What is the measure of ∠R to the nearest degree?

31°

53°

58°

80°

Answer:

2

Step-by-step explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

= ( 8-2)/(9-6)

 =6/3

  =2

Answer: The slope of the linear function is 2.

Step-by-step explanation:

We can use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] to find the slope

[tex]\frac{8-2}{9-6} \\\frac{6}{3} \\2[/tex]

The slope is 2.

Answer:

36 green apples

Step-by-step explanation:

Number of red apples = percentage of red apples x total number of apples in the box

percentage of red apples = 100 - 40 = 60%

0.6  x 60 = 36

Explanation:

If the circumference is r = 12 cm, then the diameter is double that at d = 2*r = 2*12 = 24 cm.

This then leads to the circumference of C = pi*d = pi*24 = 24pi

This is exact in terms of pi. Replace pi with something like 3.14 to find its approximate value. The circumference is the distance around the circle's edge, aka perimeter.

Answer:

a) 22 batches

c) 7.3 batches

Step-by-step explanation:

a) It takes 0.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.50 cups of sugar. How many batches of cookies can I make?

0.25 cup = 1 batch

5.5 cup = x

Cross Multiply

0.25 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.25 cup

x = 22

I can make 22 batches of chocolate chip cookies. You may use the scratchpad to show your work.

(b) Lemon Cookies It takes 0.75 cups of sugar to make a batch of lemon cookies. I have 5.5 cups of sugar. How many batches can I make?

0.75 cup = 1 batch

5.5 cup = x

Cross Multiply

0.75 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.75 cup

x = 7.3 batches

I can make 7.3 batches of lemon cookies. You may use the scratchpad to show your work.

Answer:

a reflection across line m

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".

Steps of Transformation

Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.

Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.

Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

Answer:

40

Step-by-step explanation:

Total number of toffees = 975

Total number of children = 23

Estimate the numbers of toffees that each child will get in nearest tens.

Number of toffees each child get = Total number of toffees / Total number of children

= 975 / 23

= 42.391304347826

Approximately,

Number of toffees each child get = 40 to the nearest tens

Answer:

64 × pi m²

Step-by-step explanation:

the formulas needed for the surface area of a cone are :

base area plus the "mantle", the lateral "wall" around it.

the base area is a circle.

so, that formula is Ac = pi×r²

the "wall" formula is Aw = pi×r×s

r = radius

s = slant height = 12

the formula for the surface area of a sphere is

As = 4×pi×r²

we know now, that both surface areas are the same, and also the radius is the same for both objects.

Ac + Aw = As

pi×r² + 12×pi×r = 4×pi×r²

=>

12×pi×r = 3×pi×r²

12×pi = 3×pi×r

12 = 3×r

r = 4 m

now, we only need to use this value of r in our formulas for surface areas, like for the sphere :

4×pi×r² = 4×pi×4² = 4³×pi = 64×pi

Answer:

every parallelogram is a square? False

every rectangle with four congruent sides is a square? True

every rectangle is a quadrilateral? True

every quadrilateral is a rectangle?​ False

Step-by-step explanation:

every parallelogram is a square?

A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.

every rectangle with four congruent sides is a square?

Square require 4 congruent sides and 4 right angles. Rectangles already have  4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.

every rectangle is a quadrilateral?

A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.

every quadrilateral is a rectangle?​

A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

Answer:

a= 4. b=19. n=4. d= b-a/n+1= (19-4)/(4+1)= 15/5=3. Hence, d=3.

Do you also want an explanation?

Answer:

7  10  13   16

Step-by-step explanation:

a1 = 4

a6 = 19

n = 6

d = ?

a6  = a1 + (n - 1)d        

19 = 4 + (6 - 1)*d

19 - 4 = 5*d

15 = 5d

d = 15/5

d = 3

So the sequence is

4,7,10,13,16,19

Answer:

D - 192

Step-by-step explanation:

So the solve this, lets use the formula for area of a triangle:

b*h / 2 = A

b is the base, h is the height.

In this case, our base is 32, and our height is unknown.

To find it we must use pythagreons theorm:

[tex]a^2+b^2=C^2[/tex]

a is half of the base in this case, since tecnically this iscoceles traingle(2 same sides) cut in half is 2 right triangles.

32/2 = 16

b is the unknown, and C is the hypotenuse(longest length) which is 20:

[tex]16^2+b^2=20^2[/tex]

[tex]256*b^2=400[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

So we know b, whihc is our height, is 12.

Plugging this in:

32*12 / 2 = A

384 / 2 = A

192 = A

So the area of the triangle is 192.

Hope this helps!

Answer:

D: 192 square ft

Step-by-step explanation:

We are given all 3 side lengths of the triangle, and we notice that 2 of the sides are congruent (the 2 sides that are 20 ft). Therefore, we can safley say that this triangle is isosceles. What this tells us is that the height bisects the base. This is important because we can say that the base for each of the right triangles created by the height is 16. From there, we can say that h = 12 because 20 and 16 are basically 4 and 5 multiplied by 4, which means that the side lengths form a scaled-up version of the Pythagorean Triple 3-4-5. Now, just calculate the area by doing [tex]\frac{1}{2}*32*12[/tex] (basically just half * base * height), which gives us 192 [tex]ft^{2}[/tex]. Hope this helps! Feel free to reach out if you have any further questions.

Explanation:

Both figures shown in A and B are triangular pyramids. The base is a triangle, and the lateral sides are also triangles. Another example would be rectangular pyramids where the base is a rectangle, and the lateral sides are triangles.

Choice C is ruled out because cones aren't considered pyramids.

Choice D is a combination of a rectangular prism, and a rectangular pyramid stacked on top, so it's not purely a pyramid only. We can rule out choice D.

the equation of the circle centered at (-3, – 10)

=> (x+3)²+(y+10)²=2²

<=> x²+6x+9+y²+20y+100=4

x²+y²+6x+20y+105=0

Let's see
