In the given question Laura has $30 to spend on food for the week.

According to the question we have to set the inequality between total amount and amount spent on food.

Amount spend by Laura on food for the week = $30

Let the amount spent by Laura on food be x

So she has to spend up to $30

So inequality will be x\leqslant 30

So option b is the answer

Answer:

2) m∠CBD = 25°

   The measure of arc CDB = 230°

4) m arc XY = 10°

   The measure of arc WZX = 330°

6) The answer is (c) ⇒ 10 millimeters

Step-by-step explanation:

2) ∵ the measure of arc BC = 130°

∵ Arc BCD is the semi-circle its measure 180°

∴ The measure of arc cd = 180 - 130 = 50°

∵ ∠CBD is inscribed angle subtended by arc CD

∴ m∠CBD = 1/2 measure arc CD

∴ m∠CBD = 50 ÷ 2 = 25°

∵ The measure of the circle is 360°

∵ The measure of arc BC = 130°

∴ The measure of arc CDB = 360 - 130 = 230°

4) ∵ The measure of arc WY = 40°  

   ∵ The measure of arc XZ = 30°

   ∵ The measure of arc WZ = 60°

∵ m arc WY + m arc XZ - m arc XY = m arc WZ

∴ m arc XY = 40 + 30 - 60

∴ m arc XY = 10°

∵ The measure of the circle is 360°

∴ The measure of arc WZX = 360 - m arc WX

∵ The measure of arc WX = WY - XY = 40 - 10 = 30°

∴ The measure of arc WZX = 360 - 30 = 330°

6) In the circle O

∵ OC ⊥ AB and OX ⊥ ZY

∵ OC = OX

∴ AB = ZY ⇒ Theorem

∵ AB = 10 millimeters

∴ ZY = 10 millimeters ⇒ answer (C)
