Answer:

40% of espresso was single-shot.

Step-by-step explanation:

To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.

Hope this helped, if your confused, just ask me :]

-Nific 0.9

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

 4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4

The formula relations given by Pythagorean theorem is used to

determine the lengths and area of the given squares and triangles.

Responses:

1. Area of a is H: 25

2. Length of b is I: 5

3. Length of C is A: 7.94

4. Area of d is B: 35.73

1. Given;

The area of the side squares are; 9 m² and 16 m²

According to Pythagorean theorem, we have;

Area of square a = 9 m² + 16 m² = 25 m²

2. b² = Area of side square a

Therefore;

b = √(25 m²) = 5 m

3. Given;

Area of the squares adjacent to the hypotenuse side and a leg are;

144 m² and 81 m² respectively

According to Pythagorean theorem, we have;

C² = 144 m² - 81 m² = 63 m²

C = √(63 m²) = √(9 × 7 m²) =  3·√7 m ≈ 7.94 m

4. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m

Answer:

24 years

Step-by-step explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

Step-by-step explanation:

Answer:

600

Step-by-step explanation:

We require to find the total number of words, that is 100%

Given 15% = 90 words

Divide 90 by 15 to find 1% and multiply by 100 for total , that is

number of words = [tex]\frac{90}{15}[/tex] × 100 = 6 × 100 = 600 ords

Answer:

the 13th one is 115

Step-by-step explanation:

11/60 will be the one - third the difference between 3/4 and 1/5.

When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one way for promoting consistency in job effort, cost, and duration. It removes diversity and variation that is harmful, meaningless, or superfluous.

Given, two fractions 3/4 and 1/5

Difference between these two fractions = 3/4 - 1/5

Difference between these two fractions = 15/20 - 4/20

Difference between these two fractions = 11/20

One-third of the difference = [tex]\frac{11}{20} * \frac{1}{3}[/tex] = 11*60

Therefore, The one-third difference between 3/4 and 1/5 will be 11/60.

Answer:

Hi, your answer will be 5/8 x 2/8.

Step-by-step explanation:

When multiplying fractions, you are to do both the numerators and denominators. So, if you do 5/8 x 2/8, that would result as 10/16. When you simplify, that would be 10/16 divided by 2, which is 5/8.

Answer:

45 degrees

Step-by-step explanation:

42 degrees is 42 “points” away from zero (picture a number line). -3 degrees is 3 points away from zero on the number line, but in the opposite direction. The two numbers are 45 “points” away from each other.

When they say find the difference, it’s a subtraction equation.

42 - (-3) = 42 + 3 = 45
