A bag contains 55 coins of $1 and ¢50 denominations. Find the number of coins of each denomination, if the total amount in the bag is $40.
Answers
Answer:
Number of $1 coins are 25 and number of 50 cent coins are 30.
Step-by-step explanation:
Let's set up the equations.
Let there are x number of $1 coins
There are y number of 50 cent coins
So, x+y =55
1 x+0.50 y =40
Solve the equations for x and y.
Solve the first equation for y.
y=55-x
Substitute y as 55-x into the second equation.
1 x+0.50(55-x)=40
Solve the equation for 'x'.
Distribute the 0.50 to get rid the ( ).
1 x+27.5-0.50 x= 40
Combine like terms
0.50 x +27.5=40
Subtract both sides 27.5
0.50 x =12.5
Divide both sides by 0.50
x=25
Now, plug in x as 25
y=55-25
y=30
So, number of $1 coins are 25 and number of 50 cent coins are 30.
Which ordered pair makes both inequalities true?
y>-2x + 3

Given is rectangular prism, we need to find the volume of the same,
So, we know that the volume of a rectangular prism is the product of its dimensions.
V = length × width × height.
[tex]V = 16\frac{3}{4} \times 4\frac{2}{5} \times 3[/tex]
[tex]V = \frac{67}{4} \times \frac{22}{5} \times 3[/tex]

Find JK................
Answers
Answer:
24 unit
Step-by-step explanation:
From the question,
JK = 2×NK.................... Equation 1
Using pythagoras theorem,
a² = b²+ c²................. Equation 2
From the diagram,
a = 15 unit, b = 9 unit, and c = NK
Substitute these values into equation 2
15² = 9²+(NK)²
Solve for NK
225 = 81+(NK)²
(NK)² = 225-81
(NK)² = 144
NK = [tex]\sqrt{144}[/tex]
NK = 12 unit.
Substitute these value of NK into equation 1
JK = 2×12
JK = 24 Unit.

Ed solved a puzzle 3/4 faster than Brett. Brett solved the puzzle in 135 seconds. How long did it take Ed to solve the puzzle.
Answers
Answer:
101.25 seconds.
Step-by-step explanation:
We know that Ed solved the puzzle 3/4 faster than Brett.
Then if Brett solved the puzzle in a time T, Ed solved the puzzle in a time (3/4)*T.
We know that Brett solved the puzzle in 135 seconds, then:
T = 135s
This means that Ed solved the puzzle in:
time = (3/4)*T = (3/4)*135s = 101.25 seconds.
what is the value of x? 26 degrees tangent lines
Answers
Answer:
154°Step-by-step explanation:
The central angle and the angle between the tangents are supplementary, so
x + 26° = 180° ( subtract 26° from both sides )
26 - 26 = 0
180 - 26 = 154
x = 154°
The value of the x will be 154°.
How to find the interior central angle?The central angle and the angle between the tangents are supplementary.
If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to line L.
So,
x + 26° = 180°
Subtract 26° from both sides;
x + 26 - 26 = 180 - 26
x = 154°
Hence, the value of the x will be 154°.
