Answer the following.
nexus9112 [7]

Step-by-step explanation:

1075 students were asked how close they live to the college. The table shows the results below with some values missing. Enter the correct values in the boxes remembering to use the % symbol where necessary.

<u>20 to 25: </u>given 20%

20% of 1,075 = 215

<u>15 to 19: </u>given 12%

12% of 1,075 = 129

<u>10 to 14: </u>given 516 students

(516/1,075)*100 = 48%

<u>5 to 9: </u>given 162 students

(162/1,075)*100 = 15.07%

<u>< 5: </u>given 53 students

(53/1,075)*100 = 4.93%

Length of the base of the given triangle is (x+3) units and the perpendicular height is (x-1)units. If the area of the triangle
Lana71 [14]

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

so, in our case we know this is 10 :

(x+3)(x-1)/2 = 10

(x+3)(x-1) = 20

x² - x + 3x - 3 = 20

x² + 2x - 23 = 0

that is exactly the provided equation. so, yes, x satisfies it.

the general solution to a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 2

c = -23

x = (-2 ± sqrt(2² - 4×1×-23))/(2×1) =

= (-2 ± sqrt(4 + 92))/2 = (-2 ± sqrt(96))/2 =

= (-2 ± sqrt(16×6))/2 = (-2 ± 4×sqrt(6))/2 =

= -1 ± 2×sqrt(6)

x1 = -1 + 2×sqrt(6) = 3.898979486... ≈ 4

or using sqrt(6) ≈ 2.45

= -1 + 2×2.45 = -1 + 4.9 = 3.9 ≈ 4

x2 = -1 - 2×sqrt(6) = -5.898979486... ≈ -6

or using sqrt(6) ≈ 2.45

= -1 - 2×2.45 = -1 - 4.9 = -5.9 ≈ -6

x2 would give us negative lengths for the triangle, which does not make sense.

so, x = 4 is our solution.

and that makes the height x-1 = 4-1 = 3 units.

You are making a snack that includes 5/6 pound of almonds and 7/9 pound of cashews. Which is greater, the weigh of the almonds o
devlian [24]
To compare the answers, you need to have the same denominator. 

We know that, 18 is a common denominator between 6 and 9. 

(5/6)*3/3 => 15/18 (ALMONDS) 
(7/9)*2/2 => 14/18 (CASHEWS) 

As seen, the weight of almonds is 1/18 bigger than the cashews.

Hope I helped :)
