Answer

x times y = xy

x + y times a + b = (x + y)(a + b)

For that you can use the FOIL method which is First, Outside, Inside, Last.

First: x times a = ax

Outside: x times b = bx

Inside: y times a = ay

Last: y times b = by

So you have ax + bx + ay +by.

If you end up using numbers, then you can simplify.

Ask your teacher or parents. It's easier to explain in person.

5 2/5 as a mixed number

valentina_108 [34]

Answer:

Mixed numbers have a whole number followed by the fraction (2 1/2). You would say "two and one half." The other format is an improper fraction where the numerator is greater than the denominator (5/2). Mathematicians would say that is five halves.

g A 5 foot tall man walks at 10 ft/s toward a street light that is 20 ft above the ground. What is the rate of change of the len

vredina [299]

Answer:

$-\frac{10}{3}ft/s$

Step-by-step explanation:

We are given that

Height of man=5 foot

$\frac{dy}{dt}=-10ft/s$

Height of street light=20ft

We have to find the rate of change of the length of his shadow when he is 25 ft form the street light.

ABE and CDE are similar triangle because all right triangles are similar.

$\frac{20}{5}=\frac{x+y}{x}$

$4=\frac{x+y}{x}$

$4x=x+y$

$4x-x=y$

$3x=y$

$3\frac{dx}{dt}=\frac{dy}{dt}$

$\frac{dx}{dt}=\frac{1}{3}(-10)=-\frac{10}{3}ft/s=-\frac{10}{3}ft/s$

Hence, the rate of change of the length of his shadow when he is 25 ft from the street light= $-\frac{10}{3}ft/s$

child admission is $5.90 and adult admission is $9.10 . 175 tickets were sold for a total sales of $1282.10 . How many child tic

GenaCL600 [577]

Answer:

Child tickets are 97

Step-by-step explanation:

x + y = 175 ...............(1)

x = 175 - y

5.90x + 9.10y = 1282.10. .........(2)

5.90 (175 - y) + 9.10y = 1282.10

1032.50 - 5.9y + 9.10y = 1282.10

3.2y = 249.60

y = 249.6. / 3.2

y = 78

From equation 1

x + y = 175

x + 78 = 175

x = 175 - 78

x = 97

Which equation is equivalent to log^x36=2?

Dennis_Churaev [7]

The equation which is equivalent to $\log _{x} 36=2$ is $x^{2}=36$ or x = 6 ( $\log _{6} 36=2$ ).

<u>Step-by-step explanation:</u>

Given Equation:

$\log _{x} 36=2$

As we know, in terms of logarithmic rules, when b is raised to the power of y is equal x:

$b^{y}=a$

Then, the base b logarithm of x is equal to y

$\log _{b}(x)=y$

Now, use the logarithmic rule for the given equation by comparing with above equation. We get b = x, y = 2, and x = 36. Apply this in equation,

$b^{y}=a$

$x^{2}=36$

When taking out the squares on both sides, we get x = 6. Hence, the given equation can be written as $\log _{6} 36=2$
