shown below, what does it mean?

Step-by-step explanation:

4x=3×8

4x=24

x=24÷4

x=6

Answer:

False

The answer is 343 not 345

Step-by-step explanation:

7^5 / 7^2 =

16807 / 49 =343

Answer:

False.

7⁵ ÷ 7²

= 7⁽⁵⁻²⁾

= 7³

= 343

As x → 10 from above, h(x) is steadily approaching 18.5.

According to the table, the limit of h (x) as x approaches 10 plus is 18.5

From the table, the value of the function at x = 10 is:

h(10) = undefined

As x exceeds x = 10, the function values become:

h(x+) = 18.5......

When approximated, we have:

h(x+) = 18.5

Hence, the limit of h (x) as x approaches 10 plus is 18.5

Answer:

D. ∆ABC ~ ∆DEF

Step-by-step explanation:

The triangles given shows that the three corresponding angles of both triangles are congruent to each other. This means that they have the same shape but different size.

Triangles that are congruent to each other have the same shape and the same size while triangles that have the same shape but different size are similar to each other.

Therefore, ∆ABC is similar to ∆DEF (∆ABC ~ ∆DEF).

Answer:

Let L be the number of losses. T is the total number of games, and it has the value 64. W is the number of wins.

They won 28 more than they lost, so W = L + 28.

Since W = L + 28, W = 18 + 28 = 46.

Tell me if this makes sense..! if it dont ill explain it more clearly! :)

Answer:

The porter charges Rs 300 at this rate.

Step-by-step explanation:

We solve this question by proportions, using rule of three.

75 Rs - 4 km - 50 kg

x Rs - 10 km - 80 kg

Relationship between the variables:

As the distance, or the weight increase, the rate will increase. This means that:

[tex]\frac{75}{x} = \frac{4*50}{10*80}[/tex]

[tex]\frac{75}{x} = \frac{200}{800}[/tex]

[tex]\frac{75}{x} = \frac{2}{8}[/tex]

[tex]x = \frac{75*8}{2} = 75*4 = 300[/tex]

The porter charges Rs 300 at this rate.

27.76% I believe. infinite decimal.

Answer: 27.75 decrease

Step-by-step explanation:

45 times .85 (100-15(perecent)= 85) is a
a times .85 is b
(b-45)/45 is -0.2775 which is 27.75% which is -27.75

Answer:

0

Step-by-step explanation:

f(x) = y

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

f(2) = 0

Answer:

x = 5+6y

Step-by-step explanation:

Let x represents the age of the father and  y represents the present age of the son.

ATQ,

The present age of  the father is 5 more than 6 times the  age of the son. We can write it in the form of equation as follows :

6 times the  age of the son means 6y. So,

x = 5+6y

Hence, the mathematical equation is "x = 5+6y".

Answer:

100 Minutes.

Step-by-step explain:

25 divided by 3 = 8.33333333333, So, 8.3 minutes to paint one section at a time. So, 8.3 x 12 = 99.6. So, 99.6 rounded since the last number is higher than 5 it would go to the next number. So, rounded its 100 minutes.  100 minutes for Angela to paint 12 sections.

Answer:

I would say it is B

Step-by-step explanation:

Because to find the value of x, you would need to divided 232.30 by 10.10, you have to use the opposite for algebra so the opposite is multiplication.

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.
