Step-by-step explanation:

because the sum of the angles of a triangle should = 180, and adding these numbers together give  a greater result of 220 degrees

Answer:

All the numbers are technically, rational.

Step-by-step explanation:

Step-by-step explanation:

this is really simple : we only need to put the given x and y coordinate values into both equations and see, if both equations remain true.

(-2, -1) means x = -2, y = -1

first equation :

-1 = 3×-2 + 5 = -6 + 5 = -1

so, -1 = -1

true.

second equation :

-2 + -1 = -3

-3 = -3

true.

therefore, (-2, -1) is a solution to the linear system.

the point is the crossing point of both lines.

Answer:

(a) AA Similarity using alternate interior angles

(b) 6.3

Step-by-step explanation:

(a)

Triangles ABD and BDC have a given pair of congruent angles, angles ABD and BCD.

With parallel lines AB and DC and transversal BD, then alternate interior angles ABD and BDC are congruent.

Now we have two pairs of congruent corresponding angles, so by AA Similarity, triangles ABD and BDC are similar.

(b)

Triangles ABD and BDC are similar.

The ratios of the lengths of corresponding sides are equal.

AB/BD = AD/BC

4/6 = 4.2/BC

4BC = 6 × 4.2

BC = 6.3

Answer:

A = 2298.48

Step-by-step explanation:

The right triangle with the 35angle. you need to find the height of that triangle which is the adjacent side and the opposite side is 44

tan 35° = opposite/ adjacent

[tex]tan 35 = \frac{44}{x}[/tex]

[tex]tan 35(x) = 44[/tex]

[tex]x = \frac{44}{tan 35}[/tex]

x = 62.83  ≈ 62.8

Using the 25° angle, you have the height which is 62.8 and looking for the side opposite the 25° angle.

So  tan 23° = x/adjacent side

[tex]tan 25= \frac{x}{62.8}[/tex]

[tex]tan 25(62.8)= x[/tex]

29.28 ≈29.2                A = 1/2bh ;  A = 1/2 (44 + 29.2)(62.8) ;  A = 2298.48

Answer:

119

Step-by-step explanation:

Angle ABD and angle DBC are supplementary so their sum is equal to 180

therefore to find the measure of ABD we subtract 61 from 180

<ABD = 180 - 61

<ABD = 119

Step-by-step explanation:

Q.2. 12 men are building a wall which is 8 m long, 6 m high and 22.5 cm thick using bricks. On this basis answer the following.

i. Find the volume of the cuboidal wall.

Substituting all the given values in the formula to find volume of cuboidal wall :

[tex] \begin{gathered}\qquad{\longrightarrow{\sf{V = LBH}}} \\ \\ \qquad{\longrightarrow{\sf{V = L \times B \times H}}} \\ \\ \qquad{\longrightarrow{\sf{V = 800 \times 600 \times 22.5}}} \\ \\ \qquad{\longrightarrow{\sf{V = 480000 \times 22.5}}} \\ \\ \qquad{\longrightarrow{\sf{\underline{\underline{\red{V = 1,08,00,000 \: {cm}^{3}}}}}}} \end{gathered}[/tex]

Hence, the volume of cuboidal wall is 1,08,00,000 cm³.

———————————————————————

ii. If the dimension of each brick is 25 cm × 11.25 cm × 6 cm, then find the volume of the brick.

Substituting all the given values in the formula to find the volume of cuboidal brick :

[tex] \begin{gathered}\qquad{\longrightarrow{\sf{V = LBH}}} \\ \\ \qquad{\longrightarrow{\sf{V = L \times B \times H}}} \\ \\ \qquad{\longrightarrow{\sf{V = 25 \times 11.25\times 6}}} \\ \\ \qquad{\longrightarrow{\sf{V = 281.25\times 6}}} \\ \\ \qquad{\longrightarrow{\sf{\underline{\underline{\pink{V = 1687.5 \: {cm}^{3}}}}}}} \end{gathered}[/tex]

Hence, the volume of cuboidal brick is 1687.5 cm³.

————————————————————

iii. How many bricks will be required to construct the cuboidal wall.

Substituting all the given values in the formula to find the number of bricks :

[tex] \begin{gathered} \quad{\longrightarrow{\sf{No. \: of \: bricks = \dfrac{Volume \:of \: wall}{Volume \: of \: brick}}}}\\ \\ \quad{\longrightarrow\sf{No.\: of \: bricks = \dfrac{10800000}{1687.5}}} \\ \\ \quad{\longrightarrow{\sf{No. \: of \: bricks = \cancel{\dfrac{10800000}{1687.5}}}}} \\ \\ \quad{\longrightarrow{\sf{\underline{\underline{\purple{No. \: of \: bricks = 6400}}}}}}\end{gathered}[/tex]

Hence, 6400 bricks will be required to construct the cuboidal wall.

75% can also be written as 0.75 so

116×0.75 is 87

To compare the shapes of the distributions from the experiments, a z-test can be used.

Your information is incomplete as the distributions aren't given. Therefore, an overview will be given. It should be noted that a z-test is a statistical test that's us used to determine if the means of two population are different when their variances are known.

Z-tests simply test the mean of a distribution. To compare the distributions, the error in the mean will be calculated by dividing the dispersion by the square root of the number of data points.

Answer:

2 feet times nine equals 18

well, the price difference is 60000 - 40000 = 20000.

so, we're told that the price increase acres wise is 800 bucks per acre, but we also know it's a total of 20000, so how may times does 800 go into 20000?

20000 ÷ 800 = 25.

so we know that in 20000 bucks there are 25 acres, so how many will there be in 60000 bucks?

[tex]\begin{array}{ccll} \$&acres\\ \cline{1-2} 20000&25\\ 60000&x \end{array}\implies \cfrac{20000}{60000}=\cfrac{25}{x}\implies \cfrac{1}{3}=\cfrac{25}{x}\implies \stackrel{acres}{x=75}[/tex]

Answer:

k=2

Step-by-step explanation:

Expanding gives

[tex]3k-4k+8=14k-22[/tex].

Further simplification yields

[tex]-k+8=14k-22[/tex]

[tex]15k=30[/tex]

[tex]k=2[/tex].

Step-by-step explanation:

Use the Distributive Property:

[tex]3k - 4k + 8 = 14k - 22[/tex]

[tex] - k + 8 = 14k - 22[/tex]

Add k to both sides:

[tex]8 = 15k - 22[/tex]

Add 22 to both sides:

[tex]30 = 15k[/tex]

Divide each side by 15:

[tex]2 = k[/tex]
