Answer:

132 sq cm

Step-by-step explanation:

There is a rectangle on top of your shape and a trapezoid below.

Area of a rectangle:

A = length•width

A = 7•4

A = 28sq cm

Area of a trapezoid:

A= 1/2(b_1 + b_2)•h

A=1/2(19 + 7)•8

=1/2(26)•8

=13•8

=104 sq cm

Area of total:

A_rect + A_trapzd

=28 + 104

= 132 sq cm

Answer:

log, 2

Step-by-step explanation:

the answer is log, 2 or c

The solution of the single logarithmic expression that is equivalent to the one shown is,

⇒ log₃ 2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ log₃4 - log₃2

Now, We can simplify as;

⇒ log₃4 - log₃2

⇒ log₃4/2

⇒ log₃ 2

Thus, The solution of the single logarithmic expression that is equivalent to the one shown is,

⇒ log₃ 2

Formulas.

Square: [tex]V = L \times W \times H[/tex]

Square Pyramid: [tex]V = \frac13b^2h[/tex]

b = base.

Let's work on the square first.

Substitute the Length, Width, and Height of the square into the formula:

[tex]V=15 \times15\times15[/tex]

Solve:

[tex]V=15^{3} =3,375[/tex]

Let's work on the square pyramid.

Substitute 225 into the formula, and 9 (height):

[tex]V=\frac{1}{3}(15)^2(9)[/tex]

Solve:

[tex]V=\frac{1}{3}225(9)[/tex]

[tex]V=\frac{1}{3}(2025)[/tex]

[tex]V=675[/tex]

Add each volume:

[tex]3,375+675=4,050 ft^{3}[/tex]

The total volume of the figure is [tex]4,050 ft^{3}[/tex].

Answer:

120 hotdogs would be served if 150 people attend the party.

A ratio is the quantitative relationship between two value, showing how many times one number contains another.

The ratio of hot dogs purchased to number of guests is 1:0.8. For 150 people:

Number of hotdogs = 150 * 0.8/1 = 120 hotdogs

Therefore 120 hotdogs would be served if 150 people attend the party.

The time in seconds that the balloons collided at the highest point is; B: 2.0 seconds

We are told that the water balloons were modeled by the quadratic functions:

y = -7x² + 26x + 6 and y = -6x² + 25x + 4

where;

y = the height in meters

x = the time in seconds after the launch

The time at which they will collide has to be at the same height.

Thus;

-7x² + 26x + 6 = -6x² + 25x + 4

Rearranging this gives;

x² - x - 2 = 0

Using online quadratic equation solver gives us x = 2 or -1. We will take the positive one as x = 2.0 seconds

Answer:

2.5 times 1760 is 4400

Step-by-step explanation:

math lol

Answer:

. We assume, that the number 1760 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 1760 is 100%, so we can write it down as 1760=100%.

4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.

5. Now we have two simple equations:

1) 1760=100%

2) x=2.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

1760/x=100%/2.5%

6. Now we just have to solve the simple

equation, and we will get the solution we are looking for.

7. Solution for what is 2.5% of 1760

1760/x=100/2.5

(1760/x)*x=(100/2.5)*x - we multiply both sides of the equation by x

1760=40*x - we divide both sides of the equation by (40) to get x

1760/40=x

44=x

x=44

Answer:

$21.50

Step-by-step explanation:

10% of $25 is $2.50

4% of $25 is (1% of 25)×4

4% of $25 = $0.25×4

4%=$1

10%+4%=14%

$2.50+$1=14%

$3.50=14%

[tex]x=\frac{1}{2}[/tex]

Step-by-step explanation:

equation of a circle:  [tex](x - h)^2+(y-k)^2=r^2[/tex]

where (h, k) = center and r = radius

From inspection, we can see that the center of the circle = (0, 0)

and the radius = 1

[tex]\implies (x - 0)^2+(y-0)^2=1^2[/tex]

[tex]\implies x^2+y^2=1[/tex]

Substitute [tex]y=\frac{\sqrt{3}}{2}[/tex]  into  [tex]x^2+y^2=1[/tex]  and solve for [tex]x[/tex]:

[tex]\implies x^2+(\frac{\sqrt{3}}{2})^2=1[/tex]

[tex]\implies x^2+\frac{3}{4}=1[/tex]

[tex]\implies x^2=\frac{1}{4}[/tex]

[tex]\implies x=\pm \sqrt{\frac{1}{4}}[/tex]

[tex]\implies x=\pm\frac{1}{2}[/tex]

As point P is in quadrant 1, [tex]x[/tex] is negative, so [tex]x=\frac{1}{2}[/tex]

Alright, lets say the measure of the 3rd angle (the smallest one) is  x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180

A and C are incorrect.

A has the incorrect domain and range.

C represents all whole numbers and all real numbers.

B is correct.

Why?

B represents the whole numbers for where the line has been for x (0 - 14).

B represents the whole numbers for where the lines have been at for y (0 - 85)
