Answer:

  yes, the triangles are congruent -- by the SAS congruence postulate

Step-by-step explanation:

Two sides and the angle between them are marked congruent, so the Side-Angle-Side (SAS) congruence postulate applies.

The two triangles are SAS congruent.

Answer:

5,240 literate

1310 illiterate

Step-by-step explanation:

-ratio of literate : illiterate is 1:4

-add the numbers in the ratio (4+1=5)

-divide total population by 5 (6,550/5= 1,310)

-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)

-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

Answer:

I think its 15^-7

Step-by-step explanation:

you can forget about the one and just look at the 15 and 7 which you get 15^-7

The fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= (1/15)⁷

As we know, from the definition of the integer exponent;  integer exponents are exponents that should be integers. It may be a positive or negative number.

After using the properties of the integer exponent:

= (15⁻¹)⁷

= 15⁻⁷

Thus, the fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

Answer:

28

Step-by-step explanation:

28 times 2 = 56

28 times 1 = 28

56 + 28 = 84

Step-by-step explanation:

First expression = 3y

second expression = 3 * 2 x

LCM = 3 * 2x * y = 6xy

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Where is the question?

Answer: There are 375 star stickers and 125 heart stickers.

There are 500 stickers with 20 stickers per sheet; 500/20 = 25 sheets of stickers.

25% of each sheet is hearts; 25/100(20) = 5 heart stickers per sheet.  5(25) = 125 total heart stickers.

20 stickers per sheet - 5 heart stickers per sheet = 15 star stickers per sheet.  15(25) = 375 total star stickers.

Answer:

D

Step-by-step explanation:

What we have to do is to find the arc tan

x/2 = arc tan (-1)

tan is negative on the 4th and second quadrant

arc tan (-1) = 135 or 315

pi is 180 degrees

so we have;

135 is 3 pi/4

multiplied by the 2

= 6 pi/4 which is 3 pi/2

315 is 7 pi/4 which is same as 7 pi/2 when we multiply by 2

Answer: You'll have a quadrilateral with the following points

A diagram is posted below.

===================================================

Explanation:

The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that

I started at the lower right corner and worked my way clockwise.

----------------

Let's shift the line y = x-2 up two units so that it moves to y = x

We'll need to shift every point of the quadrilateral up two units as well.

So we have these new point locations after the shifting has occurred.

----------------

Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.

So we can say [tex](x,y) \to (y,x)[/tex]

A point like (-3, 5) moves to (5, -3)

We have these new locations

----------------

The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.

Doing this leads to these locations

Check out the diagram below.

Answer:

£208

Step-by-step explanation:

Given:

Height of solid box (h) = 20 cm

Width (w) = 80 cm

Length (l) = 10 cm

Cost of paint = £0.04 per cm²

Required:

Cost of painting the box

Solution:

✔️First, find the surface area of the box

Surface area = 2(l*w + l*h + w*h)

S.A = 2(10*80 + 10*20 + 80*20)

S.A = 2(800 + 200 + 1,600)

S.A = 2(2,600)

S.A = 5,200 cm²

✔️Find the cost of painting 5,200 cm² surface area of the box.

Cost of pianting 1 cm² = £0.04

Cost of painting 5,200 cm² = 5,200 × 0.04

Cost of painting the box = £208

Answer:

19

Step-by-step explanation:

Number of crackers that can be fit into the box = volume of the box / volume of crackers

Volume = length x width x height

volume of the box = 8 cm x 2.4 cm x 60 cm = 1152 cm^3

Volume of the crackers = 3cm x 4 cm x 5cm = 60cm^3

1152/60 = 19.2

Rounding 19.2 to the nearest whole number gives 19

Answer:

i don't understand what your asking, but i hope this helps

Step-by-step explanation:

the process of ascertaining the variable value that makes the equation true is called 'solving' the equation. An equation is a verbalization that two quantities are equipollent. For exp/example:. x + 1 = 4 betoken that when we integrate 1 to the unknown value, 'x', the answer is equipollent to 4

Answer: The length of the fence will be 150 feet

Step-by-step explanation:

The question is asking you to find the hypotenuse of a rectangle with a length of 120 feet and a width of 90 feet. To find the hypotenuse we will need to use the formula   a^2 + b^2 = c^2

120 feet will be a

90 feet will be for b  

this is because a and b are the two legs of the rectangle.

120^2 + 90^2 = c^2

14400 + 8100 = c^2

22500 = c^2

   c =√22500

 c= 150

Answer:

x = 3, y = 7

Step-by-step explanation:

Since we already have y's value, we can plug y into the bottom equation to get 3(5x - 8) = x + 18. We can distribute 3 into 5x and 8 to get 15x - 24 = x + 18. We can now subtract x from the both sides to get all terms on one side to get 14x - 24 = 18. We can now add 24 to both sides to get 42. We can now divide both sides of the equation by 14 to get x = 3. We can plug x into the top equation to get y = 5(3) - 8. We can multiply 5 and 3 together to get y = 15 - 8. We can simplify and subtract to get y = 7. Our final answer is (3, 7)

Answer:

Step-by-step explanation:

Length (L)= 2x - 3 cm

Breadth (b) = x + 7 cm

Area of the rectangle

= L * b

= ( 2x - 3)(x+ 7)

= 2x(x + 7) - 3(x + 7)

= 2x² + 14x  - 3x - 21

=( 2x² + 11x - 21) cm²

Answer:

[tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Step-by-step explanation:

Area of a rectangle = Length × Width

= (2x-3)(x+7)

Multiply 2x with x, 2x with +7, -3 with x and -3 with +7

= [tex]2x^{2}[/tex] + 14x - 3x - 21

= [tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Answer:

Infinite

Step-by-step explanation:

We know that in a triangle the sum of all the interior angles must be 180°.

The given angles 50º, 90º and 40º

The sum of the angles 50º+ 90º + 40º= 180°

Thus, a triangle is possible with the given measurement.,

Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.

Similarly, all the triangles with the same measurements of the angles must be similar.

Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

Answer:

d = 2√29 units

Step-by-step explanation:

M(-3, 1)and N(7, -3)​

To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the values.

d = √[(7 - (-3))² + (-3 - 1)²]

Simplify the parentheses.

d = √[(7 + 3)² + (-4)²]

d = √[(10)² + (-4)²]

Simplify the exponents

d = √[(100 + 16)]

Simplify the parentheses by adding.

d = √[116]

Simplify the brackets with the square root.

d = 2√29 units

Hope this helps!
