A large cheese pizza costs $7.50. Each additional topping for the pizza costs $1.35. If the total bill for the pizza Sally order

konstantin123 [22]

Answer: She ordered 4 toppings.

Step-by-step explanation:

Given: Total cost of pizza = $ 12.90

Cost of pizza =$7.50

Price per topping = $1.35

Let x = Number of toppings,

Total cost of pizza = (Cost of pizza) + (price per topping) × (Number of topping)

$12.90= 7.50+1.35x\\\\\Rightarrow\ 1.35x=12.90-7.50\\\\\Rightarrow\ 1.35x=5.4\\\\\Rightarrow\ x=\dfrac{5.4}{1.35}\\\\\Rightarrow\ x=\dfrac{540}{135}=4$

hence, she ordered 4 toppings.

What is the measure of angle c? (Brainliest and Bonus points for best answer)

k0ka [10]

Answer:

$\displaystyle 65°$

Step-by-step explanation:

Angle b and 135° form a linear pair, so when summing them up to 180°, you will have 45° left over:

$\displaystyle 180° = 135° + m∠b; 45° = m∠b$

Now, by the Vertical Angles Theorem, angle a and 70°, in this case, are to be in congruence with each other, so you have that.

Now you must find the the measure of angle c sinse you have already found the measure of two angles already:

$\displaystyle 180° = 45° + m∠c + 70° → 180° = 115° + m∠c; 65° = m∠c$

I am joyous to assist you at any time.

Harlamova29_29 [7]

If Vicki works 19 hours per week att $17.30 per hour, then her weekly savings is (17.30)(19) = $328.70 So, if she needs to save at least 4 000, then she it will take her (4000/328.70) which is approximately 12.17 weeks. That means she has to save for at least 13 weeks.
