Step-by-step explanation:
You can make an infinite number of triangles with those three angle measures, because the side lengths can be different.
what does m2+ m3= ???????????
Answer:
M2+m3=90
Step-by-step explanation:
Angle 1 already is equal to 90. A triangle can only go up to 180 wo the other two angles have to add up to 90.

Math is really hard
Answer:
The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]
The value of x when b is 3 is: x = -1
Step-by-step explanation:
We are given the function: [tex]-2(bx-5)=16[/tex]
First we need to find
The value of x in terms of b
We need to find value of x
[tex]-2(bx-5)=16[/tex]
Multiply -2 with terms inside the bracket
[tex]-2bx+10=16[/tex]
Subtract 10 from both sides
[tex]-2bx+10-10=16-10\\-2bx=6[/tex]
Divide both sides by -2b
[tex]\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}[/tex]
So, The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]
The value of x when b is 3
We have the equation for the value of x in terms of b:
[tex]\mathbf{x=-\frac{6}{2b}}[/tex]
Put b = 3
[tex]x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1[/tex]
So, The value of x when b is 3 is: x = -1

A travelers ground speed is 2 feet per second against the walkway and 8 feet per second with the walkway, what is the travelers speed off the walkway, what is the speed of yhe walkway
Answer:
The traveller's speed is 5ft/s and the walkway speed is 3ft/s
Step-by-step explanation:
Given
Represent the traveller's speed with T and the walkway's speed with W.
When the traveller walk against the walkway, we have:
[tex]T - W = 2[/tex] ---- i.e. 2ft/s against the walkway
When the traveller walk with the walkway, we have:
[tex]T + W = 8[/tex] ---- i.e. 8ft/s with the walkway
Required
Solve for W and T
[tex]T - W = 2[/tex] --- (i)
[tex]T + W = 8[/tex] --- (ii)
Add (i) and (ii)
[tex]T + T - W + W = 2 + 8[/tex]
[tex]T + T = 2 + 8[/tex]
[tex]2T = 10[/tex]
Divide both sides by 2
[tex]\frac{2T}{2} = \frac{10}{2}[/tex]
[tex]T = \frac{10}{2}[/tex]
[tex]T = 5[/tex]
Substitute 5 for T in (ii)
[tex]T + W = 8[/tex]
[tex]5 + W = 8[/tex]
Make W the subject
[tex]W = 8 - 5[/tex]
[tex]W = 3[/tex]
Hence, the traveller's speed is 5ft/s and the walkway speed is 3ft/s
Use SUBSTITUTION to solve the system
2x+y=-2
5x+3y=-4
Answer:
x=-2,y=2
Step-by-step explanation:
2x+y=-2 ----> y=-2-2x----(1)
25x+3y=-4 ---(2)
Replace (1) in (2)
5x+3(-2-2x)=-4
5x-6-6x=-4
-x=-4+6
-x=2
x=-2
If x=-2,then replace x in (1)
y=-2-2(-2)
y=-2+4=2
The point (0,5) is the midpoint between (-18, -10) and what other point?
Answer:
18,20
Step-by-step explanation:
Start aat the -10, go up to the 5, its 15, so if its 15 to one end go the other way and you get 20
Do the same with the - 18 and the 0
A craft club makes 95 identical paperweights to sell. They collect $230.85 from selling all of the paperweights. If the profit the club collects is two times as much as the cost to make each one, what does it cost the club to make each paperweight?
Answer: It costs $1.22 to make each paperweight.
Step-by-step explanation:
Given : Selling price of 95 identical paperweights = $230.85
Then, Selling price of 1 paperweight = (Selling price of 95 identical paperweights) ÷ 95
= $ (230.85 ÷ 95) = $ 2.43
Now, selling price of each paperweight = 2 x ( cost of each paperweight)
⇒ cost of each paperweight = (selling price of each paperweight ) ÷ 2
⇒ cost of each paperweight = $ 2.43 ÷ 2 = $ 1.215 ≈ $ 1.22
Hence, it costs $1.22 to make each paperweight.
If DF=70, find the value of x.
Answer:
x = 12
Step-by-step explanation:
DE + EF = DF
2x - 1 + 5x - 13 = 70
7x - 14 = 70
7x = 70 + 14
= 84
x = 84 ÷ 7
x = 12
Answer: x=12
Step-by-step explanation:
2x-1+5x-13=70
Combine like terms
7x-14=70
Add 14 to both sides
7x=84
Divide both sides by 7
X=12

