Answers:
1.6962 = 1.70 to 2 d.p. 0.007395 = 0.007 to 3 d.p. 0.4247 = 0.425 to 3 d.p. 0.007395 = 0.0074 to 4 d.p.-----------------------------
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.

Answers:
32549 = 32500 to 3 s.f. 909520 = [tex]91\overline{0}000[/tex] to 3 s.f. (note the overline bar) 32549 = 32550 to 4 s.f. 909520 = 909500 to 4 s.f.-----------------------------
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.
Which graph best describes a system of equations that has no solution
find the product of the following monomial
x^n * x^2
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)

People attending a football game either supported the home team or the visiting team. If 714 of the people attending supported the home team and 2686 supported the visiting team, what percentage supported the home team?
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}}=

Find the determinant of the following matrix. [1 -2] [3 4]
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

A rectangle has length 4 inches and width 2 inches. If the length and width of the rectangle are each reduced by 50 percent, by what percent will the area of the rectangle be reduced?
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 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

The function f is defined by f(x) = k/x+3, where k is a constant. Find k, if the graph of f passes through the point (3/4,0).
k=
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]
Use the remainder theorem to determine if x = 4 is a zero of the following polynomial and find the quotient and the remainder
p(x) = x2 + 11x - 60
ОА.
Yes, x = 4 is a zero of the polynomial
The quotient is x + 15, and the remainder is 0.
ОВ.
No, x = 4 is not a zero of the polynomial
The quotient is x + 15, and the remainder is 0
OC Yes x = 4 is a zero of the polynomial.
The quotient is x + 7, and the remainder is 0
D
No, x = 4 is not a zero of the polynomial.
The quotient is x + 7, and the remainder is -88
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.

Betty is making a quilt made of various patterns . She buys 3 sheets of fabric that each have an area of 30 square feet. She cuts them up into sections that are each 2/5 of a square foot . How many sections will she have total
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
