Answer:

68°

Step-by-step explanation:

since the angle given is a complementary angle, we know that the sum of it must equal 180°

let the unknown angle below j be x so,

[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]

now since the angle on the left of j is equal to x we can say

[tex]x+j=180\\j=180-x\\j=180-112\\j=68[/tex]

Answer:

81.57 cm

Step-by-step explanation:

Given that :

Scale :

3cm : 100km

This means ; 3cm on the map represents an actual length of 100km

Actual length of shoreline = 2719 km

The length of the shoreline on the map will be :

(2719 km / 100 km) * 3cm

27.19 * 3cm

= 81.57 cm

Answer:

81.57 cm

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

The computation is shown below:

Since she left with the amount of $74

Now in the case when the shoes cost is $65, taxes are $6.51 and the shipping cost is $3.19

So, the total cost is

= $65 + $6.51 + $3.19

= $74.70

But she has an amount of $74

So she dont have enough money to buy them as the total cost is more than the remianing amount

Answer: x= 30

Step-by-step explanation:

These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x

Answer:

60.4 degrees

Step-by-step explanation:

Complementary angles are 2 angles that add up to the sum of 90 degrees.

90-29.6=60.4 degrees

Answer:

22.5

Step-by-step explanation:

find the scale factor

13.5/9 = 1.5

or

18/12 = 1.5

Then times 15 by this to get x

15 x 1.5 = 22.5

Answer:

-13 = n - 4

Step-by-step explanation:

-13 is four less than a number n

so four less than n  can be written as n - 4

-13 = n - 4

n= -9

Answer:

(-6, -2)

Step-by-step explanation:

so, the coordinate of A is (-3,-1)

the scale factor is 2

you want to multiply the coordinate by the scale factor

(-3 x 2, -1 x 2)

(-6, -2)

(-6, -2) is your answer :)

Answer:

  4.3 in

Step-by-step explanation:

The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...

  f² = d² + e² -2de·cos(F)

  f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671

  f ≈ √18.0671 ≈ 4.2505

The length of f is about 4.3 inches.

Answer:

80

Step-by-step explanation:

Freddie is one meter shorter than his father

His father is 180 centimeters tall

So freddie is 80 centimetres

Freddie is mother÷2

So 80=M÷2

Mother is 190 centimeters

The number of centimeters when Freddie’s mother should be tall is considered to be 90.

Since

Freddie is half as tall as his mother.

Freddie is one metre shorter than his father.

Freddie’s father is 180 centimetres tall.

So

the Freddie is mother is

= 180 / 2

= 90

hence, The number of centimeters when Freddie’s mother should be tall is considered to be 90.

Answer:

the total weights in tons is 18

Step-by-step explanation:

The computation of the total weights in tons is shown below:

The weight of 8 cars would be

= 4,500 pounds × 8 cars

= 36,000 pounds

Now as we know that 1 ton = 2,000 pounds

So for 8 trucks it would be

= 36,000 pounds ÷ 2,000 pounds

= 18 tons

Hence, the total weights in tons is 18

Step-by-step explanation:

A pentagon's angle all add up to 540

[tex]460+x=540[/tex]

[tex]x=80[/tex]

Answer:A 80

Step-by-step explanation:

So a square is all 90° angles so take 90 from 140 and get 50 and 50+50=100 and a triangles thing adds up to 180 so 180-100=80 (I’m not good at explaining sorry)

75

Step-by-step explanation:

Answer:

it is 0.8

Step-by-step explanation: to get 56/70 converted to decimal you simply have to divide 56 by 70.

A)

45 degrees, and it is congruent.

90/2 = 45

Since it is an Alternate Interior, it is congruent.

B)

45 degrees. It is also congruent since it is an Alternate Exterior.

C)

135 degrees. It is a linear angle/linear pair.

180-45=135

Answer:

7

Step-by-step explanation:

We can simplify this because 6x - 3x is equal to 3x, so we get that the expression is 3x - y + 5. Next, we can plug in our values. 3 * 4 - 10 + 5 is equal to 12 - 10 + 5, which is 2 + 5, which is 7.

The value of the expression 6x - 3x + 5 - y at x = 4 and y = 10 is 7.

Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.

Given, An expression 6x - 3x + 5 - y.

Now, The value of the expression at x = 4 and y = 10 can be obtained by replacing the numerical values of x and y.

Therefore, 6x - 3x + 5 - y at x = 4 and y = 10 is,

6(4) - 3(4) + 5 - 10.

= 24 - 12 + 5 - 10.

= 12 - 5.

= 7.
