Answer:

n^2 + 1

Step-by-step explanation:

Let the unknown number be n.  Then "a number squared and four" is

n^2 + 4, and 3 fewer than this result is

n^2 + 3 - 3, or n^2 + 1

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

[tex] \frac{4}{7} \times y[/tex]

Remainder =

[tex]y - \frac{4}{7}y = \frac{3}{7} y[/tex]

Amount spent on frozen foods = two-thirds of remainder = $22

[tex] = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y[/tex]

[tex]\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77[/tex]

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

[tex] = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44[/tex]

Answer:

y= -x+2

Step-by-step explanation:

Using the equation, y = mx+b, you know you have to find the slope. Find the slope using two coordinate points, (-2,4) and (0,2).

Subtract 2-4/0+2 - the answer is -1. Your slope is -1 and the y axis is given so the equation is y=-x+2

Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!

Answer:

The equation of the line is y = 1/2x - 3/2

Step-by-step explanation:

Plug in point (-3, 3) with slope 1/2 into y = mx + b

-3 = 1/2(-3) + b

-3 = -3/2 + b

+3/2     +3/2

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

-3/2 = b

hence, y = 1/2x - 3/2

Answer:

40°

Step-by-step explanation:

Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.

After rotational transformation, the measure of angle ∠A' = 40°.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The diagram shows the two triangles.

Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.

From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.

Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]

Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

Answer:

240g of 10% salt solution and 160g of 5% salt solution

Step-by-step explanation:

Simpler way:

Let X be the amount of 10% salt solution and Y be the amount of 5% salt solution.

Then X:Y = 3:2 as you need more 10% salt solution than 5% salt solution to create a 8% salt solution. The ratio 3:2 is given as 10 - 8 = 2 and 8-5 = 3.

If X:Y = 3:2 = 60:40, then 60% of the 400g of 8% salt solution must be the 10% solution and 40% of the 400g of 8% salt solution must be the 5% solution. Therefore, 240g of the 10% salt solution and 160g of the 5% salt solution is needed to create 400g of the 8% salt solution.

This is correct as the amount of salt in the solution is equal to (10% X 240g = 24g) + (5% of 160g = 8g). So the total amount (24+8) 32g should be equal to the amount of salt in the 400g of 8% salt solution.

8% of 400g = 32g which means our answer is correct.

More complex way:

A more complex way is to use algebra.

Let X be the amount of 10% salt solution and Y be the amount of 5% salt solution.

X + Y = 400g

and 10% of X + 5% of Y = 8% of 400

so 1/10 X + 1/20 Y = 32

2X + Y = 640 (multiply the previous equation by 20)

Now from the first line we know that X + Y = 400

So if we subtract (2X+Y) by (X+Y) we can get the value of X:

(2X+Y) - (X+Y) = 640 - 400

2X+Y - X - Y = 240

Therefore X = 240

And since X + Y = 400, Y = 160.

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x
