The surface area of a regular square pyramid is 48cm². If the slant height is equal to the base-edge length, find the area of the base.

Answer:

12 possible outcomes

Step-by-step explanation:

If she's spinning them at the same time, this is how you do it:

There are 3 possible outcomes on the first spinner- Walk, Run, and Stop.

There are 4 outcomes on the second spinner- Red, Green, Blue, and Orange.

Since they're being spun at the same time, we need to consider all of the possible combinations, for example:

Walk & Red.

Walk & Green.

Walk & Blue.

Walk & Orange.

And so on.  Each outcome on the first gets multiplied by 4, since there are 4 sections on the 2nd spinner.  Same thing if you did it and switched- the 4 sections on the second spinner would each have 3 different outcomes.

In conclusion, you'd just multiply 3×4, and there you go.  Or, you can think of it as 4+4+4, if that's a little easier to understand.

The y-intercept of the line shown is -4.

Answer: y^2 -5 + y^2 -5 + 3y^2+7y+8 + 3y^2+7y+8

Step-by-step explanation: The order doesn't matter but... its just the sides added up together. Its a rectangle so the opposites are equal. You were given 2 sides and thats all you need, just repeat it. L plus l plus w plus w is there.

9514 1404 393

Answer:

  A. some values (x = 4)

  B. all values

  C. no values

Step-by-step explanation:

If you subtract the right-side expression from both sides of an equation, so you get something of the form ...

  f(x) = 0

Then there are three possibilities:

  f(x) is some function of x . . . . "some values" make it true*

  f(x) = 0 . . . . "all values" make it true; the equation is an identity

  f(x) = constant (non-zero) . . . . "no values" of x will make it true

___

A: 3x = x +8

  3x -(x +8) = 0

  2x -8 = 0 . . . . . . . . true for "some" values of x, namely, x = 4

__

B: 5x -(x +x +x +x +x) = 0

  0 = 0 . . . . . . . . . . . true for "all" values of x

__

C: 2(x +5) -(2x +5) = 0

  2x + 10 -2x -5 = 0

  5 = 0 . . . . . . . . . . . true for "no values" of x (always FALSE)

_____

* The possibility exists that the function f(x) does not have 0 in its range. In that case, there are no real solutions for the equation. For example |x|+1 = 0 has no solutions. For expressions linear in x, there will always be a solution.

Answer:

1. 14m, 11, 18m

2. 132 (rounded from 131.946)

3. Quadrilateral (duh it has 4 sides) and a rhombus?

Step-by-step explanation:

1 a unique triangle is a triangle with side lengths that are ALMOST exactly like a triangle. I used the pyragothem theory (a^2 + b^2 equals c^2) and this one was soo close to 18 (17.8)

2 the equation for the circumference of a circle is C=dpi. the radius is half of the diameter so 21 time 2 is 42 then multi[ply by pi.

3 is definitely already a quadrilateral (all of them have 4 sides) and the only shade i can think of that can have a 130 degrees for 2 angles would be a longgg rhombus ( or diamond)

Answer:

$12.50

Step-by-step explanation:

100%-20% -> $10

80% -> $10

100% -> [tex]\frac{100}{80}[/tex] × $10 = $12.50

Answer:

The original price was $12

Step-by-step explanation:

Let x be the number of households you mowed grass.

Let y be the number of households you shoveled snow.

From there, we know,

[tex]x + y = 22[/tex]

as equation 1.

next we also know,

[tex]150x + 225y = 3900[/tex]

as equation 2.

From here we know we can solve using simultaneous equations.

rearranging equation 1 with y the subject,

[tex]y = 22 - x[/tex]

Substitute this equation into equation 2.

[tex]150x + 225(22 - x) = 3900 \\ 150x + 4950 - 225x = 3900 \\ - 75x + 4950 = 3900 \\ - 75x = 3900 - 4950 \\ - 75x = - 1050 \\ x = - 1050 \div - 75 \\ = 14[/tex]

now substitute x = 14 into equation 1.

[tex]14 + y = 22 \\ y = 22 - 14 \\ = 8[/tex]

Therefore, you have mowed grass for 14 households and shovelled snow for 8 households.

mental math

Step-by-step explanation:

[tex]x: 77 = 7 : 11 \\x = \frac{77 \times 7}{11} = \\ = 49[/tex]

From the given equivalent ratio the value of x is the number 49.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The given equivalent ratios are x:77=7:11

"Two or more ratios that reflect the same relation or comparison of numbers are known as equivalent ratios," according to the definition of the equivalent ratio. The idea of corresponding fractions is comparable. The term "proportion" also refers to the equivalence of two ratios.

Here, x/77 = 7/11

Multiply both the numerator and denominator of the ratio 7/11 by 7, we get 49/77

Now, x/77 = 49/77

So, x=49

Therefore, the value of x is 49.

Answer:

Step-by-step explanation:

Simply we know this is an isosceles triangle meaning that:

The other angle is also 35.

With this information, we can say that as a triangle adds up to 180, we can put this in a formula:

x+35+35 = 180

x+70 = 180

x = 110

Its really easy

Answer:

D.

Step-by-step explanation:

So the question is asking which set of inequalities and given point represent the graph. The point it gives is (-3,1) on the graph. That already narrows your choices down to B and D. Now, the easiest way to see the answer is look at the y axis. In the equation y=mx+b, b is the value on the y axis. We see on the y axis that the equations pass through positive 1 and 2. D adds 1 and 2 the equations, so it would produce that graph.

Answer:

18 and 72

Step-by-step explanation:

4x+x=90

5x=90

divided by 5

x=18

for the first side, since you only have x, you put 18

for the second one, since 4x, 4(18)=72
