Answer:
15
Step-by-step explanation:
Let the smallest integer be x. The integers will be x, x+1, x+2, all the way up to x+6.
119 = 7x + (1+2+3+4+5+6)
119 = 7x + 21
7x = 98
x = 14
The second smallest integer will be x+1, so x+1 = 15.
1) Jack wants to buy a new smart phone for
£495. He has already saved £108.
Each week he earns £60.
He saves 40% of his earnings.
How many more weeks must he save for?
(4 marks)
Answer:
17 weeks
Step-by-step explanation:
Amt. of money left to save
£495 - £108 = £387
Amt. of money he saves each week
40/100 x £60 = £24
Ans: 387/24 = 16.125
= 17 weeks
16 x £24 = £384(not enough, must save one more week)
Some steps to rewrite the expression x3 − 16x + x2 − 16 as a product of three factors are shown below:
Step 1: x3 − 16x + x2 − 16
Step 2: x3 + x2 − 16x − 16
Step 3: x2(x + 1) − 16(x + 1)
Which of the following best shows the next two steps to rewrite the expression?
Step 4: (x2 + 16)(x + 1); Step 5: (x + 4)(x + 4)(x + 1)
Step 4: (x2 − 16)(x + 1); Step 5: (x + 4)(x + 4)(x + 1)
Step 4: (x2 − 16)(x + 1); Step 5: (x − 4)(x + 4)(x + 1)
Step 4: (x2 + 16)(x + 1); Step 5: (x − 4)(x + 4)(x + 1)
Answer:
third one
Step-by-step explanation:
the third one should be the answer
step 4 came out becoz of taking the common factor(x+1) and combining x2 and (-16)
Step 5 came out becoz of the theory of (a^2-b^2) = (a+b)(a-b)
ps 16 here is equal to 4^2
4. Over what interval is the function shown in the
table decreasing?
Answer:
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

1. Label all the following values using the box and whisker plot below: (1 point each)
(a) Minimum:
(b) Median (Q2):
(c) lower quartile (Q1):
(d) upper quartile (Q3):
(e) maximum:
Answer:
minimum 56
Median (Q2) 65
Lower Quartile (Q1) 60
Upper Quattile (Q3) 67
Maximum 75
Step-by-step explanation:
If you notice, there are 5 distinguished points of data, and I used all the points for each thing you asked for. You just have to recognize the minimum and maximum are the largest and smallest of all the data, and there is clearly nothing outside of the range of 56-75. then Q1, Q2, and Q3 are on the box itself. The median, just like with numbers, will always be the middle line. It is not directly in the center because there are more people in the 65-75 value range than the 56-65 value range.
hope this helps!

Does anyone know how to solve this?
Step-by-step explanation:
Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -4 to 0, it increases = [-4, 0]
For x = 2 to 5, it increases = [2, 5]
Answer: [-4, 0], [2, 5]

