Answer:
Slope is 40
Full equation: y=40x-586
Step-by-step explanation:
Slope is y2-y1/x2-x1
14 is x1
-26 is y1
15 is x2
14 is y2
14-(-26)/15-14
40
So the slope is 40
To find the equation
y=40x+b
14=15(40)+b
14=600+b
b=-586
Equation:
y=40x-586
The chance is 50% because if there are 2 children the probability would be 1/2 or 50%.
<u>He paid $ 32.10
</u>
because
07 * 30 = <u>2.10
</u>
2.10 + 30 = <u>$ 32.10</u>
Answer:
<h2><em>
38°, 66° and 76°</em></h2>
Step-by-step explanation:
A triangle consists of 3 angles and sides. The sum of the angles in a triangle is 180°. Let the angle be <A, <B and <C.
<A + <B + <C = 180° ...... 1
If the measure of one angle is twice the measure of a second angle then
<A = 2<B ...... 2
Also if the third angle measures 3 times the second angle decreased by 48, this is expressed as <C = 3<B-48............ 3
Substituting equations 2 and 3 into 1 will give;
(2<B) + <B + (3<B-48) = 180°
6<B- 48 = 180°
add 48 to both sides
6<B-48+48 = 180+48
6<B = 228
<B = 228/6
<B =38°
To get the other angles of the triangle;
Since <A = 2<B from equation 2;
<A = 2(38)
<A = 76°
Also <C = 3<B-48 from equation 3;
<C = 3(38)-48
<C = 114-48
<C = 66°
<em>Hence the measures of the angles of the triangle are 38°, 66° and 76°</em>
