simplify (4a-3)(a-9)=4a² -39a+27

Answer:

Y= (-27)

Step-by-step explanation:

Well, I am assuming your just looking for Y. So what I did was you'd want to get rid of the fraction first. I multiplied 3 to all the numbers. so -12(3) = 6(3) + 2y since the bottom 3 from the fraction cancelled out with the (3). so now it would be -36=18+2y. -54/2=2y/2 which leads to -27. So I think Y= -27.

The dimension of the smallest flowering plant is 59/2500 in. long and 129/10,000 in. wide.

To convert Decimal into Fraction form:

Do the following Steps:

Step 1: Make a fraction with the decimal number as the numerator and a 1 as the denominator.

Step 2: Remove the decimal places by multiplication.

Step 3: Reduce the fraction.

Step 4: Simplify the remaining fraction to a mixed number fraction if possible.

Given,

The smallest flowering plant is the flowering aquatic duckweed found in Australia.

And it is 0.0236 inch long and 0.0129 inch wide.

Here we need to write these dimensions as fractions in simplest form.

Rewrite the decimal number as a fraction with 1 in the denominator

So,

=> 0.0236/1 and 0.0129/1

Now, Multiply to remove 4 decimal places. Here, you multiply top and bottom by 10⁴ = 10000.

Then we get,

=> 236/10000 and 129/10000

Now, reduce the fraction by dividing both numerator and denominator by GCF = 4,

=> 59/2500

But the fraction 129/10000 is not reducible.

Therefore, the fraction form is,

=> 59/2500 in. long and 129/10,000 in. wide.

The weight of each bag is 23.25 pounds.

For given question,

Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags.

If all the bags were identical, we need to find the weight of each bag.

Let 'm' be the weight of each bag.

As Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags and all the bags were identical, we get an expression.

8 × m = 187.6

now we solve above expression to find the value of m i.e., to find the weight of each bag.

⇒ 8 × m = 187.6

⇒ m = 187.6 / 8

⇒ m = 23.25 pounds

Therefore, the weight of each bag is 23.25 pounds.

Answer:

Step-by-step explanation:

from the sign it's a right angle, so 90°

90 = x - 8 + 6x

90 + 8 = 7x

98 = 7x

x = 98 : 7

x = 14

------------------

check

90 = 14 - 8 + 6 * 14       (remember pemdas)

90 = 14 - 8 + 84

90 = 90

the answer is good

Find angle 1

Answer:

[tex]\begin{aligned}\textsf{b)} \quad m \angle 1 & =\boxed{6^{\circ}}\\ m \angle 2 & =\boxed{84^{\circ}}\end{aligned}[/tex]

Step-by-step explanation:

From inspection of the given diagram, the sum of the two angles is 90° (indicated by the right angle sign):

[tex]\implies m \angle 1+m \angle 2=90^{\circ}[/tex]

[tex]\implies (x - 8)^{\circ} + (6x)^{\circ} = 90^{\circ}[/tex]

[tex]\implies x-8+6x=90[/tex]

[tex]\textsf{Equation}: \quad \boxed{x-8+6x=90}[/tex]

To find the measure of each angle, solve the equation for x:

[tex]\implies x-8+6x=90[/tex]

[tex]\implies x+6x-8=90[/tex]

[tex]\implies 7x-8=90[/tex]

[tex]\implies 7x-8+8=90+8[/tex]

[tex]\implies 7x=98[/tex]

[tex]\implies \dfrac{7x}{7}=\dfrac{98}{7}[/tex]

[tex]\implies x=14[/tex]

Substitute the found value of x into the expression for each angle:

[tex]\implies m \angle 1=(x-8)^{\circ}[/tex]

[tex]\implies m \angle 1=(14-8)^{\circ}[/tex]

[tex]\implies m \angle 1=\boxed{6^{\circ}}[/tex]

Explanation:

To add a negative number, we are basically subtracting it because of this:
Example:
10 - 5 = 5

10 + (-5) = 5

The negative sign cancels out the positive which makes it into a subtraction problem instead.

