Answer:
125.9
Step-by-step explanation:
To round 125.892 to the nearest tenth consider the hundredths’ value of 125.892, which is 9 and equal or more than 5. Therefore, the tenths value of 125.892 increases by 1 to 9.
125.892 rounded to the nearest tenth = 125.9
Answer: 283
Step-by-step explanation:
To find the median, you have to first arrange the figures in the distribution in ascending order:
210, 249, 316, 443
As this is an even distribution, the Median will be found by adding up the second and third numbers and then dividing by 2:
= (249 + 316) / 2
= 283
Answer:
It is already at its simplest form and nothing further can be done.
Step-by-step explanation:
Answer:
16 presents
Step-by-step explanation:
Since you know that one present is 3 cm of tape, if he used a total of 48 cm, you can divide 48 into 3 to get 16 presents.
Answer:
∠QDP = 34°
Step-by-step explanation:
The complete question is shown in the image attached.
In triangle ABC, ∠ABC = 90° and ∠BCA = 28°. Hence:
∠CAB + ∠ABC + ∠BCA = 180° (sum of angles in a triangle)
∠BCA + 28+ 90 = 180
∠BCA + 118 = 180
∠BCA = 180 - 118
∠BCA = 62°
Also ∠DCA + ∠BCA = 90° (Each angle in a rectangle is 90°)
∠DCA + 62 = 90
∠DCA = 90 - 62 = 28°
∠DAC + ∠BAC = 90 (angle in a rectangle)
∠DAC + 28 = 90
∠DAC = 90 - 28 = 62°
In triangle ADQ, ∠DQA = 90° and ∠QAD = 62°. Hence:
∠QAD + ∠ADQ + ∠QAD = 180° (sum of angles in a triangle)
∠ADQ + 62+ 90 = 180
∠ADQ + 152 = 180
∠ADQ = 180 - 152
∠ADQ = 28°
In triangle DPC,DP = PC, hence ∠PDC = ∠DCP= 28°.
∠PDC + ∠ADQ + ∠QDP = 90° (angle in a rectangle)
28 + 28 + ∠QDP = 90
∠QDP + 56 = 90
∠QDP = 90 - 56
∠QDP = 34°