The perimeter of the triangle is 5x3 + 4x2 - x - 3.
Part B: What are the degree and classification of the expression obtained in Part A? (2 points)
Answer:
Part A - [tex]l_{1} + l_{2} = 5\cdot x^{2} + 7\cdot x -4[/tex], Part B - Polynomial of second degree and formed by 3 monomials, Part C - [tex]l_{3} = 5\cdot x^{3} -x^{2}-8\cdot x +1[/tex]
Step-by-step explanation:
Part A - The total length of the sides 1 and 2 is equal to the addition between respective polynomials:
[tex]l_{1} + l_{2} = (3\cdot x^{2} - 2\cdot x - 1) + (9\cdot x + 2\cdot x^{2} - 3)[/tex]
[tex]l_{1} + l_{2} = (3\cdot x^{2} + 2\cdot x^{2}) + (9\cdot x - 2\cdot x) +[(-1) + (-3)][/tex]
[tex]l_{1} + l_{2} = 5\cdot x^{2} + 7\cdot x -4[/tex]
Part B - The degree is the highest exponent of the polynomial and the classification is related to the number of monomial that make part of the algebraic expression. In this case, we conclude that resulting expression is a polynomial of second degree and formed by 3 monomials.
Part C - The length of the third side of the triangle by subtracting the expression found in part A from the polynomial of the perimeter of the triangle:
[tex]l_{3} = p - l_{1} - l_{2}[/tex]
[tex]l_{3} = (5\cdot x^{3}+4\cdot x^{2}-x-3) -(5\cdot x^{2}+7\cdot x -4)[/tex]
[tex]l_{3} = 5\cdot x^{3} + [4+(-5)]\cdot x^{2}+[(-1)+(-7)]\cdot x +[(-3)+ 4][/tex]
[tex]l_{3} = 5\cdot x^{3} -x^{2}-8\cdot x +1[/tex]
Answer:
Part A; Total length of side 1 and 2 = 5·x² + 7·x - 4
Part B; The degree of the polynomial is 2
The classification of the polynomial is a trinomial quadratic equation
Part C; 5·x³ - 4·x² - 6·x + 2
Step-by-step explanation:
The length of the sides of the rectangle are;
Side 1: 3·x² - 2·x - 1
Side 2: 9·x + 2·x² - 3
The perimeter of the rectangle is 5·x³ + 4·x² - x - 3
Part A
The given expression for the sides of the rectangle are;
Side 1: 3·x² - 2·x - 1
Side 2: 9·x + 2·x² - 3
The total length of side 1 and side 2 is given by add ing the given expressions as follows;
Total length of side 1 and 2 = 3·x² - 2·x - 1 + 9·x + 2·x² - 3 = 5·x² + 7·x - 4
Part B
The degree of the polynomial is 2 and the classification of the polynomial is a trinomial quadratic equation
Part C
Given that a rectangle rectangle consists of two pairs of equal opposite sides, we have;
The length of the third side = The perimeter - (2 × The length of side 1 + The length of side 2)
The length of the third side = 5·x³ + 4·x² - x - 3 - (2 × (3·x² - 2·x - 1) + 9·x + 2·x² - 3)
The length of the third side = 5·x³ + 4·x² - x - 3 - (8·x² + 5·x - 5)
The length of the third side = 5·x³ - 4·x² - 6·x + 2
How many moles of oxygen atoms are in 2.000 x 10^15 molecules of sulfur dioxide (SO2)?
Answer:
6.64*10^(-9) moles of oxygen.
Step-by-step explanation:
If we have N molecules, the number of moles is given by:
n = N/Nₐ
where Nₐ is the Avogadro's number:
Nₐ = 6.02214076*10^23
In 2.000*10^15 molecules of sulfur dioxide, we have:
n = (2.000*10^15)/(6.02214076*10^23) = 3.32*10^(-9) moles of sulfur dioxide.
Now, sulfur dioxide has two oxygens and a single sulfur.
Then a mole of sulfur dioxide has two moles of oxygen and a single mol of sulfur.
Then in 3.32*10^(-9) moles of sulfur dioxide, we have twice that amount moles of oxygen, or:
2*3.32*10^(-9) = 6.64*10^(-9) moles of oxygen.

The students in Mr. Leone’s class are studying rocks. The students tell Mr. Leone that several of their rocks are sedimentary. Which of the following could the students use as evidence for their thinking?
Group of answer choices
The rocks are grainy.
The rocks contain fossils.
The rocks are heavy.
The rocks have large crystals.
Answer: Hope This Helps!
Step-by-step explanation:
1: Streak: Streak is a word referring to the color of the streak that a rock makes when it is scraped against the unglazed side of a white ceramic tile (or, the unglazed bottom of a white coffee cup or toilet tank cover).
2: Luster: The luster of a mineral is best observed on a surface that is free of moisture, dirt, tarnish, and abrasion. Geologists in the field usually carry a rock hammer to break rocks so that their true luster and color can be observed.
3: They could both be the same mineral: The minerals pyrite and gold are always metallic yellow in color and streak (although they differ in other characteristics such as hardness).
4: The rocks contain fossils: Sedimentary rocks are most likely to contain fossils. Fossils are formed when the bodies or remnants of living organisms (plants and animals) are covered and are thus protected from predators or microbial decay. And thats exactly what a sedimentary rock is.

Step-by-step explanation:
Find the measure of angle 6.
Answer:
124 degree
Step-by-step explanation:
Since 9y + 7 and 4y+4 are supplementary,
9y + 7 + 4y + 4 = 180
13y + 11 = 180
13y = 180 - 11 = 169
y = 169/13
y = 13
Therefore, 9y + 7 = 9*13 + 7 = 124
4y + 4 = 4*13 + 4 = 56
Since Angle 6 and angle 9y + 7 are vertically opposite angles, they are equal.
angle 6 = 9y + 7
Angle 6 = 124

Solve each by elimination
4x - 9y = 61
10x + 3y = 25
Answer:
(4,-5)
Step-by-step explanation:
Hi there!
The problem asks us to solve by elimination, where we will add the two equations together to clear one variable, solve for the other variable, and then substitute the value of the other variable to find the value of the first variable
here's the system:
4x-9y=61
10x+3y=25
we'll clear y to start
multiply the second equation by 3
3(10x+3y)=3(25)
30x+9y=75
4x-9y=61
now add the equations together (the 9y's clear because one is positive and another is negative)
34x=136
divide by 34
x=4
the value of x is 4
now to find y:
substitute the value of x into either one of the equations to solve for y
if we were to do the first equation for example:
substitute x as 4 into the equation
4(4)-9y=61
multiply
16-9y=61
subtract
-9y=45
divide
y=-5
so the answer is x=4, y=-5. If you need it as a point, it's (4,-5)
Hope this helps! :D
