Answer:
I think its c but im not sure
For this case, the first thing we must do is define variables.
We have then:
x = number of dimes
y = number of quarters
We write the system of equations:
0.10x + 0.25y = 4.55
x = y
Solving the system we have:
x = 13
y = 13
The value of the dimes is:
(0.10) * (13) = 1.3 $
Answer:
The value of only the dimes is:
1.3 $
Answer:
<h2>Yes</h2>
Step-by-step explanation:
The formula of a distance between two points:
ΔABC:
A(2, 5), B(5, 5), C(5, 9)
ΔDEF:
D(-7, 8), E(-4, 8), F(-4, 4)
AB ≅ DE
AC ≅ DF
BC ≅ EF
Therefore ΔABC ≅ ΔDEF
Okay.. So, when dividing a fraction you should multiply by the reciprocal (Just the fraction flipped around)
6/1 x 4/3
Originally you will get 24 over 3, but if you simplify that, you will get 8 over 1, or just 8. So, 8 would be your answer.

41) Circumference of a circle is 2*pi*radius, or pi*diameter.
Diameter given is 0.5cm, so circumference is 0.5pi, approximately 1.57cm.
It says scale is 1 cm to 2.5ft. Use dimensional analysis. You can multiply by 2.5ft / 1 cm because it equals 1, and multiplying by 1 doesn't change the value (just the units here).
1.57cm * 2.5ft
-------- = 3.925ft
1 cm
C) 4 feet
42) 6% of $900 is 0.06*$900, which is $54.
$900 is including tax, so subtract the tax ($54) to get the price before tax.
$900 - $54 = $846
A) $846
