Goals scored by a hockey team in successive matches are 5,7,4,2,4,0,5,5 and 3. What is the number of goals, the team must score
Stels [109]

Answer:

5

Step-by-step explanation:

Total goals /total no. of matches = 4

5+7+4+2+4+0+5+5+3+x / 10 = 4

35 + x = 4 × 10

x = 40 - 35

x = 5

So, the team must score 5 inorder to get the average of 4 goals per match.

serious [3.7K]

Answer:

m∠PRT = 114°

m∠T = 37°

m∠RPT = 29°

Step-by-step explanation:

This question is incomplete (without a picture) ; here is the picture attached.

In this picture, an airplane is at an altitude 12000 feet.

When the plane is at the point P, pilot can observe two towns at R and T in front of plane.

We have to find the measure of ∠PRT, ∠T and ∠RPT.

Form the figure attached segment PS is parallel to RT and PR is a transverse.

We know that internal angles formed on one side of the parallel lines by a transverse are supplementary.

Therefore, x + 66 = 180

x = 180 - 66 = 114°

∠PRT = x = 114°

m∠RPT = m∠SPR - m∠SPT

             = 66 - 37

             = 29°

Since m∠PRT + m∠T + m∠RPT = 180°

114 + ∠T + 29 = 180

143 + ∠T = 180

∠T = 180 - 143

∠T = 37°

Determine the value of a so that A = 2i+aj+k and B = 4i-2j-2k are perpendicular​
Digiron [165]
In order to make them perpendicular, their dot product must result in zero. so:

4 \times 2 - 2a - 2 \times 1 = 0

2a = 8 - 2 = 6

a = 3

Find the distance between (2,4) and (12, 9) on a coordinate plane. round to the nearest tenth if necessary. *
atroni [7]
Use pythagoras

d = √(Δx² + Δy²)
d = √(12-2)² + (9-4)²
d = √(10² + 5²)
d = √(100 + 25)
d = √125
d = 5√5
d = 5 × 2.236
d = 11.18

The nearest tenth is 11.2, so the distance is near to 11.2
