∠DAB and ∠BAC (arc BC) are supplementary angles, angles which add up to 180°.

∠DAB + ∠BAC = 180°
26° + ∠BAC = 180°
∠BAC = 180° - 26°
∠BAC = 154°

The measure of ∠BAC (arc BC) is 154 degrees

Can y’all please answer this question

Answer:

The customer will pay $19

Option B is correct.

Step-by-step explanation:

Price of Ham per pound = $5.99

Price of Turkey per pound = $4.99

Price of Roast beef per pound = $6.99

Price of Salami per pound = $2.99

Price of Bologna per pound = $3.99

Customer purchased:

Ham = $\frac{1}{4}$ pound

Turkey = $1\frac{1}{2}=\frac{3}{2}$ pound

Roast beef = 1 pound

Bologna = $\frac{3}{4}$ pound

We will multiply the pound purchased with per pound price and add them to find the total cost.

The customer will pay :

$\frac{1}{4}\times5.99+\frac{3}{2} \times4.99+1\times6.99+\frac{3}{4}\times3.99$

$=1.4975+7.485+6.99+2.9925\\=18.965\\\approx19$

So, the customer will pay $19

Option B is correct.

Shinya went to the salon. The cost if her haircut was $16.00. He tipped the barber 15%. What was the total cost

Fantom [35]

Total cost=costofhaircut+tip
tip=costofhaircut times percent tip
percent tip=15%

percent means parts out of 100
15%=15/100=0.15

cost of haircut=16
tip=16 times 0.15=2.4

total cost=16+2.4=18.4

total cost=$18.40
