Answer:

26

Step-by-step explanation:

10 x 4 = 40

6.5 x 4 = 26

The height of the telephone pole is 26 foot.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Shadow of 6.5 foot street sign = 10 foot

Let the height of telephone pole = h foot

According to given condition,

Shadow of h foot telephone pole = 40 foot

Since, 10 foot shadow cast by 6.5 foot street sign

To find the height of the pole,

Use Ratio property,

10/6.5=40/h

⇒h=26 foot

The height of telephone pole is 26 foot

Answer:

A. and D. are correct

Step-by-step explanation:

The correct answers are Option A, Option D.

The terms which have the GCF of [tex]6x^3\\[/tex] are [tex]12p^3r[/tex] and [tex]54p^3[/tex].

Given data:

To find the greatest common factor (GCF) of the given terms, we need to find the highest power of x that divides into all the terms and the highest power of p that divides into all the terms.

For [tex]12p^3r[/tex] , the highest power of x that divides into this term is [tex]x^0[/tex](since x^0 = 1), and the highest power of p that divides into this term is [tex]p^3[/tex]. Therefore, the GCF is [tex]1 * p^3 = p^3.[/tex]

For 54p^3, the highest power of x that divides into this term is [tex]x^0[/tex] (since x^0 = 1), and the highest power of p that divides into this term is [tex]p^3[/tex]. Therefore, the GCF is [tex]1 * p^3 = p^3.[/tex]

Hence, the terms are [tex]12p^3r[/tex] and [tex]54p^3[/tex].

Answer:

Tiffany made the better buy

Step-by-step explanation:

Based on the information provided within the question it can be said that Tiffany made the better buy in this scenario. Mainly because Tiffany paid a less amount per pound than Tony did. This can be calculated by dividing the total amount each paid by the total amount each of them received, like so...

Tiffany: $38 / 9 = $4.22 per pound

Tony: $19 / 3 = $6.33 per pound

Therefore we can see that Tiffany paid $4.22 per pound and Tony paid $6.33 per pound a whole $2.11 more than Tiffany, thus making Tiffany purchase the better buy.

Answer:

t = 6 days

Step-by-step explanation:

We can model both cases with linear equations in the form:

y = ax + b

Sophie was on page 20 and she reads 10 pages per day, so her equation is:

S = 20 + 10t

Jackson was on page 50 and he reads 5 pages per day, so his equation is:

J = 50 + 5*t

The graph of those equations are in the image attached (The blue line is for Sophie and the orange line is for Jackson)

To find after how many days they will be on the same page, we can make S = J and then find the value of t:

20 + 10t = 50 + 5t

5t = 30

t = 6 days

Answer:

Correct option: B -> 36

Step-by-step explanation:

The surface area of a circular cone is given by the formula:

Surface area = pi * radius * (radius + slant height)

If the inicial radius is 4 in and the slant height is 9 in, we have:

Surface area = pi * 4 * (4 + 9) = 52pi in2

The radius and the slant height are multiplied by 6, so we have:

radius = 6 * 4 = 24 in

slant height = 6 * 9 = 54 in

So the new surface area is:

New surface area = pi * 24 * (24 + 54) = 1872pi in2

The factor of the surface areas is:

New surface area / Surface area = 1872pi / 52pi = 36

Correct option: B

The above highlight show that one side and one angle of the triangle are congruent

To complete the AAS postulate, one other corresponding angle must be congruent.

From the figure, points A and D are corresponding points

Hence, to show that ABC =DEF by AAS congruent postulate, (A) [tex]\angle A \cong \angle D[/tex] must be true

The reason needs to show the triangles are congruent by AAS is ∠A ≅ ∠D.

Two triangles are said to be congruent if their corresponding parts are congruent with each other.

Given that, triangles ΔABC, and ΔDEF, need to be congruent by AAS rule,

∠C ≅ ∠F, AB = DE, we need to find one more reason,

AAS rule :-

AAS or Angle Angle Side congruence rule states that if two pairs of corresponding angles along with the opposite or non-included sides are equal to each other then the two triangles are said to be congruent.

So, the reason must be  ∠A ≅ ∠D.

Hence, the reason needs to show the triangles are congruent by AAS is ∠A ≅ ∠D.

Answer:

y=1/2x+5

Step-by-step explanation:

the perpendicular line equation's slope is a negative reciprocal, so the new equation's slope is 1/2. so now you have y=1/2x+b plug in (-4,3) to find b. so you will do 3=1/2(-4)+b. 3=-2+b and then you solve for b. you would get b=5. so, the new equation is y=1/2x+5

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Randomly surveying 6th graders in the school cafeteria would give jacob valid results because A wouldn't be reliable, because he just wants 6th graders, and B and D would be selective as it would be inside a football store, implying that most 6th graders in there would be tending towards football, and D would be inside a tennis shop, which would imply that most 6th graders there would prefer football. Therefore, the cafeteria would yield the most reliable results.

Answer:

144m^3

Step-by-step explanation:

The solution for equation is at (-2, 0).

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

Both linear equations with one variable and those with two variables exist.

Given equations,

y = x + 2

y = x² + 5x + 6

substitute value of y in second equation

x + 2 = x² + 5x + 6

x² + 4x + 4 = 0

x² + 2x + 2x +4 = 0

x(x +2) + 2(x + 2) = 0

(x + 2)(x + 2) = 0

x = -2

and y = x + 2

y = -2 + 2 = 0

Hence, the solution of equation is at x  = -2 and y = 0.

Answer:

28.5 ft

Step-by-step explanation:

The height of a ball is given by the equation ƒ(x) = −16x² + 45x + 2.5 where x is the tome the ball travels. To find the height of the ball after a seconds, we substitute a in place of x, the equation becomes:

ƒ(a) = −16a² + 45a + 2.5.

Therefore if the height of the ball is needed to be found after 2 seconds, we find f(2).

ƒ(2) = −16(2)² + 45(2) + 2.5 = -64 + 90 + 2.5 = 28.5 ft

f(2) = 28.5 ft

Step-by-step explanation:

You know that 40 people like both so you can already get them out of the way. That leaves you with 60 people and if we are dividing them into 5ths then 1/5 = 12 people. If the ratio is 3:2 then you can just multiply 3 x 12 to get 36 and then 2 x 12 to get 24 and that equals 60 and added to your 40 who like both, you get 100 students.

The equation 890 = 1/3 B(46)  can be used to find the area of the circular base .

Area is the space enclosed  within the perimeter of the given shape.

It is given in the question that Area of the base of a volcano has to be determined.

The structure of a volcano is that of a Cone

Area of a conical structure is given by

V = (1/3) * height * (radius)²

890 = 1/3 (radius)²(46)

V = 890 h = 46

area of a circle = π (radius)²,

890 = 1/3 B(46)
