Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because 60 - 5 = 12. Complete the

If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?
Answers
Answer:
3t = 60
Step-by-step explanation:
2(3t - 10) = 40 + 3t
6t - 20 = 40 + 3t
3t - 20 = 40
3t = 60
If you need to simplify that then the answer would be t = 20.

Answer:
[tex]x=7[/tex]The length of MN = 13The length of NO = 13The length of OM = 13Step-by-step explanation:
As the given triangle is equilateral as all the sides of the triangle are equal.
[tex]MN = 3x-8[/tex]
[tex]NO=2x-1[/tex]
[tex]OM=5x-22[/tex]
As all the sides are equal, i.e.
[tex]MN=NO=OM[/tex]
as
[tex]MN=NO[/tex]
[tex]3x-8=2x-1[/tex]
Add 8 to both sides
[tex]3x-8+8=2x-1+8[/tex]
[tex]3x=2x+7[/tex]
[tex]x=7[/tex]
Hence, the value of x = 7
so putting the value of x to determine the lengths of the
segments MN, NO, and MO
[tex]MN = 3x - 8[/tex]
[tex]= 3(7)-8[/tex]
[tex]=21-8[/tex]
[tex]=13[/tex]
Hence, the length of MN = 13
[tex]NO = 2x-1[/tex]
[tex]=2(7)-1[/tex]
[tex]=14-1[/tex]
[tex]=13[/tex]
Hence, the length of NO = 13
[tex]OM = 5x-22[/tex]
[tex]= 5(7)-22[/tex]
[tex]= 35-22[/tex]
[tex]=13[/tex]
Hence, the length of OM = 13

A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line. Assuming that field goal attempts can be considered random events, what is the probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line?
Answers
Answer:
Step-by-step explanation:
answer should be 0.39
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is 0.39.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line.
Assuming that field goal attempts can be considered random events.
P = 0.85
n = 5
Standard deviation = √{5 x 0.85 x (1 - 0.85) = 0.79
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is,
= P (X ≥ 4)
= P (X ≥ 3.5)
= 1 - P(X < 3.5)
= 0.39
Therefore, the probability is 0.39.

Answer:
F, T, T, T, T, F
Step-by-step explanation:
PM and PN are "midlines" of the triangle JKL. As such, they are parallel to and half the length of the side of ΔJKL they don't intersect. The relationships of angles and transversals of parallel lines apply. LMPN is a parallelogram, so opposite sides are the same length.
a) JL is not 36, it it twice that. (F)
b) ML is the same length as PN, 36. (T)
c) MP is half of LK, so is 97/2 = 48.5. (T)
d) ∠JLK corresponds to ∠JMP, so is congruent. (T)
e) ∠PNK corresponds to ∠JLK, so is congruent. (T)
f) MP intersects PK at point P, so cannot be parallel. (F)
write 28 + 24 as a product of two factors using the GCF and the distributive property
Answers
Answer:
4 x 13
Step-by-step explanation:
GCD of 28 and 24 is 4
28 = 4 x 7
24 = 4 x 6
u take the 4 out
4 (7 + 6)
4 x 13
The product of two factors using the GCF and the distributive property is 4(13).
What is the meaning of the greatest common divisor/factor?
The largest integer of highest degree that is an exact divisor of each of two or more integers.
The greatest common divisor of 24 and 28
24=2×2×2×3
28=2×2×7
We can see that the 2 and 2 is common in 24 and 28
The GCD of 28 and 24 is=2×2= 4
For the distributive property we have
28 = 4 x 7
24 = 4 x 6
we take the 4 out
4 (7 + 6)
=4 x 13
Therefore the GCD is 4 and by distributive property product is 4(13).

What is an equation?Equation is a mathematical and physical statement that describes physical occurrences and the relationship between various physical quantities. It usually consists of basic variables that show physical quantities, but it may also point to a personal variable like your energy.
An equation that has a "equal to sign (=)" either reveals the answer or represents the value of the variable. However, since there is no equal sign in the case of an expression, there can be no clear answer and the value of the concerned variable cannot be displayed.

Given f(x) = 2x^3 + ax^2 - 7a^2x - 6a^3, determine whether or not x-a and x+a are factors of f(x). Hence, find, in terms of a, the roots of f(x) = 0.
thankyou so much
Answers
Answer:
Step-by-step explanation:
f(x) = 2x³ + ax² - 7a²x - 6a³
= 2x³ - 2a²x + ax² - a³ - 5a²x - 5a³
= 2x(x² - a²) + a(x² - a²) - 5a²(x+a)
= (2x+a)(x - a)(x + a) - 5a²(x + a)
= (x + a)[(2x + a)(x - a) - 5a²]
= (x + a)(2x² - ax - 6a²)
= (x + a)(2x + 3a)(x - 2a)
x-a is the factor of the equation and x + a is not a factor of the equation,
All the roots of the equation are x + a, 2x+3a, x-2a.
What is a cubic equation ?"In algebra, a cubic equation in one variable is an equation of the form

The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd-degree polynomial functions). "
Given equation is [tex]f(x) = 2x^3 + ax^2 - 7a^2x - 6a^3[/tex]
Now,
[tex]f(x) = 2x^3 + ax^2 - 7a^2x - 6a^3\\\\= 2x^3 - 2a^2x + ax^2 - a^3 - 5a^2x - 5a^3\\\\= 2x(x^2 - a^2) + a(x^2 - a^2) - 5a^2(x+a)\\\\= (2x+a)(x - a)(x + a) - 5a^2(x + a)\\\\= (x + a)[(2x + a)(x - a) - 5a^2]\\\\= (x + a)(2x^2 - ax - 6a^2)\\\\= (x + a)(2x + 3a)(x - 2a)[/tex]
Hence, the roots of the equation are x + a, 2x +3a, x - 2a.

Students are making ornaments and each takes 1/4 of a piece of Bristol board. They go to the cupboard and find 2 1/2 pieces of Bristol board. How many ornaments can they make?
Answers
Answer: 10 ornaments
Step-by-step explanation:
From the question, we are informed that students are making ornaments and each takes 1/4 of a piece of Bristol board. We are further told that they go to the cupboard and find 2 1/2 pieces of Bristol board.
The number of ornaments that they make will be gotten by dividing 2 1/2 by 1/4. This will be:
= 2 1/2 ÷ 1/4
= 5/2 ÷ 1/4
= 5/2 × 4/1
= 10

There are two gardens, garden A and garden B are shown in the image below.
Is there more than one expression that can be used to represent the perimeter of each garden?
Answers
Step-by-step explanation:
garden a:
perimeter=2xlength+2xwidth = 2x(5x(2x-3))+2x(2x-3) = 20x-30 + 4x-6 = 24x-36 / 12(2x-3) feet
garden b:
perimeter= 5x+5 + 4x+2 + 8x-8 = 17x - 1 feet
Answer:
Perimeter A = 24x - 36Perimeter B = 17x - 1Step-by-step explanation:
garden A
Width (W) = 2x - 3
Length (L) = 5(W)
= 5 (2x - 3)
= 10x - 15
Perimeter A = 2L + 2W (perimeter of a rectangular garden)
= 2(10x - 15) + 2(2x - 3)
= 20x - 30 + 4x - 6
= 24x - 36
garden B
side 1 = 5x + 5
side 2 = 4x + 2
side 3 = 8x - 8
Perimeter B = sides (1 + 2 + 3)
= 5x+5 + 4x+2 + 8x-8
= 5x + 4x + 8x + 5 + 2 - 8
= 17x - 1
