Brenda had bowling scores of 92, 110, 85, 78, and 96. She completed the steps below to determine the score she needs in her next

Yakvenalex [24]

Answer:

Hence final answer is B: Step 2.

Step-by-step explanation:

Step 1: Find the total points needed to score in six games: 96x6=576

Justification:

Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.

Step 2: Find the total points scored: 92+110+85+78=365

Justification:

Sum of total points scored by Brenda is 92+110+85+78= 461.

But she got different value 365.

Hence step 2 is wrong.

Hence final answer is B: Step 2.

Jaden is flying a kite with an angle of elevation of 33 degrees. If Jaden lets out 275 feet of string, how high above the ground

pshichka [43]

Answer:

149.8 feet

Step-by-step explanation:

θ = Angle of elevation = 33°

The length of string Jaden lets out = Hypotenuse = 275 feet.

How high above the ground that the kite is flying = Opposite Side.

We are solving this question using the Trigonometric function of Sine

Sin θ = Opposite Side/Hypotenuse

Sin 33 = Opposite/275 feet

Cross Multiply

Sin 33 × 275 feet = Opposite

Opposite side(Height ) = 149.77573463 feet

Approximately to the nearest tenth = 149.8 feet

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length

rosijanka [135]

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

$Perimeter = 50$

$a=b + 1$

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

$Perimeter = 2(a + b)$

Make b the subject in $a=b + 1$

$b = a -1$

Substitute a - 1 for b and 50 for Perimeter in $Perimeter = 2(a + b)$

$50 = 2(a + a - 1)$

Divide through by 2

$25 = a + a - 1$

$25 = 2a- 1$

Add 1 to both sides

$25 + 1 = 2a - 1 +1$

$25 + 1 = 2a$

$26 = 2a$

Solve for a

$a = 26/2$

$a = 13$

Hence, the length of the longest side is 13mm
