Mrs. Rios put a wallpaper border around the room shown below. She used 70 feet of wallpaper border. What is the unknown side length?

Answer: [tex]40h[/tex]

Step-by-step explanation:

Given

Speed of car is [tex]40\ mph[/tex]

We know, distance is given by

[tex]\text{Distance=}\text{speed}\times \text{time}[/tex]

Let h represents the number of hours

So, the distance traveled with speed [tex]40\ mph[/tex] in 'h' hours

[tex]\Rightarrow d=40\times h\\\Rightarrow d=40h[/tex]

So, the expression is given by [tex]40h[/tex]

Yes, it is better.

Step-by-step explanation:

3 oz. = $0.75

multiply each by 4

12 oz. = $3

Answer:

NO

Step-by-step explanation:

(4) 3oz bags are 12 ounces

0.75 * 4 = $3.00

So the 12 oz bag is not a good buy.

Answer:

The absolute value function:

f(x) = |x|

is defined as:

f(x) = x              if x ≥ 0

f(x) = -x             if x < 0.

Then, knowing that the elevation of the diver is -380 ft

We can write the absolute value of the distance as:

|-380ft| = -(-380ft) = 380ft

This means that the diver is at a distance of 380 ft from sea level. (And because we know that the sign is negative, we can conclude that he is 380ft below sea level).

Answer:

Y remains unchanged because y is still 7.

Answer:

Step-by-step explanation:

The given triangle is a right angled triangle.

So, the angles in the triangle are :

Solving according to angle sum property,

Sum of all angles in a triangle is 180°

[tex]\longrightarrow[/tex] 90° + (4x + 10)° + (2x + 26)° = 180°

[tex]\longrightarrow[/tex] 126° + 6x = 180°

[tex]\longrightarrow[/tex] 6x = 180° - 126°

[tex]\longrightarrow[/tex] 6x = 54°

[tex]\longrightarrow[/tex] x = 9

Angles =

[tex]\longrightarrow[/tex] 4(9) + 10

[tex]\longrightarrow[/tex] 46°

[tex]\longrightarrow[/tex] 2(9) + 26

[tex]\longrightarrow[/tex] 44°

The angles are 46°, 90° and 44°.

The point justifies the shaded area is (1, 1).

Thus, the standard equation of an ellipse is x²/ a² + y²/ b² = 1.

This equation defines an ellipse centered at the origin. If a > b , the ellipse is stretched further in the horizontal direction, and if b > a , the ellipse is stretched further in the vertical direction.

Given:

x²/ 16 + y²/ 4 ≤ 1

As, the given equation is in the form of an ellipse is x²/ a² + y²/ b² = 1.

Now, when we plot the Equation in the graph we get the elliptical shape.

From the given point the point which lies inside the graph is (1, 1).

B ) P 215 V 235

Peter 35×5=175+40=215

Veronica 35×5=175+60=235

Step-by-step explanation:

Let V be the volume of the cone.

The student says that, the volume of a cone with a 4-inch diameter is two times the volume of a cone with the same height and a 2-inch radius.

If diameter is 4 inch, radius = 2 inch

Volume of the cone,

[tex]V=\dfrac{\pi }{3}\times 2^2\times h\\\\V=\dfrac{4\pi h}{3}[/tex] .......(1)

If radius, r = 2 inch

New volume,

[tex]V=\dfrac{\pi }{3}\times 2^2\times h\\\\V=\dfrac{4\pi h}{3}[/tex] ....(2)

We can see that the volume in both case is same. Hence, the student is correct.

Answer:

Step-by-step explanation:

Numbers 1 and 4 are perimeter questions so all you do is add up all the sides and the label is cm. For #2, this is an area problem and the area for a rectangle is length times width, so multiply the 2 together and the label is inches squared. For #3, the volume formula for a cube is side*side*side and the label for this is feet cubed. For #5, the area for a triangle is .5 times the base times the height, and the label is mm-squared. That should help you get all the answers on your wn. Very, very simple.

Answer:

[tex]y=x[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=mx+b[/tex]

We're given that the slope of the line is 1. Plug this into the above equation

[tex]y=1x+b\\y=x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=x+b[/tex]

Plug in the given point (-7,-7)

[tex]-7=-7+b[/tex]

Add 7 to both sides to isolate b

[tex]-7+7=-7+b+7\\0=b[/tex]

Therefore, the y-intercept is 0. Plug this back into [tex]y=x+b[/tex]

[tex]y=x+0\\y=x[/tex]
