Find the gradient and intercept on the x and y axes of the straight line with the following equation.

PilotLPTM [1.2K]

Answer:

gradient is 5

Step-by-step explanation:

x intercept, replace y with 0

y +5x= 13

0+ 5x =13

0 - 13= -5x

-13= -5x

-13/-5 = -5x/-5

x = 13/5

y intercept, replace x with 0

y+5x=13

y+5(0)=13

y+0=13

y =13

Find the values of the variables ( I have five more of these if you will help me pls)

lord [1]

The angles of the figure are complementary, that is, the sum between them is equal to 90º.

Solving:
54º + 4xº = 90º
4xº = 90 - 54º
4xº = 36º
 $x = \frac{36^0}{4^0}$
$\boxed{\boxed{x = 9^0}}\end{array}}\qquad\quad\checkmark$

We have:
54º + 4.xº = 90º
54º + 4.(9º) = 90º
54º + 36º = 90º
90º = 90º (TRUE)

Answer:
The value of the variable is 9º

How do I calculate the shaded area of this shape ?

TEA [102]

SOLUTION:

We are to calculate the shaded area of the given shape.

CONCEPT:

This is a triangle that a rectangle was cut out from.

To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.

$\begin{gathered} \text{Area of Triangle:} \\ A\text{ = }\frac{1}{2}\text{ base }\times\text{ height} \\ \\ A\text{ = }\frac{1}{2}\text{ }\times\text{ 6m }\times7m\text{ } \\ \\ A=21m^2 \end{gathered}$ $\begin{gathered} \text{Area of Rectangle:} \\ A=L\text{ }\times\text{ W } \\ A\text{ = 4m }\times\text{ 2m} \\ A=8m^2 \end{gathered}$

The shaded area = Area of the triangle - Area of the rectangle

$\begin{gathered} \text{Shaded area = 21 m}^2-8m^2 \\ \text{Shaded area = 13 m}^2 \end{gathered}$

The diameter of the cone is 6 inches. It’s height is 4 inches. What is its slant height?

Kisachek [45]

Answer:

5 inches

Step-by-step explanation:

As the height is perpendicular to the base, the radius and the height form a right angle, creating a right triangle where the slant height is the hypotenuse, thus:

$(height)^2+(radius)^2=(slant\:height)^2$

$4^2+(6/2)^2=(slant\:height)^2$

$16+9=(slant\:height)^2$

$25=(slant\: height)^2$

$5=slant\: height$

In conclusion, the slant height of the cone is 5 inches. See below for a visual.
