Mike needs to replace the carpet in his living room. The carpet he likes costs $7.50 per square foot to purchase and install. His living room measures 263.5 square feet. How much will it cost to replace the carpet?
Answer:
$1,976.25

John, Jack, Jim, and Joe all decided to take up horseback riding. Jim went twice as many times as Jack, and John went four more times than Joe but three less times than Jim. Joe went 15 times altogether. How many times did Jack go?
Answer:
11 times
Step-by-step explanation:
Given
[tex]Jim = 2 * Jack[/tex]
[tex]John = 4 + Joe[/tex]
[tex]John = Jim - 3[/tex]
[tex]Joe = 15[/tex]
Required
Find [tex]Jack[/tex]
Substitute [tex]Joe = 15[/tex] in [tex]John = 4 + Joe[/tex]
[tex]John = 4 + 15[/tex]
[tex]John = 19[/tex]
Substitute [tex]John = 19[/tex] in [tex]John = Jim - 3[/tex]
[tex]19 = Jim - 3[/tex]
Collect like terms
[tex]Jim = 19 +3[/tex]
[tex]Jim = 22[/tex]
Substitute [tex]Jim = 22[/tex] in [tex]Jim = 2 * Jack[/tex]
[tex]22 = 2 * Jack[/tex]
Divide both sides by 2
[tex]Jack = \frac{22}{2}[/tex]
[tex]Jack = 11[/tex]

use the circle to answer the questions
Answer:
Diameter: 10.8 cm
Circumference (in terms of π): 10.8π cm
Circumference (approximate): 33.91 cm
Step-by-step explanation:
Hi there!
We're given:
The radius (5.4 cm)1) Determine the diameter
[tex]d=2r[/tex]
Multiply the radius 5.4 cm by 2
5.4 × 2 = 10.8
Therefore, the diameter of the circle is 10.8 cm.
2) Determine the circumference of the circle
[tex]C=\pi d[/tex]
Plug in the diameter 10.8
[tex]C=10.8\pi[/tex]
Therefore, the circumference of the circle in terms of π is 10.8π cm.
3) Determine the approximate circumference of the circle
[tex]C=10.8\pi\\C=10.8(3.14)\\C=33.91[/tex]
Therefore, the approximate circumference of the circle is 33.91 cm.

Find the gradient of the line 2y = -10x + 1
Answer:
Gradient = -5
Step-by-step explanation:
The gradient of a line is the slope of the line.
The standard form of the line equation is y = mx + b
where m is the slope ( or gradient) b is the y - intercept.
Given :
2y = -10x + 1
[tex]y = -\frac{10}{2} x + \frac{1}{2}\\\\y = -5x + \frac{1}{2}\\\\Therefore , \ gradient \ is \ -5[/tex]
The gradient of the line whose equation is 2y=-10x+1 is -5.
What is gradient?Gradient could be a measure of how steep a slope or a line is.
How to calculate the gradient of the line?The equation of the road is 2y=-10x+1
y=-5x+1/2
Therefore the gradient of the line is that the coefficient of x which is -5.
Hence the gradient of the line is -5.

What is the constant of proportionality in the equation y=\dfrac{5}{9}xy= 9 5 xy, equals, start fraction, 5, divided by, 9, end fraction, x? constant of proportionality ==equals
Answer:
5/9
Step-by-step explanation:
If a variable y is directly proportional to x, then;
y = kx where;
k is the constant of proportionality
Given the expression y = 5/9 x
On comparing with the general formula;
kx = 5/9 x
k = 5/9
Hence the constant of proportionality of the expression is 5/9

