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
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.
4. Twice the larger of two numbers is three more than five times the smaller. The sum of four times the larger and three times the smaller is
71. What are the numbers?
Answer:
Smaller is 5, larger is 14
Step-by-step explanation:
y is larger, x is smaller
2y = 3 + 5x
4y + 3x = 71
Let's solve for y in the first one, then substitute that into the second one.
y = 3/2 + 5/2x
4(3/2 + 5/2x) + 3x = 71
12/2 + 20/2x + 3x = 71
6 + 10x + 3x = 71
13x = 65
x = 5
Substitute that in to the first equation:
2y = 3 + 5(5)
2y = 3 + 25
2y = 28
y = 14
check those answers in the second equation
4y + 3x = 71
4(14) + 3(5)
= 56 + 15 =71

Converting from vertex form to standard form
[tex]y = \frac{1}{2} (x - 2) {}^{2} - 4[/tex]
Answer:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]
Step-by-step explanation:
To convert from vertex form to standard form, we can simply expand.
So, we have:
[tex]\displaystyle f(x)=\frac{1}{2}(x-2)^2-4[/tex]
Expand the square:
[tex]\displaystyle f(x)=\frac{1}{2}(x^2-4x+4)-4[/tex]
Distribute:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x+2-4[/tex]
Simplify:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]
someone please answerrrrrr
someone pls help:>>
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

In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice
now?
Janice is currently 4.
In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.

Rebecca is climbing up a 500-foot cliff. By 1:00 P.M., she has
climbed 125 feet up the cliff. By 4:00 P.M., she has reached
an altitude of 290 feet. Find the average rate of change in
Rebecca's altitude during the three hours. Give the rate in feet
per bour.
Answer:
Step-by-step explanation:
(290 ft - 125 ft)/(3 hours) = (165 ft)/(3 hours) = 55 ft/hour
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...

How could writing a problem using an exponent be easier to understand than repeated multiplication?
Answer:
One reason, is because it clearer and easier to read.
Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.
3 is the number being multiplied, and 5 tells you how many times.

−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
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°
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 °

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
which number when rounded to the nearest tenth is 43.6

jackie leaves the house to meet her friend at the park. she walks 1 mile west and 2.5 miles north. how many miles is the quickest way back for jackie from her starting point
Answer:
2.5 miles west and 1 mile north
Step-by-step explanation:
The point (2.5, 1) is also on the line. What is the vertical change between (2.5, 1) and (5, 2)? What is the horizontal change?
Answer:
In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.
then if we have the points (a, b) and (c, d)
The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.
Then the vertical change between the points (2.5 , 1) and (5, 2) is:
2 - 1 = 1 unit.
The horizontal change between the points (2.5, 1) and (5, 2) is:
5 - 2.5 = 2.5 units.
