What is length of BW using what you know? DONT GIVE ME A LINK JUST ANSWE PLEASEE (will give brainlist)
Answers
Answer:
The length of BW is [tex]105\sqrt{2}[/tex], or about 148.49.
Step-by-step explanation:
For this problem, we will assume that the figure is a square. We will call the figure "Figure BOWL".
Because figure BOWL is a square, we know that the lengths of each sides of the square are equal, so the length of each side is 105.
Notice that the BW, OB, and WO make a triangle. We'll call it triangle BOW. Since figure BOWL is a square, we know that angle BOW is 90°, and so triangle BOW is a right triangle.
Since triangle BOW is a right triangle, we can solve for BW using the Pythagorean theorem, [tex]a^{2} + b^2 = c^2[/tex]. "a" and "b" are the legs of the triangle, while "c" is the hypotenuse of the triangle.
In triangle BOW, the legs are OB and WO, while the hypotenuse is BW.
Plug in the values for the equation and solve.
[tex]a^2 + b^2 = c^2[/tex]
[tex]OB^2 + WO^2 = BW^2[/tex]
[tex]105^2 + 105^2 = BW^2[/tex]
[tex]11,025 + 11,025 = BW^2[/tex]
[tex]22,050 = BW^2[/tex]
[tex]\sqrt{22,050} = BW[/tex]
We can either use the estimated value, or the exact simplified value of [tex]\sqrt{22,050}[/tex].
Here is the exact simplified value:
[tex]\sqrt{22,050} = \sqrt{25 * 882} = \sqrt{25 * 9 * 98} = \sqrt{25 * 9 * 49 * 2} = \sqrt{5^2 * 3^2 * 7^2 * 2} = (5 * 3 * 7)\sqrt{2} = 105\sqrt{2}[/tex]
BW = [tex]105\sqrt{2}[/tex]
For the estimated value, just use a calculator:
[tex]\sqrt{22,050}[/tex] ≈ 148.49
BW ≈ 148.49

how many 1/2 cups to make 3/4 of a cup?
Answers
We are required 1.5 half cups to form the required fraction of a cup.
What is a fraction?The upper part of a fraction is numerator and the lower part is denominator.
How to find the fraction?We are told to make 3/4 of a cup from1/2 of cup so let the number of times we need half of a cup be x
So
1/2 * x=3/4
x=3/2 which means 1.5
So we need 1.5 times the half cup to make 3/4 of a cup.

If you get that right, follow Sammy Revv on Spotify!
Answer:
The three of them are similar.
Step-by-step explanation:
1- Triangle A and Triangle B have two same angles, 37° and 47°, which means the two angles are congruent. According to the Angle Angle Theorem (AA), in two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar.
2- First, place both triangles correctly. When you do it, you'll notice that 24≅12, 32≅16, and 9≅4.5:
24/12 = 2 ✓ 32/16 = 2 ✓ 9/4.5 = 2 ✓According to Side-Side-Side Theorem (SSS), if the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.
3- Here, the triangle shows in each one two different angles, sharing only one which is 55°. To know if they are congruent, you can add the two different angles that show both triangles, 72° and 53°, with the 55°. If it gives 180, it means the can be congruent:
55°+72°+53 = 180° ✓Part B at 10:00 a.m., lin's was 7 meters. Add this point to the graph

You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years. How much will your $1,900 be worth in 3 years?
Answers
Answer:
FV= $2,139.71
Step-by-step explanation:
Giving the following information:
You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years.
First, we need to calculate the semiannual interest rate:
Semmi-annual interest rate= 0.04 / 2= 0.02
To calculate the future value, we need to use the following formula:
FV= PV*(1 + i)^n
PV= $1,900
i= 0.02
n= 2*3= 6 semesters
FV= 1,900*(1.02^6)
FV= $2,139.71

x = 18
Step-by-step explanation:
Vertically opposite angles are equal.
x + x + x + 90 = 144
3x + 90 = 144
Subtract 90 from both sides
3x = 144 - 90
3x = 54
Divide both sides by 3
x = 54/3
x = 18
Arquimedes, Euclides e Ptolomeu têm, juntos, R$ 1 990,00. Arquimedes possui R$ 190,00 a mais do que Euclides e esse, dispõe de R$ 120,00 a mais do que Ptolomeu. Determine quantos reais cada um deles possui.
Answers
Responder:
Ptolomeu = 520
Euclides = 640
Arquimedes = 830
Explicação passo a passo:
Deixar :
Quantidade que Ptolomeu tem = x
Quantidade de Euclides = x + 120
Quantidade que Arquimedes tem = x + 120 + 190
Valor total que todos eles têm = $ 1990
Portanto,
x + x + 120 + x + 120 + 190 = 1990
3x + 430 = 1990
3x = 1990 - 430
3x = 1560
x = 520
Ptolomeu = 520
Euclides = 520 + 120 = 640
Arquimedes = 640 + 190 = 830
