How many yards are in 3 times of 4 yards 2 foot
Len [333]
4 yards and 2 feet is equal 14 feet since each yard is made up of 3 feet.

1 yard = 3 feet.

So if we take 14 feet and multiply that by 3 we get 42 feet. 

42/3 is equal to about 14 yards in total 

So the answer is 14 yards.

¿cuál es el vértice de una parábola que corta los ejes en los puntos (-1,0) , (5,0), (0,-10) ?​
kvasek [131]

Answer:

vertex: (2,-18)

Step-by-step explanation:

y = ax² + bx + c

(-1,0) : a - b + c = 0       ...(1)

(5,0) : 25a +5b +c = 0  ...(2)

(0,-10): 0a + 0b + c = -10        c=-10

(1) x5: 5a - 5b + 5c = 0  ...(3)

(2)+(3): 30a + 6c = 0          30a = -6c = 60        a = 2

(1): 2 - b -10 = 0     b = -8

Equation: y = 2x² - 8x -10 = 2 (x² -4x +4) - 18 = 2(x-2)² -18

equation: y = a(x-h)²+k     (h,k): vertex

vertex: (2,-18)

If mAngle3 = 29°, what is mAngle4?
kondor19780726 [428]

Please consider the attached graph.

We have been given that measure of angle 3 is 29°. We are asked to find the measure of angle 4.

Upon looking at our diagram, we can see that angle 3 and angle 4 are linear angles.

We know that linear angles add up-to 180 degrees, so the sum of measure of angle 3 and angle 4 will be 180 degrees.

m\angle 3+m\angle 4=180^{\circ}

29^{\circ}+m\angle 4=180^{\circ}

29^{\circ}-29^{\circ}+m\angle 4=180^{\circ}-29^{\circ}

m\angle 4=151^{\circ}

Therefore, the measure of angle 4 is 151 degrees.
