dallas got a raise.His hourly wage was increased form $9 to $10.25? What was the percent increase in Dallas's wage to the neares

steposvetlana [31]

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Increase = $10.25 - $9
% increase= $1.25/$9 x 100

% increase=13.888888889
% increase= 14%

The slope of a line is the ratio of the change of y to the change of X. Name the trigonometric ratio of theta that equals the sl

Elanso [62]

Answer:

The trigonometric ratio of theta is tangent ⇒ answer (c)

Step-by-step explanation:

* Lets revise the trigonometry functions

- sinФ = the side opposite to angle Ф ÷ the hypotenuse

- cosФ = the side adjacent to angle Ф ÷ the hypotenuse

- tanФ = the side opposite to angle Ф ÷ the side adjacent to angle Ф

* Now read the definition of the slope and look to the figure

- The slope of a line is the ratio of the change of y to the change of x

∵ The change of y is opposite to angle Ф

∵ The change of x is adjacent to angle Ф

∴ The slope = the side opposite to Ф ÷ the side adjacent to Ф

* The slope of the line = tanФ

∴ The trigonometric ratio of theta is tangent

M is directly proportional to r squared

Nesterboy [21]

Answer:

m=84

r:m = 1:7

therefore when r= 1 then M=14

$r = 12 \\ m = 7 \times 12 \\ m = 84$

I think that's how you do it

Write these numbers in order of size,

Katyanochek1 [597]

Answer:8.8 km, 8810 m, 8812 m, 8.821 km, 8.9 km, 8901 m

Step-by-step explanation:

8810 m, 8.9 km, 8901 m, 8.821 km, 8812 m, 8.8 km

which mean

8810 m, 8900 m, 8901 m, 8821 m, 8812 m, 8800 m

arrange accordingly

8800 km, 8810 m, 8812 m, 8821 m, 8900 m, 8901 m

convert back

8.8 km, 8810 m, 8812 m, 8.821 km, 8.9 km, 8901 m

From the information given, determine which triangles, if any, are congruent and state by which rule. If the triangles cannot be

cluponka [151]

<h2>Answer:</h2>

Triangles ΔADM and ΔUTM are congruent by SAS postulate.

<h2>Step-by-step explanation:</h2>

We say that two triangles are congruent<em> </em> <em>if and only if </em> they have exactly the same three sides and exactly the same three angles. So if you can turn one triangle into the other by moving, rotating or flipping, then they are definitively congruent. The symbol we use for expressing congruency is ≅. Since triangles ΔADM and ΔUTM have two matching sides and a matching angle between them, then they are congruent by SAS Postulate (Side Angle Side). Then:

ΔADM ≅ ΔUTM
