Answer:115.5

Step-by-step explanation:

hope this helped!!

Answer:

115.5m[tex]{}^{2} [/tex]

Step-by-step explanation:

The volume of a prism = 1/2 a × c × h

according to the image a appears to be 3 m she appears to be 7m. and height appears to be 11m.

=> 1/2 a × c × h

=> 1/2 3m × 7m × 11m

multiply 3, 7 and 11

=> 1/2 231

=> 231/2

=> 115.5m[tex]{}^{2} [/tex]

done at all I hope this help please mark me brainest^_^

Answer:

irregular 8-sided polygon or an irregular octagon

Step-by-step explanation:

The shape is an 8-sided polygon, also known as an octagon.

As the side lengths are not equal, it is called "irregular" (if the side lengths were equal then it would be called "regular").

So the shape is an irregular 8-sided polygon, or an irregular octagon.

Answer:

x=31.67[by rounding]

Step-by-step explanation:

As

sin=p/h

Here,

p=2.1

h=4

[tex]solution \\ sin(x )= \frac{2.1}{4} \\ sin(x) = 0.525 \\ \sin(x) = sin(31.66824325 )\\ x = 31.66824325[/tex]

Answer:

31.7°

Step-by-step explanation:

[tex]sin(x)=\frac{opposite}{hypotenus} \\x = sin^{-1} (\frac{2.1}{4} )\\x = 31.668 = 31.7(nearest\ tenth\ of\ a\ degree)[/tex]

Answer:

x = 5°

Step-by-step explanation:

Linear pair: a pair of adjacent angles formed when two lines intersect. The two angles are always supplementary and so their measures sum to 180°.

If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.  The sum of the exterior angles of a polygon is 360°.

Sum of exterior angles:

⇒ 45° + 90° + 25° + 90° + x° + (180° - 140°) + (180° - 115°) = 360°

⇒ 355° + x° = 360°

⇒ x = 5°

Based on the calculations, the distance covered by Lea is equal to 336 kilometers.

Given the following data:

Mathematically, speed is given by this formula;

[tex]Speed = \frac{distance}{time}[/tex]

Next, we would calculate Hanna's speed by using the above formula:

[tex]Hanna's\; speed = \frac{252}{3}[/tex]

Hanna's speed = 84 km/h.

For Lea's distance:

[tex]Distance = speed \times time\\\\Distance = 84 \times 4[/tex]

Distance = 336 kilometers.

The second system of linear inequalities has the point (3, -2) in its solution set.:

y > -2 and y ≤ (2/3)x - 4

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The system of linear inequalities is given as follows:

1. y<-3

y≥(2/3)x-4

2. y>-2

y≤(2/3)x-4

Now, checking the given point (3, -2) satisfies the linear inequalities:

Substituting the values x = 3 and y = -2 in the inequalities 1, we get:

-2 > -2 (which is false)

For the inequalities 2, we get:

-2 ≤ (2/3)(3) - 4 => -2 ≤ -2 (which is true)

Therefore, only the second system of linear inequalities has the point (3, -2) in its solution set.

Answer:

  D, E

Step-by-step explanation:

Each vector represents the horizontal and vertical translation amounts:

  [tex]\left[\begin{array}{c}\text{translation right}\\\text{translation up}\end{array}\right][/tex]

Translation left or down will result in negative values for the corresponding translation amounts.

__

We can consider only the lower-left corner to determine the amount of translation.

horizontal: 1 to -4, so -4-1 = -5 units

vertical: 2 to 0, so 0 -2 = -2 units

The translation vector is ...

  [tex]\left[\begin{array}{c}\text{-5}\\\text{-2}\end{array}\right]\qquad\text{matches choice D}[/tex]

__

horizontal: -4 to -1, so -1 -(-4) = -1 +4 = 3 units

vertical: 0 to -4, so -4 -0 = -4 units

The translation vector is ...

