SpyIntel [72]

Answer: 167\dfrac15\text{ miles}.

Step-by-step explanation:

Since

64\dfrac45\text{miles}=\dfrac{64\times5+4}{5}\text{ miles}\\\\=\dfrac{324}{5}\text{ miles}

18\dfrac45\text{ miles}=\dfrac{18\times5+4}{5}\text{ miles}\\\\=\dfrac{94}{5}\text{ miles}

Total distance traveled during the trip = \dfrac{324}{5}+\dfrac{94}{5}+\dfrac{324}{5}+\dfrac{94}{5}

= \dfrac{836}{5}\\\\=167\dfrac15\text{ miles}

Hence, the distance traveled during their trip was 167\dfrac15\text{ miles}.

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or
belka [17]

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°.  So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).  

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

Pamela deposits $4,000 in an account that earns interest at 5% APR compounded weekly. What is her ending balance after 2 years?
Triss [41]
The answer is $4419.76

A = P (1 + r/n)^nt

Therefore,

A = 4000 (1 + 0.05/52)^52 x 2
A = 4000 (1.00096)^104
A = 4000 (1.1049)
A= 4419.76

Hope that helps!

Tatiana [17]
It would be A. 2x+15
Because you use the distributive property which equals 6x+15-4x
Then you add like terms so 6x-4x=2x soo 2x+15

Hope this helps
