Answer:

4. 72 m

5. 42 m

6. 66 yd

8. 18 yd

9. 200 cm

Step-by-step explanation:

3) 1 × 3 × 8 + [5 × 8 × (4-3)] = 24 + 40 = 64 yd³

4) 9 × 1 × 8 = 72 m³

5) 3 × 7 × 2 = 42 m³

6) 3 × 3 × (6 - 2) + 2 × 5 × 3 = 36 + 30 = 66 yd³

7) (7 - 5) × 7 × 3 + 8 × 7 × 5 = 42 + 280 = 322 mm³

8) 3 × 3 × 2 = 18 yd³

9) 8 × 5 × 5 = 200 cm³

Answer:

Step-by-step explanation:

Simplifying

5(2x + -6) + 20 = 10

Reorder the terms:

5(-6 + 2x) + 20 = 10

(-6 * 5 + 2x * 5) + 20 = 10

(-30 + 10x) + 20 = 10

Reorder the terms:

-30 + 20 + 10x = 10

Combine like terms: -30 + 20 = -10

-10 + 10x = 10

Solving

-10 + 10x = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 10x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 10x = 10 + 10

10x = 10 + 10

Combine like terms: 10 + 10 = 20

10x = 20

Divide each side by '10'.

x = 2

Simplifying

x = 2

Answer:

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(2x−6)+20=10

Step 1: Simplify both sides of the equation.

5(2x−6)+20=10

(5)(2x)+(5)(−6)+20=10(Distribute)

10x+−30+20=10

(10x)+(−30+20)=10(Combine Like Terms)

10x+−10=10

10x−10=10

Step 2: Add 10 to both sides.

10x−10+10=10+10

10x=20

Step 3: Divide both sides by 10.

10x

10

Answer:

El verano sucede a las 23.44 horas de este sábado a una primavera que ha sido la más húmeda de los últimos 16 años en la Región de Murcia, con una precipitación media de 193 litros por metro cuadrado, lo que representa más del doble (212 por ciento) del valor medio y concede a este periodo un carácter muy húmedo.

Este trimestre ha sido el quinto más húmedo de, al menos, los últimos 80 años, el segundo más húmedo del siglo XXI y el más húmedo de los últimos dieciséis años desde 2004, año que acumuló una precipitación de 214 litros por metro cuadrado.

En cuanto a las temperaturas, este trimestre, que comprende de marzo a mayo de 2020, tuvo un carácter termométrico muy cálido, con una temperatura media de 15,9 grados centígrados y una anomalía de +0,8.

“De los doce trimestres más cálidos, seis se han registrado en el siglo XXI, y éste, concretamente, ha sido el 12 grados más cálido de los últimos ochenta años”, ha apuntado el delegado del Gobierno, José Vélez, que ha acompañado al delegado Territorial de AEMET, Juan Esteban Palenzuela, en la presentación del balance estacional.

Answer:

NO

Step-by-step explanation:

Let h(t) represent the distance the pack is located above the ground at time t.  Then h(t) = 20 ft - 16t^2 ft.  Notice how h = 20 ft (the initial height) and that it decreases as t increases.

How long does it take for the pack tohit the ground?  Set h(t) = 0 and solve for t:

0 ft = 20 ft - 16t^2 ft yields 16t^2 ft = 20, or t^2 ft = 20/16, which is greater than 1.  So the question "Will the backpack hit the ground in 1 second" is answered by NO.

Answer:

[tex]y = 18 \\ x = 7.8[/tex]

We can create a ratio of length to width. The length of the model is 8, while the width is 6. This is a 4:3 ratio of length to width. We can input this into the actual length, 4(5):3(5) = 20:15. Therefore, the actual width is 15 yd

Answer:

Here we go. System of equations:

Step-by-step explanation:

y = 18x + 75

y = 22x + 40

2 equations with 2 unknown,,, x= 35/4, and you will find y= 232.5......then you will have system of linear equation will graph.

