Simplify 1260g:5400g

Answer:

24 square centimeters

Step-by-step explanation:

Parallelagram Area fromula is A=bh

which is Area equals base times hieght

You just plug in the infromation in the problem and solve

A=bh

A=4x6

A=24

The solutions are:

[tex]x =3+2\sqrt{3}i\\\\\:x=3-2\sqrt{3}i[/tex]

Solution:

[tex]f(x) = x^2 - 6x + 21[/tex]

We have to find solutions when f(x) = 0

[tex]x^2 - 6x + 21 = 0[/tex]

Solve by quadratic formula

[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\mathrm{For\:}\quad a=1,\:b=-6,\:c=21\\\\x=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}[/tex]

[tex]x = \frac{6 \pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}\\\\Simplify\\\\x = \frac{6 \pm \sqrt{36 - 84}}{2}\\\\x = \frac{6 \pm \sqrt{-48}}{2}\\\\x = \frac{6 \pm i \sqrt{48}}{2}\\\\simplify\\\\x = \frac{6 \pm 4\sqrt{3}i}{2}\\[/tex]

[tex]x = 3 \pm 2 \sqrt{3} i[/tex]

We have two solutions:

[tex]x = 3 + 2 \sqrt{3} i\\\\x = 3 - 2 \sqrt{3} i[/tex]

Thus the solutions are:

[tex]x =3+2\sqrt{3}i\\\\\:x=3-2\sqrt{3}i[/tex]

Answer:

I think it's $12.80 but I might be wrong.

Each person will have to contribute $6.40.

To find out how much money each person will have to contribute to get to the university and back, we can first find the total cost of the trip. The distance to the university and back is 2 times the distance to the university, which is 105 miles. So the total distance is 2 * 105 = 210 miles. Roberta's car can travel 8.2 miles per dollar of gasoline, so the total cost of the trip is 210 / 8.2 = 25.61 dollars. Since Roberta and three friends are splitting the cost evenly, each person will have to contribute 25.61 / 4 = 6.4025 dollars. Rounding to the nearest cent, each person will have to contribute $6.40.

Answer:

1.8

Step-by-step explanation:

12/4 - 1.2

3 - 1.2 = 1.8

Answer:

18

Step-by-step explanation:

First you would have the divide 2 and 12 which is 6 then you would muplty 6 by 3 because you need to find how many fictional book which is 18

p. ls I am 99% sure this explanation is right

The number of fiction books is 18.

Ratio expresses the relationship between two values. It is the number of times that one value is contained within other value(s).

Number of books = (number of mystery books x sum of ratios) / ratio of mystery books

(12 x 5) / 2 = 30 books

number of fiction books = (ratio of fiction books / sum of ratios) x total number of books

3/5 x 30 = 18 books

option c {(0, -5), (2,9), (-3, -26)}  is correct  . All others doesn't satisfy the equation .

Step-by-step explanation:

We have , If y = 7x - 5, following set of ordered pairs {(0, -5), (2,9), (-3, -26)} . Let's check for this

(0, -5):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(0)-5[/tex]

⇒ [tex]y =-5[/tex]

So , it's correct ordered pair .

(2,9):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(2)-5[/tex]

⇒ [tex]y =9[/tex]

So , it's correct ordered pair .

(-3,-26):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(-3)-5[/tex]

⇒ [tex]y =-26[/tex]

So , it's correct ordered pair .

Therefore, option c {(0, -5), (2,9), (-3, -26)}  is correct  . All others doesn't satisfy the equation .

Answer:

[tex]F(2)= \frac{1}{32} [/tex]

Step-by-step explanation:

The given function is

[tex]F(t) = 2 \cdot \: \frac{1}{{2}^{3t} } [/tex]

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} } [/tex]

We multiply the exponent in the denominator to get:

[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{6} } [/tex]

We evaluate to get:

[tex]F(2) = 2 \cdot \: \frac{1}{64} [/tex]

We now cancel the common factors to get:

[tex]F(2) = \frac{1}{32} [/tex]

Answer:

y = -3/4x + 5

Step-by-step explanation:

Slope intercept form is y=mx + b

First, find the slope of the line. the points are (0,5) and (4,2), as marked. To find the slope, you do (y2-y1)/(x2-x1). Fill in the numbers and you get

(2-5)/(4-0). Simplify and you get -3/4 is the slope. Then, to find b, you have to fill in one coordinate pair and the slope into y=mx+b. So, I used (0,5).