Answer: X= -8

Step-by-step explanation:

Rearrange your terms:

5-X=13

-x+5+13

Subtract 5 from both sides

Simplify those = -X = 8

Dive both sides by same factor, -1

The money you will have invested at one year is $560

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are:

Initial = $200

Rate = $30

Let the number of months be n

So, we have

f(n) = Initial + Rate * n

This gives

f(n) = 200 + 30n

There are 12 months in a year

So, we have:

f(12) = 200 + 30 * 12

Evaluate

f(12) = 560

a) r>0 is the domain of A. b) r = (4/2π + 16)^1/2 - 4

A(r) is a function representing the surface area of a cylinder of height = 8inches and radius = r.

A(r) = 2п[tex]r^{2}[/tex] + 16пr

r must be a positive number, as we can't have a radius of negative length, so the domain of A(r)  is r>0.

Solving for r in terms of A is an odd question, and a little challenging but possible using completing the square:

A/2п = [tex]r^{2}[/tex] + 8r

A/ 2п + 16 = [tex]r^{2}[/tex] + 8r + 16

A/2п + 16 = [tex](r + 4)^{2}[/tex]

r =( A/2п + 16) ^1/2 - 4

Therefore we get to know the range of r i.e., r>0 and radius = (A/2п + 16 )^1/2 - 4

Answer: The length of AB =4 units

               The length of BD = 2.4 units.

Step-by-step explanation:

Given data,

                  AD = 3.2 unit

                  BC  = 3 unit

                 CD  = 1.8 units

Find :         AB =? units

                  BD=? units

We can use the formula of Pythagorean theorem,

Define Pythagorean theorem :

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Hypotenuse2 = Perpendicular2 + Base2

                  c2 = a2 + b2

Where “a” is the perpendicular,

“b” is the base,

“c” is the hypotenuse.

Let be a ΔABC,

                           [tex](AB)^{2} = (BC)^{2} +(AC)^{2}[/tex]

From the above formula now  determined  the value of AB and BD,

Firstly , find the value of BD

In ΔBDC, by applying Pythagorean theorem,

                             [tex](BC)^{2} = (BD)^{2} + (DC)^{2}[/tex]             (Eq - 1)

Substitute BC and CD values in equation 1,

            BC  = 3 units and CD = 1.8 units

So,

We can write,

                            [tex]3^{2} = (BD)^{2} +(1.8)^{2}[/tex]

                            9 = [tex](BD)^{2}[/tex] + 3.24

                            [tex](BD)^{2}[/tex] = 9 - 3.24

                            [tex](BD)^{2}[/tex] = 5.76

                             [tex]BD = \sqrt{5.76}[/tex]

                             BD = 2.4 units             (Eq - 2)

Now find the value of AB,

In ΔABD, by applying Pythagorean theorem,

                               [tex](AB)^{2} = (AD)^{2} +(BD)^{2}[/tex]           (Eq - 3)

Substitute AD and BD values in equation 3,

            AD  = 3.2 units and BD = 3 units

So,

We can write,

                                [tex](AB)^{2} = (3.2)^{2} + 3^{2}[/tex]

                                 [tex](AB)^{2}[/tex] = 10.24 + 5.76

                                 [tex](AB)^{2}[/tex] = 16

                                  AB = [tex]\sqrt{16}[/tex]

                                   AB = 4 units

Therefore,

The length of AB =4 units

The length of BD = 2.4 units.

We get the translation rule as (x-4, y+5) for triangle ABC.

We are given a triangle:

ABC where

A = (3, -1)

B = (7, -5)

C = (-2, -2)

And, we are also given the translation of the triangle as A'B'C'

where

A' = (-1, 4)

B' = (3, 0)

C' = (-6, 3)

We need to tell the translation rule for it,

For the x coordinate, we can see that:

- 1 - 3 = - 4

3 - 7 = - 4

- 6 - (-2) = -4

So, the rule for x coordinate will be:

x - 4

Now for y coordinate:

4 - (-1) = 5

0 - (-5) = 5

3 - (-2) = 5

So, the rule for y coordinate will be:

y + 5

Translation rule then becomes:

(x-4, y+5)

Therefore, we get the translation rule as (x-4, y+5) for triangle ABC.
