Does an isosceles triangle have three congruent sides?

Answer:

g+r=15  and 2.00g+4.50r=37.50 are the two equations you need to use

Step-by-step explanation: IM NOT COMPLETLEY SURE THO

Answer: C

The total number of pounds of trail mix is 15. The pounds of granola added to the pounds raisins has to equal 15. So, one of the equations is g + r=15.

In total the cost of the granola and the cost of the raisins must be equal to $37.50. Since the granola costs $2 per pound and the raisins cost $4.50 per pound, 2g + 4.5r= 37.5.

Answer:

y=-7

Step-by-step explanation:

This is an expression, not an equation.  y is -7 for any value of x, so f drops out of the equation and it beomes an expression.

Answer:

Step-by-step explanation:

Volume of the cube is 27 cm^3

Since [tex]density = \dfrac{Mass}{Volume}[/tex]

density  = [tex]\dfrac{428 g}{27 cm^3} = 15.85 g/cm^3 > 1.7g/cm^3[/tex]

this will not float on the surface of the liquid.

Convert into kg/m^3

[tex]15.85 g/cm^3 = 15850 kg/m^3[/tex]

Answer:

[tex]7x^3(7x^2-9 )[/tex]

Step-by-step explanation:

To factor, you have to find the GCF of 49 and 63 and the GCF of [tex]x^{5}[/tex] and [tex]x^3[/tex]

Factor 49: 1,7, and 49

Factor 63: 1, 3, 7, 9, 21, 63

Factor [tex]x^{5}[/tex]: [tex]x*x*x*x*x[/tex]

Factor [tex]x^3[/tex]: [tex]x*x*x[/tex]

So the GCF of 49 and 63 is 7

The GCF of [tex]x^{5}[/tex] and [tex]x^{3}[/tex] is [tex]x^3[/tex]

We multiply 7 by [tex]x^{3}[/tex] to get [tex]7x^3[/tex]

So now we start to factor out the GCF of [tex]49x^5-63x^3[/tex]

[tex]7x^3(\frac{49x^5}{7x^3}+ \frac{63x^3}{7x^3} )[/tex]

[tex]\frac{49}{7} =7\\x^5-x^3=x^2[/tex]

[tex]\frac{63}{7} =9\\x^3-x^3=x^0[/tex] because [tex]x^{0}[/tex] can't be written as an exponent we don't write [tex]9x^0[/tex]

When we factor we get [tex]7x^3(7x^2-9 )[/tex]

the answer is 1.32503237E+22

The similar triangle relationship by the rays of the Sun and the shadow of

the Moon indicates that their distances to Earth are proportional.

Reasons:

The diameter of the Sun = 1,391,000 km

The diameter of the Moon = 3,475 km

The distance between the Earth and the Moon = 149,60,000 km

Required:

The distance that the Moon can be from Earth, such that the Moon appear to be the same size as the Sun.

Solution:

The vertex angle formed by the Moon and the Sun at the Earth are the

same, assuming the Moon and the Sun are in the same line, we have;

Considering the diameters of the Sun and the Moon as parallel lines, we have;

The base angles formed at the Sun and the Moon are equal

Therefore, the shadows of the Sun and the Moon form similar triangles with the Earth.

Using the relationship similar triangles, we have;

[tex]\displaystyle \frac{Disatance \ of \ the \ Sun \ from \ the \ Earth}{Diameter \ of \ the \ Sun} =\mathbf{ \frac{Distance \ of \ the \ Moon \ from \ the \ Earth}{Diameter \ of \ the \ Moon}}[/tex]

Which gives;

[tex]\displaystyle \frac{149,600,000}{1,391,000} = \mathbf{\frac{Distance \ from \ the \ Moon \ to \ the \ Earth, \ d }{3,475}}[/tex]

[tex]\displaystyle The \ distance \ from \ Moon \ to \ Earth, \ d = \displaystyle \frac{149,600,000}{1,391,000} \times 3,475 \approx 373,731.13[/tex]

The distance the Moon have to be from Earth for the Moon to appear the same as the Sun, d ≈ 373,731.13 km.

Answer:

(a) P = 32.5 feet

(b) P = 108-2x feet

Step-by-step explanation:

Note: Perimeter is the total distance around the border of a shape.

