Answer:

  obtuse scalene triangle

Step-by-step explanation:

Connecting 3 points will make a triangle. The sides are different lengths, and the largest angle is more than 90°. The figure is an obtuse scalene triangle.

[tex]4(5 {)}^{2} + 3(6)[/tex]

[tex]4 \times 25+3(6)[/tex]

[tex]100+3(6)[/tex]

[tex]100+18[/tex]

[tex]118[/tex]

Answer:

YZ cannot be determined from the similar triangles

Step-by-step explanation:

Given two similar triangles, to get any sides of the triangles, the ratio of their congruent sides is equal to a constant, Hence;

AB/XY = AC/XY

Also, BC/YZ = AB/XY

This shows that to get YZ, both BC and XY must be given. Since we are not given either of the two sides hence YZ cannot be determined from the similar triangles

Answer:

[tex]\sqrt{(4-a)(4+a)} =b[/tex]

Step-by-step explanation:

16 = a^2 + b^2

16 - a^2 =b^2

4^2 - a^2 = b^2

[tex]\sqrt{4^2 - a^2} =b[/tex]

[tex]\sqrt{(4-a)(4+a)} =b[/tex]

Answer:

v=24

Step-by-step explanation:

V= 3[tex]\sqrt{10^{2} - 6^{2} }[/tex]

V= 3[tex]\sqrt{100-36}[/tex]

V= 3[tex]\sqrt{64}[/tex]

V= 3×8

V= 24

Answer:

4(19x + 42n + 15)

Step-by-step explanation:

Devi bought 7 skirts at $x each, n skirts at $12 each, (2n + 1) skirts at $15 each and 4 skirts at $3x each. Find the total cost of the skirts she bought.​

total cost of the skirt bought can be determined by adding the  total costs of each shirt bought

7 skirts at $x each = $7x

n skirts at $12 each = $12n

(2n + 1) skirts at $15 = (2n + 1) x 15 = 30n + 15

4 skirts at $3x each = $12x

7x + 12n + 30n + 15 + 12x

combine like terms

19x + 42n + 15

Answer:

2.86

Step-by-step explanation:

So I'm pretty sure we don't want the probability, just the zscore

to find the zsore subtract the mean and divide by the standard deviation

(93-87)/2.1= 2.86

Answer:

33/20

Step-by-step explanation:

I dont know if that was a minus or a plus but it looked like a minus sorry if its wrong

Answer:

0.475

Step-by-step explanation:

It makes it easier for people to turn fraction to decimal.

So, 1/4 in decimal is 0.25.

1.9•0.25=0.475

Sorry if I'm wrong I'm in 8 grade I learned it in this year

Answer:

I dont understand that sorry

Step-by-step explanation:

the answer is 4 and 64

please give me brainliest

Answer:

AC ≈ 11.0 cm

Step-by-step explanation:

Using Pythagoras' identity in Δ CDE and Δ ADE

CE² + DE² = DC²

CE² + 7² = 8²

CE² + 49 = 64 ( subtract 49 from both sides )

CE² = 15 ( take the square root of both sides )

CE = [tex]\sqrt{15}[/tex]

-------------------------------------------------------

AE² + DE² = DA²

AE² + 7² = 10²

AE² + 49 = 100 ( subtract 49 from both sides )

AE² = 51 ( take the square root of both sides )

AE = [tex]\sqrt{51}[/tex]

Then

AC = AE + CE = [tex]\sqrt{15}[/tex] + [tex]\sqrt{51}[/tex] ≈ 11.0 cm ( to the nearest tenth )

Given:

The figure of a right triangle.

To find:

The value of x.

Solution:

In a right triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In the given right angle triangle,

[tex]\tan 52^\circ=\dfrac{x}{35}[/tex]

[tex]1.2799\times 35=x[/tex]

[tex]44.7965=x[/tex]

Approximate the value to two decimal places.

[tex]x\approx 44.80[/tex]

Therefore, the value of x is about 44.80 units.

(x), (x-2), (x-5), (x-5), (x-7) and (x-9) are NOT zeros, they are FACTORS. The zeros are 0, 2, 5, 5, 7, and 9. Since 5 is listed twice it is said to be a zero of multiplicity 2. To find a polynomial with those zero, we start by setting x equal to each zero: x=0, x=2, x=5, x=5, x=7, and x=9. Then we subtract the zero on the right from both sides of each of those 6 equations: x-0=0, x-2=0, x-5=0, x-7=0, x-9=0 Then we use the principle that equals multiplied by equals gives equals. So we multiply all the left sides together and all the right sides together. (Multiplying all the right sides together just gives 0.) (x-0)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 And since x-0 is just x, we have (x)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 Those are the factors you gave. But again, the zeros are 0,2,5,5,7,9

Answer:

5

Step-by-step explanation:

13u - 8u = 25

5u = 25

u = 5

Answer:

u = 5

Step-by-step explanation:

13u - 8u = 25

combine 13u and 8u to get 5u.

5u = 25

divide each side by 5

5u/5 = 25 /5

u = 5

==========================================================

Explanation:

If you apply the distance formula, you should find that triangle DEF has the following side lengths

Those distances are exact. The sqrt(50) approximates to 7.071

Since 7.071 is the longest side, we'll make c = sqrt(50)

Then we have a = 5 and b = 5

Note that a^2+b^2 = 5^2+5^2 = 50 while c^2 = (sqrt(50))^2 = 50

Both a^2+b^2 and c^2 are equal to 50.

That means a^2+b^2 = c^2 is a true equation for the a,b,c values mentioned.

By the converse of the pythagorean theorem, we have shown that triangle DEF is a right triangle.

---------------

Side notes:

Answer:

right

Step-by-step explanation:

we should find the distance of

DE

EF

FD

for DE

D(2,3) = (x1,y1)

E(5,7) = (x2,y2)

disatnce = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(5-2)^2 + (7-3)^2}[/tex]

=[tex]\sqrt{3^2 + 4^2}[/tex]

=[tex]\sqrt{16+9}[/tex]

=[tex]\sqrt{25}[/tex]

=5 units

for EF

E(5,7) = (x1 , y1)

F(9,4) = (x2 , y2)

distance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(9-5)^2 + (4-7)^2}[/tex]

=[tex]\sqrt{(4)^2 + (-3)^2}[/tex]

=[tex]\sqrt{16 + 9}[/tex]

=[tex]\sqrt{25}[/tex]

=5 units

for DF

D(2,3) = (x1 , y1)

F(9,4) = (x2 , y2)

diatance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(9-2)^2 + (4-3)^2}[/tex]

=[tex]\sqrt{7^2 + 1^2}[/tex]

=[tex]\sqrt{49 + 1}[/tex]

=[tex]\sqrt{50}[/tex]

=[tex]5\sqrt{2}[/tex]

It is a right angle triangle .

to prove right angle triangle

sum of square of two smaller sides = sum of square of longest side

5^2 + 5^2 =[tex](5\sqrt{2})^2[/tex]

25 + 25 = 52 *2

50 + 50

hence proved.

Answer:

A. 5 × ( 3 + 2 + 2 1/4 )

Step-by-step explanation:

Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1/4 -mile path.

The expression represents the total number of miles he biked is calculated as:

The number of times he rode his bike × (sum of the number of miles he biked)

= 5 × ( 3 mile + 2 miles + 2 1/4 miles)

= 5 × (3 + 2 + 2 1/4)

Therefore, Option A is the correct option

Answer:

a^8

Step-by-step explanation:

When dividing exponents simply subtract the exponents and keep the base the same

So a^10 / a^2

Subtract the exponents

10-2=8

And keep the base

We would get a^8
