What Is The Perimeter Of The Triangle?218X

Answers

Answer 1

Answer:

Step-by-step explanation:

P=a+b+c

Right scalene triangle.

Sides: a = 21   b = 8   c = 22.472

Area: T = 84

Perimeter: p = 51.472

Semiperimeter: s = 25.736

Angle ∠ A = α = 69.146° = 69°8'44″ = 1.207 rad

Angle ∠ B = β = 20.854° = 20°51'16″ = 0.364 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 8

Height: hb = 21

Height: hc = 7.476

Median: ma = 13.2

Median: mb = 21.378

Median: mc = 11.236

Inradius: r = 3.264

Circumradius: R = 11.236

Vertex coordinates: A[22.472; 0] B[0; 0] C[19.624; 7.476]

Centroid: CG[14.032; 2.492]

Coordinates of the circumscribed circle: U[11.236; -0]

Coordinates of the inscribed circle: I[17.736; 3.264]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 110.854° = 110°51'16″ = 1.207 rad

∠ B' = β' = 159.146° = 159°8'44″ = 0.364 rad

∠ C' = γ' = 90° = 1.571 rad

4) A zoologist was checking the weights of three gorillas. Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?​

Answers

Answer:

1,516 pounds

Step-by-step explanation:

Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds

Total weight of the gorillas = gorilla A + gorilla B + gorilla C

= 559 pounds + 827 pounds + 130 pounds

= 1,516 pounds

Total weight of the gorillas = 1,516 pounds

what's the factor of 18 and the sum of -9?

Answers

Factor:-6,-3
-6-3= -9

Answer:

Do you really mean by -9 or cause I'm just confused but if you meant by 19 then this could help. I had my mom do whatever she could put as  the answer so yeah

Step-by-step explanation:

a*b=18 ____[1]

a+b=19____[2]

[2] a=19-b ___[3]

put [3] in [1]

(19-b)*b = 18

19b-b^2 = 18

b^2-19b+18 = 0

(b-18)(b-1) = 0

so b=18 or b=1

if b=18 then a=19-18=1

if b=1 then a=19-1=18

SO two factors are 1 and 18

What is the distance between two points(0,0)(-3,5)

Answers

Step-by-step explanation:

Think of it like a right triangle. Do you have a graph handy?

Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.

Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?

All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.

which inequality is graphed in red

Answers

Answer:

y>x-2

Step-by-step explanation:

When we see an inequality on a coordinate plane, we first treat it like a linear equation. The red inequality, or the red line, clearly has a positive slope. One can assume that this slope is 1. This line is also 2 units down, making the inequality x-2. There you have it!

Furthermore, we can tell it is the 1st choice because the line is dashed. In inequalities, the line is only dashed when the inequality contains < or >. Also, the shading is "above" the line, meaning the y must be greater than the line.

The height of the square pyramid is 24 unit.

Step-by-step explanation:

Given that:

Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unit

To Find:

The height of the square pyramid.

We know that:

In pythagoras theorem.

H² = P² + B²

Where,

H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unit

Finding the height of the square pyramid:

⇒ H² = P² + B²

⇒ (25)² = x² + (7)²

⇒ 625 = x² + 49

⇒ x² = 625 - 49

⇒ x² = 576

⇒ x = √576

⇒ x = 24

Hence,

The height of the square pyramid = 24 unit

Joe and Steve went to a chocolate shop and got some fudge. The fudge cost $32 per kilogram. Joe ordered 75 grams of fudge. Steve ordered 235 grams of fudge. How much did each person pay? How much MORE did Steve pay than Joe?

Answers

Answer: Joe paid $2.4; Steve paid $7.52

Steve paid $5.12 more than Joe

Step-by-step explanation:

Cost of I Kg fudge = $32

But we know that 1 kg =1000g

That is to now say that

Cost of  1000g of fudge = $32

a)

If Joe ordered 75 grams of fudge then he paid

Now 1000g of fudge = $32

75g  of fudge will cost =75 x 32 /1000 =$2.4

also .

b) 235 grams of fudge ordered by Steve will cost

235 x 32 / 1000=$7.52

Therefore, Steve paid $5.12 ($7.52-$2.4)  more than Joe

find a:c and a:b:c of a:b =4:5, b:c=3;5
pls ans with explanation ​

Answers

Here's the solution,

a : b = 4 : 5

b : c = 3 : 5

now, we can combine the ratios if the value of b is equal in both of them, and we have to make sure it's the minimum value since we have to obtain it in the simplest form, so let's take the L.C.M of b in both proportions .

L.C.M of b in both ratios is 15

so

ratio 1.)

a : b = 4 : 5 a : b = 12 : 15

( just multiplied both numbers by 3 to make b = 15 )

ratio 2.)

b : c = 3 : 5b : c = 15 : 25

( just multiplied both numbers by 5 to make b = 15)

now, simply combine the equations to get,

a : b : c = 12 : 15 : 25

and hence,

a : c = 12 : 25
