Answer:

Step-by-step explanation:

Two angles that are directly across from each other when two lines intersect are called vertical angles.  Vertical angles are ALWAYS congruent to each other. Very good thing to know when it comes to proving triangle congruency.

Answer:

If two lines intersect each other, then the vertically opposite angles are equal. Theorem 6.1 : If two lines intersect each other, then the vertically opposite angles are equal. In the statement above, it is given that 'two lines intersect each other'. So, let AB and CD be two lines intersecting at O

In a package of 40 skittles, 35% were red. How many were not red?
wel
Answer:

40 skittles times the percent of red

40 * 0.35 = 14

We then take that then subtract that from the total.

40 - 14 = 26

26 skittles were red.

0.35 is equivalent to 35%

Help meeeeeeeeeeee:(
Vaselesa [24]

Answer:

1/3

Step-by-step explanation:

(1/3)^2x(1/3)^-1

so, we can write this as:

1/3 x 1/3 x 3/1

if calculated by cutting, the answer is 1/3

There is also an easier way to do this,

(1/3)^2 x (1/3)^-1

as the bases are same, the powers will be added.

2+(-1)

2-1

=1

so,

(1/3)^1 or 1/3

Nina [5.8K]

Answer:

(a) y=8x+5

(b) 7 hours.

Step-by-step explanation:

(a) Let x be the number of hours and y is the total cost.

We have been given that Beatrice and her friends charge $8 per hour of babysitting, so the charges for x hours of babysitting will be 8x.

As they also charge a mandatory $5 per day fee for each child for snacks, so the total charges for babysit each day will be charges for x hours of babysitting plus mandatory charge.

We can represent this information in an equation as:

y=8x+5

Therefore, the equation y=8x+5 represents the total cost of using Beatrice’s babysitting service each day.

(b) To find the number of hours Beatrice babysit the daughter, we will substitute y = 61 in our equation and solve for x.

61=8x+5

Let us subtract 5 from both sides of our equation.

61-5=8x+5-5

56=8x

Let us divide both sides of our equation by 8.

\frac{56}{8}=\frac{8x}{8}

7=x

Therefore, Beatrice babysit 7 hours the daughter.

Expression for part c is missing.
