Find two numbers if their sum 16 and their ratio is 5:7
Answer:
6.666 or 6 2/3 and 9. 333 or 9 1/3
Step-by-step explanation:
5+7 = 12 so 1 part is 1
16/12 = 1.333.. = 1 1/3 1 part is changed when the total is higher
5 x 1 1/3 = 6.666 6 2/3
7 x 1 1/3 = 9. 333 = 9 1/3
Answer:
Step-by-step explanation:
Let A and B stand for the two numbers.
A + B = 16
A/B = 5/7
Rearrange the first and substitute:
A = 16-B
(16-B)/B = 5/7
(16-B) = 5B/7
5B/7 = (16-B)
5B = 7(16-B)
5B = 112 - 7B
12B = 112
B = 9.3333 or 9 1/3
A = (16 - 9.333) or (16 - 9 1/3)
A = 6.6667 or 6 2/3
A + B = 16?
9 1/3 + 6 2/3 = 16 YES
A/B = 5/7 ?
(6 2/3)/(9 1/3) = (20/3)/(28/3) = (20/3)*(3/28)
= (20/28) = 5/7 YES

a square has sides 7.4cm long.
work out the area of the square.
Area of a square = Side x side
Area = 7.4 x 7.4
Area = 54.76 cm^2
Answer:
Area of the square = (Side of the square)²
Area of the square = (7.4 cm)² = 54.76 cm²
54.76 cm² is the right answer.helpppp pleaseeeeeeeee

Is y=1/2x^3-4 Linear
Answer:
Yes, because x is rasied to the power of 3
Step-by-step explanation:
Linear algebra is the branch of mathematics concerning linear equations such as:
{\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}=b,}{\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}=b,}
linear maps such as:
{\displaystyle (x_{1},\ldots ,x_{n})\mapsto a_{1}x_{1}+\cdots +a_{n}x_{n},}{\displaystyle (x_{1},\ldots ,x_{n})\mapsto a_{1}x_{1}+\cdots +a_{n}x_{n},}
and their representations in vector spaces and through matrices.[1][2][3]
Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as lines, planes and rotations. Also, functional analysis, a branch of mathematical analysis, may be viewed as the application of linear algebra to spaces of functions.
Linear algebra is also used in most sciences and fields of engineering, because it allows modeling many natural phenomena, and computing efficiently with such models. For nonlinear systems, which cannot be modeled with linear algebra, it is often used for dealing with first-order approximations, using the fact that the differential of a multivariate function at a point is the linear map that best approximates the function near that point.
knits hats for her family and friends. In the first week, she knits 4 hats. The next week, she has some help, and together, they knit four times as many hats. The following week, she has even more help, and they knit four times as many hats as the week before. The fourth week, Jillian, her friends, and family, knit four times as many hats as the third week.How many hats will they knit in the fourth week
Answer:
[tex]first \: week - 4hats \\ second \: week - 4(4) \\ - 16hats \\ third \: week - 4(16) \\ - 64hats \\ fourth \: week - 4(64) \\ - 256hats \\ total = 4 + 16 + 64 + 256 \\ = 340hats[/tex]

Answer:
a) x = -9
b) p = (q - x)/3
Step-by-step explanation:
a) Substitute the values in to the equation
x = 3p + q
x = 3(-2) + -3
x = -6 + -3
x = -9
b) Make p the subject
x = 3p + q
(add 3p to both sides)
x + 3p = q
(subtract x on both sides)
3p = q - x
(divide on both sides)
p = (q - x)/3
Answer:
Given
x = 3p + qa)
p = -2, q = -3 ⇒ x = 3(-2) - 3 = -6 - 3 = -9b)
x = 3p + q3p = x - qp = (x - q)/3(-11, 12),(-4,-9) slope
Answer:
slope = -3

so like the answer to number three, -51 + -9 your answer is negative 60, number four your answer is 21, number seven your answer is 43, number 8 your answer is -34 number 11 your answer is 6 number 12 your answer is 12 hopefully you catch on
Answer:
Step-by-step explanation:
1. -51 + (-9) = -60
2. 27 + (-6) = 21
3. 1 + (-30) = -29
4. 15 + (-25) = -10
5. 50 + (-7) = 43
6. -19 + (-15) = -34
7. (-23) + 9 = -14
8. -19 + (-21) = -2
9. -17 + 11 = -6
10. 20 + (-8) = 12
11. (-15) + (-7) = -22
12. 12 + (-14) = -2

what is the length of segment AB?
Answer:
13
Step-by-step explanation:
12^2+5^2=169
sqrt 169 =13
Answer:
13
Step-by-step explanation:
Use Pythagorean Theorem ([tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]):
side a = 5
side b = 12
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
= [tex]5^{2}[/tex] + [tex]12^{2}[/tex] = 169
[tex]\sqrt{169}[/tex] = 13

Solving the systems of equations. Write a system of
equations and solve.
You sell tickets for admission to your school play and collect a
total of $156. Admission prices are $8 for adults and $4 for
children. you sold 24 tickets. How many adult tickets and how
many children tickets did you sell?
Adults tickets =
Children tickets =
Answer:
Adult tickets = 15
Children tickets = 9
Step-by-step explanation:
x = adult tickets
y = children tickets
8x + 4y = 156
x + y =24
Therefore,
x = 24 - y
y = 24 - x
Substitute,
8 (24 - y) + 4y = 156
192 - 8y + 4y = 156
-8y + 4y = 156 - 192
-4y = -36
y = 9
Therefore,
x + 9 = 24
x = 24 - 9
x = 15
Check your answers
8x + 4y = 156
8(15) + 4(9) = 156
120 + 36 = 156
156 = 156
