-6(2+a)=-48 what is the value for a
​

Answer:

Step-by-step explanation:

First part of the second factor.

Start by noticing that you are not going to get 7s^2 with the factor you have. So the first thing to do is to write the second factor as

(s + 3)  (7s

Sign

The next problem is to figure out what the sign following the 7s is. The 12 holds the answer to that.

12 is positive. So what ever follows must also be positive. Otherwise you will get a negative for the 12.  So now you have

(s + 3)(7s +

What comes after the Plus Sign?

Last step. you need a number that when multiplied by 3 will give you 12. That has to be 4

(s + 3)(7s + 4) This is your answer.

Answer:

250 batches of muffins and 0 waffles.

Step-by-step explanation:

-1

If we denote the number of batches of muffins as "a" and the number of batches of waffles as "b," we are then supposed to maximize the profit function

P = 2a + 1.5b

subject to the following constraints: a>=0, b>=0, a + (3/4)b <= 250, and 3a + 6b <= 1200. The third constraint can be rewritten as 4a + 3b <= 1000.

Use the simplex method on these coefficients, and you should find the maximum profit to be $500 when a = 250 and b = 0. So, make 250 batches of muffins, no waffles.

You use up all the dough, have 450 minutes left, and have $500 profit, the maximum amount.

Answer:

all five are dangerous

checking his phone while crossing the street

driving impaired

driving unbuckled

hiking alone

not wearing safety goggles

All the situations described - Distracted walking, Drinking and driving, Not wearing a seatbelt, Hiking alone, and Not wearing safety goggles in a possibly hazardous environment - are dangerous.

All of the scenarios given can be considered as dangerous. Distracted walking, as portrayed by Dan who checks his cell phone while crossing the street, risks accidents because the person is not fully aware of his surroundings. Drinking and driving, like Enrique after a couple of beers, is extremely dangerous, often leading to severe accidents. Not wearing a seat belt while driving, regardless of the drive's duration, puts Emily in danger. Anita's situation where she is hiking alone can be dangerous due to the risk of injury, and going without help or immediate assistance. Lastly, Lorena's situation is hazardous because safety goggles are crucial for protecting the eyes during a science presentation, especially if it involves chemicals or physical contraptions.

Answer: [tex]158cm^2[/tex]

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

[tex]SA = 2(wl +lh + hw)[/tex]

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this rigth rectangular prism  has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

[tex]SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2[/tex]

Answer:

Surface area of prism = 158 cm²

Step-by-step explanation:

Points to remember

Surface area of rectangular prism = 2(lb + lh + bh)

Where l - Length, b - Breadth and h - Height

To find the surface area of prism

Here l = 8 cm, b = 3 cm and h = 5 cm

Surface area = 2(lb + lh + bh)

 = 2[(8*3)  + (8 * 5) + (3 *5)]

 = 2[24 + 40 + 15]

 = 2 * 79

 =158 cm²

Surface area of prism = 158 cm²

Final answer:

After applying a $5 coupon to his $16, Tyler is left with $11. Given the cost of one bottle of olive oil is $7, Tyler can only purchase 1 bottle because he cannot buy a fraction of a bottle.

Explanation:

The student's question involves basic arithmetic operations and budget management, which falls under the subject of Mathematics. Tyler can use the $5 coupon to reduce the total cost of his purchase. To determine how many bottles of olive oil he can buy, we need to subtract the coupon value from the amount of money he has:

Now, we divide the amount left by the cost of a single bottle of olive oil:

Since Tyler cannot buy a fraction of a bottle, he can buy only 1 bottle of olive oil with the money he has after applying the $5 coupon.

Answer:

$370

Step-by-step explanation:

You already have 90 dollars so we can put that to the side for right now

If you're charged $35 at an hourly rate for 8 hours then you have to multiply the two together

30 x 8 = 240

5 x 8=40

240 + 40=280

Now is when your $90 dollars comes in. Now just add the two together and you'll end up with your final answer

280+90=370

Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{5}{12}[/tex] is the same as multiplying [tex]\frac{3}{4}[/tex] by [tex]\frac{12}{5}[/tex].

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!

Answer:   [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.

To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.

Then, the reciprocal of the fraction [tex]\frac{5}{12}[/tex] is:

[tex]\frac{12}{5}[/tex]

Therefore:

Answer: ur inbox in y=my+b form

Step-by-step explanation:

Answer:

x = 1.25

y = 0.75

Step-by-step explanation:

Let $x be the cost per pound of apples

Let $y be the cost per pound of bananas

5x + 3y = 8.5  --- (1)

3x + 2y = 5.25  --- (2)

From (1),

3x + 1.8y = 5.1  --- (1a)

Subtract (1a) from (2),

(3x + 2y) - (3x + 1.8y) = 5.25 - 5.1

3x - 3x + 2y - 1.8y = 0.15

0.2y = 0.15

y = 0.15 / 0.2 = 0.75

x = [ 5.25 - 2(0.75) ] / 3 = 1.25

Answer:

The answer is A.

Step-by-step explanation:

We only have to test one coordinate to find the answer. The original coordinate for N is (-1, -1). Using the formula, N' is (0, -2).

You see, it's quite easy. All you need to do is find the coordinates of FNQ, then add the 1 to the x values and subtract 1 from the y values as stated in the translation rule.  

However, in your case, you don't have numbers on your graph but you can easily draw some. Be mindful of the quadrants.

Let's try out point F just for gags.

F = (3, 3)  

(Technically you only need one point to determine the answer.)

Now, apply rule: x + 1, y - 1

(3, 3) becomes (4, 2)  

Now, which multiple choice answer contains that specific point for F?  

Choice A.

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

As, per the graph

slope= rise/ run

slope= 3/2

and, y- intercept is of 2 units.

So, equation of slope intercept form will be,

So, option D is correct

Option (D) Multiply 1/2 base by altitude should be used to find the area of a triangle.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

Answer:You haven't attached a picture but this is what your line should look like

Step-by-step explanation:

For this equation you simply have to graph it.

First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.

Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.

Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

The statement most accurately describes the relationship between

segments of the triangles formed by the beam is AC < DF

Step-by-step explanation:

* Lets study the figure to answer the problem

- There are two triangles ABC and DEF

- AB = BC

- DE = EF

- AB = DE

∴ AB = BC = DE = EF

- m∠ABC = 45°

- m∠DEF = 60°

∵ The measure of angle ABC is smaller than the measure of

   angle DEF

∴ The opposite side to the angle ABC is shorter than the opposite

   side of angle DEF

∵ AC is the opposite side to angle ABC

∵ DF is the opposite side to angle DEF

∴ AC is shorter than DF

∴ DF > AC

∴ AC < DF

* The statement most accurately describes the relationship between

  segments of the triangles formed by the beam is AC < DF
