Answer:
pretty sure its 18*5
Step-by-step explanation:
1. Solve 3^2 (three squared)
3 x 3= 9
2. Replace 3^2 with 9
it should now look like this:
2*9*5
3. Multiply left to right
2*9= 18
18*5

Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Step-by-step explanation:
Step 1: Define
Point (5, 1)
Point (9, -6)
Step 2: Identify
x₁ = 5, x₂ = 9
y₁ = 1, y₂ = -6
Step 3: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
Substitute in points [DF]: [tex]\displaystyle d = \sqrt{(5-9)^2+(1+6)^2}[/tex]Here,
two points are (5,1) and (9,-6)
So,
x1=5
x2=9
y1=1
y2= -6
we know that,
Distance formula:- [tex]\bold{D=\sqrt{(x_2 - x_1 )^2+(y_2 - y_1)^2} }[/tex]
According to the question,
Distance between (5,1) and (9,-6)
[tex]\bold{D=\sqrt{(5-9)^2+(1-\{-6\})^2} }[/tex]
[tex]\bold{D=\sqrt{(5-9 )^2+(1+6)^2} }[/tex]
so,
option C is correct..

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.

Now draw a vertical line (solid) through x = -7.
Finally, shade the area including and to the right of x = -7.
If b = 110 what is the value of g
IM BEING TIME PLZ HELP THANK YOU
Answer:
its 120 degrees
Step-by-step explanation:
add up all the know angles (110.60,70) then take that number and subtract it from 360, (360 is the number you get if you add all sides four sided shape)
The measure of the value of g is, 60° by definition of alternate angles of parallel lines.
What are Parallel lines?Parallel lines are those lines that are equidistance from each other and never intersect each other. and, Parallel lines are lines in a plane that are always the same distance apart and never intersect. But Perpendicular lines are lines that intersect at a right (90 degrees) angle.
We have to given that;
Two parallel lines are shown in image.
And, The measure of b = 110°
Here,
By the figure, we have;
A transverse line cut the parallel lines.
And, Both angles 60 and g are alternate angles of parallel lines.
We know that;
The alternate angles of parallel lines are equal to each other.
Hence, The value of measure of g = 60°
So, We get by the definition of alternate angles of parallel lines,
⇒ The measure of g = 60°

Answer:
because they have 3 sides
Step-by-step explanation:
I need help.
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

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

Answer:
A
Step-by-step explanation:
You can make an infinite number of triangles with those three angle measures, because the side lengths can be different.
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.

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 €

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

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
the measure of one angle of the angles in a linear is 30 less than one-half the measure of the other angle. Find the measure of each angle.
Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is [tex]\frac{1}{2}[/tex] x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + [tex]\frac{1}{2}[/tex] x - 30 = 180, that is
[tex]\frac{3}{2}[/tex] x - 30 = 180 ( add 30 to both sides )
[tex]\frac{3}{2}[/tex] x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and [tex]\frac{1}{2}[/tex] x - 30 = [tex]\frac{1}{2}[/tex] (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
