What is the base if the height is 6ft and the area is 14 ft on a triangle ​

Mathematics
1 answer:

4 0

Answer:

b = 4.66666667

Step-by-step explanation:

The equation for finding the area of a triangle is

0.5b x h = a

b = base

h = height

a = area

So I calculated 14 divided by 6

And got 2.3333333

And since that number is half of the base, I multiplied it by 2

2.333 x 2 ≈ 4.66666667

Let u = <-7, -2>. Find 4u.
Katena32 [7]

Answer:

a. <-28, -8>

Step-by-step explanation:

The given vector is

u = <-7, -2>.

To find 4u, we multiply the given vector by the scalar 4.

4u =4 <-7, -2>.

4u =<-7\times4, -2\times4>.

We multiply out to get;

4u =<-28, -8>.

The correct choice is a. <-28, -8>

WILL GIVE BRAINLIEST
Mnenie [13.5K]

Answer:

C

Step-by-step explanation:

Given the 2 equations

3x + 4y = 8 → (1)

y - 5x = 2 ← rewrite as

- 5x + y = 2 → (2)

Multiplying (2) by - 4 and adding to (1) will eliminate the y- term

20x - 4y = - 8 → (3)

Add (1) and (3) term by term to eliminate y

23x + 0 = 0

23x = 0 , then

x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (1)

3(0) + 4y = 8

4y = 8 ( divide both sides by 4 )

y = 2

solution is (0, 2 )

That is the lines intersect once at (0, 2 )

what is the total surface area of the garden in inches, feet and yards that is 70 ft long and 45 wide?
arlik [135]
So,

First, we will find the surface area of the garden in feet.
(70)(45) = 3150 square ft.

Next, to find the surface area of the garden inches, we need to recall the conversion rate between feet and inches.
1 ft. = 12 in.

So, multiply 3150 by 12.
(3150)(12) = 37,800 square in.

To find the surface area of the garden in yards, we need to recall the conversion rate between yards and feet.
1 yd. = 3 ft.

So, divide 3150 by 3.
\frac{3150}{3} = 1050\ square\ yd.

Area of the garden in inches: 37,800 square in.
Area of the garden in feet: 3150 square ft.
Area of the garden in yards: 1050 square yd.
