The number of points Jaden scored in a game is less than 45, and is also a multiple of 7. How many points could Jaden have scored
Answer:
35
Step-by-step explanation:
The first few multiples of 7 are:
× 7 = 7
× 7 = 14
× 7 = 21
× 7 = 28
× 7 = 35
× 7 = 42
× 7 = 49
× 7 = 56
× 7 = 63
× 7 = 70
The number of points Jaden scored in a game less than 45, and a multiple of 7 is 35 points
How to find how many points Jaden scored?The multiples of 7 are;
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105......
Recall,
The number of points Jaden scored in a game is less than 45
From the options, we are left with 17 and 3517 is not a multiple of 7Therefore, the number of points Jaden scored in a game less than 45, and a multiple of 7 is 35 points

Classify this triangle by its sides and angles.
Answer:
choice 3) acute and equilateral
Step-by-step explanation:
I NEED HELP WITH THIS MATH
Answer:
v = 120
Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360
v = 360/3
v = 120
Answer:
89 = v

Greg has two coupons for a bicycle.
Coupon A: $19 rebate on a $81 bicycle
Coupon B: 20% off of a $81 bicycle
Choose the coupon that gives the lower price.
The price of Coupon A will be less than the price of Coupon B. Coupon A gives the lower price.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Greg has two coupons for a bicycle.
Coupon A: $19 rebate on an $81 bicycle. Then the price of a bicycle will be
⇒ $81 - $19
⇒ $62
Coupon B: 20% off of an $81 bicycle. Then the price of a bicycle will be
⇒ $81 x 0.80
⇒ $64.8
The price of Coupon A will be less than the price of Coupon B. Coupon A gives the lower price.

Answer:
Step-by-step explanation:
Q9) Surface Area of a cylinder
= 2πr(r + h)
Diameter = 12cm , Radius = Diameter/2 = 12 cm/2
r = radius = 6cm
h = height = 10 cm
Surface area = 2 × π × 6(6 + 10)
= 603.18579 cm²
Approximately = 603.2 cm²
Q11) Volume of a rectangular prism
Length × Width × Height
Length = 6.5cm
Width = 8.5 cm
Height = 4 cm
Volume = 6.5 cm × 8.5 cm × 4 cm
Volume = 221 cm³
Q12) Volume of the cylinder = πr²h
r = radius = 1.7m
h = height = 9 m
Volume = π × 1.7 × 9
= 81.71 m³
Approximately = 81.7 m³
Q13) Volume of the cylinder = πr²h
Diameter = 0.8m, Radius = Diameter/2 = 0.8m/2
r = radius = 0.4m
h = height = 1.5 m
Volume = π × 0.4 × 1.5
= 0.75 m²
Approximately = 0.8 m³

someone please helppp
Answer:
7
Step-by-step explanation:
We know that alternate angles ( Z angles) are equal
So, the angle that is adjacent to (13x + 2) = (12x+3)
First, calculate the measure of the angle adjacent to (13x+2)
We know that the angles on a straight line add up to 180 degrees.
Therefore, the angle adjacent to (13x+2) = 180-(13x+2)
Simplify this to: 178-13x
So, now we have an equation
178 - 13x = 12x + 3
Rearrange to find the value of x
25x = 175
x = 7
Hope this helps.
See image for question and answer choices
Answer:
B.
Step-by-step explanation:
So, lets remember a few things first.
#1: The formula for finding the answer is A^2+B^2=C^2
#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.
Now lets plug in what we already know, and see if we canf igure out the annswer:
A^2+12^2=13^2
Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.
If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:
Ok, not too bad, the A is the unkown value, which is the opposite side.
Now, how do we figure this out? Well, we just need to sovle for A.
To do this, lets clean up our equation by first sqauring all the values(except for the unkown):
A^2+144=169
Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.
This will now look like:
A^2=25(169-144=25)
Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.
([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])
A=5
This is your answer.

Find the perimeter of each shape
Equation :
X:
Perimeter:
Answer:
The equation is;
4(2.5x-3) = 3(2x-2)
The value of x is 1.5
Step-by-step explanation:
Mathematically, the perimeter of a square is simply the product of the length of the side and 4
Secondly, the perimeter of an equilateral lateral triangle is the product of the length of its side and 3
Thus, mathematically, we have it that;
4(2.5x-3) = 3(2x-2)
10x - 12 = 6x -6
10x -6x = -6 + 12
4x = 6
x = 6/4
x = 1.5
