How to find the surface area of a trapezoidal prism.

Answer:

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."

Answer:

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

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.

Answer:

88

Step-by-step explanation:

92% = 0.92

0.92(96) = 88.32

88 is rounded to the nearest wing

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.

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:

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%

The selection of the 5-digit number illustrates arrangements

There are 1875 different numbers greater than 50000

The digits of the 5 digit numbers are given as:

3 4 6 7 9

For the number to be greater than 50000, the first digit must be 6, 7 or 9 i.e. 3 numbers.

The other four digits can be any of the 5 numbers.

So, the count of numbers greater than 50000 is:

Count = 3 * 5 * 5 * 5 * 5

Count = 1875

Hence, there are 1875 different numbers greater than 50000

Step-by-step explanation:

The dilation factor of 1/2 moves each point to half its previous distance from the origin.

By using the natural logarithm, we will see that the value of a is 0.33

We know that:

h(x) = x^a

And we know that:

h(27x) = 3h(x).

We can rewrite this as:

(27x)^a = 3*(x)^a

And remember that we can distribute exponents, so the left side can be rewritten as:

(27*x)^a = (27^a)*(x^a)

Then we have:

(27^a)*(x^a) = 3*(x)^a

This means that:

27^a = 3

Now remember the rule:

ln(x^n) = n*ln(x)

If we apply the natural logarithm to both sides, we get:

ln(27^a) = ln(3)

a*ln(27) = ln(3)

a = ln(3)/ln(27) = 0.33

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:

no real solutions

Step-by-step explanation:

x² + 6x + 12 = 0

the general solution :

x = (-b ±sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 6

c = 12

the discriminate is (b² - 4ac).

so,

x = (-6 ± sqrt(6² - 4×1×12))/(2×1)

the discriminate is

6² - 4×12 = 36 - 48 = -12

this is negative, so via the square root of a negative number we get 2 complex (imaginary) solutions.

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.
