Answer:
93.7 miles
Step-by-step explanation:
This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.
We need to find the hypotenuse. We can use Pythagoras rule:
[tex]hyp^2 = opp^2 + adj^2[/tex]
where opp = opposite side to the angle considered
adj = adjacent side to the angle considered
This implies that:
[tex]x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles[/tex]
The car is 93.7 miles far from its starting point.
The ratio x:y is 3: 1 Which of the following statements is correct? A x is 3/4 of y B y is 1/3 of x C x is 1/3 of y D y is 1/4 of x
Answer: i say B is correct
Answer:
B --> y is 1/3 of x
Step-by-step explanation:
x:y is 3:1
=> x is bigger than y
=> x is 3x bigger than y
=> x = 3 lots of y
=> [tex]x = 3y[/tex]
=> [tex]\frac{x}{3} = y[/tex]
=> [tex]\frac{1}{3} x = y[/tex]
Therefore y is [tex]\frac{1}{3}[/tex] of x
This means that B is correct

today only, a sofa is being sold at a 36% discount. The sale price is $560. what was the price yesterday?
Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560
[tex]\frac{64}{100}*x=560\\\\x=560*\frac{100}{64}\\\\x=875[/tex]
Yesterday's price = $ 875
What are the solutions to the expression 4x2+11x−3
Step-by-step explanation:
4x² + 11x - 3 = 0
(4x-1)(x+3) = 0
x = 1/4, -3
Answer:
x = -3 or x = 1/4
Step-by-step explanation:
Please see the graph in the attachment.
4 x^2 + 11 x - 3= 0
4 (x + 3) (x - (1/4)) = 0
(x + 3)= 0 or (x - (1/4))= 0
x = -3 or x = 1/4

Find the volume of a pyramid with a square base, where the perimeter of the base is
5
in
5 in and the height of the pyramid is
3.6
in
3.6 in. Round your answer to the nearest tenth of a cubic inch.
ANSWER:
1.9
EXPLANATION:
Volume of a pyramid = V= lwh/3
V= Volume
L= Length
W= Width
to get length we divide 5 by 4 which is 1.25
therefore V= 1.25×1.25×3.6/3
V= 1.89
1.89 to the nearest tenth is 1.9

Answer:
Step 1: 1,000, Step 2: 1,000, Step 3: 30,000
Step-by-step explanation:
For the first step all you have to do is find out what times 5 is equal to 5000.
[tex]5*x=5000\\[/tex]
Then for the second one all you have to do is keep the same 1000, because:
[tex](5*6)*1000=30*1000[/tex]
It's the same thing.
Afterwards you can just assume that you'll have 30000 as your answer because multiply 30 by 1000 will give, 30 thousands.
[tex]30*100=30000[/tex]

Given that ZBCD and ZBCA form a straight angle, if ZABC measures 55
degrees and ZBCD measures 60 degrees, then the measure of ZBAC is
degrees.
Answer:
Angle BAC is 5 degrees.
Step-by-step explanation:
It's easiest if you just annotate you diagram as you find each angle. You can do this in lots of different ways, but this is how i got there.
So to find BAC, you need to find ABC and BCA. After you find these two, its just a matter of subtraction, which is simple.
We already know ABC = 55 degrees.
So now we have to find BCA:
1) They told us that BCD is 60 degrees and that its sitting on a straight line
2) From this we can find that BCA is 120 degrees, because a straight line is 180 degrees. 180 -60 = 120 degrees.
Now that we have both ABC and BCA, we can find BAC:
1) The angles of all triangles add up to 180 (idk why, its just how it is)
2) So, if we do 180 - BCA - ABC, we should get BAC
3) So, 180 - 55 - 120 = 5 degrees
Sorry if the explanation was really long, its a bit weird to explain it all in words. Hope it helped : )
Consider the triangles. Triangle G H I. Side G H is 16 inches, H I is 15 inches, G I is 10 inches. Angle G is 65 degrees, H is 48 degrees, I is 67 degrees. Triangle D E F. Side D E is 3 inches, E F is 3.2 inches, D F is 2 inches. Angle D is 67 degrees, E is 48 degrees, F is 65 degrees. What can be concluded about these triangles? Check all that apply. The corresponding angles are proportional. The ratios of the corresponding sides are equivalent. The corresponding sides are congruent. The corresponding angles have the same measure. DE corresponds to IH.
Answer:
The triangles are Similar Triangles
Step-by-step explanation:
The corresponding angle are NOT proportional
The ratios of corresponding sides ARE equal.
The corresponding sides are NOT congruent.
The corresponding angle HAVE same measure
Two triangles are said to be similar triangle when they have the same shape but not necessarily the same size.
Which means that if two triangle have there corresponding angles congruent, and if there corresponding sides are in ratio, they are considered as Similar Triangle.
Corresponding angle:
∠H = ∠E
∠G = ∠F
∠I = ∠D
All angle are congruent
Ratio of Corresponding sides:
16/3.2 : 15/3 : 10/2
5:5:5

What is a Quadratic equation and its solution?A quadratic equation in the variable x is an polynomial of degree 2 equation of the form ax²+bx+c = 0 where a, b, c are real numbers a≠0. For example, 2x²-3x+1 =0. And we say that x=α is an solution of a quadratic equation if α satisfies the equation and since its degree is two it will always have 2 solutions which may be real or Imaginary.
Given equation here is : x² -8x+16= 0
x²-2.4x+4²=0
(x-4)²=0
x=4,4
Hence, the quadratic equation has two equal and real solutions.