Find the area of the sector
Find the area of the full circle:
Area = pi x r^2
Area = 3.14 x 17^2
Area = 907.46 square units
A full circle is 360 degrees. The sector is 120degrees.
Multiply the area of the circle by the sector degrees/ full circle degrees
907.46 x 120/360 = 302.486 square units round off as needed.
Answer:
289/3[tex]\pi[/tex] m² or 302.6400923... m²
Step-by-step explanation:
These type of questions are very simple, you just have to know how to approach them properly. I'll give you the general structure using this as an example for your understanding.
The general structure goes like this:
Find the area of the entire circleUsing the angle, find out how much of the circle is covered by the sector.Multiply answer from Step 2 from the area to figure out the area of the sector.Area of a circle is [tex]\pi r^{2}[/tex], so [tex]\pi[/tex]×17² = 289[tex]\pi[/tex] m²
The angle is 120° out of 360°, think of a sector as the percentage of the area of the circle.
120/360 = 1/3
1/3 × 289[tex]\pi[/tex] = 289/3[tex]\pi[/tex] m² or 302.6400923... m²
What is the value of x in the following equation? 11^4x+1= 11^3x-7
Answer:
-8
Step-by-step explanation:
well since the equation has the same base of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
subtract one from both sides
4x = 3x - 8
subtract 3x from both sides
x = - 8
Answer:
x= -8

Answer:
The values of [tex]a[/tex] and [tex]b[/tex] are [tex]33[/tex] and [tex]\frac{20\sqrt{3}}{3}[/tex], respectively.
Step-by-step explanation:
The statement is equivalent to the following mathematic expression:
[tex]\left(5 + 2\sqrt{2})^{2} = a + b\cdot \sqrt{6}[/tex] (1)
By definition of the perfect square trinomial:
[tex]25 + 20\cdot \sqrt{2} + 8 = a + b\cdot \sqrt{6}[/tex]
[tex]33 + 20\sqrt{2} = a + b\cdot \sqrt{6}[/tex]
And by direct comparison we have the following system:
[tex]a = 33[/tex] (2)
[tex]b\cdot \sqrt{6} = 20\sqrt{2}[/tex] (3)
By (3), we solve for [tex]b[/tex]:
[tex]b = \frac{20}{\sqrt{3}}[/tex]
[tex]b = \frac{20\sqrt{3}}{3}[/tex]

Lines J and k intersect at point Q and h is a straight line. What is the value of X ?
Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 so 180-135 equals 45. Vertically opposite angles are equal so the second angle inside the triangle equals 100. Henceforth, we can solve this equation:
x +45+100 = 180 (angles in triangle add up to 180)
x+145=180
x=35
Vertically opposite angles are equal so x will become 35.
Hope this helps!

Tarea 9 (Expresiones algebraicas) entrega 31/5/2021 Copiar en el cuaderno de clase y plantear la ecuación Plantea una ecuación para cada situación Juan compró 2 panchos y 3 hamburguesas y le cobraron $ 330 Realizo un pago de la factura de luz, agua y cable en total me cobran $ 3890 Un padre reparte un dinero X que recibió entre su esposa y su hijo, a su esposa le da el doble que al hijo. En el salón de clase hay 27 alumnos entre mujeres y varones.
Answer:
1-
2X + 3Y = 330
2-
X + Y + Z = 3890
3-
1/3X + 2/3X = X
4-
X + Y = 27
Step-by-step explanation:
Para plantear ecuaciones para las siguientes situaciones se deben realizar los siguientes razonamientos lógicos:
1- Juan compró 2 panchos y 3 hamburguesas y le cobraron $330.
Panchos = X
Hamburguesas = Y
2X + 3Y = 330
2- Realizo un pago de la factura de luz, agua y cable en total me cobran $3890.
Luz = X
Agua = Y
Cable = Z
X + Y + Z = 3890
3- Un padre reparte un dinero X que recibió entre su esposa y su hijo, a su esposa le da el doble que al hijo.
Esposa = 2/3X
Hijo = 1/3X
1/3X + 2/3X = X
4- En el salón de clase hay 27 alumnos entre mujeres y varones.
Mujeres = X
Varones = Y
X + Y = 27
