Answer:

12.8

Step-by-step explanation:

Tan 52° = x/10

x = Tan 52° * 10

x = 1.2799 × 10

x = 12.799

Rounding to the nearest tenth, we have

x = 12.8

Answer:

Step-by-step explanation:

Let's use 52 as our degree.

The adjacent side to 52 is x, and the opposite is 10.

Since it's gonna be opposite over adjacent, we need to use the Tangent ratio.

(tan)

Now let's start our calculations.

Tan52 = x/10

(Tan52)(10) = x

x = 12.79941532

Let's round that to the nearest tenth place.

x = 12.8 units

(Don't forget the degree sign for 52 in Tan52!!!)

Hope that helped! :)

Answer:

3x + 6 =27

Step-by-step explanation:

A. The solution is 7! First I Subtracted 6 from both sides of the equation, Then I Divided both sides of the equation by the same term. Then I got "7" from doing the following.

B. The solution is the x in the answer which is the amount of juice he poured.

Option (4)

Step-by-step explanation:

If ΔLMN is similar to ΔQRS,

Their corresponding sides will be proportional.

[tex]\frac{LM}{QR}= \frac{MN}{RS}= \frac{LN}{QS}[/tex]

[tex]\frac{5}{6}= \frac{3}{4}= \frac{6}{7}[/tex]

But it's not true.

Therefore, the given triangles ΔLMN and ΔQRS are not similar.

Option (4) will be the answer.

Answer:

15.3 oz

Step-by-step explanation:

Here, we want to get the value of the new size after reduction

We start with reduction amount

That will be;

15/100 * 18 = 2.7 oz

So we now get what it can hold

That’s;

18-2.7 = 15.3 oz

Answer:

Step-by-step explanation:

2x^2+14x=520

x^2+7x-260

x(x+7)=260

so x=13

13x20=260

second

x^2+10x=875

x(x+10)=875

x= 25

25x35=875

Answer/Step-by-step explanation:

Since 320 is 10 times 32. The answer for 320 divided by 4 is going to be 10 times the answer of 32 divided by 4.

320 ÷ 4 = 80

32 ÷ 4 = 8

As 320 is 10 times of 32 then values results also 10 times.

One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.

Given:

We have to divide 32 by 4.

The division is as follow:

= 32/4

= (4 x 8)/ 4

= 8

If we multiply 10 to 32 then we get 320.

Then, if we multiply 10 to 8 we get

= 10 x 8

= 80

Answer:

About 5, 805 grams remaining.

Step-by-step explanation:

We are given that every 27 years, the mass of Element X decreases by half.

We can write an exponential function to model the situation. The standard exponential function is given by:

[tex]\displaystyle f(t)=a(r)^t[/tex]

Where a is the initial amount, r is the rate, and t is the time, in this case years.

Since it is halved, our rate r is 1/2.

Since it is halved for every 27 years, for t, it will be t/27.

Therefore, our function is:

[tex]\displaystyle f(t)=a\Big(\frac{1}{2}\Big)^{t/27}[/tex]

Our initial sample is 7,900 grams. Hence, a = 7900:

[tex]\displaystyle f(t)=7900\Big(\frac{1}{2}\Big)^{t/27}[/tex]

We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:

[tex]\displaystyle f(12)=7900\Big(\frac{1}{2}\Big)^{12/27}\approx5805\text{ grams}[/tex]

After 12 years, there will be about 5805 grams remaining.

Answer:

About 5, 805 grams remaining.

Step-by-step explanation:

We are given that every 27 years, the mass of Element X decreases by half.

We can write an exponential function to model the situation. The standard exponential function is given by:

→ f(t)=a(r)^t

Where a is the initial amount, r is the rate, and t is the time, in this case years.

Since it is halved, our rate r is 1/2.

Since it is halved for every 27 years, for t, it will be t/27.

Therefore, our function is:

→ f(t)=a(1/2)^t/27

Our initial sample is 7,900 grams. Hence, a = 7900:

→ f(t)=7900(1/2)^t/27

We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:

→ f(12)=7900(1/2)^12/27 ≈5805 grams

After 12 years, there will be about 5805 grams remaining.
