Answer:

1/4x^2 + 7x + 49

Step-by-step explanation:

Use binomial theorem (a + b)^2 = a^2 + 2ab + b^2 to expand (1/2x + 7)^2

Answer:

He forgot to multiply by 1/2 when finding the area of the above triangle.

Now we find the correct area;

A = BH x 1/2 (formula for finding area of triangle)

A = 10 x 24 x 1/2

A = 240 x 1/2

A = 240/2

A = 120

Now the rectangle's formula which is just (W x L) where "w" is the width and "l" is the length;

A = W x L

A = 24 x 15

A = 360

Now we add both the sums of the two areas:

120 + 360 = 480 square feet, the information provided here is your explanation.

Answer: 60

Step-by-step explanation: if you count the length and the width and multiply them you will get your answer, i did 15 (amount of units going down) and 8 (amount of unites going sideways) and multiplied them, 15 x 8 = 120 then half of that is 60

Answer:

  MO = 25

Step-by-step explanation:

Point O between parallel lines PQ and MN divides segment PM in the same proportion that it divides segment QN.

  MO/OP = NO/OQ

  MO/20 = 20/16 . . . . . . use the given numbers

  MO = 20(20/16) . . . . . multiply by 20

  MO = 25

Answer:

equation

Step-by-step explanation:

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.

[RevyBreeze]

Answer:

equation

Step-by-step explanation:

To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

Answer:

24.4 > 24.34

Step-by-step explanation:

Tenth place value can be any number more than the tenth value in 24.34.

In the decimal number 24.34, the tenth value is 3. So, it should be more than 3

Options can be any one of these

24.4  or

24.5 or

24.6

Answer:

Values (tenths) that would make the number comparison 24._ > 24.34 true would be:
- 4
- 5
- 6

24.40 > 24.34
24.50 > 24.34
24.60 > 24.34

All other options provided would make the left side of the comparison less than the right side of the comparison.

Second option

Step-by-step explanation:

We will use the process of elimination to find the answer:

First option:
[tex]4+(8\times4)\div6+7[/tex]
[tex]8\times4=32[/tex]
[tex]4+32\div6+7[/tex]
[tex]4+32=36[/tex]
[tex]36\div6+7[/tex]
[tex]36\div6=6[/tex]
[tex]6+7=13[/tex]
[tex]=13[/tex]

Second option:
[tex](4+8)\times4\div6+7[/tex]
[tex]4+8=12[/tex]
[tex]12\times4\div6+7[/tex]
[tex]12\times4=48[/tex]
[tex]48\div6+7[/tex]
[tex]48\div6=8[/tex]
[tex]8+7=15[/tex]
[tex]=15[/tex]

Which means your answer is the second option or "4 + (8 × 4) ÷ 6 + 7."

Given parameters:

   Expression;

                        6¹²

Identify the exponent and the base in the expression;

                         6¹²

An exponent is a power to which a number or variable is raised.

Generally, it signifies the number of times a number should be repeatedly multiplied.

The base is the number that is being multiplied.

So, in this problem, exponent is 12 and base is 6.

Answer:

No

Step-by-step explanation:

To find how much something is a percent of another number, divide it by said other number

20/40 = 0.5

0.5 × 100 = 50%

The first one is a 50% increase

Then, 40/20 = 2

2 × 100 = 200%

It is a 200% decrease

So no, because 50% doesn't equal 200%

Block Y has the smallest acceleration

Answer:

y = 2x + 3

Step-by-step explanation:

to find the perpendicular line then you have to find the negative reciprocal which is 2 and to get that you flip the fraction and change the sign so

(-1/2) → 2/1 or 2

the y-intercept coordinate is (0, 3) so the y-intercept is 3

Slope of the Perpendicular line=2

Equation of line in point slope form

In a case whereby Mary sells fruit with four of her friends If the earnings are divided evenly the amount they must  make in order for each person to earn 30 is 150.

Since 4 of them wereinto the business aimimg to share the profit in erqual amount then the  business should make [30*(1+4) ]= (30*5 )= 150 dollars total earnings.

Therefore, If the profits from selling fruit with Mary's four friends are divided equally, they will need to make 150 in order for each individual to make $30.

The distance from point L to point M is 17

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is calculated as follows:

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Point L has coordinates (-10,-9) and point M has coordinates (-2,6).

Calculate the distance between L and M:

[tex]d=\sqrt{(6+9)^2+(-2+10)^2}[/tex]

[tex]d=\sqrt{15^2+8^2}[/tex]

[tex]d=\sqrt{225+64}=\sqrt{289}[/tex]

[tex]\boxed{d=17}[/tex]

The distance from point L to point M is 17

Starting bpm = 91

Resting bpm = 72.8

=========================================================

Explanation:

A 30% increase is represented by the multiplier 1.30 because

100% + 30% = 1.00 + 0.30 = 1.30

So Krystal's initial heart rate is 1.30*70 = 91 bpm.

If you wanted, you can think of it like this

30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.

-----------

To decrease by 20%, we use the multiplier 0.80 since

100% - 20% = 1.00 - 0.20 = 0.80

Losing 20% of something means we keep the remaining 80%

So,

80% of 91 = 0.80*91 = 72.8 bpm.

-----------

Here's one way to find the final bpm in one single line

1.30*0.80*70 = 72.8

in which you could write it like this

(1 + 0.30)*(1 - 0.20)*(70) = 72.8

The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.

i THINK 43% but im not for sure

Step-by-step explanation:

14% of 50 is 7

so 50-7=43

43(percent there)+7(percent gone)=50 (number of students)

SO 43% is still there.
