Answer:

  100

Step-by-step explanation:

A root is equivalent to a fractional power. A square root is a 1/2 power. A cube root is a 1/3 power. The index of the root is the denominator of the fraction.

Of course the usual rules of exponents apply in evaluating an expression.

  (a^b)^c = a^(bc)

__

Your expression can be simplified as follows.

  [tex]\displaystyle\sqrt[3]{1000^2}=(1000^2)^{\frac{1}{3}}=1000^{\frac{2}{3}}=(10^3)^{\frac{2}{3}}=10^2=\boxed{100}[/tex]

It can also be simplified another way:

  [tex]\displaystyle\sqrt[3]{1000^2}=\sqrt[3]{(10^3)^2}=\sqrt[3]{(10^2)^3}=10^2=100[/tex]

With reference angle E

hypotenuse (h) = 89

base (b) = 39

cosine angle E

= b /h

= 39/89

Answer:

8 and 36

Step-by-step explanation:

let the daughter's age be x then father is x + 28

In 6 years their ages are

x + 6 and x + 28 + 6 = x + 34

Father is 3 times her age , then equation is

x + 34 = 3(x + 6) ← distribute

x + 34 = 3x + 18 ( subtract x from both sides )

34 = 2x + 18 ( subtract 18 from both sides )

16 = 2x ( divide both sides by 2 )

8 = x

Daughter's age is 8 and father's age is 8 + 28 = 36

Answer:

80 + 15x ≤ 300

Step-by-step explanation:

max amount = $300

already spent = $80

$300 - 80 = $220

shirts = $15 each

80 + 15x ≤ 300

$80 that is already spent + $15x ≤ $300 maximum

x = number of shirts

Answer:

x = 3/4

Step-by-step explanation:

Answer:

x = 3/4

Step-by-step explanation:

Find the LCD of the fractions.  Multiplying the denominators 3 and 4 together, we get LCD = 12.  

Rewriting the mixed numbers, we get

3 2/3 = 3 8/12 and 3 1/4 = 3 3/12

So the original equation becomes

(3 8/12)x + 3 3/12 = 6

We must now combine like terms:  subtract 3 3/12 from both sides of this equation, obtaining:

(3 8/12)x = 6 - 3 3/12, or

(3 8/12)x = 2 9/12.  Converting the mixed numbers into improper fractions, we get:

(44/12)x = 33/12.  Multiplying both sides by 12 yields 44x = 33

and so x = 33/44 = 3/4

x = 3/4

Alternatively, convert the original mixed numbers into improper fractions right away.  Then the original   3 2/3 x+3 1/4=6

becomes (11/3)x + 13/4 = 72/12, or

                 (44/12)x + 39/12 = 72/12

Multiplying all three terms by 12 yields:

44x + 39 = 72, which simplifies to 44x = 33, or x = 3/4

Step-by-step explanation:

Speed  = 93km /h  and  72km/h

Answer: The taxi went a distance of 554.7km

Step-by-step explanation:

Speed  = Distance / Time

Distance covered in the first trip = Speed x Time

Time = 1 hour 54 min =1+0.9 hours  =1.9hours

=93km / h x 1.9 hours =176.7km

Distance covered in the second  trip = Speed x Time

Time = 5 hours 15min = 5+0.25hours  =5.25hours

=72km / h x 5.25hours =378 km

Total distance =176.7km+378 km

=554.7km

Answer:

m= −2 /7

Step-by-step explanation:

Let's solve your equation step-by-step.

6m+1m=−2

Step 1: Simplify both sides of the equation.

6m+1m=−2

6m+m=−2

(6m+m)=−2(Combine Like Terms)

7m=−2

7m=−2

Step 2: Divide both sides by 7.

7m /7 = −2 /7

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

[tex] {x }^{2} - 3x + 4(x - 3)[/tex]

2) Expand by distributing terms.

[tex] {x}^{2} - 3x + 4x - 12[/tex]

3) Collect like terms.

[tex] {x}^{2} + ( - 3x + 4x) - 12[/tex]

4) Simplify.

[tex] {x}^{2} + x - 12[/tex]

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Answer:

C. 64

Hope that helps you

The value of the angle x is calculated as: ∠x = 64

Let the intersect of line SV and RT be Y

Sides RTU forms a triangle, and the sum of the interior angles of a triangle is 180.

Since RT = TU, ∠TRU  = ∠TUR = z

114 + z + z = 180

114 + 2z = 180

2z = 180 - 114

2z = 66

z = 66/2

z = 33

Line STU is a straight line and the angle of a straight line is 180. Thus:

114 + ∠STR  = 180

∠STR = 180 - 114

∠STR = 66

Also, sides SYT is forms a triangle and the sum of all interior angles of a triangle is 180. Thus:

66 + 31 + ∠SYT = 180

97 + ∠SYT = 180

∠SYT = 180 - 97

∠SYT = 83

But ∠SYT = angle RYV = 83

sides RYV form a triangle and the sum of all interior angles of a triangle is 180

33 + 83 + ∠x = 180

116 +  ∠x = 180

∠x = 180 - 116

∠x = 64

Answer:

angle x = 28 degrees

Step-by-step explanation:

Because of vertical angles, angle IAK and angle BAC are equal, and angle GCJ and angle ACB are also equal due to vertical angles

Since KL is perpendicular to FG, angle ABC is 90 degrees

ABC is a right triangle and acute angles in a right triangle are equal to 90 degrees

This means that angle BAC + angle ACB = 90 degrees

angle BAC = 62 degrees and angle ACB = x degrees

62 + x = 90

x = 28 degrees