5=(-3/4)(0) + b

Then you get 5=b by solving, and you fill in the slope and the y intercept in the slope intercept form equation. y = -3/4x +5. This is how you find the answer.

The answer is 8 months

Step-by-step explanation:

The new computer tablet is $460. She paid $100 at the time so I subtracted $100 from $460, which equals to $360. The monthly payments are $45 a month, so I divided $360 by $45, which equals 8. It takes 8 more months to finish the payment.

Answer:

9 and 10

Step-by-step explanation:

Consider perfect squares on either side of 92, that is

81 < 92 < 100, thus

[tex]\sqrt{81}[/tex] < [tex]\sqrt{92}[/tex] < [tex]\sqrt{100}[/tex], that is

9 < [tex]\sqrt{92}[/tex] < 10

Final answer:

To find two consecutive whole numbers that the square root of 92 lies between, we calculate the square root of 92 to determine its approximate value, which falls between 9 and 10.

Explanation:

To find two consecutive whole numbers that √92 lies between, we need to calculate √92 to determine its approximate value. Since 92 is between 81 (9²) and 100 (10²), the square root of 92 lies between 9 and 10. Therefore, the consecutive whole numbers are 9 and 10.

Mariko caught 10 rockfish and 14 bluefish on her fishing trip.

Let's define the number of rockfish caught as x and the number of bluefish caught as y.

According to the given information, the average weight of each rockfish is 2.5lbs and the average weight of each bluefish is 8lbs.

We can form two equations based on the total weight of all the fish and the total number of fish caught:

We can solve this system of equations to find the values of x and y by either substitution or elimination method. Using the elimination method:

Multiplying Equation 1 by 2.5, we get 2.5x + 2.5y = 60

Subtracting this equation from Equation 2, we get 8y - 2.5y = 137 - 60

Simplifying, we have 5.5y = 77

Dividing both sides by 5.5, we get y = 14

Substituting this value back into Equation 1, we have x + 14 = 24

Simplifying, we get x = 10

Therefore, Mariko caught 10 rockfish and 14 bluefish.

Answer:

No.

Step-by-step explanation:

3/4 cannot be simplified. Neither can 7/8. Also, 3/4 as a decimal is 0.75, and 7/8 as a decimal is 0.875.

Answer:

No

Step-by-step explanation:

Is 3/4 less than 7/8? Is 3/4 smaller than 7/8? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

3/4 = 0.75

7/8 = 0.875

Then, we compare the two decimal numbers to get the answer.

0.75 is less than 0.875.

Therefore, 3/4 is less than 7/8 and the answer to the question "Is 3/4 less than 7/8?" is yes.

The value of x is 13°.

Solution:

In triangle, sum of all the interior angles = 180°

m∠A + m∠B + m∠C = 180°

(3x)° + (4x – 1)° + 90° = 180°

3x° + 4x° – 1° + 90° = 180°

7x° + 89° = 180°

Subtract 89° from both sides of the equation, we get

7x° = 91°

Divide by 7 from both sides of the equation, we get

x° = 13°

The value of x is 13°.

Answer:

90 calories in total

Step-by-step explanation:

We can solve this equation through the following steps:

Step One: Since we are told that a banana is 20 less calories than an orange, we can create the Let Statements:

Let x= the calories in a banana

Let x-20=the calories in an orange

Step Two: Create an equation

Since we are told "7 bananas have the same calories as 9 oranges" we translate"

7x=9(x-20) Distribute

7x=9x-180 Subtract 9x from both sides of the equation

7x-9x=-180 Simplify

-2x=180 Divide both sides by -2

x=90

∴There are 90 calories in a banana.

Answer:

6.8 quarts of white paint

Step-by-step explanation:

If you make 5 parts equal to 0.5 you will have 17 parts blue paint. 17 divided by 5 (to get how many parts we are using) is 3.4. One part blue paint is 3.4 quarts. Times that by two to get how many parts of white paint. We need 6.8 quarts of white paint.

Answer: 8x+3x=12x+9

The number is -9.

Step-by-step explanation: Combine like terms.

11x=12x+9

Subtract 12x from the other side. 11x-12x= -1x

-1x+9

Divide by -1 to isolate x.

-1/-1 cancels out.

9/-1= -9

x=-9

Plug in -9 to check your answer if you want to double check.

y=(-2)²+4(-2)+8=4

When x=0,

y=(0)²+4(0)+8=8

When x=2,

y=(2)²+4(2)+8=20
