Given ZW=20. Answer the questions please. ​
djyliett [7]

a) Corresponding angles of similar figures are congruent, so \angle B \cong \boxed{\angle Z}

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is \frac{25}{10}=\boxed{5/2}

c) Since the scale factor is 5/2,

\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}

Jaleesa bought 2 notebooks for $8. 75 each and 1 textbook for $74. 95. If the sales tax was 7%,
weeeeeb [17]

Answer:

Step-by-step explanation:

First calculate the amount of notebooks and textbook

Cost of 2 notebooks = 2 *8.75

                                  = $ 17.5

Cost of 1 textbook = $ 74.95

Total cost = 17.5 + 74.95

                 = $ 92.45

Tax = 7% of total cost

      = 0.07 * 92.45

      = $ 6.47

Total cost = 92.45 +6.47

                 = $ 98.92