Answer:

y < 5x + 5

Step-by-step explanation:

find slope and y-intercept first:

for slope I used the formula with these two points:  (0,5) and (-1,0) and the y-intercept can be seen at (0,5)

so equation is y = 5x + 5

but we need to select an inequality symbol, because line is dashed it must be either > or <

I used the point (0, 0) to determine the sign:

is this true or false? 0 > 5(0) + 5   False

so the sign must be <

Check:  is this true or false? 0 < 5(0) + 5   True

Step-by-step explanation:

Answer:

(a) [tex]Pr = 0.3024[/tex]

(b) [tex]Pr = 0.6976[/tex]

(c) [tex]Pr = \frac{^9P_{n-1}}{10^{n-1}}[/tex]

Step-by-step explanation:

Given

[tex]Start = \{5,6,7,8\}[/tex] i.e. between 4 and 9

[tex]n(Start) =4[/tex]

[tex]Digits = 5[/tex]

Solving (a): Probability that each of the 5 digit are different

Since there is no restriction;

The total possible selection is as follows:

[tex]First\ digit = 4[/tex] (i.e. any of the 4 start digits)

[tex]Second\ digit = 10\\[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Third\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Fourth\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Fifth\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

So, the total is:

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

[tex]Total = 40000[/tex]

For selection that all digits are different, the selection is:

[tex]First\ digit = 4[/tex] (i.e. any of the 4 start digits)

[tex]Second\ digit = 9[/tex] (i.e. any of the remaining 9)

[tex]Third\ digit = 8[/tex] (i.e. any of the remaining 8)

[tex]Fourth\ digit = 7[/tex] (i.e. any of the remaining 7)

[tex]Fifth\ digit = 6[/tex] (i.e. any of the remaining 6)

So:

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex]

[tex]Selection =12096[/tex]

So, the probability is:

[tex]Pr = \frac{Selection}{Total}[/tex]

[tex]Pr = \frac{12096}{40000}[/tex]

[tex]Pr = 0.3024[/tex]

Solving (b): At least 1 repeated digit

The probability calculated in (a) is the all digits are different i.e. P(None)

So, using laws of complement

We have:

[tex]P(At\ least\ 1) = 1 - P(None)[/tex]

So, we have:

[tex]Pr= 1 - 0.3024[/tex]

[tex]Pr = 0.6976[/tex]

Solving (c): An expression to model the probability.

Using (a) as a point of reference, we have;

[tex]Pr = \frac{Selection}{Total}[/tex]

Where

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex] ---- for selection of 5 i.e. n = 5

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex]

This can be rewritten as:

[tex]Selection = 4 * ^9P_4[/tex]

4 can be expressed as: 5 - 1

So, we have:

[tex]Selection = (5-1) *^9P_{5-1}[/tex]

Substitute n for 5

[tex]Selection = (n-1) *^9P_{n-1}[/tex]

[tex]Selection = (n-1)^9P_{n-1}[/tex]

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

This can be rewritten as:

[tex]Total = 4 * 10^4[/tex]

[tex]Total = (5-1) * 10^{5-1}[/tex]

[tex]Total = (n-1) * 10^{n-1}[/tex]

[tex]Total = (n-1) 10^{n-1}[/tex]

So, the expression is:

[tex]Pr = \frac{(n-1)^9P_{n-1}}{(n-1)10^{n-1}}[/tex]

[tex]Pr = \frac{^9P_{n-1}}{10^{n-1}}[/tex]

Where n represents the digit number

Answer:

2 7/12

Step-by-step explanation:

1st do 3-1=4

1112−412=?

The two fractions have like denominators so you can subtract the numerators.

Then:

11−412=712

This fraction cannot be reduced.

Therefore:

1112−412=712

Solution by Formulas

Apply the fractions formula for subtraction, to

1112−412

and solve

(11×12)−(4×12)12×12

=132−48144

=84144

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(84,144) = 12

84÷12144÷12=712

Therefore:

1112−412=712

Answer:

The area of this composite figure is 122.75 m².

Step-by-step explanation:

What I can go on ahead & do is split this figure into a 5 * 16 rectangle and a 9 by 9.5 triangle.

(5 * 16) + 1/2(9 * 9.5) {Multiply 5 by 16 first; go from left to right}

80 + 1/2(9 * 9.5) {Now multiply 9 by 9.5}

80 + 1/2(85.5) {Then multiply 85.5 by 1/2, which is the same thing as dividing by 2}

80 + 42.75 {Lastly, add the two values together}

122.75 m²

The area of this composite figure is 122.75 m².
