What number is 35% of 22?

1 answer:

<span>The answer is 7.7. Let x be the number we are looking for. So x is 35% and we know that 22 is 100%. Make a proportion: x : 35% = 22 : 100%. Cross the products: x * 100% = 22 * 35%. x * 100% = 770%. x = 770% : 100%. x = 7.7. Thus, 7.7 is 35% of 22. </span>

victus00 [196]

Answer:

No

Step-by-step explanation:

x = -2 represents a vertical line that intersects the x axis at the point (-2, 0). Since the line is vertical, the slope is undefined making it not have a positive slope.

Vectors a = (2, 4) , b = (−1, 2), and c = (c1, c2) all have the initial point at the origin, what are the coordinates of their t

Ket [755]

Answer:

A(2,4), B(-1,2). and C $(c_1,c_2)$

Step-by-step explanation:

If a vector has terminal point with coordinates P(x,y) and an initial point at the origin (0,0), then

$\vec{p}=\binom{x}{y}-\binom{0}{0}\\\implies \vec{p}=\binom{x}{y}$

Therefore if

$\vec{a}=\binom{2}{4}\\ \vec{b}=\binom{-1}{2}\\\vec{c}=\binom{c_1}{c_2}$

Then the coordinates of their terminal points are A(2,4), B(-1,2). and C $(c_1,c_2)$

On aunt may's barn there are 40 animals running around. Her niece counts 80 eyes, but counts 110 legs! the animals that are runn

mylen [45]

Her niece sees 15 goats.

Step-by-step explanation:

Given,

Total animals on barn = 40

Total legs counted by May's niece = 110

A goat has 4 legs and chicken has 2 legs.

Let,

x represent the number of goats

y represent the number of chicken

x+y=40 Eqn 1

4x+2y=110 Eqn 2

Multiplying Eqn 1 by 4

$4(x+y=40)\\4x+4y=160\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(4x+4y)-(4x+2y)=160-110\\4x+4y-4x-2y=50\\2y=50$

Dividing both sides by 2

$\frac{2y}{2}=\frac{50}{2}\\y=25$

Putting y = 25 in Eqn 1

$x+25=40\\x=40-25\\x=15$

Her niece sees 15 goats.
