Answer:
Step-by-step explanation:
760·0.5^(t/9) = 19
0.5^(t/9) = 19/760
2^(-t/9) = 0.025
-t/9 = log₂(0.025)
t = -9log₂(0.025) = 47.9 minutes

factorise 6n-10
how do you do it?
Answer:
Step-by-step explanation:
given
6n - 10
Take 2 as common then
2 ( 3n - 5 )
hope it helps :)
Answer:
2(3n-5)
Step-by-step explanation:
You need to find the highest common factor (2 in this case).
When the word factorise is mentioned that means there has to be brackets in your answer.
After the highest common factor is found then divide the numbers by it. for example, 6÷2 and -10÷2.

A box has 70 cookies . 10% are broken (a) What fraction is broken ?
(b) What fraction remained whole?
Answer:
Step-by-step explanation:
70(10/100)=7 broken cookies.
7/70=1/10 is the fraction broken
(70-7)/70=63/70 is the fraction remaining whole
Answer:
(a) 1/7 are broken
(b) 6/7 remain whole
Step-by-step explanation:
70 is a nice number to deal with in terms of percentages and fractions. If 10% of the cookies are broken, do 10/70. That fraction simplified gets you 1/7. To find the remaining whole cookies. Do 7/7 - 1/7 = 6/7 (or if you already know that in your head that works too)
Three uniform shirts sell for $34.50. How much will 5 uniform shirts cost?
Answer:
57.5
Step-by-step explanation:
Recognize our numbers
3,5,34.50
Three uniform shirts sell for 34.50
34.50/3
=11.5
How much will five cost?
5x11.5
=57.5
Hope this helps!
Answer:
55.25
Step-by-step explanation:
1. First we need to work out the price of ONE shirt. To do that we divide the total price of 3 shirts by 3.
34.50 / 3 = 11.05
2. Now we know that the price of one shirt is $11.05p we can multiply that by 5 to get the price of 5 shirts.
11.05 * 5 = 55.25
= $55.25p
Which polynomial represents the sum below (8x^2 + 5x + 3) + (-5x^6 - 2x^5 - 4x^2 - 2x)
Answer:
-5x^6 - 2x^5 + 4x^2 + 3x + 3
Step-by-step explanation:
Combine like terms from each of the polynomials.
(8x^2 + 5x + 3) + (-5x^6 - 2x^5 - 4x^2 - 2x)
(8x^2 - 4x^2) + (5x - 2x) + (3) + (-5x^6) + (-2x^5)
(4x^2) + (3x) + (3) + (-5x^6) + (-2x^5)
Then, order them by degree.
-5x^6 -2x^5 + 4x^2 + 3x + 3
find the length of the missing side
Answer:
Choice D
Step-by-step explanation:
2ײ+5y-18 if x is 5 and y is 2
the answer is 659 because if x = 5 that means 25x25 = 625
and if y = 2 then 625 + 52 = 677
and then 677-18 = 659

One axis is used for kilograms, the other for pounds. When the x-axis is kilograms, the line includes points (1, 2.2), (2, 4.4), and (3, 6.6). The graph is a straight line that passes through the origin. The line is straight because unit conversions are proportional.
Which sets of side lengths could form a triangle?
A. 3 centimeters, 4 centimeters, 9 centimeters
B. 3 centimeters, 6 centimeters, 9 centimeters
C. 4 centimeters, 5 centimeters, 9 centimeters
D. 4 centimeters, 6 centimeters, 9 centimeters
Answer:
D. 4 centimeters, 6 centimeters, 9 centimeters
Step-by-step explanation:
Considering side length for forming a triangle, most of the time it is about Triangle Inequality Theorem, which for 3 sides length a,b,c, it must satisfy the following set of inequalities:
[tex]a+b>c\\a+c>b\\b+c>a[/tex]
By checking each of them only D satisfy:
[tex]4+6=10>9\\6+9=15>4\\9+4=13>6[/tex]
For simplicity you only have to check if the two shortest sides add up to be larger than the longest side:
[tex]4+6>9[/tex]

The seat of a bench is in the shape of a trapezoid with bases of 6 feet and 3 feet and a
height of 1.5 feet. What is the area of the seat?
The area of the seat is
ft.
Answer:
6.75 ft^2
Step-by-step explanation:
The area of the seat can be calculated as follows
a + b/2 × h
6+3/2 × 1.5
9/2 × 1.5
4.5× 1.5
= 6.75 ft^2
Hence the area of the seat is 6.75ft^2

(3.5 x 10^5) : (7x10^8)
What is the answer to this question?
: is divide
Answer:
5 • 10^-4 I evaluate this by using scientific notation.
The value of the ratio (3.5 x 10⁵) : (7x10⁸) is 0.0005.
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.
For example, 2x+3
To solve (3.5 x 10⁵) : (7x10⁸), we can simplify the expression by dividing the numerical coefficients and dividing the exponents separately.
Dividing the numerical coefficients 3.5 and 7, we get:
3.5 ÷ 7 = 0.5
Dividing the exponents 5 and 8, we get:
10⁵ ÷ 10⁸ = 10⁵⁻⁸
= 10⁻³
Therefore, the simplified expression is:
0.5 x 10⁻³
We can further simplify this expression by converting 10⁻³ to a decimal:
10⁻³ = 1/1000 = 0.001
So, the final answer is:
(3.5 x 10⁵) : (7x10⁸) = 0.5 x 10⁻³
= 0.5 x 0.001
= 0.0005
