A recipe calls for 112 cups of mayonnaise and 38 cups of pecans. How much mayonnaise should be used if 1 cup of pecans is used?
Sauron [17]

Answer:

3 cups of mayonnaise will be required for 1 cup of pecan.

Step-by-step explanation:

A recipe calls for 112 cups of mayonnaise and 38 cups of pecans.

By using unitary method,

∵ 38 cups of pecans require mayonnaise = 112 cups

∴ 1 cup pecans requires mayonnaise = \frac{112}{38} cups

                                                             = 2.95 cups

                                                             ≈ 3 cups

Therefore, 3 cups of mayonnaise will be required for 1 cup of pecan.

A ladder 6.5 m long rests against a vertical wall. If the foot of the ladder is 2.5m from the foot of the wall find upto how muc
Burka [1]

Answer:

The ladder reaches a height of 6 m.

Step-by-step explanation:

Given that,

Height of the ladder, H = 6.5 m

The foot of the ladder is 2.5 m from the foot of the wall.

We need to find the height does the ladder reach. If we consider a triangle in which hypotenuse is 6.5 m, foot of the ladder is 2.5 m then we need to find the height of the ladder i.e.

H^2=b^2+h^2\\\\h^2=H^2-b^2\\\\h^2=(6.5)^2-(2.5)^2\\\\h=6\ m

The ladder reaches a height of 6 m.

Help!!!
Mrrafil [7]

Answer:

∠ ADC = 53°

Step-by-step explanation:

Note the angle between the radius and the tangent is 90°

The sum of the angles in quadrilateral AOCB = 360°, thus

∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°

∠ AOC is twice the angle on the circumference ∠ ADC, thus

∠ ADC = 106° ÷ 2 = 53°
