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:

The area of the room is 37.5 square inches.

Step-by-step explanation:

Consider that the room is rectangular in shape.

The dimensions of the rooms are:

Length (l) = 7.5 inches

Breadth (b) = 5 inches

The area of a rectangle is:

Area = l × b

Compute the area of the room as follows:

Area = l × b

        [tex]=7.5\times 5\\=37.5[/tex]

Thus, the area of the room is 37.5 square inches.

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:

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

Answer: She scan products at

Given that: A grocery store clerk can scan one product every 1/2 of a second.

That means:

Rate = 2 per second.

Rate = (2*60) = 120 per minute.

Rate = (120*60) = 7200 per hour

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:

24 ml oil

60 g onions

360 g potatoes

400 ml milk

Step-by-step explanation:

The recipe makes 16 portions and you only need 4 portions. Since 16 is 4 times bigger than what you need, just divide everything you've been given by 4.

*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.

1) 96/4 = 24 ml

2) 240/4 = 60 g

3) 1.44/4 = 0.36 kg

They want it in grams, so times it by 1,000 to convert. this gives you 360 g.

4) 1.6/4 = 0.4 l

They want it in ml, so times it by 1,000 to convert. this gives you 400 ml.

Answer:

a = 125°, b = 20°, c = 35°, d = 90°, e = 55°

Step-by-step explanation:

Quadrilateral PQRS is inscribed in a circle, therefore it is a cyclic quadrilateral.

PQ is diameter, SR is chord and PR is transversal such that:

PQ || SR... (given)

[tex] m\angle PRQ = 90°..(\angle \: inscribed \: in\: semicircle) \\

\huge \red {\boxed {\therefore d = 90°}} \\\\

m\angle RPQ= m\angle PRS .. (alternate \: \angle s) \\

\huge \purple {\boxed {\therefore c = 35°}} \\\\

In\: \triangle PQR, \\

c + d + e = 180°\\

35° + 90° + e = 180°\\

125° + e = 180°\\

e = 180° - 125°\\

\huge \orange {\boxed {\therefore e = 55°}} \\\\

a + e = 180°...(opposite \:\angle 's \: of \: cyclic \: quadrilateral) \\

a + 55°= 180°\\

a = 180°- 55°\\

\huge \blue {\boxed {a = 125°}} \\\\

In\: \triangle PSR, \\

a + b + 35°= 180°\\

125° + b + 35° = 180°\\

160° + b = 180°\\

b = 180° - 160°\\

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:

The triple is 9, 12, 15

The hypotenuse is 15.

Step-by-step explanation:

Pythagorean Theorem Formula: a²+b²=c² where a & b are the short legs and c is the hypotenuse.

9²+b²=(b+3)²

81+b²=(b+3)²

Small list of the Pythagorean Triples that contain 9:

9,12,15

9,40,41

So as you can see, there are only 2 examples in my list that contain 9 in them. The only one that fits our criteria is the triple, 9, 12 and, 15

You don't need to use the Pythagorean Formula for this as I have just proved.

Answer:

12 cm

Step-by-step explanation:

I don't think u have to use the phytagores theorem b/c the hypotenuse is 9+3=12. but if u have to use this.

[tex] {?a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {9}^{2} + {b}^{2} = {9 + 3}^{2} [/tex]

[tex]81 + {b}^{2} = 9(9 + 3) + 3(9 + 3)[/tex]

[tex]81 + {b}^{2} = 81 + 54 + 9[/tex]

[tex]81 + {b}^{2} = 144[/tex]

[tex] {b}^{2} = 144 - 81 = 63[/tex]

[tex] {b}^{2} = \sqrt{53} = b = 7.93[/tex]

so if u found b then u can find c by using the same formula.

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {9}^{2} + {7.93}^{2} = {c}^{2} [/tex]

[tex]81 + 63 = {c}^{2} [/tex]

[tex] {c}^{2} = 81 + 63 = 144[/tex]

[tex] \sqrt{c} = \sqrt{144} [/tex]

[tex]c = 12[/tex]

Answer:

36 like iphone only

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.
