Malik buys and sells car parts. He bought 2 tires for $45.00 each and later sold them for $65.00 each. He bought 3 rims for $85.
scZoUnD [109]

Answer: Malik's total profit is $213

Step-by-step explanation:

2 * 45 = 90

2 * 65 = 130

130 - 90 = 40

3 * 85 = 255

3 * 126 = 378

378 - 255 = 123

5 * 5 = 25

5 * 15 = 75

75 - 15 = 50

50 + 40 + 123 = 213

If it takes Ohenhen 10km to pass to Emma and it takes Emma 8km to pass to Omusi and considering Ohenhen &amp; Omusi are at perpe
mash [69]

Answer:

12.81 km

Step-by-step explanation:

Pythagoras formula for right-angled triangles.

this scenario just says that Emma is the corner point of that triangle with an angle of 90 degrees.

the distance between Ohenhen and Omusi is the baseline (Hypotenuse c) of that triangle. and the distances to Emma are the sides a and b.

so the formula is

c² = a² + b² = 10² + 8² = 100 + 64 = 164

c =  \sqrt{164}

c ≈ 12.81 km (rounded to the nearest hundredth).

Mekhanik [1.2K]

Answer: Yes, it will be enough.

Step-by-step explanation:

I will answer this in English:

We have 27 students and 81 units, we want to give 3 units to each student.

This is only possible if the quotient betwen 81 and 3 must be bigger than 27.

Lets do it:

81/3 = 27

So we have exactly enough for the 27 students.
