QUESTION:estimate the equation 12+19.61.Answer:12+19.61 =31.61.

Answer:

62/9

Step-by-step explanation:

.88888888 is 8/9

Multiply 9*6 to get the whole amount

9*6 = 54

Add 8 because that's the fractional amount.

54 + 8 = 62

So 62/9 will give you 6.8888888889

Answer:

3

Step-by-step explanation:

Because Johns friends both got 3 and 5 so he needs a number higher to win i.e 6, 7, 8 so the answer is three.

Second  Option is correct.  

There will be  3 desired outcomes John should use in his probability calculation.

Probability is the measure of the likelihood of occurrence of an event.

An outcome is a possible result of an experimental or trial.

[tex]P(A) = \frac{number of favorable outcomes }{Total number of outcomes}[/tex]

where,

P(A) is the probability of an event.

According to the given question

we have

sample space = {1,2,3,4,5,6,7,8}

Total number of outcomes = 8

Jhon needs to spin a number higher than both friends in order to win the game

⇒ the numbers must be greater than 5

⇒ the numbers will be 6, 7, 8

therefore,

the total number of favorable outcomes =3.

Hence. there are 3 desired outcomes should John use in his probability calculation.

Answer:

$11

Step-by-step explanation:

92=$9.20

100?

920/100x110/92

After this you will get 11 dollars.

That is the amount to send 110 text messages.

The cost to send 110 text messages is $11.

Given that, it cost Paisley $9.20 to send 92 text messages.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the cost to send 110 text messages be x.

Now, 9.20:92::x:110

⇒ 9.20×110=92×x

⇒ 92x=1012

⇒ x=1012/92

⇒ x=$11

Hence, the cost to send 110 text messages is $11.

Answer:

See below.

Step-by-step explanation:

Refer to the graph.

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values is all values greater than or equal to 0.

Therefore, our range is, in interval notation:

[tex][0,\infty)[/tex]

Note that we use brackets with the 0 because 0 is included in our range.

In set notation, this is:

[tex]\{y|y\in\mathbb{R},y\geq 0\}[/tex]

Answer: B

(height of a building in feet, height of the building in inches)

Answer: OPTION 3. -7

Step-by-step explanation:

Given

-52=-4x-5(-2x+2)

Distributive property (REMEMBER you need to change signs)

-52=-4x-5×(-2x)-5×2

-52=-4x+10x-10

Combine like terms (-4x and 10x)

-52=6x-10

Add 10 on both sides

-52+10=6x-10+10

-42=6x

Divide 6 on both sides

-42/6=6/6x

x=-7

Please let me know if you have any question

Answer:

[tex]g[/tex] = 22.5°

[tex]f[/tex] = 67.5°

Step-by-step explanation:

Let’s create a system of equations for [tex]f[/tex] and [tex]g[/tex].

Complementary angles are two angles that add up to 90°, so [tex]f+g=90[/tex]

Also, [tex]f[/tex] is thrice of g: [tex]f=3g[/tex]

We can now substitute [tex]3g[/tex] in [tex]f+g=90[/tex] for [tex]f[/tex].

[tex]3g + g = 90\\\\4g = 90\\\\g=22.5[/tex]

Now, we can find [tex]f[/tex] by substituting [tex]g[/tex] into either equation.

[tex]f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5[/tex]

Answer:

[See Below]

Step-by-step explanation:

✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:

  ✧ Square ∼ s² (Side Squared)

  ✧ Triangle ∼ ½ × b × h

✦ So now just solve for each area:

  ✧ Square ∼ 15² = 225

  ✧ Triangle ∼  ½ × 15 × 3 = 22.5

✦ Now add each area together to get the total area:

  ✧ 225 + 22.5 = 247.5

Answer:

$36,529.26

Step-by-step explanation:

To find the answer, you need to use the formula to calculate the present value:

PV=FV/(1+i)^n, where:

PV= present value

FV= future value= $200,000

i= interest rate= 12%

n= number of periods of time= 15

Now, you have to replace the values in the formula:

PV=200,000/(1+0.12)^15

PV=200,000/(1.12)^15

PV=36,539.26

According to this, the answer is that you need $36,529.26 today.

Answer:c

Step-by-step explanation:

This is how it should be when you are representing an exponential equation to a logarithmic equation

[tex]y=a^{x}[/tex]→log y base a =x

therefore the answer is c

The exponential equation which rewrites the logarithmic equation is given by 6ˣ = 18

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

log₆ 18 = x

From the properties of logarithm , we get

log Aⁿ = n log A

On simplifying , we get

6ˣ = 18

where the value of x = 1.61314

Hence , the exponential equation is 6ˣ = 18

Answer:

5

Step-by-step explanation:

-6b> -8-22

-6b> -30

b> -30/-6

b>5

Answer:

So we have this inequality:

[tex]-6b + 22 > -8[/tex]

We substract 22 on both sides:

[tex]-6b > -30[/tex]

Now, we divide both sides by -6 and we change the sign, as, when we multiplicate or divide by a negative number we always have to do it:

[tex]b < \frac{-30}{-6}[/tex]

[tex]b < 5[/tex]

So we know b < 5, so the biggest integer b can represent is 4. Note that the solution is any number which is smaller than 5.
