Hope this helps!

Answer:

(5,6) , (5,-2)

Step-by-step explanation:

Let the required point be P(5,y).

Its distance from (2,2) is 5 units.

So, [tex](5-2)^{2}[/tex] + [tex](y-2)^{2}[/tex] = 25.

So, [tex]3^{2}[/tex] +  [tex](y-2)^{2}[/tex] = 25.

  9 +  [tex](y-2)^{2}[/tex] = 25.

   [tex](y-2)^{2}[/tex] = 16

    Two cases are possible for now

case 1 : y-2 = 4 .

            y = 6

required point will be (5,6)

case 2 : y - 2 = -4.

              y = -2.

required point will be (5,-2).

Two points are possible : (5,6) , (5,-2).

The solution of the given proportionality is x = 603

The given proportionality is,

2/67 = 18/x

Since we know that,

Proportion is mostly discussed using ratios and fractions. A fraction is written as a/b, whereas a ratio is expressed as a:b, and a percentage says that two ratios are equal.

In this case, a and b can be any two numbers. The ratio and proportion are important foundations for understanding numerous ideas in mathematics and science.

Now proceeding the expression,

⇒ 18/x = 2/67

Taking reciprocal both sides we get,

⇒ x/18 = 67/2

Multiply 18 both sides we get,

⇒ x = (67x18)/2

      =  67x9

      = 603

Hence,

x = 603

Harrison's prediction that the actual quotient for 57872 divided by 305 would be less than his estimate of 200 is correct. This is because the divisor (305) is larger than in the estimate (300), and also because the dividend (57872) is smaller than in the estimate (60000), leading to a smaller quotient.

Harrison predicted that the actual quotient for 57872 divided by 305 would be less than his estimate of 60,000 divided by 300 which equals 200. To understand Harrison's prediction, we have to look at the numbers involved. When you are dividing two numbers, the quotient decreases as the divisor (the number you are dividing by) increases, given that the dividend (the number being divided) remains the same. In this case, 305 is larger than 300, so if the dividend were the same, the quotient for our original problem would indeed be smaller. However, the dividend in our original problem (57872) is smaller than the dividend in the estimate (60000). So we have a smaller number being divided by a slightly larger one, and this will also lead to a smaller quotient. Therefore, Harrison's prediction is correct.

Answer:

The segment GT is a median of triangle GFH

Step-by-step explanation:

we know that

A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side.

The angle bisector of a triangle is a line segment that bisects one of the vertex angles of a triangle.

In this problem

SH represent a line segment that bisects the vertex angle H of triangle GFH, so represent an angle bisector.

GT represent a median of triangle GFH, because the point T is the midpoint  of segment FH (FT=TH)

therefore

The segment GT is a median of triangle GFH

Answer:

c. 106 million

Step-by-step explanation:

A = number of people in the sample that use public transportation 5 or more days per week

A = 2,067,153

B = number of people total in the sample

B = 4,295,280

C = proportion of those in the sample that use public transportation 5 or more days per week

C = A/B

C = (2,067,153)/(4,295,280)

C = 0.48126 approximately

Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week

C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million

Answer:

a= 151.87 units

Step-by-step explanation:

Given:

Consider,a right triangle Δ ACB with Angle C as 90°,

and side a, b, and c be the sides opposites to the respective angles. Such that

c = Hypotenuse = 155

b = Shorter leg = 31

a = Longer leg  = ?

To Find:

a = Longer leg  = ?

Solution:

In Right angle Δ ACB

If we apply Pythagoras Theorem we get

[tex](\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}[/tex]

Now substituting the given above values we get,

[tex]c^{2}= b^{2} + a^{2}\\x^{2}  155^{2}= 31^{2}+ a^{2}\\ 24025=961+a^{2}\\\therefore a^{2}=24025-961\\a^{2} = 23064\\ a=\pm 151.8683\\\therefore a = 151.87 .......\textrm{Distance cannot be in negative}[/tex]

∴ a= 151.87 units......(rounded to nearest hundredth)

Answer:

The corresponding pair of sides are in the same ratio.

Step-by-step explanation:

For two triangles to be similar, the theorem that is required is the corresponding sides of the two triangles are in the same ratio.

Now, see the diagram of two triangles given with the question.

The ratios of the corresponding sides are [tex]\frac{20}{16} = \frac{19}{\frac{76}{5} } = \frac{5}{4}[/tex]

If two pairs corresponding sides are in 5 : 4 ratio, then the third pair of corresponding sides will also be in 5 : 4 ratio.

