Answer:

A. ST = RU

Step-by-step explanation:

Quadrilaterals are four sided figures. Examples are: square, rectangle, trapezium, parallelogram etc. A parallelogram is a quadrilateral that has equal opposite and parallel sides.

This implies that in the given question since RS || TU, then;

RS = TU = 6

So that for RSTU to be a parallelogram,

ST = RU

Thus, the appropriate option to the question is A.

Answer:

hello again

Step-by-step explanation:

the radius of the circle is 6mm

for having the circumference we need diameter

for having diameter we should multiply in 2

so:

[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]

i hope this is the answer

Answer:

$57.50

Step-by-step explanation:

find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

Answer:

The tip of the shadow is moving at 4.8 ft per sec when the question is:

"A street light is at the top of a 16 ft tall pole. A woman 6 ft tall walks away from the pole with a speed of 8 ft/sec along a straight path. How fast is the tip of her shadow moving when she is 35 ft from the base of the pole?"

Answer:

A and B are correct

Step-by-step explanation:

if x:y is 1:3 then x is 1 and y is 3

1/3 of 3 is 1 so A is correct

3/4(1+3) is 3 so B is correct

But

1/4 × 3 is not 1 so C is not correct

3/4 ×1 is not 3 so D isn't correct

Answer:

1. x=9

2. x=88

3. x=-15.7

4. x=-6

5. x=-20

6. x=10

7. x=-12

8. x=25

Hope this helps

Answer:

For Area = l × w

= 18 × 15

= 270 cm2

For Perimeter = 18 + 15 + 18 + 15

= 66cm

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

[tex]\frac{L}{W}=\frac{5}{3}[/tex]

Where:

Now, we know that each dimension is reduced by x inches, it means:

[tex]L=18-x[/tex]

[tex]W=12-x[/tex]

Then, we will have:

[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]

Finally, we just need to solve it for x.  

[tex]3(18-x)=5(12-x)[/tex]

[tex]5x-3x=60-54[/tex]

[tex]2x=6[/tex]

[tex]x=3[/tex]

Therefore, the value of x = 3.

I hope it helps you!

Answer:

4xy/z^2

Step-by-step explanation:

Here, we want to make a division

We have this as;

24xy^2/6yz^2

that will be

24/6 * x * y^2/y * 1/z^2

= 4 * x * y * 1/z^2 = 4xy/z^2

Answer:

The price increased by 64.5, which makes a total of 279.5

Step-by-step explanation:

215*0.30 = 64.5

215 + 64.5 = 279.5

0.30 = 30% of 100

When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

Answer:

10 ft.

Step-by-step explanation:

V = Bh where B = area of the base, which is a circle in your problem.

So, B = [tex]\pi r^{2}[/tex]

225π = π[tex]r^{2}[/tex](9)

[tex]r^{2}[/tex] = 25

r = 5 ft

diameter = 2r = 10 ft.

Answer:

Good luck :)

Answer:

74.8

Step-by-step explanation:

Cos M = adjacent/hypotenuse = 26/99

M = [tex]Cos^{-1}[/tex](26/99)

M = 74.774 ≅ 74.8

​

Answer:

74.8 is the correct answer

Answer:

The range here is 85

Step-by-step explanation:

Here, we want to calculate the range of the data

Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset

From the given data points, the highest value is 189, while the lowest value is 104

So the range is the difference between the two which is;

189-104 = 85

Answer:

35 degrees

Step-by-step explanation:

we add all answers 105+105+115 and get 325 so we subtract 360 from 325 bc 360 is the maximum angle a quadrilateral can be.

Answer:

let missing no.be x

x+105+105+115=360(sum of angle of kite is 360)

x=360-325=35

therefore missing Angle is 35°

Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)         3x -  8y   =  24   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

Answer:

- 5x + y =-3    ......1

3x -8y = 24.........2

eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3

-40 x +8 y =-24 ...........3

3 x   - 8y  = 24     ......... 2

·································

-37 x +0 = 0

··························

x =0

put x = 0 in equation 2

3 x -8 y =24

3×0 -8 y = 24

0 -8 y=24

-y =24÷8

-y =3

y = -3

ans ;

x = 0

y = -3
