75 cm²
37.5 cm²
40.5 cm²
Answers
The total area of the sketch will be 40.5 cm².
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The sketch of this crayon represents an irregular polygon.
Dimension of the polygon are given in the figure,
To calculate the area of the given figure first we need to break this into two parts:
The first one will be rectangular form with a length of 12.5 cm and a width of 3 cm
The second one will be in triangular form with a height of 2 cm and a base of 3 cm.
Area of rectangle = length * width
in our case,
Area of rectangle = 12.5*3
Area of rectangle = 37.5 square cm
Area of triangle = 1/2 base *height
In our case,
Area of triangle = 1/2* 3 * 2
Area of triangle = 3 square cm
So,
The total area of the sketch = area of rectangle +area of the triangle
The total area of the sketch = 37.5 + 3
The total area of the sketch = 40.5 Square cm
Therefore, the total area of the sketch will be 40.5 cm².

This car dealership pays the salesperson a bonus for selling the car equal to 6.5% of the sale price. How much commission did the salesperson lose when they decided to offer a 10% discount on the price of the car? Show your work.
Answers
Answer: 1%
Step-by-step explanation:
Let x be the sale price.
Commission = 6.5% of x = 0.065x (Before discount)
Discount amount = 10% of x = 0.1x
Final sales price = x- 0.1x = 0.9x
Commission after discount = 6.5% of (0.9x)
= 0.065 (0.9x)
= 0.0585x
Loss = ( Commission before discount ) - (Commission after discount )
= 0.065x - 0.0585x
= 0.0065x
Loss percent = [tex]\dfrac{0.0065}{0.65}\times100=1\%[/tex]
Hence, the salesperson lose 1% when they decided to offer a 10% discount on the price of the car.
The sales person lost a commission of 10%.
Let's assume that the price of the car is 1000. The commission the salesperson earns is $65(0.065 x 1000). The price of the car after the 10% discount is $900 (0.9 x 1000). The commission the salesperson earns on the discounted car is $58.5(0.065 x $900). The commission lost = (58.5 / 65) - 1 = 10%To learn more about how to calculate discounts, please check: https://brainly.com/question/9350849

3. Ivan has completed 45% of his walk.
He has already walked 9 km. How much farther does he have left to walk?
Answers
Answer:
11
Step-by-step explanation:
The required distance left to the walk will be 11 km.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Let the total distance of the walk would be x km
As per the given information, the required solution would be as:
⇒ 45% of x = 9
45% is expressed as 45/100 in fractional form
⇒ (45/100)x = 9
45/100 is expressed as 0.45 in decimal form
⇒ 0.45x = 9
⇒ x = 9/0.45
⇒ x = 20
So the total distance of the walk is 20 km
Since he has already walked 9 km.
So, he has left to the distance of the walk = 20 - 9 = 11 km
Therefore, the required distance left to the walk will be 11 km.

The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4⟩.
Answers
Answer:
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)
Step-by-step explanation:
We are given that the vertices of quadrilateral MNPQ are M(-3,-2),N(-1,4),P(2,4) and Q(4,-2).
We have to translate the quadrilateral MNPQ using vector <3,-4>
The translate the coordinates of vertices (x,y) using the vector <a,b> is given by the rule
[tex](x,y)\rightarrow (x+a,y+b)[/tex]
Using the rule
The new coordinates of M
[tex](-3,-2)\rightarrow (-3+3,-4-2)[/tex]
[tex](-3,-2)\rightarrow (0,-6)[/tex]
The new coordinates of N
[tex](-1,4)\rightarrow (2,0)[/tex]
The new coordinates of P
[tex](2,4)\rightarrow (5,0)[/tex]
The new coordinates of Q
[tex](4,-2)\rightarrow (7,-6)[/tex]
Hence, after translation the new vertices of quadrilateral are
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)

Here are the ingredients to make 12 cupcakes.

Mark is making cupcakes to sell at his school play.
Mark wants to make 1 cupcake for each adult and 2 cupcakes for each child.
There will be 152 adults and 80 children at the school play.
Mark can get these ingredients from the school kitchen.
5 kg butter
5 kg caster sugar
90 eggs
5 kg flour
Make a shopping list of any ingredients Mark still needs, showing the amount of each
ingredient.
Answers
Answer:
Mark needs 2 kg butter, 2 kg caster sugar, 14 eggs, and 1.5 kg flour.
Step-by-step explanation:
Alright, first you double the number of kids, as Mark wants each kid to have two cupcakes, not one. (Then add 80+80 to get 160)
Now add the adults to children: 160+152=312
now divide by 12 to see how many batches of cupcakes he needs to make.
312÷12=26 So he needs to make 26 batches
Now here are the ingredients needed to make 12 batches of cupcakes (I multiplied the amount of each ingredient by 26)
5200 g (5.2 kg) butter, 5200 g (5.2 kg) caster sugar, 104 eggs, and 6500 g (6.5 kg) flour.
now make the measurements the same as Mark's ingredients (or the other way around)
(to save time I am not showing each one, just the normal ingredients turned into kg and compared)
5 kg butter < 5.2 kg butter
5 kg caster sugar < 5.2 kg butter
90 eggs < 104 eggs
5 kg flour < 6.5 kg flour
Now do a little subtraction.....
5.2 kg-5 kg = 2 kg butter is needed....
5.2 kg - 5 kg = 2 kg caster sugar is needed....
104 - 90 = 14 eggs needed....
6.5 kg - 5 kg = 1.5 kg flour needed....
And there you go!!! Hope this helped!!! :D

What is m∠DEF?
Enter your answer in the box.
There is a triangle DEF in which side DE is congruent to side EF and G is the midpoint of the side DF. Segment EG intersect the side DF at point G. The measure of angle DEG is (3y+4) degrees and the measure of angle FEG is (5y-10) degrees.
Answers
Answer:
m<DEF = 8y - 6
Step-by-step explanation:
Given that: DEG = [tex](3y +4)^{o}[/tex], and FEG = [tex](5y-10)^{o}[/tex].
The given triangle is an isosceles triangle with sides DE ≅ DF.
But,
m<DEF = DEG + FEG
= [tex](3y +4)^{o}[/tex] + [tex](5y-10)^{o}[/tex]
= 3y + 4 + 5y - 10
= 8y - 6
m<DEF = 8y - 6
Therefore, the measure of < DEF is 8y - 6.
