Please help meeeeee

Answers

Answer:

a. m<DAB = 36°

b. m<B = 54°

c. m<C = 74°

Step-by-step explanation:

a. m<DAB = m<CAB + m<CAD

m<DAB = 20° + 16° (substitution)

m<DAB = 36°

b. m<B = 180° - (90° + m<DAB)

m<B = 180° - (90° + 36°) (substitution)

m<B = 54°

c. m<C = 180° - (90° + m<CAD)

m<C = 180° - (90° + 16°) (substitution)

m<C = 74°

what is the difference between associative property,communitive property,and distributive property? (will mark brainliest)

Answers

Answer:

Commutative switches the numbers, while associative keeps the numbers positions but changes the parentheses. I hope that helped

The associative property only changes the grouping and keeps the same order. Example- (2+3)+(4+5) -> 2+(3+4)+5
The communities property changes the order only. Example- 3+2 -> 2+3
The distributive property distributes the number from the outside of the parenthesis to the numbers inside
Example- 4(5+3) so you distribute the 4 to the 5 and 3 by multiplying. The answer would be 20+12

Determine the solution to the system of equations below: y = -3x + 6 and 3y = -2x - 3

Answers

Answer:

x = 3

y = -3

Step-by-step explanation:

We have two equations and are asked to solve for x and y.

y = -3x + 6

3y = -2x - 3

Substitute the y in the first equation in the second equation :

3(-3x + 6) = -2x - 3

Distribute :

-9x + 18 = -2x - 3

Solve for x by isolating it :

Subtract 18 from both sides :

-9x = -2x - 21

Add 2x to both sides :

-7x = -21

Divide -7 from both sides :

x = 3

Replace x in the first equation :

y = -3(3) + 6

y = -9 + 6

-9 + 6

y = -3

Answer:

1402 tiles

Step-by-step explanation:

so in order to find the amount of glass tiles we will first need to find the surface area of the box

so the surface area formula for a rectangular prism is

2 (wl * hw* hl)

w- width

h- height

l- length

so the width would be 18centimeters

the height would be 7 cm

and the length would be 23 cm

therefore if we plug in the measurements into the equation it will give us a total surface area of

1402cm^2

therefore if Dimitri wants to cover the box with 1cm glass tiles then we take the 1402cm and divide it by 1cm leaving us with the same answer of

1402 tiles

10 meaning the biggest number and then subtract by 4 since it’s the lowest number and you get 6.

Answer:

10-4=6

Step-by-step explanation:

The range is the difference between the biggest and smallest number. In this case, 10 is the biggest number and 4 is the smallest. So we do 10-4, which gives us 6, so 6 is the range.

x=28

m<ACD=68°

Step-by-step explanation:

2x+(180-124)+(180-4x)=180

-2x+236=180

-2x=180-236

-2x=-56

x=28

m<ACD=180-4x=180-4(28)=180-112=68

Answer:

The answer is <ACD = 68°

Step-by-step explanation:

Using the property that the sum of interior angles in a triangle is equal 180°,we have:

<DAC + <ACD + <ADC = 180°

[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]

Finally, calculating the angle <ACD, we have:

<ACD = 180 - 4x

<ACD = 180 - 4 . 28

<ACD = 180 - 112

ACD = 68°

Answer:  127 (choice D)

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

Explanation:

We can apply the remote interior angle theorem.

The exterior angle DFG is far away from the remote interior angles FGH and GHF. In other words, the exterior angle is not adjacent to these remote interior angles.

The remote interior angles add to this exterior angle.

(angle FGH) + (angle GHF) = angle DFG

(89) + (5x-7) = 14x+1

5x + 82 = 14x + 1

82-1 = 14x-5x

81 = 9x

9x = 81

x = 81/9

x = 9

If this is the case, then,

angle DFG = 14*x+1 = 14*9+1 = 127

A sea turtle descends 28 feet from the surface of the ocean and then ascends 5 feet. Then it descends 9 feet and repeats this descent 4 times. How many feet below the surface is the turtle then ?

Answers

Answer: 59 feet

Step-by-step explanation:

First the sea turtle descended 28 feet.

It then ascends 5 feet which means it is now:

= 28 - 5

= 23 feet below surface

It then descends 9 feet and repeats that descent 4 time:

= 9 * 4

= 36 feet below the surface

Total distance below the surface:

= 23 + 36

= 59 feet
