Find out how many children there are first. Come on, this is simple fractions/percents/decimals/ratios.

The ratio of adults being 5:3 means that you should first divide the audience into 8 sections. You get 18. Now, you can multiply 18 by 5 to find out how many adults there are, since 5 means quantity of adults.

There are 90 adults

Given the statement, LEI=BNZ and the diagrams shown, determine the value of x.

WARRIOR [948]

Answer:

x = 20

Step-by-step explanation:

Given the triangles are congruent then corresponding angles are congruent, so

∠ N = ∠ E

To calculate ∠ E subtract the sum of the 2 given angles from 180

∠ E = 180 - (x - 5 + 4x - 10)

= 180 - (5x - 15)

Equate ∠ N and ∠ E

5x - 5 = 180 - 5x + 15 ( add 5x to both sides )

10x - 5 = 195 ( add 5 to both sides )

10x = 200 ( divide both sides by 10 )

x = 20

Solve x2 + 8x − 3 = 0 using the completing-the-square method

nikklg [1K]

Hello :
x²+8x-3=0
(x² +2(4)x +4²) -4² -3 = 0
(x+4)²-19 = 0
(x+4)² = 19
x+4 = √19 or x+4 = - √19
x = √19 - 4 or x = -√19 - 4

P and W are twice-differentiable functions with P(7)=2(W(7)). The line y=9+2.5(x-7) is tangent to the graph of P at x=7. The lin

fiasKO [112]

Using the product rule, we have

$m(x) = x W(x) \implies m'(x) = xW'(x) + W(x)$

so that

$m'(7) = 7W'(7) + W(7)$

The equation of the tangent line to W(x) at x = 7 has all the information we need to determine m' (7).

When x = 7, the tangent line intersects with the graph of W(x), and

y = 4.5 + 2 (7 - 7) ==> y = 4.5

means that this intersection occurs at the point (7, 4.5), and this in turn means W (7) = 4.5.

The slope of this tangent line is 2, so W' (7) = 2.

Then

$m'(7) = 7\cdot2 + 4.5 = \boxed{18.5}$
