Answer: false

Step-by-step explanation:  Compare -5 and -32. They do not equal each other.

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]

[tex]\bold{\huge{\pink{\underline{ Solution }}}}[/tex]

We have given in the question that,

[tex]\bold{\underline{ To \: Find }}[/tex]

[tex]\bold{\underline{ Let's \: Begin }}[/tex]

Let the two numbers be x and y

According to the question,

[tex]\sf{ x + y = 11......eq(1) }[/tex]

[tex]\sf{ x - y = 19......eq(2) }[/tex]

Solving eq( 1 ) we get :-

[tex]\sf{ x + y = 11 }[/tex]

[tex]\sf{ x = 11 - y ......eq(3 ) }[/tex]

Subsituting eq(3 ) in eq(2) :-

[tex]\sf{ x - y = 19 }[/tex]

[tex]\sf{ ( 11 - y) - y = 19 }[/tex]

[tex]\sf{ 11 - y - y = 19 }[/tex]

[tex]\sf{ 11 - 2y = 19 }[/tex]

[tex]\sf{ - 2y = 19 - 11 }[/tex]

[tex]\sf{ - 2y = 8}[/tex]

[tex]\sf{ y = 8/(-2) }[/tex]

[tex]\sf{ y = - 4 }[/tex]

[tex]\sf{\red{Thus ,\: the\: value\: of \: y = -4}}[/tex]

Now, Subsitute the value of y in eq( 3 ) :-

[tex]\sf{ x = 11 - y }[/tex]

[tex]\sf{ x = 11 - (-4 ) }[/tex]

[tex]\sf{ x = 11 + 4 }[/tex]

[tex]\sf{ x = 15 }[/tex]

Hence, The value of x and y are 15 and (-4) .

Add up to get the total number of marbles: (8 + 6 + 12 + 10) = 36

Then subtract the number of blue marbles from the total amount of marbles: 36 - 8 = 28.

28 signifies the amount of marbles that are NOT blue.

So the probability is: 28/36 = 0.77 = About 77%

The final answer is 7/9.

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]

Step-by-step explanation:

Because 14 is - 4 you multiple to 5 equal= dhi2

An interior angle of a polygon is found by subtracting 2 from the number of sides, multiplying that by 180 And then divide by the number of sides:

40-2 = 38

38 x 180 = 6840

6840/40 = 171

Answer : 171 degrees

Answer:

48 meters

Step-by-step explanation:

Shorter leg will be the side opposite to the angle measuring 30°. Using sin trigonometric ratio the length of hypotenuse can easily be obtained.

[tex] \sin 30 \degree = \frac{length \: of \: shorter \: leg}{length \: of \: hypotenuse} \\ \\ \implies \: \frac{1}{2} = \frac{24}{l(hypotenuse)} \\ \\ \implies \: {l(hypotenuse)} =2 \times 24 \\ \\ \implies \: {l(hypotenuse)} =48 \: m[/tex]

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:

3.25/5*9= 5.85

Step-by-step explanation:

3.25euros divided by 5pens times 9pens= 5.85euros

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:

there are 12 boys because 32/8 =4 and the ratiots 3 to 8 which means you need to multiply 3 by 4 which gives you 12

Step-by-step explanation:

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:

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

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
