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

Answer: 72 degree

Step-by-step explanation:

By Angle Sum Property,

53 + 100 + angle C = 180

153 + angle C = 180

angle C = 180 - 153

       =    72 degree

Answer: 27

Step-by-step explanation:

The full triangle has to equal 180

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:

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:

7/256

Step-by-step explanation:

an = a1 * (1/2)^n-1

a9 = 7(1/2)^8

a9 = 7/256

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.

Answer:

figuring it out now

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.

see below <3 i hope this helps!

Step-by-step explanation:

What is the theoretical probability that the family has two dogs or two cats? (1/2)

The choices are dd, dc, cd, cc

There are 4 choices = dd or cc/ total = 2/4 = 1/2

Let the heads of the coin be dogs and the tails of a coin be cats

Flip two coins and coin A is the first pet and coin B is the second pet

heads , heads = 10

heads, tails  14

tails heads  =13

tails tails =  13

         total 50

Experimental probability  2 dogs or 2 cats = ( hh, tt) /total = ( 10+13) /50 =                    23/50

If we had 3 pets  

what is the theoretical probability that they have three dogs or three cats?

ddd, ddc, dcd, dcc, ccc, ccd ,cdc, cdd

There are 8 options

ddd or ccc/ total = 2/8 = 1/4

Let the heads of the coin be dogs and the tails of a coin be cats

Flip three coins and coin A is the first pet and coin B is the second pet Coin C be the third pet. ///////////// Did this help? :3 If so please give brainliest bc this took a while to type

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

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.

y = 3/2x is the answer for this problem.
