- 7/11 = 0.636363

- 18/25 = -0.72

Section 1

Answers:

-----------------------------

Explanation:

The abbreviation d.p. means decimal places

When rounding to 2 decimal places, we look at the digit in the third decimal place value slot (thousandths place). If the value is 5 or larger, then we round up. In the case of 1.6962, the second 6 tells us to round 1.69 up to 1.70

Something like 0.4247 does not round up because that second 4 is not 5 or larger. So we just are left with 0.42

The same logic applies to three decimal places, but you'll look in the fourth slot this time.

Section 2

Answers:

-----------------------------

Explanation:

Recall that for a number like 32500, the 0s are not significant. This is because we can write that as 3.25 * 10^4 to convey the same idea. The only significant figures are 3, 2 and 5.

So when rounding 32549 to 3 sig figs, we just pick on the three left most values, and the rest go to 0. The 325 does not round up to 326 because the '4' isn't 5 or larger. Put another way: 32549 is closer to 32500 than it is to 32600

When rounding 909520 to three sig figs, it turns into [tex]91\overline{0}000[/tex]. The line over the first '0' tells us that zero is significant. Without this bar, the zero would be considered not to be significant. The 9095 is closer to 9100 than it is to 9000, so that's why we rounded up.

Answer:

The value of k  if the graph of f passes through the point (3/4,0) is [tex]\mathbf{k=-\frac{9}{4}}[/tex]

Step-by-step explanation:

We are given the function: [tex]f(x)=\frac{k}{x}+3[/tex] where k is constant.

We need to find k, if the graph of f passes through the point (3/4,0).

So, graph passes through point (3/4,0) we have x=3/4 and y =0

Putting value of x in given function we can find value of x

We have f(x)=0, and x= 3/4

[tex]f(x)=\frac{k}{x}+3\\0=\frac{k}{\frac{3}{4} }+3[/tex]

Using fraction rule: [tex]\frac{a}{\frac{b}{c} }=\frac{a.c}{b}[/tex]

[tex]0=\frac{4k}{3 }+3\\Taking \ LCM\\0=\frac{4k+9}{3}\\3*0=4k+9\\0=4k+9\\4k=-9\\k=\frac{-9}{4}[/tex]

So, The value of k  if the graph of f passes through the point (3/4,0) is [tex]\mathbf{k=-\frac{9}{4}}[/tex]

Answer:

21%

Step-by-step explanation:

First find the whole, the total number of attendees:

714 \text{ home} + 2686 \text{ visiting} = \color{orange}{3400} \text{ total attendees}

714 home+2686 visiting=3400 total attendees

Method 1: Set up a proportion

Set up an equation of the form:

\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=

whole

part

​  

=

\,\,\frac{\color{blue}{\text{percent}}}{100}

100

percent

​  

Assign the variable xx to the unknown value:

\color{blue}{x}=

x=

\,\,\color{blue}{\text{percent}}

percent

The question asks what \textit{percent}percent of all the attendees is 714

Substitute the known values with the numbers given in the problem, and the unknown value with xx:

\frac{\color{red}{714}}{\color{orange}{3400}}=

3400

714

​  

=

\,\,\frac{\color{blue}{x}}{100}

100

x

​  

Solve for xx:

100\cdot\color{red}{714}=

100⋅714=

\,\,\color{orange}{3400}\cdot\color{blue}{x}

3400⋅x

Cross multiply

\frac{71400}{3400}=

3400

71400

​  

=

\,\,\frac{3400x}{3400}

3400

3400x

​  

Divide both sides by 100

\color{blue}{21\%}=

21%=

\,\,\color{blue}{x}

x

Simplify

Method 2: Find percent directly

\text{Find \(714\) out of \(3400\) as a decimal:}

Find 714 out of 3400 as a decimal:

\frac{\color{red}{714}}{\color{orange}{3400}}=

3400

​  

=

0.21

\text{Convert decimal to percent:}

Convert decimal to percent:

0.21\times100=

0.21×100=

Answer:

67 to the power of 14

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

[1 -2]

[3 4]

We can obtain the determinant of the above matrix by doing the following:

Determinant =(1 × 4) – (3 × –2)

Determinant = 4 – – 6

Determinant = 4 + 6

Determinant = 10

Thus, the determinant of the above matrix is 10

Answer:

She will have 12 sections per fabric and 36 sections in all

Step-by-step explanation:

Betty buy 3 fabrics of 30 ft²

If she cut each to 2/5 of 1 ft²

Then she will have

30 × 2/5

= 6 × 2

= 12

She will have 12 for each fabric and for the 3 fabrics, she will have

12 × 3 = 36

Step-by-step explanation:

Answer:

225 sections

Step-by-step explanation:

Each fabric has an area of 30 sq ft.

All 3 fabrics have a total area of 3 * 30 sq ft = 90 sq ft.

Each sections has an area of 2/5 sq ft.

number of sections = total area of fabric / area of each section

90/(2/5) = 90 * 5/2 = 450/2 = 225

Answer: 225 sections

Given:

The polynomial is

[tex]p(x)=x^2+11x-60[/tex]

To find:

Whether x = 4 is a zero of the given polynomial by remainder theorem and find the quotient and remainder.

Solution:

According to the remainder theorem, if (x-c) divides a polynomial p(x), then the remainder is p(c).

Divide the polynomial by (x-4) and check whether the remainder p(x)=0 at x=4.

Putting x=4 in the given polynomial, we get

[tex]p(4)=(4)^2+11(4)-60[/tex]

[tex]p(4)=16+44-60[/tex]

[tex]p(4)=60-60[/tex]

[tex]p(4)=0[/tex]

Since, remainder is 0, therefore, (x-4) is a factor of p(x) and x=4 is a zero.

Now, on dividing p(x) be (x-4) we get

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{x^2+15x-4x-60}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{x(x+15)-4(x+15)}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{(x+15)(x-4)}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=x+15[/tex]

The quotient is x+15 and remainder is 0.

Therefore, the correct option is A.

Answer:

x^(n+2)

Step-by-step explanation:

When multiplying two monomials with the same base but different exponents,

under the multiplication rule of exponents,

the product becomes the base number to the power of the sum of the exponents.

For example:

[tex]a^2 + a^1 = a^(1+2)[/tex]

Therefore, since x^n and x^2 both have x as their bases,

the product becomes x^(n + 2)

Answer: 25%

Step-by-step explanation:

Given: A rectangle has length 4 inches and width 2 inches.

Area = Length x width

= 4 inches x  2 inches

= 8 square inches

If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]

If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]

Reduced area = (reduced length) x (reduced width)

= 2 inches x 1 inch

= 2 square inches

The percentage of the area of the rectangle be reduced :-

[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]

Hence, the percent of the area of the rectangle be reduced = 25%

In multiplication, the exponents add up.

5.5²=5¹.5²=5³

Note:

In the extraction ,the exponents remove.

5¹⁰÷5³=5⁷

Answer:

5³

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

Given

5 × 5²

= [tex]5^{1}[/tex] × 5²

= [tex]5^{(1+2)}[/tex]

= 5³ ← in index form

= [ 125 ]

Step-by-step explanation:

Step-by-step explanation:

If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

d=-7+3=-3-1=1-5=-4

so it is an arithmetic sequence
