Answer 1

Question:- Find the area of the base?

Given in figure:-

length:- 17mm width :- 34mm

Formula :-Area = length × width

Explanation :-

[tex]area = l \times w \\ area = 34 \times 17 \\ area = \: 578 {mm}^{2} [/tex]

Answer:- 578mm² = area

Question:- Find the volume of the whole figure?

Given in figure:- Length = 17mmwidth = 34mmheight = 6mm

Formula :-

Area of the side which is a 2D triangle× length.Area of the triangle = ½× Width× height.

Explanation :-

[tex]Area \: of \: the \: triangle = ½× width×height. \\ area \: = \frac{1}{2} \times 34 \times 6 \\ area = 34 \times \frac{ {\cancel6} {}^{ \: \: 3} }{ \cancel2} \\ area = 34 \times 3 \: {mm}^{2} \\ area = 102 {mm}^{2} [/tex]

Now for volume :-

[tex]volume \: = area \: \times length \\ vol = 102 \times 17 \: \: {mm}^{3} \\ vol \: = 1734{mm}^{3} [/tex]

Answer:- 1734 mm³ = volume

Angles around a point

Answers

Answer:

x=45, y=45, z= 131

Step-by-step explanation:

x and y makes up a right angle (90). You can even;y split them in half, which is 45 degrees. Therefore, x= 45 and y also = 45.

Now that there are 2 right angles, that makes up 180. 180+49=229

A full rotation is 360, so you subtract that. 360-229=131
z=131.

Answer:

x = 41°y = 49°z = 131°

Step-by-step explanation:

The relevant relations are ...

a straight angle measures 180°a right angle measures 90°vertical angles have the same measure

The angle marked 49° and the one marked "y" are vertical angles, so have the same measure.

y = 49°

The angle marked "x" and the angle marked "y" together make up a right angle, so total 90°.

x + y = 90°

x + 49° = 90°

x = 41° . . . . . . . . . subtract 49°

The angle marked z and the one marked 49° together make up a straight angle, so total 180°. (They are a "linear pair.")

49° +z = 180°

z = 131° . . . . . . . subtract 49°

The measures of the marked angles are ...

x = 41°

y = 49°

z = 131°

Answers

Answer: m ≥ 1,379

Step-by-step explanation:

$26 monthly fee

$0.06/minute of use

$108.74 (least charged in a month)

m = number of minutes

26 + 0.06m ≥ 108.74

0.06m ≥ 108.74 - 26

0.06m ≥ 82.74

[tex]\frac{0.06m}{0.06}[/tex] ≥ [tex]\frac{82.74}{0.06}[/tex]

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, we want a function with a slope of 5(rate of change), and an y-intercept of 10(initial quantity), hence option C is correct.

What is the surface area for a rectangular prism with the height of 6 inches, width of 8 inches, and the length of 4 inches

Answers

Answer:

Using the formula, we can find that the surface area is 208 in².

Step-by-step explanation:

To find the surface area (SA) for a rectangular prism, substitute its dimensions into the formula and solve.

Dimensions

Dimensions mean the side lengths of the shape, the height, width and length. We know the dimensions from the question.

Height: h = 6 in

Width: w = 8 in

Length: l = 4 in

Formula

We will need the formula to find the surface area for rectangular prisms. Note that different shapes have a different formula for finding surface area.

[tex]SA= 2(lw + lh + hw)[/tex]

Substitute the dimensions h = 6in, w = 8in and l = 4in into the formula.

[tex]SA= 2((4\ in)(8\ in) + (4\ in)(6\ in) + (6\ in)(8\ in))[/tex]

[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Question:-}}}}[/tex]

The quotient of b and 3 is greater than or equal to 19.

[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}[/tex]

✥First, the word "quotient" indicates that we divide.

Here we have "the quotient of b and 3", so we divide b by 3:-

[tex]\hookrightarrow[/tex][tex]\sf{b\div3}[/tex]

Now, this expression is greater than or equal to 19:-

[tex]\sf{b\div3\geq 19}[/tex]

How to Solve for b

✳︎ Multiply by 3 on both sides:-

[tex]\sf{b\geq 19\times3}[/tex]

On simplification,

[tex]\sf{b\geq 57}[/tex]

So the values of b greater than or equal to 57 will make this inequality true.

Let's solve another one.

✳︎ A number y increased by 5 is at least -21.

First, "increased" means we add 5.

Since y is increased by 5, we add 5 to y:-

[tex]y+5[/tex]

Now this expression is at least -21, which means it can't be less than -21, thus, it's greater than or equal to -21, which looks as follows:-

[tex]\sf{y+5 \geq -21}[/tex]

[tex]\rule{300}{1}[/tex]

[Solving for y]

Subtract 5 on both sides:-

[tex]\sf{y \geq -21-5}[/tex]

On simplification,

[tex]\sf{y \geq -26}[/tex]

So the values of y greater than or equal to -26 will make this inequality true.

Good luck with your studies.

The scale factor of the dilation of triangle def is three-tenths i.e. 3/10

How to determine the scale factor of dilation?

From the complete question, the corresponding sides are:

DE = 10

D'E' = 3

The scale factor k is then calculated using"

DE * k = D'E'

So, we have:

10* k = 3

Divide both sides by 10

k = 3/10

The probability that a person selected at random is Ages 16-18 and has prepared a meal for their family

How to determine the experimental probability?

From the table of values, we have:

Age 16 - 18 that has performed meal = 8

Total = 30

The probability is then calculated using:

P(16 - 18) = n(16 - 18)/Total

This gives

P(16 - 18) = 8/30

Simplify

P(16 - 18) = 4/15

Hence, the probability is 4/15
