Answer:

Step-by-step explanation:

a). Let the unknown side of triangle A = x cm

And unknown side of triangle B = y cm

By applying Pythagoras theorem in triangle A,

13² = 12² + x²

x² = 169 - 144

x² = 25 ⇒ x = 5 cm

By applying Pythagoras theorem in triangle B,

y² = 5² + 12²

y² = 25 + 144

y = √169

y = 13 cm

Therefore, smaller sides of these triangles measure 5 cm and 12 cm and they are same in measure.

b). Since, corresponding sides of both the triangles are congruent,

By SSS property of congruence, both the triangles will be congruent.

Answer:

it´s no

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

Given:

The expression is

[tex]-9xy^2z[/tex]

To find:

The coefficient of x in the given expression.

Solution:

Coefficient of a variable is the product of a number and other variables multiplying the variable in an algebraic expression.

In the given expression the number and variables other than x are -9, y² and z.

So, coefficient of x is

[tex]-9\times y^2\times z=-9y^2z[/tex]

Therefore, the correct option is (d).

Answer:

≈ 50.7 cm²

Step-by-step explanation:

The area (A) of Δ XYZ is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is

A = [tex]\frac{1}{2}[/tex] × XY × YZ

Calculate YZ using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )

11 × tan40° = x , that is

YZ ≈ 9.23 cm

Thus

A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

Answer:

exact form: x=17/10

Decimal form: x=1.7

mixed number form: 1 7/10

Answer:

x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)

Step-by-step explanation:

3(5-x) = 7x - 2

3 * 5 - 3* x = 7x - 2 (brackets means multiply)

15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

15 + 2 = 7x + 3x

17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)

17/10 = x

Answer:

[tex]\frac{15}{10}[/tex]  and [tex]\frac{3}{10}[/tex]

 [tex]\frac{15}{10} -\frac{12}{10} = \frac{3}{10}[/tex]

Step-by-step explanation:

Given

       [tex]\frac{3}{2} - \frac{6}{5}[/tex]

Now the L.C.M = 10

 =  [tex]\frac{15-12}{10}[/tex]

 =  [tex]\frac{15}{10} -\frac{12}{10} = \frac{3}{10}[/tex]

Answer:

Step-by-step explanation:

8/16=8:16

2/4=2:4

Answer:

Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.

Answer:

ATQ= 15 is 1/5 and 312 is 3/12 sorry for that

1/5(N-10)=6-3/12

1/5N -2= 6/1 - 3/12

1/5N-2 = 72 -3/12 = 69/12

69/2 = 5.75

1/5N = 5.75-2 = 3.75

N= 3.75/.2

18.75

Answer:

8,403.6

Step-by-step explanation:

6/5 of 7003

= 6/5 × 7003

= 42,018/5

= 8,403.6

Hence 6/5 of 7003 is 8,403.6

Answer:

a). Distance round one loop = 141.37 meters

b). Distance covered = 3534.29 meters

Step-by-step explanation:

Diameter of the given track = 45 meters

a). Distance round one loop of the track = circumference of the circle

    Circumference of a circle = π × (Diameter)

                                               = π × (45)

                                               = 141.37 meters

b). Distance covered by going around the track 25 times = 25 × distance in one loop of the track

    = 25 × 141.37

    = 3534.29 meters

Answer:

x=7

Step-by-step explanation:

You should first write an equasion to represent the question.

There are 2 ways you can write this → x+2+x+2+7+7 or 2(x+2)+2(7)

Then Simplify = To check the answer plug the answer back in ->14+4+14=32

2x+4+14=32

2x+18=32

2x=(32-18)

2x=14

Step-by-step explanation:

Step-by-step explanation:

c + 13 = - 17

c = - 17 - 13

Therefore c = -30

Hope it will help :)

Answer:

c is equal to negative thirty.

Step-by-step explanation:

You can find out what c is by subtracting 13 from both sides of the equation:

c + 13 = -17

c + 13 - 13 = -17 - 13

c + 0 = -30

c = -30
