We can calculate the score as:
A) What is the maximum score you could get on the quiz?
Maximum score one can get on the quiz if he / she correct all i.e. -
25 × 3 = 75.
B) What is the minimum score you could get on the quiz?
Minimum score one can get on the quiz if he / she correct all i.e. -
25 ×-2 = -50.
C) A student answers 15 questions.10 are correct. How many points does he score?
Scored points = (10 × 3) + (5 × -2)
= 30 -10
=20 points
D) Another student answers 21 questions. 6 are correct. How many points does she score?
= 6 × 3 + (15 × -2)
= 18-30
= - 12 points
Hence, the answer are a- 75 , b- -50 , c - 20, d- -12.

Jamie invests money. In the first year it increases to 110% of its original value.
He spends 20% of the profit on a cricket bat and 1/8 of the reminder on a cricket jumper.
He is left with £140 profit. How much did Jamie invest?
Answer:
£2000
Step-by-step explanation:
Let the money invested be x.
After 1 year, the money is now 110% of x = 1.1x
Original amount of money: x
Profit in 1 year: 0.1x
He spends 20% of the profit on a cricket bat.
0.2 * 0.1x = 0.02x spent on cricket bat
The reminder of the profit is 0.8 * 0.1x = 0.08x
He spends 1/8 * 0.08x on a cricket jumper.
Amount of profit he has:
0.1x - 0.02x - 0.125 * 0.08x
This equals £140
0.1x - 0.02x - 0.125 * 0.08x = 140
0.08x - 0.01x = 140
0.07x = 140
x = 140/0.07
x = 2000
Answer: £2000

The cost of a new car is $16,500. You can Finance the purchase by paying $500 down, and $350 a month for 60 months. What is the amount financed (Cash Price - Down Payment)?
Answer:
the amount financed is $16,000
Step-by-step explanation:
The computation of the amount financed is shown below:
As we know that
Amount financed = cash price - down payment
= $16,500 - $500
= $16,000
Hence, the amount financed is $16,000
If we deduct the down payment from the cash price so we can get the amount financed

Answer:
B. a square must have 4 right angles, but a rhombus may or not have 4 right angles.
Answer:
B
Step-by-step explanation:
The main difference between a square and a rhombus is a square must have 4 right angles, but a rhombus may or may not have 4 right angles. All the angles of a square have to be 90 degrees. All right angles are 90 degrees. All squares are rhombuses, but not all rhombuses are squares. There are occasions when a rhombus has 4 right angles.

Answer:
202m
Step-by-step explanation:
Use pythagoream theorum to find the hypotenuse. So [tex]a^{2} +b^{2} =c^{2}[/tex], where the height (40m)=a and the anchor length (198m)=b. That leaves us with [tex]40^{2} +198^{2} =c^{2}[/tex], doing the math out for that we get 40,804=[tex]c^{2}[/tex], taking the square root of 40,804 we get our answer of 202m

dimensions of the box, without tilting any cubes in any directions,
then choice B) can be justified. This leaves spaces (some volume) in the box
not filled by the cubes.
How many whole number of edges of the cubes fit into 4 cm?
4 / 3 √ 2 must be rounded down to 3.
How many whole number of edges of the cubes fit into 8 cm?

The required measures of the circle are:

m∠CBE = 45, mDAC = 225. m∠ABE=135
m∠ABF=120
What are the sections of the circle?A section of a circle is a region enclosed by a chord and an arc of the circle. It is also called a circular sector. A circular sector is defined by its central angle, which is the angle between the two radii that form the sector, and its radius, which is the distance from the center of the circle to the endpoints of the sector.
Here,
A circle is shown,
mDF = 75 [shown in the image]
m∠FBE = 60 + ∠CBE
m∠FBE = 60 + ∠ABD [∠ABD=∠CBE]
m∠FBE = 60 + 45 [∠ABD = 180 - 75-60]
m∠FBE = 105,
Similarly,
mFC=60, m∠CBE = 45, mDAC = 225, m∠ABE=135, and m∠ABF=120

A triangle has an area of 32 square centimeters and a height of 1 centimeters. What is the length of the base of the triangle?
A.64 cm
B.32 cm
C.16 cm
D.8 cm
If you answer I will mark you Brainliest!
Answer:
divide the figure into two parts.
area of triangle = 1/2×base×height
area of triangle = 1/2×3×3
area pf triangle = 4.5 units²
area of square = side²
area of square = 3²
area of square = 9unit²
Answer:
The figure is made up of a square and a triangle.
We will find both of their areas separately and then combining them will give us the required area.
Area of the triangle : ½ × base × height
= ½ × 3 × 3
= ½ × 9
= 4.5 units²
Area of the square : (side)²
= 3²
= 9 units²
Now, required area = (4.5 + 9) units²
= 13.5 units²
The volume of a cone is given by v=13πr2h. If a cone has volume 3π, what is the height of the cone when the radius is 12?
Answer:
16units
Step-by-step explanation:
Given data
The expression for the volume of a cone is given as
v=1/3πr^2h
v= 3π
r= 12
h=???
Substitute
3π= 1/3*π*12^2*h
3= 1/3*144*h
3= 144h/3
cross multiply
3*3= 144h
9= 144h
h= 144/9
h=16 units
Hence the heeight is 16units
