A man works five consecutive and makes $15.50 per hour.
Answer:
0
Step-by-step explanation:
8x + 4 = 3x - 3 +7
u first expand the bracket as I have done above
then u evaluate those who have like terms close like -3 + 7
8x + 4 = 3x + 4
then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation
8x - 3x = 4 - 4
8x - 3x = 0
5x = 0
then u divide both side by the coefficient of x
0/5 but any number divided by 0 is 0, so x = 0
Answer: b
7(b-1)/b less than or equal to 0
Step-by-step explanation:
Up to the left and then up to the right
A) Find KM∠KEM is a right angle hence ΔKEM is a right angled triangle Using Pythogoras' theorem where the square of hypotenuse is equal to the sum of the squares of the adjacent sides we can answer the
KM² = KE² + ME²KM² = 8² + (3√5)² = 64 + 9x5KM = √109KM = 10.44
b)Find LMThe ratio of LM:KN is 3:5 hence if we take the length of one unit as xlength of LM is 3xand the length of KN is 5x ∠K and ∠N are equal making it a isosceles trapezoid. A line from L that cuts KN perpendicularly at D makes KE = DN
KN = LM + 2x 2x = KE + DN2x = 8+8x = 8LM = 3x = 3*8 = 24
c)Find KN Since ∠K and ∠N are equal, when we take the 2 triangles KEM and LDN, they both have the same height ME = LD.
∠K = ∠N Hence KE = DN the distance ED = LMhence KN = KE + ED + DN since ED = LM = 24and KE + DN = 16KN = 16 + 24 = 40
d)Find area KLMNArea of trapezium can be calculated using the formula below Area = 1/2 x perpendicular height between parallel lines x (sum of the parallel sides)substituting values into the general equationArea = 1/2 * ME * (KN+ LM) = 1/2 * 3√5 * (40 + 24) = 1/2 * 3√5 * 64 = 3 x 2.23 * 32 = 214.66 units²
