Answer:

115.15 cm²

Step-by-step explanation:

The area of a trapezoid = 1/2 (b1 + b2)h

Where:

b1 = first base = 8.2 cm

b2 = Second base = 15.3 cm

h = height = 9.8 cm

Hence, Area of the trapezoid =

1/2 (8.2 + 15.3) × 9.8

= 1/2 × (23.5) × 9.8

= 115.15 cm²

Therefore, the area, in square centimeters, of the trapezoid below is 115.15 cm²

Answer:

Total Cost in a day is . Profit function is . And the revenue function is . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.

Step-by-step explanation:

-90

The break-even point for this bookstore is 15, i.e. correct answer is,

C. n = 15.

Here, we have,

given that,

A bookstore costs $90 a day to keep open,

and it spends $12 for each book that it sells.

If each book sells for $18,

now, we know that,

Breakeven quantity = fixed cost / price – variable cost per unit

now, we have,

$90 / (18 - 12)

=$90 / $6

= 15

so, n = 15

Hence, The break-even point for this bookstore is 15, i.e. correct answer is, C. n = 15.

Step-by-step explanation:

Answer:

A) experiment B) Survey C) observational study

Step-by-step explanation:

A could either be experiment or observation but you are experimenting with different types of music and plants so experiment makes more sense to me.

B is a survey because you are asking a group about a topic and recording the answer which is essentially a survey.

C is an observation because you are checking to see improvement, no improvement, or stays the same ie: meaning you have to observe what happens before and after

Answer:

$52

Step-by-step explanation:

Given data

Price of blender= $65

Coupon = 20%

Let us find the amount of the coupon

=20/100*65

=0.2*65

=$13

Hence the amount of the coupon is $13

The total price Nathan pays is

=65-13

=$52

The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."

Step-by-step explanation:

Finding the average skid distance:

[tex]Average=\frac{70+71+72}{3}=\frac{213}{3}=71[/tex]

Calculating the skid:  

[tex]S=\sqrt{30 \times D \times f\times n}\\\\[/tex]  

   [tex]=\sqrt{30 \times 71 \times 0.78\times 0.95}\\\\=\sqrt{1,578.33}\\\\=39.73[/tex]

Answer:  x+(x+1)+(x+2) = 63

This is because x is the smallest number, so x+1 is the next value up, and x+2 is the value after that. The parenthesis are optional. I used them to separate out the three expressions. We can simplify the left side to 3x+3, which means that equation in bold is the same as 3x+3 = 63. So there are few ways we can form the equation.

You have the correct answers for the other boxes:

20+21+22 = 63

Nice work.

20, 21, 22

Step-by-step explanation:

Let x = the smallest integer of the three consecutive ones

(x + 1) = the next consecutive integer after x

(x + 2) = the next consecutive integer after (x + 1)

The sum of these three should add up to 63 so

x + (x + 1) + (x + 2) = 63

This simplifies to

3x + 3 = 63

Solving for x, we get

x = 20

Therefore, the three consecutive integers whose sum add up to 63 are 20, 21 and 22.

Answer:

Addition: -1 + -3 = -4

Subtraction: (-4) - 5 = -10

Step-by-step explanation:

Since adding a positive makes a negative number stay negative, it equals -4.

Then by subtracting a negative with a positive (5), the number stays negative once again, which then equals -10.

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

Explanation:

Angles E and G are congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides EF = FG

Let x be the measure of angle E and angle G.

Adding all three angles of any triangle always gets us 180 degrees.

E+F+G = 180

x+106+x = 180

2x+106 = 180

2x = 180-106

2x = 74

x = 74/2

x = 37

Angles E and G are 37 degrees each

Answer:

37 degrees for both angles

Step-by-step explanation:

Any triangle is equal to 180 degrees

therefore, 180 - 106 = 74

74 / 2 = 37

I divided by 2 because you need an amount of 2 angles.

Thus, angles m<E and m<G are both equal to 37 degree

To check:

106 + 37 + 37 = 180

Answer:

its 94 on deltamath just did it

Step-by-step explanation:

Let t=0 represent the year 1997

Starting Value: 690

Write function:

y=690(b)^t

Now find the b-value:

y=390 when t=4 (2001−1997)

390=690(b)^4

390/690=690(b)^4/690

0.56521739=b^4

(0.56521739)^1/4=(b^4)^1/4

0.86706944=b

Write Complete Function:

y=690(0.86706944)^t

Find value in 2011 (use t=14):

y=690(0.86706944)^14

y=93.67062063

y≈94

Answer:

They are about 3.6 miles away from each other.

Step-by-step explanation:

2²+3² = C²

13=C²

√13 = C

C = 3.6

The distance between Josh and Ben is 3.6 miles

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that Josh and Ben spotted a bear in the woods while riding their bikes. Josh rode 3 miles north and Ben rode 2 miles east.

The formula of the Pythagorean theorem is given as,

C² = a² + b²

C² = 2²+3²

C² = 13

C = √13

C = 3.6

Therefore, the distance between Josh and Ben is 3.6 miles

Answer:

[tex]y =\frac{4}{5}x-6[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y =mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (5,-2) and (15, 6)

[tex]=\frac{6-(-2)}{15-5}\\=\frac{6+2}{15-5}\\=\frac{8}{10}\\=\frac{4}{5}[/tex]

Therefore, the slope of the line is [tex]\frac{4}{5}[/tex]. Plug this into [tex]y =mx+b[/tex]:

[tex]y =\frac{4}{5}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y =\frac{4}{5}x+b[/tex]

Plug in one of the given points and solve for b

[tex]6=\frac{4}{5}(15)+b\\6=12+b[/tex]

Subtract 12 from both sides of the equation to isolate b

[tex]6-12=12+b-12\\-6=b[/tex]

Therefore, the y-intercept of the line is -6. Plug this back into [tex]y =\frac{4}{5}x+b[/tex]:

[tex]y =\frac{4}{5}x-6[/tex]

[tex]t=\sqrt{\dfrac{2s}{a}}[/tex]

Step-by-step explanation:

The given equation is :

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

Where

s is displacement

u is the initial velocity

a is acceleration

t is time

If u = 0, the above equation become,
