Can any one me plzzz. i really need a now

Hi !

Total soup : 6.5L = 6 500 mL

Portions of 280 mL : 6 500 ÷ 280 ≈ 23,21 ≈ 23 portions

23 > 22

Joy definitely does have enough soup

6.5 liters of soup, correct to nearest 0.5 liters.
⇒ Lower bound = 6.450 liters = 6450 ml
⇒higher bound = 6.549 liters = 6549 ml

She served soup in 280 ml, correct to nearest 10ml
⇒ Lower bound = 275 ml
⇒higher bound = 284 ml

To ensure that we definitely have enough, we take the lower bound of the soup divided by the higher bound of each serving:

6450 ÷ 284 = 22.7 servings.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
