Answer:

h = 5/2 or 2 1/2

Step-by-step explanation:

The formula to calculate the area of a parallelogram is given as Area of parallelogram = base × height square units

so A = bh

11 1/4 = 4 1/2(h)

h = 11 1/4/4 1/2

h = (45/4)/(9/2)

h = 5/2 = 2 1/2

Answer:

C. 1 in 2

Step-by-step explanation:

even numbers are 0, 2, 4, 6 etc.
the even numbers in a number cube are
2, 4, 6
so there is 3 possible results
all the numbers in the number cube are 6 numbers
so it is 3/6 times we can get an even number
by simplifying 3/6 (dividing by 3) we get 1/2

Answer:

x=40

Step-by-step explanation:

Looking at this problem, we can see that 3x+9=129

Subtract 9 on both sides:

3x=120

Divide by 3 on both sides:

x=40

Answer:

our fraction is 33.333333333333/100, which means that 20/60 as a percentage is 33.3333%.

The slope of the linear equation is 20 and the y-intercept is 150

Slope measures how steep a straight line is. It is described as rise over run.

The slope of the linear equation can be found as follows;

He opens the account with $150 and he plans to save $20 each week. Therefore,

let

x = number of weeks

Therefore,

where

y = amount in his account after x number of weeks.

Using the slope intercept equation,

where

m = slope

c = y-intercept

Therefore, the slope of the linear equation is 20 and the y-intercept is 150

Largest possible value of b is:

75

we are given that:

ab=1200

where a is an integer and b is an odd integer.

we know that product of odd numbers is always odd.

Now, 1200= 12×100

               = 2×6×10×10

              =2×2×3×2×5×2×5

It cannot be factorized further

Now, considering the product of all odd numbers

=3×5×5

=75

Now, if we multiply any other remaining number from the factorization of 1200, we will get a even number

Hence, The largest possible value of b is:

75

Answer:

x=50

Step-by-step explanation:

Since Line AB and Line CD are parallel, Angle AFG is supplementary to Angle CGF. So then x+3x-20=180. Then you just solve for x.

Combine like terms-> 4x-20=180

Add 20 to both sides-> 4x=200

Divide both sides by 4-> x=50

7+8+10=25cm is the possibile perimeter of this

triangle.

Answer:

y = root under 24 (evaluate it if necessary)

or y = 2 root 6

Step-by-step explanation:

Let the reference angle be x

for the triangle in left,

b = 6-4 = 2

Now,

taking x as refrence angle,

cosx = b/h

or, cosx = 2/h

again,

for the bigger triangle,

taking x as reference angle,

cosx = b/h

or, cosx = b/6

As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,

Let's suppose its a

so, cosx = a/6 = 2/a

now,

a/6 = 2/a

or, a² = 12

now,

for bigger triangle, using pythagoras theorem,

h² = p²+b²

or, 6² = y² + a²

or, 36 = y² + 12

or, y² = 24

so, y = root under 24

Answer:

No

Step-by-step explanation:

Exponents are only added when polynomials are multiplied and only applies to like terms. You add the coefficients of the like terms instead.

For example:

[tex](x^2+3x+6)+(2x^2-4x+1)=(1+2)x^2-(3-4)x+(6+1)=3x^2-x+7[/tex]

Answer:

no

Step-by-step explanation:

The exponents are added when the the same coefficient is multiplied:

[tex]x^2(x^3) = x^5[/tex]

If you think about it:

x^2 = x * x    and     x^3 = x * x * x

so you get:

(x^2)(x^3) = x * x * x * x * x = x^5

But, when adding x's of the same power, you add a coefficient:

[tex]x^2 + x^2 = 2x^2[/tex], not [tex]x^2 + x^2 = x^4[/tex]

Always remember to only add exponents when the coefficient/variable is multiplied, not added.

And, when an exponent is put to an exponent, multiply them:

[tex](x^3)^3 = x^3^(^3^) = x^9[/tex]

Answer:

6/7

Step-by-step explanation:

Your first step will be to find the slope of Line C. Using the slope formula of [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex], the slope of Line C is [tex]\frac{7-14}{7-1} = \frac{-7}{6}[/tex].