(a)

P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)

[tex]27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}[/tex] = 2.25feet

P = 14'+2.25'+14'+2.25'

P = 32.5' = 32.5 feet

(b)

P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.

P = 108' -2x'

P = 108-2x feet

Note: there is not enough information to determine the vaule of x from the problem.

Answer:

Step-by-step explanation:

Since the shape is congruent with the other sides it's the same.

1,3,5,7 = 126°

2,4,6,8 = 54°

Here your go m'dear

Given, ∠3 = 126°.

∠3 =∠1 = 126° (vertically opp. angles)

∠3 =∠5 = 126° (alternate interior angles)

∠3 =∠7 = 126° (corresponding angles)

Now, ∠2 = 180° - 126° = 54° (linear pair/supplementary angles)

∠2 = ∠4 = 54° (vertically opp. angles)

∠2 = ∠8 = 54° (alternate interior angles)

∠8 = ∠6 = 54° (vertically opp. angles)

Answer:

44.4 or 14.9 depending on which volume is being stated

Step-by-step explanation:

Not sure if it is the smaller cube or the bigger cube that is 3250 cm^3 so ill do both.

LARGER CUBE IS 3250 cm^3

first find the side length by finding the cube root of 3250, which is about 14.8, then divide that by 3 to find the side length of the smaller cube, which is about 4.9.

SMALLER CUBE IS 3250 cm^3

first find the side length by finding the cube root of 3250, which is about 14.8, then multiply that by 3 to find the side length of the larger cube, which is about 44.4.

Answer:

y = -3x + 11

Step-by-step explanation:

To find the equation of the line we would plug in the given info into the point slope equation:

[tex]y-y_{1} =m(x - x_{1} )[/tex]

In this case (x1, y1) is (4, -1) and m is -3:

y - (-1) = -3(x - 4)

We can simplify as follows:

y + 1 = -3x + 12

y = -3x + 11

ALL of the following expressions are NOT equivalent to 64^5t^2+3t

Step-By-Step Explanation:

Khan Academy

To determine whether each expression is equivalent to [tex]64^5t^2 + 3t[/tex], we will simplify each expression by evaluating the calculations.

Expression 1:   [tex]64^5t^2 + 3t[/tex]

Expression 2:  [tex](4^3)^5t^2 + 3t = 4^(3*5)t^2 + 3t = 4^15t^2 + 3t[/tex]  

Expression  3:  [tex](8^2)^5t^2 + 3t = 8^(2*5)t^2 + 3t = 8^10t^2 + 3t[/tex]  

Expression 4:   [tex](2^6)^5t^2 + 3t = 2^(6*5)t^2 + 3t = 2^30t^2 + 3t[/tex]  

Expression 5:   [tex](8^8)^3t^2 + 3t = 8^(8*3)t^2 + 3t = 8^24t^2 + 3t[/tex]  

Expression 6:   [tex]64^5t^2 + t + 2t = 64^5t^2 + 3t[/tex]

After evaluating each expression, we can see that all the expressions are equivalent to [tex]64^5t^2 + 3t[/tex]. The calculations show that regardless of the specific values used, the expressions simplify to the same result. Therefore, it can be concluded that all six expressions are equivalent to [tex]64^5t^2 + 3t.[/tex]

Answer:

The first choice:

x: -5, -4, -3, -2, -1

y: -5, -3,  -1,   1,  3

Step-by-step explanation:

If we apply the equation here...

y = 2x + 5

(Let's use -1 for example)

y = 2(-1) + 5 --> y = -2+5, which gives us 3

On the table, it says that the y is 3, so it proves that it is correct

If you apply the equation for all of the x's, it'll give you the y's for the first choice. This doesn't apply to the rest of the tables, so the first table is the correct choice

The values are satisfied by

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given:

Y= 2X +5

let us put the value for X

X= 0

Y = 5

and, X=1

Y = 2 + 5 = 7

and, X= 2

Y= 4 + 5 = 9

and, X=3

Y = 6 + 5 = 11

and, X= 5

Y = 10 + 5= 15

and, X= -1

Y= -2 + 5 = 3

Hence, these values are satisfied by

x      y

-5    -5
