Ben has a piece of plywood that measures 1 yard on each side.He cuts the wood into 6 equal pieces.Each piece is 1/3 yard wide and 1/2 yard long.What is the area of each piece that Ben cuts?
Answer:
The area is "[tex]\bold{\frac{1}{6}}[/tex]".
Step-by-step explanation:
In this question, to understand the problem we use the model, that Begins with drawing squares from each side which is 1 yard, and divides these as defined throughout the problem. To fix the issue, using the given model, please find the attached file.
Calculating the area of the one-piece:
[tex]=\frac{1}{2} \times \frac{1}{3}\\\\=\frac{1}{2\times 3}\\\\=\frac{1}{6}\\\\[/tex]
There are 10 marbles in a bag : 5 red and 5 blue she draws a marble from the bag at random. The marble is red. She put the marble back into the bag. What is the probability that next marble she draws at random is red ?
Answer:
1/ 2
Step-by-step explanation:
Given that:
Number of marbles, = 10
Number of Red marbles = 5
Number of Blue marbles = 5
Probability, p = required outcome / Total possible
Probability of picking a red marble :
Required outcome = number of red marbles = 5
Total possible outcomes = total number of marbles = 10
Hence,
Probability of picking a red marble, P(picking a red marble) = 5 / 10 = 1/2
Rewrite as a product of two factors: 3 + 18d + 21y
Answer:
[tex] \huge { \red{\boxed{ \boxed{ \tt \: 3(1 + 6d + 7y)}}}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:factoringlet's solve:in the following expression
everytime 3 is common
(3×1)+(3×6d)+(3×7d)
therefore if you take 3 from every expression we get
3(1+6d+7y)which is a product of two factors

A new laptop costs $1100 and has a new book value of $375 after 2 years. Find the linear model V(t)=Mx+b
Answer:
- 362.5t + 1100
Step-by-step explanation:
Given :
Value, = v ; time, = t
t1, v1 = (0, 1100)
t2, v2 = (2, 375)
Slope, m = v2 - v1 / t2 - t1
m = (375 - 1100) / (2 - 0)
m = - 725 / 2
m = - 362.5
v - v1 = m(t - t1)
v - 1100 = - 362.5(t - 0)
v - 1100 = - 362.5t
v = - 362.5t + 1100
There are 14 penguins on the rocks. Half as many are swimming. How many are in the water? How many in all?
Answer:
7 penguins are in the water.
21 penguins in all.
Step-by-step explanation:
14 penguins on the rocks.
Half of them equals 7 are in the water swimming.
7 + 14 = 21
7 penguins are in the water.
21 penguins in all.
The number of penguins in water = 7 penguins
The total number of penguins = 21 penguins
Word problems in mathematics involve a crucial understanding of solving real-life cases with the use of arithmetic operations.
From the information given:
There are 14 penguins on the rock.Half as many are swimming implies that: 7 of them are swimmingThus, the number of penguins in water = 7 penguins
The total number of penguins overall = penguins in water + penguins on the rock
The total number of penguins overall = 7 + 14
The total number of penguins overall = 21 penguins

what is the distance between (-6-4) and (-5,-4)
Step-by-step explanation:
take as if this points are on a line segment AB
Dab = square root of ( xa - xb) ^2 + ( y a- yb) ^2
= square root of [ (-6) - (-5) ]^2 + [ (-4) - (-4) ]^2
= square root of (-1)^2 + (0)^2
= square root of 1 + 0
= square root of 1
= 1 units
The distance from AB is 1 unit

Determinan las siguientes tablas muestran magnitudes directamente correlaciones o directamente proporcionales
Responder:
Los cuadros 89 y 91 presentan proporcionalidad directa
El cuadro 90 muestra una correlación directa.
Explicación paso a paso:
De la imagen adjunta:
Cuadro 89:
Para mostrar proporcionalidad directa:
y α x
y = kx; k = constante de proporcionalidad
Comprobando las tablas:
Cuadro 89:
A = 1,5; B = 3
B = kA; 3 = 1.5k
k = B / A
k = 3 / 1,5 = 2
Usando k = 2;
demuestre que B = 4 cuando A = 2; para establecer proporcionalidad directa.
B = 2 * 2 = 4
Por tanto, el cuadro 89 exhibe proporcionalidad directa
Comprobando las tablas:
Cuadro 90:
C = 2; D = 8
D = kC; 8 = 2k
k = 8/2 = 4
Usando k = 4;
demuestre que D = 9 cuando C = 3; para establecer proporcionalidad directa.
B
D = 4 * 3 = 12
De la tabla, D = 9;
Por tanto, el cuadro 90 presenta una correlación directa pero no una proporcionalidad directa.
Comprobando las tablas:
Cuadro 91:
E = 1; F = 1/2
F = kE; 1/2 = k
k = 1/2
Usando k = 1/2;
demuestre que F = 3/2 cuando E = 3; para establecer proporcionalidad directa.
F = 1/2 * 3 = 3/2
Por tanto, el cuadro 91 presenta proporcionalidad directa.

Five times a number is 28 greater than the product of the number and -2. Find the number
Answer:
4
Step-by-step explanation:
Let the unknown number be x
Five times the number is expressed as 5x
28 greater than the product of the number and -2 is expressed as;
28 + (-2x)
Equating both expressions
5x = 28 + (-2x)
5x = 28 - 2x
5x+2x = 28
7x = 28
x = 28/7
x = 4
Hence the number is 4

Find the interest earned from an investment of $14000 for 4 years at an interest rate of 6.85% compounded continuously. Round to the nearest cent.
Answer:
$4242
Step-by-step explanation:
Given data
Principal= $14000
TIme = 4 years
Rate= 6.85%
Let us find the final amount A
A=P(1+r)^t
substitute
A=14000(1+0.0685)^4
A=14000(1.0685)^4
A=14000*1.303
A=$18242
Hence the interest is
Interest= Final amount-Principal
=18242-14000
=$4242
