Hopefully this helps!
Step-by-step explanation:
Based on the given conditions,
Formulate:(100-80)÷80
Calculate the sum or difference:20/80
Cross out the common factor:1/4
Multiply a number to both the numerator and the denominator:1/4×25/25
Write as a single fraction :25/4×25
Calculate the product or quotient :25/100
Rewrite a fraction with denominator equals 100 to a percentage:25%
Answer : 25%
C. The square root of 144
Answer:8pennies,16dimes,13nickels,13quarters
Step-by-step explanation:
total number of coin=50
16% are pennies
16% of 50
16/100 x 50=(16x50)/100=800/100=8
Pennies=8
32% are dimes
32% of 50
32/100 x 50=(32x50)/100=1600/100=16
Dimes = 16
5 more nickels than pennies
Pennies=8
nickels=8+5=13
nickels=13
8+16+13=37
50-37=13
13 quarters
pennies=8,dimes=16,nickels=13,quarters=13
Answer:
y = -3x + 15
Step-by-step explanation:
The general structure for an equation is slope-intercept form is:
y = mx + b
In this form, "m" is the slope and "b" is the y-intercept.
The slope of a perpendicular line is the opposite signed, reciprocal of the original line's slope. So, if the slope in the original equation is (m = 1/3), the slope of the perpendicular line is (m = -3).
Now that we know the slope, we can use the "x" and "y" values from the given point to find the value of "b".
y = mx + b <----- Slope-intercept form
y = -3x + b <----- Plug -3 into m
-3 = -3(6) + b <----- Plug in "x" and "y" values from point (6,-3)
-3 = -18 + b <----- Multiply -3 and 6
15 = b <----- Add 18 to both sides
Since we identified that m = -3 and b = 15, you can substitute these values into the general equation to find the equation of the new line.
y = -3x + 15
