work out the perimeter of the triangle when the sides are : 3x-5 2x 19-x
Answer:
4x + 14
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of its three sides.
The sides of the triangle are 3x-5, 2x, and 19-x.
Calculate their sum.
3x - 5 + 2x + 19 - x
Rearrange.
3x + 2x - x + 19 - 5
Add or subtract like terms.
4x + 14
The perimeter of the triangle is 4x + 14.
Answer:
The perimeter of the triangle is 4x+14
Step-by-step explanation:
Perimeter is sum of all sides.
So,
=> 3x-5+2x+19-x
=> 5x-x-5+19
=> 4x+14
So, The perimeter of the triangle is 4x+14
What are the six digit grid coordinates for spot elevation 210
An LCD TV costs $459.95. What will the total cost be with 8.25% sales tax? (You must round to the nearest cent.
Answer:
$497.90
Step-by-step explanation:
8.25% sales tax becomes 0.0825 as a decimal fraction.
Then the total cost would be $459.95 plus 0.0825($459.95), or, in more compact form,
Total Cost = (1.0825)($459.95) = $497.90
The factor tree for 3,025 is shown. A factor tree starts with 3,025 at the top. 3,025 branches down to 5 on the left and 605 to the right. 605 branches down to 5 on the left and 121 on the right. 121 branches down to 11 on the left and 11 on the right. What is the simplest form of StartRoot 3,025 EndRoot? 16 55 52(112) 52+(112)
Answer to your query is provided below in the image
In this exercise we have to have knowledge about divisibility in this way we find that:
[tex]3025 \ is \ 5^2(11)^2[/tex]
Knowing that divisibility is the ability of a number to decrease its value, we calculate that:
[tex]3025/5=605\\605/5=121\\121/11=11\\11/11=1\\=5^2(11^2)[/tex]

On the farm, there were 2 types of animals, Pigs and Chickens. The farm had a total of 10 animals. one day he counted 34 legs. He immediately
calculated the number of chickens. How many chickens were there?
Answer:
3
Step-by-step explanation:
since he said he counted 34 legs.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34. you should first remove 2 from 34 that would give you 32. 32 divided by 4 which is the number of legs a single pig has is 8, 8 plus 2 divided by two which is the number of legs a single chicken has is 1 so I plus 8 is 9, but they said he has 10 animals, then you remove 4 again reducing the pig side to 28 and increasing the chicken size to 6. 28 divide by 4 is 7, and 6 divided by 2 is 3, so 3 plus 7 is 10, and ten is the number of animals, so the number of chicken is 3.

2 3 4 cups of oatmeal and makes one dozen muffins. If he makes 3 dozen muffins for a club meeting and 2 1 2 dozen muffins for a family reunion, how much oatmeal will he use?
Answer:
15 1/8 cups of oatmeal will be used
Step-by-step explanation:
Firstly, we shall be calculating the total number of dozens of muffin made
That would be the addition of the dozens of muffin made for the family reunion and that made for the club meeting = 3 + 2 1/2 = 5 1/2 or simply 5.5 dozens
Now, from the question initially, 2 3/4 or simply 2.75 cups of oatmeal makes 1 dozen muffins
x cups of oatmeal = 5.5 dozens of muffin
x * 1 = 2.75 * 5.5
x = 15.125 cups of oatmeal or simply 15 1/8 cups of oatmeal

Find the volume of x in the triangle shown below
Answer:
x = 109°
Step-by-step explanation:
Utilise the fact that angles in a triangle add up to 180 so,
→ Form an equation
x + 23 + 48 = 180
→ Simplify
x + 71 = 180
→ Minus 72 from both sides to isolate x
x = 109°
Answer:
109°
Step-by-step explanation:
x+48+23=180
x=180-71
x=109°Hey can you help a fella out?

Step-by-step explanation:
Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20
a cup. Which inequality can you use to find the number of cups of yogurt Monica can buy?
Answer:
$2.50 + $1.20x [tex]\leq[/tex] $20
Step-by-step explanation:
Monica needs to buy a gallon of milk ($2.50), but she also wants to buy yogurt which is $1.20 each. However, her total cost has to be under $20, and she doesn't know how much yogurt she can get. So the number of cups of yogurt is unknown, so it is represented by the variable x. Now, the milk and the unknown number of cups of yogurt must be less than or equal to $20.

Answer:
All numbers divisible by 9 are also divisible by 3.
Step-by-step explanation:
Nine is basically just 3 3's.
Please help with this question.
Answer:
Step-by-step explanation:
The first thing we have to do is find the measure of angle A using the fact that the csc A = 2.5.
Csc is the inverse of sin. So we could rewrite as
[tex]\frac{1}{sinA}=2.5[/tex] or more easy to work with is this:
[tex]\frac{1}{sinA} =\frac{2.5}{1}[/tex]
and cross multiply to get
2.5 sinA = 1 and
[tex]sinA=\frac{1}{2.5}[/tex] which simplifies to
sin A = .4
Using the 2nd and sin keys on your calculator, you'll get that the measure of angle A is 23.58 degrees.
We can find angle B now using the Triangle Angle-Sum Theorem that says that all the angles of a triangle have to add up to equal 180. Therefore,
angle B = 180 - 23.58 - 90 so
angle B = 66.42
The area of a triangle is
[tex]A =\frac{1}{2}bh[/tex] where h is the height of the triangle, namely side AC; and b is the base of the triangle, namely side BC. To find first the height, use the fact that angle B, the angle across from the height, is 66.42, and the hypotenuse is 3.9. Right triangle trig applies:
[tex]sin(66.42)=\frac{h}{3.9}[/tex] and
3.9 sin(66.42) = h so
h = 3.57
Now for the base. Use the fact that angle A, the angle across from the base, measures 23.58 degrees and the hypotenuse is 3.9. Right triangle trig again:
[tex]sin(23.58)=\frac{b}{3.9}[/tex] and
3.9 sin(23.58) = b so
b = 1.56
Now we can find the area:
[tex]A=\frac{1}{2}(1.56)(3.57)[/tex] so
A = 2.8 cm squared
Find the difference (9x2 + 3x – 2) + (3x2 – 5x – 3) Please show work so I can see what I was doing wrong. Thanks
Answer:
Adding the x² terms gives us 9x² + 3x² = 12x², combing the x terms gives us 3x - 5x = -2x and -2 - 3 = -5 so the answer is 12x² - 2x - 5.
Answer:
12x²- 2x -5
Step-by-step explanation:
actually this is the sum
(9x² + 3x – 2) + (3x² – 5x – 3)=
9x² + 3x – 2 + 3x² – 5x – 3=
(9+3)x² + (3-5)x- 5 = 12x²- 2x -5
