Answer:

64 cm^2

Step-by-step explanation:

I assume the side of the base measures 4 cm, and the height of each triangular side (the slant height) is 6 cm.

SA = s^2 + 4 * bh/2

SA = (4 cm)^2 + 2(4 cm)(6 cm)

SA = 16 cm^2 + 48 cm^2

SA = 64 cm^2

Answer:

Step-by-step explanation:

Multiply 255.38 times 0.20 (20%). You get 51.076. Subtract 51.076 from 255.38. You get 204.304. Multiply this by 0.11 (11%). You get 22.47344. Add this to 204.304. You end with 226.77744. Divide this by 4. You get 56.69436 or $56.69 a piece.

Triangles can be named using the measure of their angles; triangle ABC is an obtuse triangle

The angles are given as: 20, 50 and 110

When one of the angles of a triangle is greater than 90 degrees, then such triangle is an obtuse triangle

110 degrees is greater than 90 degrees.

This means that:

Triangle ABC is an obtuse triangle

Hence, the true option is (c)

Answer:

3/5

Step-by-step explanation:

First one   18^2 - 4(-1)(81)  > 0    so no repeated root

Second one     (-3)^2  - 4(3) (-168)  >  0    so no repeated root

Third one   (-4) - (4) (1) (-4)  > 0      so no repeated root

Fourth one  (-30)^2  - 4(25) (9)   =  900 - 100(9)  =  0      repeated root

Note  this factors  as  (5x - 3)^2  

(5x - 3)^2  = 0     take both roots

5x - 3  = 0

5x  = 3

x  =  3/5   = repeated root

The quadratic expression \(25x^{2} -30x+9\) has repeated root and the repeated root is 3/5

Let, \(ax^{2} +bx+c=0\) is a quadratic.

Then the expression (\(b^{2}-4ac\)) is called the discriminant of the quadratic.

If  \(b^{2}-4ac\) = 0 then we can say that the quadratic has a repeated real root.

The discriminant of \(-x^{2} +18x+81\) is,

\(b^{2}-4ac\) = \(18^{2}-4(-1)(81)\) = 324+324=648 > 0

So, This quadratic has no repeated root.

The discriminant of \(3x^{2} -3x-168\) is,

\(b^{2}-4ac\) = \((-3)^{2}-4(3)(-168)\) = 9+2016 = 2025 > 0

So, This quadratic has no repeated root.

The discriminant of \(x^{2} -4x-4\) is,

\(b^{2}-4ac\) = \((-4)^{2}-4(1)(-4)\) = 16+16 = 32 > 0

So, This quadratic has no repeated root.

The discriminant of \(25x^{2} -30x+9\) is,

\(b^{2}-4ac\) = \((-30)^{2} -4(25)(9)\) = 900-900 = 0

So, This quadratic has repeated root.

The discriminant of \(x^{2} -14x+24\) is,

\(b^{2}-4ac\) = \((-14)^{2}-4(1)(24)\) = 196-96 = 100 > 0

So, This quadratic has no repeated root.

The equation \(25x^{2} -30x+9\) = 0 has repeated root.

Simplifying the equation we get,

\(25x^{2} -30x+9\) = 0

⇒ \((5x)^{2}-2(5x)(3)+3^{2}\) = 0

⇒ \((5x-3)^{2}\) = 0

⇒ 5x-3 = 0

⇒ 5x = 3

⇒ x = 3/5

The repeated root is 3/5.

Answer:

$6.88 B.

Step-by-step explanation:

The answer is $6.88. (Here's why )

Sales tax rate = 7.4 %

price of shoes = $ 93

Tax paid for a pair of shoes = 7.4 % x $ 93

=7.4/100 x 93

= 0.074 x 93

= 6.882

Answer:

Step-by-step explanation:

Let the tenth digit is x and units digit is y.

We have the following equations:

Simplify the second equation:

Solve by substitution:

Find y:

The number is 27

Here the equations are if the digits be a and b

3(a+b)=10a+b

Equate both

And

The number is 27

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

26-ounce package

Step-by-step explanation:

Divide the cost for a 6-ounce and a 15-ounce package separately by the number of ounces listed above.  1 ounce for a 6-ounce package costs around $0.36 and 1 ounce for a 15-ounce package cost around $0.37.  If we put the 26-ounce package in place, then each ounce cost $0.35.  We want to buy the one that is the cheapest out of all of them and since the 26-ounce package cost more cheaper than the other packages, then you should buy the 26-ounce package since it is the best deal.
