Answer:

The actual answer is 3.25

Step-by-step explanation:

I just took the test

the maximum number of hours that the repair person can work is 3.5 hours

Given :

Gloria doesn’t want to spend more than $100.

A service call will cost $35 and the labor will be an additional $20 per hour

Let 'h' be the maximum number of hours the repair can take.

Lets find out the total cost for 'h' hours

35+ additional 20 per hour

[tex]35+20h[/tex]

The total cost should not exceed 100

[tex]35+20h \leq 100\\20h \leq 100-35\\20h\leq 65\\Divide \; by \; 20\\h\leq 3.5[/tex]

So , the maximum number of hours that the repair person can work is 3.5 hours

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

Answer:

Below in bold.

Step-by-step explanation:

The 2 triangles are congruent and they are both isosceles.

So m < 3 = 54 degrees.  (isosceles triangle)

m < 2 = 54 degrees.      (congruent triangles)

m < 1 = 180 - 2(54)

= 180 - 108

= 72 degrees.                 (angles in a triangle sum to 180).

m < 4 = 72 degrees.       (congruent triangles),

Answer:

10 : 12 is equivalent to 5 : 6 and 20 : 24.

Step-by-step explanation:

You can divide and multiply the ratio by 2 to get an equivalent ratio.

The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given ratio, 10:12.

Divide numerator and denominator by 2

(10/2):(12/2) = 5:6.

Multiply the numerator and denominator by 2

(10×2);(12×2) = 20:24

Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".

Y intercept is -5

Step-by-step explanation:

It is negative five because it goes through the y axis at -5

Answer:

5. 3050ft³ (rounded to 3 s.f.)

6. 4190ft³(rounded to 3 s.f.)

7. 4600ft³(rounded to 3 s.f.)

Formulas (For easier reference):

Volume of a cone: pi×r²×[tex]\frac{h}{3}[/tex]

Volume of cylinder: pi×r²×h

Volume of a sphere: [tex]\frac{4}{3}[/tex]×pi×r³

Volume of a hemisphere: [tex]\frac{2}{3}[/tex]×pi×r³

Step-by-step explanation:

You can just apply the formulas to the question:

5. Volume of cone = pi×9²×[tex]\frac{(16-10)}{3}[/tex]

                               = 162pi

  Volume of cylinder = pi×9²×10

                                   = 810pi

Volume of figure = 162pi+810pi

                            = 972pi

                            = 3050ft³ (rounded to 3 s.f.)

6. Volume of sphere = [tex]\frac{4}{3}[/tex]×pi×10³

                                   = 1333[tex]\frac{1}{3}[/tex]pi

                                   = 4190ft³(rounded to 3 s.f.)

7. Volume of hemisphere = [tex]\frac{2}{3}[/tex]×pi×(26÷2)³

                                          = 1464[tex]\frac{2}{3}[/tex]pi

                                          = 4600ft³(rounded to 3 s.f.)

HAVE A NICE DAY!!!

Answer:

6x+8y = 3

Step-by-step explanation:

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8

so equation is

y = -3/4 x + 3/8

simplyfyig,

8y = -6x + 3

or, 6x+8y = 3

Step-by-step explanation:

you need to divide 8 by 2 which is 4

Answer:

(a)  [tex]3x^2 + 27y^2 + z^2 - 18xy + 6 \sqrt{3} yz -2 \sqrt{3} zx[/tex]

    this can be written as

     [tex](-x\sqrt{3})^2 + (y3\sqrt{3})^2 + (z)^2 +2 ( -x\sqrt{3} )( y3\sqrt{3}) + 2( y3\sqrt{3})(z) + 2(z)( -x\sqrt{3})[/tex]

    which is equivalent to

    [tex]a^2+ b^2 + c^2 + 2ab + 2bc + 2ac = (a+b+c)^2[/tex]

     [tex](-x\sqrt{3} + y3\sqrt{3} + z)^2 = (-x\sqrt{3} + y3\sqrt{3} + z)(-x\sqrt{3} + y3\sqrt{3} + z)[/tex]

(b)[tex]27 x^3 + 125y^3[/tex] = [tex](3x)^3 + (5y)^3[/tex]

which is same as [tex]a^3 + b^3 = (a+b)(a^2 +b^2 -ab)[/tex]

                    = [tex](3x + 5y)(9x^2 + 25y^2 -15xy)[/tex]

(c) [tex](2a - 3b + c )^2[/tex] = (2a -3b +c)(2a -3b+c)

(d) [tex]a^3 + b^3 + 125 c^3 - 15 a b c[/tex]

this is same as

[tex]a^3 + b^3 +c^3 - 3abc[/tex] = [tex](a+b+c)( a^2+b^2+c^2 -ab-bc-ac)[/tex]

     = [tex](a + b + 5c)(a^2+b^2 +25c^2 -ab -5bc -5ac)[/tex]

(e) [tex](x - 1/x y)^3[/tex] = [tex](x - 1/xy)(x - 1/xy)(x - 1/xy)[/tex]

(f) [tex]x^4 y^4 - x y64^4 = xy( x^3y^3 - 64^4) = xy( x^3y^3 - (256)^3) \\ = xy( xy - 256 )(x^2y^2 + 65536 + 256xy)[/tex]

(using the property of  [tex]a^3 -b^3 = (a-b)(a^2+b^2 +ab)[/tex] )

(g) [tex]8x^3 - (2x - y)^3 = (2x)^3 - (2x-y)^3 \\ = (2x - 2x + y)(4x^2 + (2x-y)^2 + 2x(2x-y))\\ = y(8x^2 + y^2 -6xy +4x)[/tex] using the same property above

(h)

[tex]a^6 -b^6 = (a^2)^3 - (b^2)^3 = (a^2-b^2)( a^4+b^4 +a^2b^2)\\ = (a-b)(a+b)( a^4+b^4 +a^2b^2)[/tex]

Answer:

[tex]-2t^2+ 6t -1 > 0[/tex]

Step-by-step explanation:

Function Modeling

The height h in feet of the stick threw by Tim is modeled by the function:

[tex]h = -16t^2+ 48t[/tex]

where t is the time in seconds.

It's required to write an inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet, i.e. h > 8.

Using the given model, we write the inequality:

[tex]-16t^2+ 48t > 8[/tex]

Dividing by 8

[tex]-2t^2+ 6t > 1[/tex]

Subtracting 1, we get the required inequality:

[tex]\mathbf{-2t^2+ 6t -1 > 0}[/tex]

Answer:

you want more than 8 feet so the answer would be -16t^2+48t>8

Step-by-step explanation:

h=-16t^2+48t

-16t62+48t>8

-16t^2+48t=8

divide both sides of the equal sighn by 8

-2t^2+6t=1

put the symbol back in

-2t^2+6t>1

substitute a random mumber for t

-2(5)^2+6(5)>1

-10^2+30>1

subtract 30 from both sides

100>-29

state is true so -16t62+48t>8 is the correct answer

Step-by-step explanation:

Add them in and try to solve for 7 and 6, for 8. I usually put all number on one side and all x on other side.

Answer:

26x47

Step-by-step explanation:

To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146

We simplify and get 6x - 10 = 146,

then divide both side by 6 and plus 10 both sides,

we will get

x = 26

Now we've found one of the length,

to find the other side we do 26 * 2 = 52, and subtract 52 from 146,

which would get 94, then we divide it by 2

94/2 = 47

The dimensions is 26x47
