Solve for b pythagorean theorem! someone plz help meeeee
Answer:
3
Step-by-step explanation:
Since we already know c, so we need to find b.
c² = a² + b²
5² = 4² + b²
b² = 5² - 4²
b² = 25 - 16
b² = 9
b = 3

Answer:
Ruffly 6.5
Step-by-step explanation:
a^2+b^2=C^2
In this case we need to find a so we do c^2-b^2.
9.8^2-7.3^2=42.75
Square root of 42.75 is ruffly 6.5
Answer:
6.5 km
Step-by-step explanation:
hypotenuse (h)=9.8km
base(b)=7.3km
perpendicular (p)=?
we know,
p^2 =h^2-b^2
p^2=(9.8)^2-(7.8)^2
p^2= 96.04-53.29
p^2=42.75
(p)^2=(6.5)^2
p=6.5km
solve for x!........
Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
11x + 2 is an exterior angle of the triangle, then
11x + 2 = 5x + 10 + 58
11x + 2 = 5x + 68 ( subtract 5x from both sides )
6x + 2 = 68 ( subtract 2 from both sides )
6x = 66 ( divide both sides by 6 )
x = 11

The sales tax on clothing in Louisiana is 4% . Calculate how much tax you need to pay on a dress if it costs $19.50 before before tax. Round your answer to the nearest cent.
Answer:
.78 cents
Step-by-step explanation:
To find the tax amount on any number, divide that number by 100 and then multiple it by the tax percentage.
In this case that would look like: $19.50/100 times 4 =.78

Answer:
1.V=288, A=288
2. V=460, A=494
3. V=672
4. A=898
Step-by-step explanation:
1.
V= l×b×h
288
A=2(lb+lh+bh)
=288
2.
V¹= larger cuboid =320
V²=smaller cuboid=140
V=460
A¹=328
A²=166
A=494
3.
V=(Area of cross section)×length
=672
4.
Area of cube=l³
³√294=6.65
add 3
9.65³=898

A line passes through the point (-2,7) and has a slope of -5
Answer:
y - 7 = -5(x + 2) a = -1Step-by-step explanation:
The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = -5
(-2, 7) ⇒ x₁ = -2, y₁ = 7
y - 7 = -5(x - (-2))
y - 7 = -5(x + 2)
(a, 2) ⇒ 2 - 7 = -5(a + 2)
-5 = -5a - 10
5a = 5 - 10
5a = -5
a = -1

Max has sticks of lengths 6, 7, 8, and 10 inches. He wants to make a right triangle for an art project. Which 3 sticks should he use? 6 in., 7 in., and 8 in. 6 in., 7 in., and 10 in. 6 in., 8 in., and 10 in. 7 in., 8 in., and 10 in.
Answer:
6in, 8in and 10in
Step-by-step explanation:
For a right angled triangle :
The hypotenus, thee longest side in The triangle should be :
Hypotenus = sqrt((opposite² + adjacent²))
The most appropriate from the option would be :
6in, 8in and 10in
Hypotenus = sqrt((6² + 8²))
Hypotenus = sqrt(36 + 64)
Hypotenus = sqrt(100)
Hypotenus = 10
Answer:
C. 6 in., 8 in., and 10 in.

The average petrol consumption of a vehicle is 1 gallon per 35 km. The cost of 1 litre of petrol is $49. Fund the cost of petrol for a journey of 280 km.
(take 1 gallon=4.5 litres)
Step-by-step explanation:
Total petrol consumption of the journey=
Total distance travelled ÷ Average petrol consumption
[tex] = 280 \div 35 \\ = 8 \: gallons[/tex]
Given 1 gallon = 4.5 litres,
[tex]8 \: gallons \: = 8 \times 4.5 \\ = 36 \: litres[/tex]
Total cost of petrol for this particular journey = Petrol consumed x cost of 1 litre of petrol
[tex] = 4.5 \times 49 \\ = 220.50 \: dollars[/tex]

The model shows 4 = 2x - 2 What value of x makes the equation true?
Answer:
You showed no model. However, looking at this equation it seems the answer would be x=3.
Step-by-step explanation:
Add 2 to both sides which leaves you with 6=2x and then divide both sides by 2 to get x=3.
Find the length of the hypotenuse?

19.7ft
Step-by-step explanation:
i just know
Answer: x=22.0 (nearest tenth)
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos, Tan.
To which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin and then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos, then the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A' is for Opposite over Adjacent.
Because we have the Adjacent (angle next to 60°) and the Hypotenuse we would be using Cos.
So first you would write:
Cos 60=11/x
Then we would have to do the inverse to 'undo' the equation to get x on it's own. This would then look like:
x Cos 60=11
Then we do the inverse again:
x=11/Cos 60
so, x=22.0 (to the nearest tenth)
Hope this helps :)
If a function is defined as y=-3x+4, find the value of the function if the input is -2
Answer:
y=10
Step-by-step explanation:
Assuming that "y" is the output and you input the -2 into the "x" variable, you would solve it like this
y=-3(-2)+4
Use order of operations
y=6+4
Add
y=10
Wich set of ordered pairs does not represent a function.
Please help.
Answer:
D.
Step-by-step explanation:
A function has to have only one y-value for every x-value. This means that D is not a function because it contains (6,2) and (6, 4), which means that there are 2 different y-values for the x-value of 6.

A bag contains 3 red marbles and 4 blue marbles. A marble is taken at random from the bag and replaced. Another marble is taken from the bag.
Work out the probability that the two marbles taken from the bag are the same colour.
Give your answer as a fraction.
Answer:
25/49
Step-by-step explanation:
probability of red and red is (3/7)(3/7) = 9/49
Probability of blue and blue is (4/7)(4/7) = 16/49
Probability of same color = prob. of red and red or prob. of blue and blue
= 9/49 + 16/49
= 25/49
