Answer:

0.4

Step-by-step explanation:

You need to divide the 6 by 15 in order to get 0.4.

Ratios, fractions, decimals, and percentages are all pretty much each other, as ratios are just fractions but sideways with the colon in between the numbers. Ratios are to show a relationship, as well as the others. Fractions and ratios are decimals, as you can just simplify them into decimals. Percentages are just decimals but with the decimal moved over to the left twice. So 0.43 becomes 43%.

1.49 becomes 149%

0.00432 becomes 0.432%

Answer: B. 30

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

When given a secant and a tangent, the formula is:

exterior of secant × secant = tangent²

KM × JK = LK²

10 × (JM + 10) = 20²

10JM + 100 = 400

10JM = 300

JM = 30

At the city museum, child admission is $5.20 and adult admission is $9.50. On Friday,133 tickets were sold for a total sales of

fredd [130]

Answer:

55 adult tickets were sold on Friday.

Step-by-step explanation:

A linear system will be used to model the system.

Let c be the number of child tickets and a be the number of adult tickets

Then according to given statements

$a+c = 133\ \ \ \ Eqn\ 1\\9.50a+5.20c = 928.10\ \ \ Eqn\ 2$

From equation 1

$a = 133-c$

Putting this in equation 2

$9.50(133-c)+5.20c = 928.10\\1263.5-9.50c+5.20c=928.10\\1263.5-4.3c = 928.10\\-4.3c = 928.10-1263.5\\-4.3c=-335.4\\\frac{-4.3c}{-4.3} = \frac{-335.4}{-4.3}\\c = 78$

Putting c = 78 in equation 1

$a+78 = 133\\a = 133-78\\a = 55$

Hence,

55 adult tickets were sold on Friday.

Answer:

<h2>∠Q corresponds with ∠Z</h2>

Step-by-step explanation:

form a graph
draw Δ ZNM and ΔPQR on either side of the y- axis
You reflect ΔZMN across the y- axis
Then you translate said triangle up the graph
The corresponding ∠'s will match and overlap.
m∠Q ≅ m∠Z as well as being a corresponding triangle

Suppose you walk 2 miles in 35 minutes. 4. write a proportion to find how far you would walk in an hour if you were to continue

Mrac [35]

Distance traveled in 35 minute = 2 miles.

So distance traveled in one minute = 2/35 (miles/minute)
= 0.0572 miles / minute.

So distance traveled in one hour , we can find by multiplying it from 60.Because in one hour there is 60 minute.

SO distance traveled in one hour = 0.0572 * 60
= 3.432 miles / hour.
