A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?

Answers

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh  

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh  

15 = ½(10)h  

15 = 5h

Divide both sides by 5 to solve for h:

[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

Answers

Answer:

All Real Numbers

Step-by-step explanation:

First, use the distributive property to expand everything:

8v-6=10v-6-2v

Then, combine like terms:

8v-6=8v-6

Then, subtract 8v from both sides to isolate the variable:

0-6=-6

-6=-6

Any real number you substitute with v will make the equation always true, as -6 always is equal to -6. Therefore, the answer is All Real Numbers.

Alll that equals -6 hope this helps

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.

Answer:

126.5

Step-by-step explanation:

first, break the figure into a triangle and a square (do I have to tell u where)

the square: 11*8=88

the triangle: 11*7=77          77/2= 38.5

88+38.5= 126.5

The solution is, the area of the given figure is : 126.5cm^2.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

we need to find  the area of the given figure.

so, we have ,

first, break the figure into a triangle and a square

now, we get,

the square:

area= 11*8

       =88

and, we have,

the triangle:

area =1/2* 11*7

       =1/2*77          

       = 77/2

       = 38.5

so, we get,

the area of the given figure is:

88+38.5= 126.5

Hence, The solution is, the area of the given figure is : 126.5cm^2.

5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)
