A triangular parking lot has two sides that are the same length and the third side is 5 m longer. If the perimeter is 71 m, find

Scilla [17]

Answer:

The equation can be expressed as;

x+y=71 where,

Lengths of two equal sides=x=22 m

Lengths of longer side=y=27 m

Step-by-step explanation:

The total perimeter can be expressed as;

Total perimeter=Total length of the equal sides+total length of the longer side

where;

Total perimeter=71 m

Total length of each of the equal sides=x m

Total length of longer side=y=(x+5) m

replacing;

x+y=71...equation 1

71=(2×x)+(x+5)

2 x+x=71-5

3 x=66

x=66/3

x=22 m

y=x+5=22+5=27 m

Lengths of two equal sides=22 m

Lengths of longer side=27 m

Equation;

x+y=71

Harry received a package for his birthday. The package weighed 350,000 centigrams. Select the conversions that are equivalent to

notsponge [240]

Given:

The package weighed 350,000 centigrams.

To find:

The conversions that are equivalent to 350,000 centigrams

Solution:

We know that,

1 centigrams (cg) = 0.000001 kilograms (kg)

1 cg = 0.1 decigrams (dg)

1 cg = 0.001 dekagrams (dag)

1 cg = 0.01 grams (g)

Using these conversions, we get

350,000 centigrams = 3.5 kilograms

350,000 centigrams = 35,000 decigrams

350,000 centigrams = 350 dekagrams

350,000 centigrams = 3,500 grams

Therefore the correct options are C and D.

Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder to the flour. Laura knows that 1 cup of

pickupchik [31]

The answer is She went over by one over six of a cup

1 cup of that particular chocolate powder has a mass of 128 grams: 1c = 128g

64 grams of chocolate powder is x cups.
1c = 128g
x = 64g

1c : 128 g = x : 64g
x = 1c : 128 g * 64 g
x = 0.5 c
64 grams of chocolate powder is 0.5 cups = 1/2 cups

She added two over three of a cup of chocolate powder: 2/3 cups

She need to add 1/2 cups: 1/2 = 3/6 cups
She added 2/3 cups: 2/3 = 4/6 cups

So she added 4/6 - 3/6 = 1/6 cups more.
