help find the missing number for x

Answer:

Opción b, P(2) = 0

Step-by-step explanation:

Tenemos la expresión:

P(y) = y^2 - 7*y + 10

Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:

P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0

P(2) = 0

La opción correcta es b.

Answer: 90.75 mm

Step-by-step explanation:

Given

The radius of the hemisphere is 16 mm

length of the inclined sides are 20 mm

The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference

[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

Answer:

Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = 2,000 miles

Step-by-step explanation:

Time taken for Train W to complete a trip = 20 hours

Time taken for Train Z to complete a trip = 25 hours

The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.

both trains have same speeds and start from same location.

To find the distance in total each train travels.

Solution:

Let length of the trip of Train W be = xx miles

Speed of Train W can be given as :

⇒ \frac{Distance}{Time}

Time

Distance

⇒ \frac{x}{20}\ miles/h

20

x

miles/h

So, the length of the trip of Train Z will be = (x+400)(x+400) miles

Speed of Train Z can be given as :

⇒ \frac{Distance}{Time}

Time

Distance

⇒ \frac{x+400}{25}\ miles/h

25

x+400

miles/h

Since the speeds are same, so the equation to find xx can be given as:

⇒ \frac{x}{20}=\frac{x+400}{25}

20

x

=

25

x+400

Solving for xx

Multiplying both sides by 100 to remove fractions.

⇒ 100\times \frac{x}{20}=100\times \frac{x+400}{25}100×

20

x

=100×

25

x+400

⇒ 5x=4(x+400)5x=4(x+400)

Using distribution.

⇒ 5x=4x+16005x=4x+1600

Subtracting both sides by 4x4x

⇒ 5x-4x=4x-4x+16005x−4x=4x−4x+1600

⇒ x=1600x=1600

Thus, Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = 1600+4001600+400 = 2,000 miles

Answer:

Solution given:

5.

we have.

11x=½(16x+16+50)

22x=16x+66

22x-16x=66

6x=66

x=66/6

x=11

6.

118°=½(6x-11+181)

236=6x+170

6x=236-170

x=66/6

x=11°

Answer:

There are 45 boys in the gym class.

Step-by-step explanation:

Set up an equation:

Variable x = number of boys in the class

5/3 = x/27

Cross multiply:

5 × 27 = 3 × x

135 = 3x

Divide both sides by 3

45 = x

Check your work:

5/3 = 45/27

5 × 27 = 3 × 45

135 = 135

Correct!

Answer:

See a sides are equal so your answer is 8.2 in.

Answer:

10$

Step-by-step explanation:

Answer:

$10

Step-by-step explanation:

Honestly, who eats that much fruit? but okay, we'll start with finding how much money she spent, and apples will go first:

So this is basically dealing with rates, so you just gotta multiply:

5 x 5 = 25

So you spent an unnecessary $25 on apples, now let's go to pears:

3 x 5 = 15

So you spent $15 on pears, now we combine those two:

25 + 15 = 40

So you spent $40 on fruit

So now we want to know how much money we have left, so we're gonna subtract:

50 - 40 = 10

So you have $10 left over

hope this helps:)

Answer:

A is correct

Step-by-step explanation:

Mathematically from logarithmic laws, we have it that;

x log a = log a^x

and also;

log a - log b = log (a/b)

So we have;

log 5 10^3 - log 5 7^12

and finally log 5 (10^3/7^12)

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.
