2x-7=-3x9 what value of x would make this equation true

Answer:

0.4643

Step-by-step explanation:

z = (x-μ) / σ, donde

x es la puntuación bruta = 70.3 pulgadas

μ es la media de la población = 69 pulgadas

σ es la desviación estándar de la población = 2.8 pulgadas

z = (70.3 - 69) /2.8

z = 0.46429

Aproximadamente a 4 lugares decimales = 0.4643

Answer:

P=2500(1+0.25)

Step-by-step explanation:

Given  data

Initial population= 2500

Rate= 25%

The exponential increase is described using the expression

P=A(1+r)^t

Hence the correct representation is

P=2500(1+0.25)

Answer:

x=5 y=-6

Step-by-step explanation:

3x+y=9 ------eqn1

y=4-2x -------eqn2

using substitution

put y=4-2x into eqn1

3x+4-2x=9

x=5

put x=5 into eqn2

y=4-2(5)

y=4-10

y=-6

Answer:

9

Step-by-step explanation:

To be a composite number, it has to be divisible by something other than 1 and itself.

5, 2, and 11 are all prime numbers, meaning their only factors are 1 and itself.

9 is composite, as it can be multiplied by 1•9 OR 3•3. Since it can be multiplied by something other than 1 and itself (aka the 3 is a factor) is is composite.

Step-by-step explanation:

9 is the composite number

Answer:

∠PTQ = 124°

Step-by-step explanation:

∠QPT = 90° - 62° = 28°

∠PQT = 28°

∠PTQ = 180° - 28° - 28° = 124°

Answer:

45

Step-by-step explanation:

2.5 x 12= 30

1/2 (6) (3)= 9

1/2( 2) (6)=6

30 +9 +6 = 45

Answer:

Step-by-step explanation:

This is a direct proportionality. If a water spout is filling a large container with water, hence the time taken to fill the container is directly proportional to the volume v of water. MAthematically;

t = kV

If after 5 hours the container held 24L of water, then;

5 = 24k

k = 5/24

Also if after 8 hours the container held 30L of water

8 = 30k

k = 8/30

To get the rate of the container at 2 hrs

There are 3.5 gram of peanuts in a bag for every 1 gram of raisin  

An equation is an expression that shows the relationship between two or more numbers and variables.

From the table:

14 g of peanut = 4 gram of raisins

Hence:

1 gram of raisin = (14/4) = 3.5 gram of peanuts

Answer:

$70.00

Step-by-step explanation:

Percentage of original price paid

= 100% -30%

= 70%

70% of original price ----- $49.00

1% of original price ----- $49.00 ÷70= $0.70

100% of original price ----- $0.70 ×100= $70.00

Answer:

The volume of the silo is approximately  147,026.6 ft.³.

The most correct option is  147,026.5 ft.³

Step-by-step explanation:

The given dimensions of the silo are;

The shape of the silo = Composite figure of tower and roof

The shape of the tower = Cylindrical

The shape of the roof = Cone

The radius of the base of the silo, 'r' = 30 feet

The height of the cone roof of the silo, h₁ = 12 feet

The height of the entire silo = 60 feet

For the cone roof, we have;

The volume of a cone, V = 1/3 × Base area × Height

The volume of the cone roof, V₁ = 1/3×π·r² × h₁

∴ V₁ = 1/3 × π × (30 ft.)² × 12 ft. ≈ 11,309.7336 ft.³

For the cylindrical tower, we have;

The height of the entire silo = The height of the tower + The height of the roof

∴ The height of the tower = The height of the entire silo - The height of the roof

The height of the tower, h₂ = 60 ft. - 12 ft. = 48 ft.

The volume of a cylinder = Area of base × Height

The volume of the cylindrical tower, V₂ = π·r² × h₂

∴ V₂ = π × (30 ft.)² × 48 ft. ≈ 135,716.803 ft.³

The volume of the cylindrical tower, V₂ ≈ 135,716.803 ft.³

The volume of the (entire) silo, Vₙ = V₁ + V₂

∴ Vₙ = 11,309.7336 ft.³ + 135,716.803 ft.³ = 147,026.573 ft.³

The volume of the (entire) silo, Vₙ ≈ 147,026.6 ft.³.

Answer:

147,026.5 ft.³

Answer:

number of be television be 27 and  the number of movies would be 50

Step-by-step explanation:

The computation of the number of DVD sold and the number of television sold is shown below:

Let us assume the number of television be x

So, the number of movies would be (3x - 4)

Now according to the question the following equation is made

12(3x - 4) + 9x = $1167

36x - 48 + 9x = $1,167

45x = $1,215

x = 27

So, the number of be television be 27

And, the number of movies would be

= (3x - 4)

= 3(27) - 4

= 50

Heather puts together 2/5 of a puzzle on Saturday and 3/10 on Sunday. Nicole has the same puzzle, and she puts together 4/5 of her puzzle.How much more of the puzzle does Nicole put together than Heather? A. 1/10 b. 3/10 c. 1/5 d 4/5

total puzzle heather put together =

[tex]\frac{2}{5} + \frac{3}{10}[/tex]

[tex]\frac{4 + 3}{10}[/tex] = 7/10

the next step is to subtract 7/10 from the fraction Nicole put together

[tex]\frac{4}{5} - \frac{7}{10}[/tex]

[tex]\frac{8-7}{10}[/tex] = 1/10
