Answer:

3/10

Step-by-step explanation:

total boxes = 100

shaded boxes = 30

fraction =30/100

= 3/10

Answer:

AX / AB = 6/18 = 1/3

AY / AC = 10/25 = 2/5

They are not similar because the two ratios is not the same.

Step-by-step explanation:

I'm not really sure okay!

Note that [tex]\frac{AX}{AB}=\frac{6}{24} =\frac{1}{4} ,and\frac{AY}{AC}=\frac{10}{35}=\frac{2}{7}.[/tex]

Because the ratio of the lengths of corresponding sides of the triangles are not equal, the triangles are not similar.

Answer:

[tex] \frac{25}{16} \: \: or \: \: 1\frac{9}{16} [/tex]

Step-by-step explanation:

[tex]( \frac{5}{4} )^{3} = \frac{ {5}^{3} }{ {4}^{3} } = \frac{5 \times 5 \times 5}{4 \times 4 \times 4} = \frac{5 \times 25}{20 \times 4} = \frac{25}{4 \times 4} = \frac{25}{16} = 1 \frac{9}{16} [/tex]

Rs.13680 is the answer.

Step-by-step explanation:-

Given-

• Principal (P) = Rs.57,000

• Rate (r%) = 6%

[tex]→ \frac{6}{100} [/tex]

[tex]→ 0.06[/tex]

• Time (n) = 4 years

Applying Interest formula,

[tex]→In=P \times R \times T[/tex]

[tex]→57,000 \times 0.06 \times 4[/tex]

[tex]→Rs.13680[/tex]

Hence, the interest is Rs.13680

Answer:

85%

Step-by-step explanation:

P(a) = 25%=1/4

P(b) = 60%=3/5

P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%

Answer:

The probability of A and B is 85%

Step-by-step explanation:

It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

Since you cannot have a decimal amount of a bag, you should purchase

(rounding)

7 bags of fertilizer

Answer:

7 bags

Step-by-step explanation:

First thing you need to do is figure out the area of the garden. Area=length×width, so just put in your numbers, 35×75=2625 square feet. One bag covers 400 feet, so you divide the area by 400, 2625÷400=6.5625. You can't buys 6.5625 bags of fertilizer, so you have to go up to the next whole number which is 7.

[tex](a-b)(a+c)[/tex]

Step-by-step explanation:

Factor each half of the expression separately:

[tex]a^2-ba+ac-cb\\a(a-b)+c(a-b)[/tex]

Since both a and c are being multiplied by a-b, we can combine them to get:

[tex](a-b)(a+c)[/tex]

Answer:

[tex]\frac{7}{3} =2\frac{1}{3}[/tex]

Step-by-step explanation:

For the problem:

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

The Least Common Multiple (LCM) of 3 and 6 is 6. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

[tex]\frac{5}{3} +\frac{4}{6} =\frac{5*2}{3*2} +\frac{4}{6} =\frac{10}{6} +\frac{4}{6}[/tex]

Now that the fractions have like denominators, add the numerators:

[tex]\frac{10}{6} +\frac{4}{6} =\frac{10+4}{6} =\frac{14}{6}[/tex]

The Greatest Common Factor (GCF) of 14 and 6 is 2. The result can be simplified by dividing both the numerator and denominator by 2.

[tex]\frac{14}{6} =\frac{14/2}{6/2} =\frac{7}{3}[/tex]

7 ÷ 3 = 2R1, therefore:

[tex]\frac{7}{3} =2\frac{1}{3}[/tex]

Answer:

19.7 inches

Step-by-step explanation:

circumference of a circle = 2πr

62 = 2*22/7 *r

r = 62 * 7 / 44 = 9.86

diameter = 2* r

= 2* 9.86

= 19.7 inches

Answer:

x=14.87

Step-by-step explanation:

What we want to use is pythagoras theorem:

a^2+b^2=c^2, where c is the hypotenuse

10^2+11^2=x^2

221=x^2

x=[tex]\sqrt{221}[/tex]

x=14.866...

x=14.87

480 minutes would be the answer

Step-by-step explanation:

Answer:

480 minutes

Step-by-step explanation:

We can write this relationship as [tex]y=0.11x+18[/tex] and then solve for x when y=70.80:

[tex]y=0.11x+18\\\\70.80=0.11x+18\\\\52.80=0.11x\\\\480=x[/tex]

Therefore, you spent 480 minutes talking.

Answer:

if 2x-1 is a factor of the polynomial f(x)= 8^3 +4^2+kx+15 where is a constant find the value of k and factorise f(x) completely when k has this value

Answer:

B

Step-by-step explanation:

f(x) = x³

g(x) = (x - 3)³ - 2

The inside of the parenthesis represents a horizontal shift

If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.

The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.

the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units

we can conclude that g is shifted 3 units right and 2 units down

the answer is B