Answer:

Step-by-step explanation:
If the measure of two sides of the triangle are 3 feet's and 7 feet's, which is the least possible whole number measure for the third side
Answer:
5 feet
Step-by-step explanation:
By triangle inequality, the sum of lengths of any two sides has to be strictly greater than the length of the third side.
Let x feet be the length of the third side.
We have 3+x>7, x+7>3 and 3+7>x.
Solving these, we get x > 4, x > -4 and x < 10.
The solution is therefore 4 < x < 10 and the smallest whole number which satisfies the inequality is 5.
Therefore the answer is 5 feet.
H varies directly to the cube of c.
When H = 40, C = 2.
Find the value of H when c=5
Answer:
H = 625
Step-by-step explanation:
Given H varies directly as c³ then the equation relating them is
H = kc³ ← k is the constant of variation
To find k use the condition when H = 40, c = 2, then
40 = k × 2³ = 8k ( divide both sides by 8 )
5 = k
H = 5c³ ← equation of variation
When c = 5, then
H = 5 × 5³ = 5 × 125 = 625

Plsssss help??? Also do any of u know a graphing app that shows u the points and were to put them?
Answer:
See below
Step-by-step explanation:
There are two ways to graph an equation.
1st Way:
We can use a graphing calculator. (See the attached file)
2nd Way:
We can take the values of x as 0, 1 , 2 (Or anything).
Then, We have to put the values of x in the equation to get the value of y accordingly.
According to these values, Plot the graph.
Also,
Slope = 5 / 6
y-intercept = 1

AB formed by (0-2) and (0,7)
CD formed by (3,-5) and (6,-5)
Answer:
AB is undefined, CD is y = -5
Step-by-step explanation:
Find both of the line's slopes. You can use the formula for slope to calculate this answer because you know two points on the line for both lines (Look below). If you plug in the points for AB, you would have ( -2 - 7)/0, which would be undefined, because anything divided by 0 is undefined. Since the slope for AB is undefined, it is undefined. Next, we have CD. If you plug in the points for CD, you would get (-5 - (-5))/(6 - 3), which would be 0/3, which is 0. This means that the slope is 0. Next, we have to plug in the points for CD into the formula for equation of the line (Look Below), which would be y - (-5) = 0 * (x - 6), which simplifies to y + 5 = 0, which is y = -5.
Formula for Slope:
[tex]\frac{y1 - y2}{x1 - x2}[/tex]
Usable with 2 points of the line given ((x1, y1) and (x2, y2))
Formula for Equation of the Line:
[tex]y - y1 = slope * (x - x1)[/tex]
Usable with the slope and a point given ((x1, y1))
Answer: AB is undefined (AB is not a relationship, slope is undefined (Vertical Line)) and CD is y = -5 (Horizontal Line)
Solve that and 10 points given

Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg, 1,5 kg de manzanas a 1,6 el kg y 1,5 kg de plátanos a 1,25 € el kg . Si juntamos toda la fruta en la misma bolsa , ¿cuál es su peso ? ¿ cuanto ha pagado Daniela por toda la fruta ?
Answer:
a) 5,5kg
b) 8,65 €
Step-by-step explanation:
Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg, 1,5 kg de manzanas a 1,6 el kg y 1,5 kg de plátanos a 1,25 € el kg.
a) Si ponemos toda la fruta en la misma bolsa, ¿cuál es su peso?
Naranjas = 2,5 kg
Manzanas = 1,5 kg
Plátanos = 1,5 kg
Por lo tanto:
El peso total
= Peso de las naranjas + Peso de las manzanas + Peso de las bananas
= 2,5 kg + 1,5 kg + 1,5 kg
= 5,5 kg
b) ¿Cuánto ha pagado Daniela por toda la fruta?
Costo de las naranjas
Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg
1 kg = 1,75 €
2,5 kg = x
x = 2,5 × 1,75 €
x = 4,375 €
Costo de las manzanas
1,5 kg de manzanas a 1,6 € el kg
1 kg = 1,6 €
1,5 kg = x
Cruz multiplicar
x = 1,5 × 1,6 €
x = 2,4 €
Costo de los plátanos
1,5 kg de plátanos a 1,25 € el kg.
1 kg = 1,25 €
1,5 kg = x
Cruz multiplicar
x = 1,5 × 1,25 €
x = 1.875 €
La cantidad que Daniela pagó por toda la fruta es:
4,375 € + 2,4 € + 1,875 €
= 8,65 €
