Step-by-step explanation:
14 times ab is 14ab and 14 times 3a is 42a
In one round of a television game show, five questions are asked. The second question is worth twice as much as the first. The third question is worth three times as much as the second. The fourth question is worth four times as much as the third. The fifth question is worth five times as much as the fourth. If the fifth question is worth $12,000, what is the first question worth?
Answer:
$100
Step-by-step explanation:
1st q. 2nd q. 3rd q. 4th q. 5th q
x. 2x. 3(2x)=6x. 4(6x)=24x. 5(24x)=120x
100. 200. 600. 2400. 12000
since the 5th q was worth 12000 we know:
120x = 12000
x = 100
The symbol _____________ means "is similar to" and the symbol ____________ is the abbreviation for the word angle.
Answer:The symbol \sim∼ means "is similar to" and the symbol \angle∠ is the abbreviation for the word
angle.
Step-by-step explanation: i hope it is right i am sure it is
The symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." while "∠" represents the concept of an angle.
The symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." often used in mathematical equations or geometric diagrams to indicate the presence of a similarity.
On the other hand, the symbol "∠" is the abbreviation for the word "angle." In geometry, an angle is formed when two rays or line segments share a common endpoint.
Thus, the symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." while "∠" represents the concept of an angle.

(3x + 12)
(11x)
This is geometry could plz help me
Answer:
x = 12°
Step-by-step explanation:
3x + 12° + 11x = 180° {being co-interior angles }
12° + 14x = 180°
14x = 180° - 12°
14x = 168°
x = 168° / 14
x = 12°
Answer:
12
Step-by-step explanation:
( 3x + 12 ) + 11x = 180°
14x = 180 - 12
14x = 168
x = 168÷14
x = 12

graph BCD with b(0,6), C(2,-5), D(-8,-1), then order the angle measures from least to greatest
9514 1404 393
Answer:
C, B, D
Step-by-step explanation:
We can estimate the relative lengths of the segments using the difference of their coordinates:
BC = (2-0, -5-6) = (2, -11)
CD = (-8-2, -1-(-5)) = (-10, 4)
DB = (0-(-8), 6-(-1)) = (8, 7)
Then the lengths of the segments will be ...
BC = √(2^2 +11^2) = √125
CD = √(10^2 +4^2) = √116
DB = √(8^2 +7^2) = √113
DB is the shortest segment, so opposite the smallest angle, C.
The next-shortest segment is CD, opposite angle B.
The longest segment is BC, opposite angle D.
In order from least measure to greatest, the angles are C, B, D.

Can someone please tell me how to expand and simplify 4(x+1)^2?
[ i know now to expand brackets like (x+2)^2, but the 4 confuses me]
Expand the binomial first, then distribute the 4:
4 (x + 1)² = 4 (x ² + 2x + 1)
… = 4•x ² + 4•2x + 4•1
… = 4x ² + 8x + 4
Write down all the two-digit numbers that can be made using the digits 1,5 and 7.
Each digit can be repeated.
(3 marks)
Answer:
1,2,5,7,8 and 9. Thus, we have 6 numbers. Then we want to form two-digit numbers without repetition. There are 6 number that is possible to occupy first digit, right? 1,2,5,7,8 or 9. Because it’s without repetition, so the number that have been filled the first digit cannot be the second digit. Thus, the numbers that is possible to occupy second are 5 digits. Thus, there are 6 x 5 = 30 numbers that can we form from those 6 numbers: 1,2,5,7,8 and 9 without repetition.
or by using permutation, there are two place would be filled by six number, so the permutation is 6P2 = 6!/ (6–2)! = 6!/4! = 6 x 5 = 30.

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)
Answer:
4,3cm
Step-by-step explanation:
Passo 1
Um losango tem 2 diagonais, cujos comprimentos não são iguais
Temos que encontrar o comprimento da segunda diagonal
A fórmula é dada como:
Área de um losango = 1/2 (d1 × d2)
Área do losango = 12 cm²
d1 = Comprimento da primeira diagonal = 8cm
d2 = Comprimento da segunda diagonal = x
12 = 1/2 (8 × x)
12 = 1/2 (8x)
12 = 4x
x = 12/4
x = 3cm
O comprimento da segunda diagonal = 3 cm
Passo 2
A fórmula do comprimento da lateral de um losango é dada como:
s = √d1² + d2² / 2
d1 = 8cm
d2 = 3 cm
s = √8² + 3² / 2
s = √64 + 9/2
s = √73 / 2
s = 8,5440037453 / 2
s = 4,2720018727 cm
Aproximadamente = 4,3 cm

plz answer only if u know ur correct
Answer:
blue, y=150x
Step-by-step explanation:
x increased by 2 and y increased by 300 so y=150x
Answer:
Y=150x, blue, diamond, yeah
Step-by-step explanation:
On the orange line, x is increased by 2 and y is increased by 300. In this case, y = 150 times x. So y=150x. I hope this helped and I'm not really sure how else to explain it.
find the area of quadrilateral which all side is 4 cm and diagonal one is 7 and diagonal two is 6
Step-by-step explanation:
Your answer...... 21 cm^2
WANT MORE THEN FOLLOW ME, LIKE & MARK MY ANSWER AS BRAINLIST ANSWER
Answer:
the quadrilateral is a rhombus as its all four sides are equal (of 4cm) each
Area of rhombus = 1/2 (digonal 1 × digonal 2)
= 1/2 ( 7×6 )
= 1/2 ( 42)
= 21
hence area of quadrilateral is 21 cm square

The width of a rectangular rectangular prism is 30 cm. This is
12 more than one-fourth of the length. Find the
volume of the prism, given the height is 20 cm.
16. Equation:
17. Volume:
Answer:
16. 30 * (30+12)/4*(L)*20
17. Volume = 6300 * Length of rectangular prism
Step-by-step explanation:
The width of a rectangular prism is 30 cm. This is 12 more than one-fourth of the length. Find the volume of the prism, given the height is 20 cm.
Let L = length of rectangular prisim W = width and H = height
16.
Volume of a rectangular prism is width * length * height
30 * (30+12)/4*(L)*20
17.
= 30 * (30+12)1/4(L)*20
= 30 * (42/4)*L * 20
= 600 * 10.5 * L
= 6300 * L
Volume = 6300 * Length of rectangular prism
Here is an expression: 3⋅2 Evaluate the expression when is 1. Evaluate the expression when is 4.
Answer:
1.) 5
2.) 14
Step-by-step explanation:
As given,
the expression - 3x + 2
1.)
Evaluate the expression when x is 1
⇒ 3x + 2 = 3(1) + 2 = 3+2 = 5
2.)
Evaluate the expression when x is 4
⇒ 3x + 2 = 3(4) + 2 = 12+2 = 14

Step-by-step explanation:
the sum of 18 + 45 is a multiple of which sum? (3 + 9) (2 + 5) (1 + 3) (9 + 9)
Answer:
(2 + 5)
Step-by-step explanation:
First, calculate the sum of 18+45. This is 63.
Then, calculate all sums.
3 + 9 = 12
5 + 2 = 7
1 + 3 = 4
9 + 9 = 18
63/ 12 = 5.25
63/7 = 9
63/4 = 15.75
63/18 = 3.5
63/7 results in a positive integer, 9. All other values result in positive integers with decimals. Therefore, the sum of 5 + 2 has a multiple of the sum of 18 +45.
