You spend 90 minutes practicing flip tricks and slides on your skate board the ratio of time spent on flip tricks to time spent

marshall27 [118]

42 minutes are spent on practicing flip tricks and 48 minutes are spent on practicing slides.

Step-by-step explanation:

Total practicing time = 90 minutes

Ratio of time spent on flip tricks to slides = 7:8

Let,

x be the total time spent on flip tricks and slides, therefore,

Time spent of flip tricks and slides = 7x+8x = 15x

Total time spent practicing = 15x

$15x=90$

Dividing both sides by 15

$\frac{15x}{15}=\frac{90}{15}\\x=6$

Time spent of flip tricks = 7x = 7*6 = 42 minutes

Time spent on slides = 8x = 8*6 = 48 minutes

42 minutes are spent on practicing flip tricks and 48 minutes are spent on practicing slides.

『Fast Please！』

Examples - Measurements in cooking; Metric measurements (7 1/4”); Distance (9 1/2 miles)

Real-World Problem - You’re baking and need to triple a recipe. The recipe calls for 3 3/4 cups flour (per recipe). You’d need to triple that amount to make how much you’re looking to make. (3 x 3 3/4 = 11 1/4 cups flour)

A civil engineer is drawing a plan for the location and length of a new underground sewer pipe on a coordinate grid. The pipe on

dimaraw [331]

Answer:

Step-by-step explanation:

If the pipe on the plan runs from point N(a, -2) to point P(1, b), the expression that represents the shortest distance between N and P in units, is expressed using the formula;

D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates N(a, -2) and P(1, b);

x₁ = a, y₁ = -2, x₂ = 1 and y₂ = b

NP = √(1-a)²+(b+2)²

<em>Hence the expression that represents the shortest distance between N and P in units is √(1-a)²+(b+2)² units</em>
