Answer:

To find c° go with Triangle Sum Theorem .

To find d° go with Supplementary Angle with 58°.

To find a° go with Transverse Angles.

To find b° go with Transverse Angles .

Step-by-step explanation:

c° = 180- 58 - 48 = 74°

b° = 48°

d° = 180 - 58 = 122°

a° = 58°

Answer:

21ml/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Adding the two equations together gives you

9x-10y-9x-6y=145+15

-16y=160

y=-10, using this value in 9x-10y=145 gives you

9x-10(-10)=145

9x+100=145

9x=45

x=5

So y=-10 and x=5

Answer:

A) triangles A and B

Step-by-step explanation:

Their dimensions are proportional and their angles are equal

Answer:

the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

Step-by-step explanation:

The computation of the average acceleration is shown below:

= Change in velocity ÷ change in time

= 5 - 3 ÷ 4

= 2 ÷ 4

= 0.5 m/sec ^2

Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

Step-by-step explanation:

Answer: 463.96 mm² or 46.4 cm²

Step-by-step explanation:

Quarters are circular in shape so the surface area of one side will be the area of a circle.

Area of a circle = π * r²

Radius = Diameter / 2

= 24.3 / 2

= 12.15 mm

Area = 22/7 * 12.15²

= 463.96 mm²

Answer:

Answers provided below

Step-by-step explanation:

From the simultaneous linear equation, we have the coefficient matrix as;

(3 4 5)

(2 -1 8)

(5 -2 7)

The x-matrix is Dx is given by;

(18 4 5)

(13 -1 8)

(20 -2 7)

Similarly, the y-matrix Dy is given by;

(3 18 5)

(2 13 8)

(5 -20 7)

Also,the z-matrix Dz is given by;

(3 4 18)

(2 -1 13)

(5 -2 -20)

Determinant of the coefficient matrix from online determinant calculator is;

D = 136

Determinant of the x-matrix from online determinant calculator is; Dx = 92

Determinant of the y-matrix from online determinant calculator is; Dy = 696

Determinant of the z-matrix from online determinant calculator is; Dz = 576

From crammers rule;

x = Dx/D = 92/136

y = Dy/D = 696/136

z = Dz/D = 576/136

Answer:

42(4 + r) is the answer if I'm reading that correctly.

Answer:

6 bouquet

Step-by-step explanation:

To obtain the greatest number of bouquet she could have ;

Obtain the greatest common factor of 18 and 24

Factors of 18 : 1 , 2, 3, 6, 9, 18

Factors of 24 : 1, 2, 3, 4, 6, 8, 12, 24

The greatest factor commo to both 18 and 24 is 6.

Hence, the greatest number of bouquet she could have is 6.

Answer: every 3 years

Step-by-step explanation:

Answer:

a=28

Step-by-step explanation:

a = 2b - c

a = 2(12) - (-4)

a = 24 + 4

a = 28

by the formula

a=2b-c

if b =12

so, a= 2*12-(-4)

a= 24+4

a=28

thank you

Answer:

Step-by-step explanation:

You should start with 10. The problem with 10 is that if you add 4 to it, the sum is less than 15, so no triangle will form.

A and B won't work either 4 + 15 is 19. A and B are both longer than 19 so no triangle will form.

The answer has to be C. 4 and 15 make 19. That's more than 17 so a triangle will be formed.

Answer:

[tex]\frac{1}{4k^3}[/tex]

Step-by-step explanation:

It's already in a form that only ha positive exponents.  Just to state it though you could rewrite it as [tex]k*(4k^{4})^{-1}[/tex] or [tex]k*4^{-1}*k^{-4}[/tex]  The question asks for positive exponents though so yu don't need to do that.

You also need to know [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] so in this case [tex]\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}[/tex]

so [tex]\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}[/tex]

Step-by-step explanation:

parallelogram

If a quadrilateral is a rhombus, then it is a parallelogram. If a parallelogram is a rhombus, then its diagonals are perpendicular. If a parallelogram is a rhombus, then each diagonal bisects a pair of opposite angles.
