Answers

Answer:

1. T = -5 2. X = 12 3. X = 60

Step-by-step explanation:

5t + 17 = 4(t + 3)

1. Distribute 4

5t + 17 = 4t + 12

2. Isolate the variable

t + 17 = 12

t = -5

1/2x + 1/3x = 10

1. Remove fractions by multiplying the equation by 6

3x + 2x = 60

2. Combine like terms

5x = 60

3. Divide by coefficient

x = 12

1/4x + 2/5x = 39

1. Remove fractions by multiplying by 20

5x + 8x = 780

2. Combine like terms

13x = 780

3. Divide by coefficient

x = 60

The rule of the number pattern
Subtract 6 to get the next number
What will be the fifth number in the
sequence

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The rule gives the sequence ...

75, 69, 63, 57, 51, 45, ...

The 5th number in the sequence is 51.

Alternate solution

The equation for the general term of an arithmetic sequence is ...

an = a1 +d(n -1) . . . . . for first term a1 and common difference d

Your sequence has first term 75 and common difference -6, so the equation is ...

an = 75 -6(n -1)

Then for n=5, the term is ...

a5 = 75 -6(5 -4) = 75 -24 = 51

The 5th term is 51.

you are given that 4a - 2b =10 and a + c = 3. write an expression in a, b and c that is equal to 23. give your answer in its simplest form.

Answers

4a - 2b = 10
a + c = 3 so a = 3 - c and c = 3 - a

4(3 - c) - 2b = 10
12 - 4c - 2b = 10
-4c -2b = -2
2c - b = 1

Does anyone know the answer? If so how did you get the answer.

Answers

So if I remember correctly, so it tells you that the area is 96 ft and we have to find X. We already have two of the measurements and if 96 ft is the area (total) then we have to figure out the missing measurement that will add up with the other two to equal 96 ft. So what I did was that I added up 20 ft and 16 ft= 36 ft. So then you just minus 36 ft from 96 ft to get your answer (X) so X= 60 ft

so uh it’s x=60. Why? the person above said so

In ΔGHI, h = 10 cm, ∠G=152° and ∠H=7°. Find the area of ΔGHI, to the nearest square centimeter.

Answers

Answer:

Step-by-step explanation:

I = 180-152-7 = 21°

Law of Sines:

g = h·sinG/sinH ≅ 38.5 cm

i = h·sinI/sinH = 29.4 cm

Use Heron's Formula to calculate the area from the lengths of the sides.

semi-perimeter s = (g+h+i)/2 ≅ 39.0 cm

area = [tex]\sqrt{s(s-g)(s-h)(s-i)}[/tex]≅ 69 cm²

A team of biologists captured and tagged 65 deer in a forest. Two weeks later, the
biologists captured a sample of 30 deer from the same forest and found that 5 of
them were tagged. Which proportion could be used to estimate the number of deer in
the forest?

Answers

Answer:

1/6x= 65

Step-by-step explanation:

so we can assume that 5/10= 1/6 of the deer were tagged

lets call the total number of dear x

so 1/6x= 65

x= 380

The proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

To estimate the number of deer in the forest, we can set up a proportion using the tagged deer in the sample as a representative of the entire population.

Let's denote the number of deer in the forest as 'x'.

We know that 65 deer were tagged out of the total population. In the sample of 30 deer, 5 were tagged.

Therefore, we can set up the following proportion:

Tagged deer in sample / Total deer in sample = Tagged deer in population / Total deer in population

5 / 30 = 65 / x

Now we can cross-multiply to solve for x:

5x = 65 * 30

5x = 1950

Dividing both sides by 5:

x = 1950 / 5

x = 390

Therefore, the proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

A store manager buys binoculars for $45 each. He marks up the cost by 40% to get the store price. Then the store has a sale and the store price is reduced by 10%. What is the sale price of the binoculars?

Answers

Answer:

$56.70

Step-by-step explanation:

The cost plus markup is found by multiplying $45 by 1.40: $63.

With the 10% price reduction, the sale price is 0.90($63) = $56.70.

Regarding 1.40: the '1' results in the full price to the manager plus the '0.40' markup.