Therefore, the two triangles are similar. (Answer)

To prove that two triangles are similar, you can use the AA (Angle-Angle) Postulate, SSS (Side-Side-Side) Similarity Theorem, or SAS (Side-Angle-Side) Similarity Theorem. These methods involve comparing the angles and sides of the triangles to see if they meet the similarity conditions.

Triangle Similarity Theorem

To determine whether two triangles are similar, you can use several different theorems or postulates. These include the AA (Angle-Angle) Postulate, the SSS (Side-Side-Side) Similarity Theorem, and the SAS (Side-Angle-Side) Similarity Theorem.

AA (Angle-Angle) Postulate: If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.

SSS (Side-Side-Side) Similarity Theorem: If the three sides of one triangle are proportional to the three corresponding sides of another triangle, then the triangles are similar. For example, if triangle ABC and triangle DEF have corresponding sides such that AB/DE = BC/EF = AC/DF, then the triangles are similar.

SAS (Side-Angle-Side) Similarity Theorem: If an angle of one triangle is congruent to an angle of another triangle and the sides containing these angles are proportional, then the triangles are similar. For example, if ∠A = ∠D and AB/DE = AC/DF, then triangles ABC and DEF are similar.

By using these theorems, you can determine if two triangles are similar by comparing their angles and sides as per the given conditions.

For this case we have that by definition, the distance between two points is given by:

[tex]d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}[/tex]

We have to:

[tex](x_ {1}, y_ {1}): (4, -1)\\(x_ {2}, y_ {2}): (7,5)[/tex]

Substituting:

[tex]d = \sqrt {(7-4) ^ 2 + (5 - (- 1)) ^ 2}\\d = \sqrt {(7-4) ^ 2 + (5 + 1) ^ 2}\\d = \sqrt {(3) ^ 2 + (6) ^ 2}\\d = \sqrt {9 + 36}\\d = \sqrt {45}\\d = 6,708[/tex]

We round:

[tex]d = 6.7[/tex]

Step-by-step explanation:

Answer:

The amount invested in the mutual fund that earned 5% was $1,000

The amount invested in the mutual fund that earned 3% was $1,800

Step-by-step explanation:

Let

x ----> the amount invested in the mutual fund that earned 5%

y ----> the amount invested in the mutual fund that earned 3%

we know that

[tex]x+y=2,800[/tex] ----> [tex]y=2,800-x[/tex] ----> equation A

[tex]5\%=5/100=0.05[/tex]

[tex]3\%=3/100=0.03[/tex]

[tex]0.05x+0.03y=104[/tex] ----> equation B

Solve the system by substitution

substitute equation A in equation B

[tex]0.05x+0.03(2,800-x)=104[/tex]

Solve for x

[tex]0.05x+84-0.03x=104[/tex]

[tex]0.05x-0.03x=104-84[/tex]

[tex]0.02x=20[/tex]

[tex]x=\$1,000[/tex]

Find the value of y

[tex]y=2,800-x[/tex]

[tex]y=2,800-1,000=\$1,800[/tex]

therefore

The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800

Answer:

x = 15

Step-by-step explanation:

If ZABC = 130º

ZABC = (6x+40)°​ = 130º

This equation can be rearranged to solve for x by isolating it (moving everything over to the other side).

(6x+40)°​ = 130º

Solve it without the degrees sign because it looks confusing.

6x+40 = 130

6x+40 - 40 = 130 - 40   (subtract 40 from both sides)

6x = 90

6x/6 = 90/6    (divide both sides by 6)

x = 15

Therefore x is 15. The degrees symbol is already included outside the bracket.

Answer:

The length of river frontage for each lot are 96.55 ft. 98.85 ft, 101.15 ft and 103.45 ft.

Step-by-step explanation:

See the attached diagram.

The river frontage of 400 ft will be divided into 84 : 86 : 88 : 90 for each lot as AP, BQ, CR, DS and ET all are parallel.

Therefore, PQ : QR : RS : ST = 84 : 86 : 88 : 90 = 42 : 43 : 44 : 45

Let, PQ = 42x, QR = 43x, RS = 44x and ST = 45x

So, (42x + 43x + 44x + 45x) = 400

⇒ 175x = 400

⇒ x = 2.2988.

So, PQ = 42x = 96.55 ft.

QR = 43x = 98.85 ft.

RS = 44x = 101.15 ft and  

ST = 45x = 103.45 ft