Step-by-step explanation:

if the hat is 4 TIMES the baseball cap then u should multiply. anytime “times” is in a sentence like that it’s an automatic flag/reminder that multiplication is needed

Answer:

D.

Step-by-step explanation:

The matching shirt costs 4 times as much as the cap; The cap is $8. In that case, the question just told us the answer. 4 times $8 = 4*8 or 8*4 = $32. So if you had to determine the cost, the shirt is $32.

The best equation form is Slope-Intercept form (y=mx+b), where the letter m stands for the slope of the line and the letter b stands for the y-intercept of the line (where the graph touches the y-axis).

Why is Slope-Intercept the best form?

Because if you know y=mx+b, and you know what every variable means (m & b), then all you have to do is look at the equation and determine the y-intercept.

Example:

Suppose we have the following equation:

           [tex]\bold{y=0.7x-6}[/tex]

What is the y-intercept of this line?

Hint: Look at the equation.

That's right. The y-intercept is -6.

Hence, the best equation form is

[tex]\boxed{\boxed{\bold{Slope-Intercept\:Form}}}[/tex]

Hope everything is clear.

Answer: Carla: 5, Jim: 6, Peter: 9

Step-by-step explanation:

Let c be Carla's age, j be Jim's age, and p be Peter's age.

We can set up equations.

We already know that c = 5

j + 13 = p

p-1 = 2(c - 1 + j - 1)

Combine like terms:

p - 1 = 2(c + j - 2)

Distribute:

p - 1 = 2c + 2j - 4

p + 3 = 2c + 2j

We can plug in the value of 5 for c.

p + 3 = 10 + 2j

2j + 7 = p

We can plug in j + 13 for p.

2j + 7 = j + 13

Combine like terms:

j = 6

Therefore, p = 6 + 13 = 9

Answer:

A = 90.25pi sq m

OR = 361pi/4 sq m

Step-by-step explanation:

If the circumference is 19pi, then the diameter is 19.

C = pi•d

19pi = pi•d

19 = d

If the diameter is 19, then the radius is 9.5.

The radius is always half of the diameter.

Then we can find the area.

A = pi•r^2

=pi•9.5^2

=90.25pi

We don't often see a decimal number coefficient for pi. So as an improper fraction, 90.25 which is 90 1/4 is

(90×4)+1 over 4

= 361/4

Area = (361/4)pi

=361pi/4 sq meters

Hope that helps!

The answer would be 28.

Because m=5 and n=3 we would substitute those values in the corresponding equation. So our new equation would be 2(5) + 6(3). From here we follow the rules of PEMDS (Parentheses, Exponents, Multiplication, Division, Subtraction [or addition if present]). Now we multiply our values and then add. 2×5 is 10 and 6×3 is 18. 10+18=28, thus giving us the answer of 28.

Answer:

X=1

Y=7

Step-by-step explanation:

Add both equations

(-2x) -4y +(-x) +y=-24

-3x-3y=-24. Take - 3 common factor

-3(x+y)=-24. Devide both sides by - 3

X+y=8

Adding the second equation with x+y=8

-x+y +x+y=14

2y=14

Y=7

In equation (x+y=8) substitute y with 7

X+7=8

x = 21.5

Step-by-step explanation:

x = number of games.

6x = 6 games.

Since billy scores 129 points in these 6 games, that would mean we can set up this equation:

6x = 129.

Now divide both sides by 6 to get x alone.

x = 21 ½

The line of best fit of the student model shows the relationship between variables on a scatter plot

The question is incomplete; So, I will make use of a dataset with the following calculation summary from a graphing calculator

So, the equation of the line of fit is:

[tex]y = -0.1x + 50[/tex]

In (a), we have:

So:

The slope means that the number of students reduces each year by a factor of 0.1, while the y-intercept means that the initial number of students is 50

This means that x = 11.

So, we have:

[tex]y = -0.1*11 + 50[/tex]

[tex]y = 49[/tex]

Hence, the number of students in year 11 is 49
