Answer:
8, 15, 16 are not able to form a right side triangle.
Write and solve an equation to find the values of d and w .
Answer:
d = 65°
w = 55°
Step-by-step explanation:
m∠DAC +∠m∠CAB = 60
m∠DAC + 35 = 60
m∠DAC = 25
m∠DAC + d = 90
25 + d = 90
d = 65°
m∠GAF + w + d = 180
60 + w + 65 = 180
w + 125 = 180
w = 55°

As an unknown drone is detected by a radar dish hovering over a secure location in Washington dc the initial reading of the radar dish was detects the drone .The reading of the radar dish indicates an angle of elevation of 60 to the drone
Answer:
60° ; 30°
27.71 km
Step-by-step explanation:
Since we have a right angled triangle, and also the sum of the angles in a triangle is 180°
Angle of elevation is given as 60°
Hence, we have :
90°+60°+x ° = 180°
x = 180 - 150
x = 30°
The two acute angles are 60° and 30°
The altitude, h of the drone can be obtained thus :
Using trigonometry :
Sin θ = opposite / hypotenus
Sin 60 = h / 32
h = 32 * sin 60
h = 27.71 km

At Deion's boutique, 15 customers wore a size small, and 71 customers wore a different size. What is the probability that a randomly selected customer wore a size small?
Answer: 15 / 86
Step-by-step explanation:
First find out the total number of customers at Deion's boutique:
= 15 + 71
= 86 customers
Out of this 86, 15 customers wore a small size.
The odds of picking one of those 15 is:
= 15 / 86

Twice a number plus 6 times the number is 72
Answer:
9
Step-by-step explanation:
Let the no be x
By the conditions given ,
2x + 6x = 72
8x = 72
x = 72/8
x = 9
therefore the no is 9
[tex](2 \times x) + (6 \times x) = 72 \\ 2x + 6x = 72 \\ 8x = 72 \\ x = 72 \div 8 \\ x = 9[/tex]

Which is not a pair of congruent sides in the diagram below?
EF and JH
EK and GH
KJ and JH
KJ and FG
What would this expression be when simplified
Answer:
The first one is the answer
Step-by-step explanation:
Explain whether or not these triangles are congruent. Give reasons for your answers
Step-by-step explanation:
• first triangle •
the third angle = 180-56-37 = 87°
the 4 cm's side is located between angle 56° and 87°
• second triangle •
the third angle = 180-56-37= 87°
the 4 cm' side is located between angle 37° and 87°
so, both of triangles are not congruent, because the 4 cm's side is not located between the same angles
Mark uses his calculator for 80% of his maths homework
questions. Twelve questions are answered with his calculate
How many questions does Mark have for homework
Answer:
The number of questions in Mark's homework is:
60 questions.Step-by-step explanation:
To identify the number of questions of the homework, first, you must identify the percentage that is the 12 question Mark calculates by himself: if in 80% he uses calculator, in 20% he doesn't, I mean, he uses his own calculates, by this reason:
20% = 12 questions of the homework.With this data, we can use a simple rule of three and find the number of question that correspond to 80%.
If:
20% = 12 questions80% = xThen:
[tex]x=\frac{80*12}{20}[/tex] (you can use the percentage if you want, the result is the same)[tex]x=\frac{960}{20}[/tex][tex]x=48[/tex]At last, we add the 80% and the 20% of the questions:
Total of questions = 80% with calculator + 20% with his calculatesTotal of questions = 48 questions + 12 questionsTotal of questions = 60 questionsAs you can see, the number of questions in Mark's homework is 60 questions.
You have been saving $12 each week for many weeks. One day, you decide to count your savings and find that you have $384. Choose the equations that helps you find how many weeks w you have been saving.
12 384 = w
12 + w = 384
384 - 12 = w
12w = 384
Answer:
D or the last one.
Step-by-step explanation:
Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.
