Expand the following expression 5x(3 – 7y)

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:

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:

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.

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:

g≥-20

Step-by-step explanation:

The quotient of a number g and -4 is expressed as;

g/-4

If the quotient of a number g and -4 is at most 5, this is expressed as;

g/-4 ≤ 5

Multiply both sides by -4

g/-4 * -4 ≤ 5 * -4

g *  ≥ -20

Hence the required solution is g≥-20

Answer:

32

Step-by-step explanation:

Answer:

Right angle

Step-by-step explanation:

Given

Right angle and Acute angle

Required

Which is greater

An acute angle has its angles less than 90 degrees while a right angle has its angle to be exactly 90 degrees

Take for instance:

[tex]Acute\ Angle = 80[/tex]

[tex]Right\ Angle = 90[/tex]

By comparison: 90 > 80

So, right angle is greater.

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:

Step-by-step explanation:

There isn't an exact answer for the first one since there are no like terms. But the steps to get 13x + 2= 41.

You'd have to find x.

In order to find x, you'll need to subtract 2 on both sides

13x + 2 = 41

      - 2 = - 2

You'll end up with:

13x = 41

Next step is to divide 13 on both sides.

13x/ 13 = 41/ 13

So, x = 41/ 13

Or simplified to 3.153

Answer:

-5

Step-by-step explanation:

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:

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.
