In triangle XYZ, mZZ > mZX + mZY. Which must be true about AXYZ?
mZX + m2Z < 90°
mZY > 90°
ZX and Y are complementary
mZX + mZY < 90°

Answers

Answer 1

Answer:

D. m∠X + m∠Y < 90°

Step-by-step explanation:

GivenΔXYZ with m∠Z > m∠X + m∠YOptions

m∠X + m∠Z < 90°

incorrect, the sum of these two angles should be > 90°

m∠Y > 90°

incorrect, it should be < 90°

∠X and ∠Y are complementary

incorrect as angle Z is greater that the sum of angles X and Y, then sum of three angles would be greater than 180°

m∠X + m∠Y < 90°

correct, this is the only possible option

In a certain​ chemical, the ratio of zinc to copper is 3 to 14. A jar of the chemical contains 406 grams of copper. How many grams of zinc does it​ contain?

Answers

The chemical contains 87 grams of zinc and 406 grams of copper

Ratio

Ratio is the the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. It indicates how many times one number contains another.

The ratio of zinc to copper is 3 to 14. Hence let x represent the total amount of the chemical. For 406 grams of copper:

(14/17)x = 406x = 493 grams

Amount of zinc = (3/17) * 493 = 87 grams

The chemical contains 87 grams of zinc and 406 grams of copper

The length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if its area is 140 square centimeters?

Answers

Answer:

Dimensions = 7 cm by 20 cm.

Step-by-step explanation:

Let the length and width of the rectangle be L & W respectively.

Given the following data;

Area of rectangle = 140 cm²

L = W - 13

To find the dimensions of the rectangle;

The area of rectangle = L * W

Substituting into the above formula, we have;

140 = L * W

140 = (W - 13) * W

140 = W² - 13W

W² - 13W - 140 = 0

Solving the quadratic equation using factorization method;

Factors are -20 and 7

W² - 20W + 7W - 140 = 0

W(W - 20) + 7(W - 20) = 0

(W - 20)(W + 7) = 0

W - 20 = 0

W = 20

W + 7 = 0

W = -7

Thus, W = 20 or -7

But the width has to be positive, W = 20 centimeters.

Next, to find the length of rectangle

L = W - 13

L = 20 - 13

L = 7 centimeters.

Step-by-step explanation:

First we calculate the obvious square without the extra points. The side length of the square is four; therefore, the area of the square is 16 square units. The points are each 1 square unit as they split the squares down the midde. In total, 16 + 4(1) = 20.

Solve this equation h + 17 = 40

Thanks!

Answers

Answer:

H= 40-17

H= 53

Therefore, h=23

Answer:

h=23

Step-by-step explanation:

Since h plus 17 is equal to 40, h needs to be a number that adds to 17 to get 40. Therefore, you can subtract 17 from 40 to get 23. If you add it into the equation you get 23+17=40 which is correct.

Answer:

A. About 9.4 units

Step-by-step explanation:

Suppose you are a witness to a nighttime hit-and-run accident involving a taxi in Athens. All taxis in Athens are blue or green. You swear, under oath, that the taxi was blue. Extensive testing shows that, under the dim lighting conditions, discrimination between blue and green is 75% reliable (i.e., if the taxi was green, it appears green to you 75% of the time, and blue otherwise; similarly, if the taxi was blue, it appears blue to you 75% of the time, and green otherwise).

Required:
a. Is it possible to calculate the most likely color for the taxi? (Hint: distinguish carefully between the proposition that the taxi is blue and the proposition that it appears blue.)
b. What if you know that 9 out of 10 Athenian taxis are green?

Answers

Answer:

A ) Yes it is possible

B) The color of the most likely taxi to hit the victim is Green in color because

P( Tg / Yb ) = 0.75 = 75%

Step-by-step explanation:

A) Yes it is possible

attached below is a proposition that can be used to calculate the most likely color of the taxi

where: Tg = taxi is green

            Tb = Taxi is blue

            Yg = green taxi is seen

            Yb = blue taxi is seen

B) When 9 out of 10 Athenian taxis are green

The color of the most likely taxi to hit the victim is Green in color because

P( Tg / Yb ) = 0.75 = 75%

A. 10n+30<500

B. 10n+30≥500

C. 30n+10≤500

D. 30n+10>500

Answers

Answer:

The correct answer is 10n ≥ 470.

Step-by-step explanation:

Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.

They already collected 30 canned goods, therefore we can subtract this quantity from out goal.

500 - 30 = 470

Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.