If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.

Thus the option 2 is the correct option.

What is system of equation?

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Given information-

Johann bought 3 blue marbles and 5 green marbles.

The total money paid by the Johann is $11.

Marta bought 4 blue marbles and 2 green marbles.

The total money paid by the Marta is $10.

Suppose the price of the blue marbles is [tex]x[/tex] and price of the green marbles is [tex]y[/tex].

As Johann bought 3 blue marbles and 5 green marbles and paid $11. Thus,

[tex]3x+5y=11[/tex]      .....1

Let the above equation is equation number 1.

As Marta bought 4 blue marbles and 2 green marbles and paid $10. Thus,

[tex]4x+2y=10[/tex]      .....2

Let the above equation is equation number 2.

Thus the equation 1 and 2 are the required set of the equation for the given problem.

Hence the system of equations can be used to find the prices of the blue and green marbles are,

[tex]3x+5y=11[/tex]

[tex]4x+2y=10[/tex]

Thus the option 2 is the correct option.

Answer:

x + 4y

Step-by-step explanation:

Hey there! First, we have to recall back laws of exponent.

[tex]\displaystyle \large{a^{\frac{m}{n}} = \sqrt[n]{a^m} }[/tex]

Now simplify the expressions in surds form.

[tex]\displaystyle \large{\sqrt[3]{x^2+8xy+16y^2} \cdot \sqrt[3]{x+4y} }[/tex]

From x²+8xy+16y², we can convert the expression to perfect square.

Perfect Square

[tex]\displaystyle \large{x^2+2xb+b^2 = (x+b)^2}[/tex]

Therefore, from the expression.

[tex]\displaystyle \large{x^2+8xy+16y^2 = (x+4y)^2}[/tex]

Thus:

[tex]\displaystyle \large{\sqrt[3]{(x+4y)^2} \cdot \sqrt[3]{x+4y}[/tex]

Because both have same surds, multiply them in one.

Surd Property I

[tex]\displaystyle \large{\sqrt[n]{x} \cdot \sqrt[n]{y} =\sqrt[n]{xy} }[/tex]

Therefore:

[tex]\displaystyle \large{\sqrt[3]{(x+4y)^2(x+4y)}[/tex]

Since both are like-terms and multiplying each other, we can apply one of exponent laws.

Exponent Laws II

[tex]\displaystyle \large{a^m \cdot a^n = a^{m+n}}[/tex]

Therefore, we have [tex]\displaystyle \large{\sqrt[3]{(x+4y)^{2+1} } \to \sqrt[3]{(x+4y)^3} }[/tex]

Simplify the expression, we have cube expression inside the cube root. Therefore, we simplify as x+4y as we cancel cube and cube root.

[tex]\bold{x + 4y}[/tex]

Explanation :-

[tex]{(x^{2} +8xy+16y^{2})^{\frac{1}{3} } (x+4y)}^{\frac{1}{3} }[/tex]

Rewriting it into the expression of [tex]a^{2} + 2ab + {b}^{2} [/tex],

[tex]x^{2} + 2x \times 4y + (4y)^{2})^{\frac{1}{3} }(x + 4y)^{ \frac{1}{3} }[/tex]

[tex] = > ((x + 4y)^{2})^{ \frac{1}{3} }(x + 4y)^{ \frac{1}{3} }[/tex]

Now multiplying the fractions as,

[tex] = > ((x + 4y))^{ \frac{2}{3} }(x + 4y)^{ \frac{1}{3} }[/tex]

Now as the bases of the fractions are same, we can multiply directly,

[tex] = > (x + 4y)^{ \frac{2}{3} + \frac{1}{3} }[/tex]

[tex] = > (x + 4y)^{ \frac{3}{3} }[/tex]

As when same numerator and denominator of a fraction is 1, so,

[tex] = > (x + 4y)^1[/tex]

As 1 can be neglected (since it has no specific need in the equation), so,

[tex] = > x + 4y[/tex]

Hence, the answer is [tex]\bold{x + 4y}[/tex]
