What is the value of x when 4v=x??
Answer:
4v
Step-by-step explanation:
The value of x is already known (x=4v) so if it is a trick question then just know its already there. If it was 4=xv then x would be 4/v but obviously it's not asking that... If you were looking for the value of v it would be x/4...
y= 3/4x
5/2x + 2y = 5
Answer:
x = 5/4
y = 15/16
Step-by-step explanation:
substitute 3/4x for 'y' in the 2nd equation
5/2x + 2(3/4x) = 5
multiply each side by 4 to eliminate fractions:
10x + 6x = 20
16x = 20
x = 20/16 or 5/4
y = 3/4 · 5/4
y = 15/16

How many square inches of canvas did rafe and Ashley use to make the lamp?
Answer:
Impossible to solve this problem with the info given
Step-by-step explanation:
The altitude of the triangle is 20.1 according to the drawing. That is a leg of the right triangle and 18 is the length of the hypotenuse. But, the hypotenuse of a right triangle must be longer than either leg. So, the 20.1 in the drawing must be incorrect. Or the 18 is incorrect.
Please help me solve this

What is the length of the missing leg ?
Answer:
A=4
Step-by-step explanation:
you use the Pythagorean Theorem,
a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.
Here is how I solved for Leg a using the Pythagorean Theorem.
Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]
Leg a = sqrt[ (5)2 - (3)2 ]
Leg a = sqrt[ 25 - 9 ]
Leg a = sqrt[ 16 ]
Leg a = 4
An observer on a cliff 1000 yards above sea level sights two ships due east. The angles of depression from the observers perspective of the ships are 54 degrees and 35 degrees. Find the distance between the two ships. Round to the nearest hundredth yard.
Answer:
480.53 yards
Step-by-step explanation:
cos(35) = 1000/hypotenuse1 - multiply by h (hypotenuse)
(h1)cos(35) = 1000 - divide by cos(35)
h1 = 1000 / cos(35)
h1 = 1220.7746
Same thing with the angle of depression of 54 degrees.
h2 = 1000 / cos(54)
h2 = 1701.3016
h2 - h1 = 480.53

Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

Name the form of the equation, then find the y-intercept of the following lines.....
y=2/5x+1
Answer:
y = 1
Step-by-step explanation:
To find the y-intercept (s), substitute in 0 for x and solve for y.
y = 2/5 x (0)+1
y-intercepts (0, 1)

−104=4x−4(2x+16)
I need a whole number i keep messing up
Answer:
x=10
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
use the distributive property
−104 = 4x − 4(2x + 16)
-104 = 4x - 8x - 64
-104 = -4x - 64
+64 +64
-40 = -4x
divide by -4
x = 10
Simplify the expression using the distributive property. -15(v - 4)
Answer: -15v-60
Step-by-step explanation:
Answer:
-15v+60
Step-by-step explanation:
multiply -15 x V and then multiply -15 x 4 which is -60. You have to change the - to + because a negative minus a negative equals a positive.
Someone help please and make sure the answer is right :)
Answer:
x=-8
Step-by-step explanation:
x+53=45
subtract 53 from both sides:
x+53-53=45-53
Simplify:
x=-8
Answer:
- 8°
Step-by-step explanation:
x + 53° = 45° { being alternate angles }
x = 45° - 53°
x = - 8 °

Si in spanish is yes and no in spanish is no
do y’all know this one?
Step-by-step explanation:
For first triangle,
sin 45 = 3 / d
1 / root 2 = 3 / d
d = 3 root 2
For second triangle,
tan 60 = 7 / a
root 3 = 7 / a
a = 7 / root 3

how do you convert 7/6 into a mixed number or how do you covert fractions into a number in general.
Answer:
1 1/6
Step-by-step explanation:
You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6
7/6 -6/6= 1 1/6
Answer:
7/6 would be 1 1/6
Step-by-step explanation:
To make it a number in general turn into a decimal.

Give the largest whole number that could equal the length of the side in the picture.
Answer:
8
Step-by-step explanation:
We can use triangle inequality, let AC = x:
x+4 > 5
x+5 > 4
9 > x
Simplifying:
x>1
x>-1
9>x
Thus: 9>x>1
So the Largest whole number is 8
Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following acute, right or obtuse. Please help and thank you
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.
The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.
The triangle is obtuse.
__
Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).
In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:
hypotenuse = √(6² +8²) = √100 = 10
Your long side is longer, so your largest angle is larger than 90°.
Law of Cosines:
angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°
