented by 43x.

Now, the sum of type and non-type O donor is 300. Therefore, we can write,

37x + 43x = 300

80x = 300

x = 3.75

Further, the Number of type O donors out of 300 can be written as,

Number of type O donors out of 300 = 37x = 37(3.75) = 138.75 ≈ 139

Hence, the number of type O donors out of 300 is 139.

Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0

Answers

Answer:

y = -x² + 4x

Step-by-step explanation:

The standard form:

y = ax² + bx + c

Pairs given:

(0, 0), (2, 4), (4, 0)

Substitute values of x and y and work out the values of a, b and c.

1. Point (0, 0)

0 = a(0)² + b(0) + c  ⇒ c = 0

2. Point (2, 4)

4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a

3. Point (4, 0)

0 = a(4)² + b(4) ⇒ 16a + 4b = 0

Substitute b and solve for a:

16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1

Find b:

b = 2 - 2(-1) = 2 + 2 = 4

The function is:

Angel está adaptando un espacio para hacer actividades recreativas en casa y quiere rodear el borde con plantas, cuántos metros mide el borde si la ecuacion para calcularlo es 2a+2b, donde a representa el ancho y b el largo del espacio, a=1 metro y b=2 metros

Answers

Answer:

El borde mide 6 metros.

Step-by-step explanation:

Sabemos que la ecuación para el borde está dada por:

borde = 2*a + 2*b

Si sabemos que:

a = 1 metro

y  

b = 2 metros

podemos simplemente remplazar esos valores en la ecuación para el borde, asi obtendremos:

(es decir, donde hay una "a" en la ecuación, escribimos "1 metro", y end donde hay una "b" en la ecuación, escribimos "2 metros", luego resolvemos)

borde = 2*(1 metro) + 2*(2 metros) = 2 metros + 4 metros =  6 metros.

Podemos concluir que el borde mide 6 metros.
