Step-by-step explanation:

34o is an acute angle which is less than 90o

LN is a secant. It cuts the circle's circumference in two places.

TP is an arc. It is related to the the two givens by

(Large Arc - Small Arc )/2 = the exterior angle

We are looking for the large arc. Call it x

Small arc = 50

Exterior angle = 34

(x - 50)/2 = 34               Multiply both sides by 2

x - 50 = 2 *34

x - 50 = 68                    Add 50 to both sides.

x = 68 + 50

x = 118

So the arc labeled TP = 118

Answer: TP = 118

Step-by-step explanation:

y more than seven = 7 + y, using associative property, 7 + y = y + 7

The correct expression is,

⇒ y + 7

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The algebraic expression is,

Answer:

Number of chirps per minute = 68

Step-by-step explanation:

Given:

​T = 50+ (N - 40)/4

where,

T is a temperature in degrees Fahrenheit

N is a number of chirps per minute

Find n when T = 57°F

​T = 50 + (N - 40)/4

57 = 50 + (N - 40)/4

57 - 50 = (N - 40)/4

7 = (N - 40)/4

Multiply both sides by 4

7 × 4 = (N - 40)/4 × 4

28 = N - 40

28 + 40 = N

68 = N

N = 68

Number of chirps per minute = 68

Answer:

d. -2 <= y <= infinity

Step-by-step explanation:

The graph starts at -2 with a solid (colored in) point on the -2. So there are no y's less than -2 on the graph.

The graph continues to go up. Yes, it goes to the right, but we are looking at the y's. There is an arrow at the right end of the graph which means it continues to go up forever.

-2 <= y <= infinity

The total number of pounds of cheese Kala bought is 1.75.

Bar graph (bar chart) is a graph that represents the categorical data using rectangular bars.

The bar graph shows the comparison between discrete categories.

Given

Kala bought two types of cheese at a deli.

She bought 0.50 pound of American cheese and 1.25 pounds of Swiss cheese.

The bar diagram and equation below represent Kala’s purchase, where p represents the total number of pounds of cheese she bought.

A bar diagram. The top bar contains p.

The bottom bars contain 0.50 and 1.25.

p = 0.50 + 1.25

The total number of pounds of cheese Kala bought is;

= 0.50 + 1.25

= 1.75

Hence, the total number of pounds of cheese Kala bought is 1.75.

Answer: Complementary angles, adjacent angles

Step-by-step explanation:

Because of vertical angles, we know that the sum of angles 1 and 2 would be equal to 90 degrees, as the measure of right anglese is 90 degrees.

A pair of angles that sum to 90 degrees are otherwise called complementary angles.

These pair of angles are also adjacent because they have a common side/vertex yet do not intersect.

They are not vertical angles because they are not opopsite of each other.

They are not supplementary angles because they don't sum to 180 degrees.
