Answer:

15 boys

Step-by-step explanation:

7+3=10

10x5=50

there are 3 boys so

3x5=15

Answer:

35

Step-by-step explanation:

Assume 3x is the number of boys in the class.

And 7x as for the girls.

3x+7x=50

10x=50

x=5

Thus, 7*5=35 boys in the science class

Answer:

2x + y = 20 .     y=3x

2x + 3x = 20

5x = 20

x/5 = 20/5

x = 4

Edad de Eva = x

Edad de Ana = x - 12

Dentro de los 7 años de la edad de Eva, la edad de Ana será el doble

x + 7 = 2 (x - 12 + 7)

x + 7 = 2 (x - 5)

x + 7 = 2x - 10

x - 2x = - 10 - 7

-x = - 17

x = 17

Por lo tanto, Eva tiene 17 años.

Answer:

The length of side of original square is: 20 inches

Step-by-step explanation:

Let x be the length of side of original square

Then x+5 will be the side of new square

Th formula for perimeter is:

[tex]P = 4*side[/tex]

As we know the perimeter of the new square we can use the perimeter to find the value of x

[tex]100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20[/tex]

The value of x is 20 inches.

Hence,

The length of side of original square is: 20 inches

Answer:

5 ft/yr

Step-by-step explanation:

This is the whole question: A tree initially measured 18 ft tall. Over the next 3 1/2 years, it grew to a final height of 35 1/2 feet. During those 3 1 /2 years, what was the average yearly growth rate of the height of the tree?

The tree grew   35.5 - 18 ft = 17.5 feet in 3.5 years      

This average leads to   17.5 ft / 3.5 yr =  5 ft/yr

The question is incomplete, the complete question is;

A tree measured 18 feet tall. Over the next 3 1/2 years, it grew to final height of 35 1/2 feet. During those 3 1/2 years, what was the average yearly  growth rate of the height of the tree?

Answer:

5 feet per year

Step-by-step explanation:

Given that the initial height of the tree = 18 feet

Final height of the tree = 35.5 feet

Time interval = 3.5 years

Now;

Increase in length of tree = Final height of the tree - initial height of the tree

Increase in length of tree =  35.5 - 18 = 17.5 feet

Rate of growth of tree = increase in height of tree/ time taken

Rate of growth of tree = 17.5 feet/ 3.5 years

Rate of growth of tree = 5 feet per year

Answer:

9 is the answer

Step-by-step explanation:

1. 31 = 9/3+6 <------- This is the original equation.

2. 31 = 3+6    <------- Simplify the fraction.

3. 31 = 9        <-------- This is the final answer.

Hope this helps! I did the best I could. :)

Answer:

x = 12

Step-by-step explanation:

Lets set up the equation!

Complementary angles equal 90 degrees.

2x + 20 + 3x + 10 = 90

Now lets combine the like terms!

2x + 3x 20+ 10

5x +30 = 90

Now subtract 30 from both sides!

5x = 60

Divide each side by 5

x = 12

Answer:

[tex]T_{10} = 0.05078125[/tex]

[tex]S_{18} = 51.9998016358[/tex]

Step-by-step explanation:

Given:

Sequence = 26, 13, 6.5 ....

Solving (a): The 10th term

The sequence is a geometric progression and the nth term will be solved using:

[tex]T_n = ar^{n-1}[/tex]

In this case:

[tex]n = 10[/tex]

[tex]r = \frac{T_2}{T_1}[/tex] --- Common Ratio

[tex]r = \frac{13}{26}[/tex]

[tex]r = 0.5[/tex]

[tex]a = 26[/tex] --- First term

So, [tex]T_n = ar^{n-1}[/tex] becomes

[tex]T_{10} = 26 * 0.5^{10-1}[/tex]

[tex]T_{10} = 26 * 0.5^{9}[/tex]

[tex]T_{10} = 26 * 0.001953125[/tex]

[tex]T_{10} = 0.05078125[/tex]

Solving (b): The sum of first 18 terms

This will be calculated using:

[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]

Substitute values for n, a and r

[tex]S_{18} = \frac{26 * (1 - 0.5^{18})}{1 - 0.5}[/tex]

[tex]S_{18} = \frac{25.9999008179}{0.5}[/tex]

[tex]S_{18} = 51.9998016358[/tex]

Hence, the sum of first 18 terms is 51.9998016358

Answer:

[tex]x^{3}-8x^{2} +5x+14[/tex]

Step-by-step explanation:

n=3

f(x) = (x-(-1))(x-2)(x-7)

=(x+1)(x-2)= [tex](x^{2} -x-2)[/tex](x-7)=[tex]x^{3}-8x^{2}+5x+14[/tex]

Answer:

a. not sure

b. yes

Step-by-step explanation:

According to the given scenario, the following information is mentioned

[tex]\alpha[/tex] =0.025

In the case when the alpha is equivalent to 0.025 so the p test value would be more than the significance level i.e. 0.025 as the prescribed test is not important

So here

p>0.025

In the above case i.e. p>0.025 this does not mean that p>0.2 so we are not sure about this case whether he made teh same decision or not

Now in the another case, if the significant level is 0.005 so we are sure that p>0.005 as it is more than 0.025 so here also the test is not significant

So, here the same decision could be made

Answer:

-7/4

1/8

Step-by-step explanation:

1. If the problem is; (1 3/4) / (1/2 - 1 1/2)^(3)

(a). Convert to improper fractions;

(7/4) / (1/2 - 3/2)^3

(b). Simplify;

(7/4) / (-2/2)^3

(7/4) / (-1)^3

(7/4) / (-1)

-7/4

2. If the problem is; ((1 3/4) / (1/2)) - (1 1/2)^3

(a). Convert to improper fractions;

((7/4)/ (1/2)) - (3/2)^3

(b). Simplify;

((7/4)/ (1/2)) - (3/2)^3

((7/4)*(2/1)) - (27/8)

(7/2) - (27/8)

(28/8) - (27/8)

1/8
