Step-by-step explanation:
Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4
Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4
Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8
Quotient: 6*10^-4/1.5 * 10^-4 = 4
Notice the answers, because they give you the rules.
When adding exponents and rationales, if the powers are the same then the rationales merely add.
Same rule applies to subtraction. Retain the powers and subtract the rationales.
When multiplying the rationales multiply, but the rationales add. they don't stay the same.
When dividing, the rationales divide and the powers subtract -- numerator minus denominator

c is correct. To verify this, look at the point (4, 4) on the black graph. For the same x value (4), we have on the red graph the point (4, 2). If we now look at this point (4, 2) on the red graph we see that the y-value (2) is half that of the point (4, -4) on the black graph: f(x) = (1/2)y

Rectangle has side 5 cm so one side of triangle will be 5cm
area of triangle is = 1/2lb
= 1/2 5*4
=10 cm^2
area of rectangle is l*b = 5*3= 15 cm^2
are of the shape is 10+ 15= 25 cm^2
Area of rectangle is 6*8 = 48 m^2
Area of triangle is = 1/2 *8*2= 8 m^2
area of the shape is 48+8= 56m^2

Answer:
m ∠ 2 = 19 * 3 = 57°
Step-by-step explanation:
m ∠ 1 = x
m ∠ 2 = 3x
m ∠ 1 + m ∠ 2 = 76°
3x + x = 76°
4x = 76°
Divide both sides by 4;
x = 19°
m ∠ 1 = 19°
m ∠ 2 = 19 * 3 = 57°

Find the value of x and then find EF if E is the midpoint of line segment DF.
DE = 15 - 3x
EF = x + 3
Answers
Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the amount of money, M, he has after he has done laundry “x” times?
A) M= 7.50x - 240
B) M= 240 - 7.50x
C) M= 7.50 - 240x
D) M= 240x - 7.50
Answers
Answer:
B
Step-by-step explanation:
x = the number of times he does laundry.
Let's say he does the laundry 5 times then x = 5.
Each time costs $7,50.
If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.
M stands for how much money he still has left from the 240 dollars.
If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'
Therefore, the correct answer is B (M = 240 - 7.50x).
