Answer:

let the numbers be x and y then by given conditions:

x + y = 10 ….. eq 1

and

xy = 9….. eq 2

from eq 2. y = 9/x

put this in eq. 1

x + 9/x = 10

x + 9= 10x

x = 1

now,

xy = 9put value of x

y = 9

Answer:

yes; The triangles are congruent by hypotenuse-angle congruence.

Step-by-step explanation:

Answer: yes Question 6

There is not enough information to determine congruency

Question 9

yes; The triangles are congruent by hypotenuse-leg congruence

Step-by-step explanation:

* Lets revise the cases of congruence  

- SSS  ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ

- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and  

including angle in the 2nd Δ  

- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ  

≅ 2 angles and the side whose joining them in the 2nd Δ

- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles  

and one side in the 2ndΔ

- HL ⇒ hypotenuse - leg of the first right angle triangle ≅ hypotenuse

- leg of the 2nd right angle Δ

- HA ⇒ hypotenuse - angle of the first right angle triangle ≅ hypotenuse

- angle of the 2nd right angle Δ

- LL ⇒ leg - leg of the first right angle triangle ≅ leg - leg of the

2nd right angle Δ

* Now lets solve the problem

# Question 6

- There are two right angle triangles

- They have two different legs

- There is no mention abut legs equal each other

- There is no mention about hypotenuses equal each other

- There is no mention about acute angels equal each other

∴ There is not enough information to determine congruency

# Question 9

- There are two right angle triangles

- Their hypotenuse is common

- There are two corresponding legs are equal

∵ The hypotenuse is a common in the two right triangles

∵ Two corresponding legs are equal

- By using hypotenuse-leg congruence

∴ yes; The triangles are congruent by hypotenuse-leg congruence

Step-by-step explanation:

Property 5

RHS Criterion for Congruence

Explaining the congruence of triangles using RHS Criterion of Congruence

RHS Criterion stands for Right Angle-Hypotenuse-Side Criterion.

Under this criterion, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.

Important Notes

Two figures are congruent if they have the same shape and size.

Two angles are congruent if their measures are exactly the same.

Two triangles with equal corresponding angles may not be congruent to each other because one triangle might be an enlarged copy of the other. Hence, there is no AAA Criterion for Congruence.

Hope this helps have a nice day❤️

Answer: 8

Step-by-step explanation:

Answer: 8 pizzas.

Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Step-by-step explanation:

The formula for exponetial equation decay is

[tex]y = a(b) {}^{x} [/tex]

where a is the initial value and b is the decay factor.

A will be 56 since that our initial value.

b will be 0.9 since we are constantly decaying by 0.9.

so our equation is

[tex]y = 56(0.9) {}^{x} [/tex]

Answer:

[tex]x=27[/tex]

Step-by-step explanation:

The two angles are set within a right angle, so the sum of the two angles must equal 90 degrees. These two angles are known as complementary angles. Simply subtract 90 from 63 to get the missing angle measure of 27 degrees.

If this helped, a brainliest answer would be greatly appreciated!

if that is a 90 degree angles and it tells you that the bigger angle on the bottom is 63 degrees than the top angle would be 27 degrees.

Answer:

Folow the steps to learn what transformations were determined.

Step-by-step explanation:

First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.

X    Y

2    4

1     1

0    0

-1     1

-2    4

Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.

Vertical Shifts:

f(x) + c moves up,

f(x) - c moves down.

Horizontal Shifts:

f(x + c) moves left,

f(x - c) moves right.

The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Answer:

  the object’s mass

Step-by-step explanation:

The mass of the object will be the product of volume and density.

The object's mass can be calculated.

__

Knowing the volume, you know the amount of space the object takes up—no calculation is necessary. However, that is not enough information to calculate the size or shape.

Answer: the objects mass

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

x=-6

Step-by-step explanation:

Answer:

12/3 = 8/x

x=2

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation:

ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540

so we setup an equation which would be

7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x

step 1 combine like terms

7x+4x=11x

11x+4x=15x

15x+5x=20x

20x+6x=26x

5+10=15

15-5=10

10+10=20

now we have

20+26x=540

step 2 subtract each side by 20

20-20 cancels out

540-20=520

now we have 26x=540

the final step is to divide each side by 26

26/26 cancels out

540/26=20

x=20

hope this helps :D

370.85

Step-by-step explanation:

20.50×10. +165.85=

Answer:

$370.85

Step-by-step explanation:

He started off with $165.85. So all we need to do is multiply $20.50 x 10 = $205. We need to add 165.85 + 205 = $370.85

So after 10 weeks there will be $370.85.

Answer:

25x + 35(2x) = 380

25x + 70x = 380

95x = 380 so

Step-by-step explanation:

13 = -6(-2)+1

13=13 CORRECT

7 = -6(-1)+1

7=7 CORRECT

Answer:

C

Step-by-step explanation:

y = -6x + 1 so substitute the two answers given x = -1 and x = -2

when x = -1 then y = -6(-1) + 1 so y = 7 so (-1,7)

when x = -2 then y = -6(-2) + 1 so y = 13 (-2,13)
