Answer:
David=$8.8
Jo=$13.2
Mary=$22
Step-by-step explanation:
2+3+5=10
44/10=4.4
David=4.4x2=$8.8
Jo=4.4x3=$13.2
Mary=4.4x5=$22
8.8+13.2+22=44
Answer:
120°.
Step-by-step explanation:
The sum of all interior angles in a polygon with
sides (
,
) is equal to
. (Credit: Mathsisfun.)
The polygon here has 6 sides.
. Its interior angles shall add up to
.
Consider the properties of a regular polygon. (Credit: Mathsisfun.)
- All sides in a regular polygon are equal in length.
- All angles in a regular polygon are also equal.
There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be
.
Answer:
20.25
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 135.
Step 2: We represent the unknown value with $x$
.
Step 3: From step 1 above,$135=100\%$
.
Step 4: Similarly, $x=15.\%$
.
Step 5: This results in a pair of simple equations:
$135=100\%(1)$.
$x=15.\%(2)$
.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{135}{x}=\frac{100\%}{15.\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{135}=\frac{15.}{100}$
$\Rightarrow x=20.25$Therefore, $15.\%$ of $135$ is
sorry if it took to long have a great day and brainliest is appreciated!!!!!
Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour
