The equations m = 2d and m+d = 120 represent this situation.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.
The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero.
d = kilograms of dark chocolate
m =kilograms of milk chocolate
So, her recipe calls for twice the amount of dark chocolate as milk chocolate.
Mathematically speaking:
m = 2d
She needs to buy 120 kg, of chocolate in total. So;
m + d = 120
The following system of equations represents the situation:
m = 2d
m+d = 120

Answer:
answer is 9
Step-by-step explanation:
1st method: Proportion
15/100 = n/60
cross-multiply to get:
100n = 900
n = 900/100
n = 9
2nd method: Convert % to Decimal and Multiply
.15 × 60 = 9
A scale drawing of a dance floor is shown. What is the area of the actual dance floor? 22 cmon the top and bottom and 14 cm on the sides 5 cm equals 8 feet
Answer:
The area of the dance floor will be 788.48ft²
Step-by-step explanation:
Since 5cm represents 8ft, it means
1cm represents 8/5ft.
The scale length is 22cm, therefore the actual length would be
22 x 8/5ft = 35.2ft
The scale breadth is 14cm, therefore the actual breadth would be
14 x 8/5ft = 22.4ft
The area of the dance floor will be
(35.2ft)(22.4ft) = 788.48ft²

Steve reaches into a bag with 5 marbles 3 yellow marbles and 2 green marbles and randomly selects one the he puts the marble back and sam reaches into the same bag and randomly selects a marble is this independent or dependent
Answer:
Independent
Step-by-step explanation:
The reliance of an event on the outcine of another event gives rise to a dependent event. For any two or more event, whereby the outcome of event A has no effect on the possible outcome of event B, then such scenario is termed as being Independent. In the scenario described above, the outcome oof Sam's pick does not depend on the outcine of Steve's pick. This is because, once Steve makes his selection, the marble is returned into the box before Sam makes his own selection.Therefore, no matter the color of marble picked by Steven, it will have no bearing on the outcome of Sam's pick.
1. Point D (9,-8)
is
reflected to D' (9.8).
X axis or y axis
Answer:
X-Axis
Step-by-step explanation:
The Y changed from negative to positive meaning that it reflected across the X-Axis
(っ◔◡◔)っ ♥ Hope It Helps ♥
Answer:
x axis
Step-by-step explanation:
Since the x value stayed the same and the y value changed, we can tell that the point was reflected over the x axis.
Another way to think of it:
If you draw a graph and put both points on the graph, try to fold the paper on one of the axis's. Whichever fold causes the two points to touch, is the axis that point D was reflected on.

What is the following product
Answer:
1.) y3
Step-by-step explanation:
Sketch the graph of the following equations: y=x+5, y=-(x+5), and y = |x+5|
The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equations are,
y = x + 5
y = - (x + 5)
y = |x + 5|
Since, All equations shows equation of line.
Hence, We can draw all the equations as shown in figure.
y = x + 5
Slope = 1
y - intercept = 5
y = - x - 5
Slope = - 1
y - intercept = - 5
Thus, The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.

COMPOSITE FIGURES!!! can you please help
It wants me to find m∠2 from this
Answer:
Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°
Step-by-step explanation:
Answer:
90°
Step-by-step explanation:
This is a kite.
The angle measures of the diagonals (the lines in the middle) are always going to be 90° if they looks like this without any other measures. This goes for all other quadrilaterals as well.
m∠2=90°

Find the measure of the sixth interior angle of a hexagon if the measure
of the other five interior angles are 80°, 90°, 130°, 130°, and 150°. (Show
all work)
Answer:
140°
Step-by-step explanation:
The sum of interior angles of a n-agon is (n - 2) * 180°
a hexagon should have the sum of angles equal to
4 * 180° = 720°
Now we know that the other five angles have total measure
80° + 90° + 130° + 130° + 150° = 580°
So the sixth one has to be:
720° - 580° = 140°
Answer:140°
Step-by-step explanation: required equation : 180*(n-2)
since it is a hexagon, the sum of all interior angles=180*(6-2)
=180*4 =720°
now the measure of 6th angle=720 -(80+90+130+130+150)
= 720 -580
= 140

Priscilla received 240 votes in the election for student council president. That was 60% of the students who voted in the election. How many students voted in the election? *
Answer:
400 students voted in the election
Step-by-step explanation:
Given:
Total number of votes received by Priscilla = 240
This was 60% of the students who voted in the election.
To find: Total number of students who voted in the election
Solution:
Total number of votes received by Priscilla = 60% of Total number of students who voted in the election
240 = 60% of Total number of students who voted in the election
240 = [tex]\frac{60}{100}[/tex] × Total number of students who voted in the election
So,
Total number of students who voted in the election [tex]=\frac{240(100)}{60}=400[/tex]

Answer:
All sides are equal better explenation bellow
Step-by-step explanation:
It's a mirror flip of a ABC triangle
Yet you can say AB Is = to DE
And since most likely it's a 60° triangle all the angles are 60°
All triangles have 180°
Which means AB =BC
BC= AC
BC =CD
DE= CD
CE=DE
Which means all the sides are equal
