Mary has planned to save 25% of her weekly earning in savings account. She uses double number line as shown below to determine how much money she will save if she is earns $700 per week.

Answer:

$2,702.82

Step-by-step explanation:

The formula for simple interest is

I = Prt

where

I = interest amount

P = amount invested (the principal)

r = annual rate of interest

t = time in years

11.3% = 0.113 as a decimal

Now we use the formula to find the amount of interest earned.

I = $1,205 * 0.113 * 11

I = $1,497.82

The interest amount is $1,497.82.

Now we add the earned interest to the principal amount.

$1,205 + $1,497.82 = $2,702.82

Answer:

No. of balloons left with Tarun is MORE than 10

but LESS than 15.

10 < No. of balloons left with Tarun  <15

Step-by-step explanation:

this is problem of inequality . first we will try to write the existing condition in inequality form then apply other situation as given in the problem.

___________________________________________________

let the no . of balloons with Tarun be x

Given  he has is MORE than 15 balloons

thus, in equality it can be represented as

x > 15

he has LESS than 20 balloons

x < 20

combining both we have

15   < x < 20

now he gives 5 of them to sia

so we have to subtract 5 from inequality

he has left with him x-5 , let x-5 be y

thus,

subtracting 5 from each part of inequality

15  -5 < x-5 < 20 -5

10 < x-5 < 15

10 < y <15

Thus, No. of balloons left with Tarun is MORE than 10

but LESS than 15.

Step-by-step explanation:

The profit is 937.50$ The manager subtracted 25% from januarary's profit, not march's.

Answer:

2nd and 4th

Step-by-step explanation:

16.50÷6=2.75

So the second one is true.

12x2.75=33

So the fourth one is true.

Answer:

The first and fourth statements are true.

Step-by-step explanation:

We know that 6 pounds of blueberries costs $16.50 so 1 pound costs 16.5 / 6 = $2.75. Therefore, the first statement is true. The second statement can't be true because this is a direct proportion. In a direct proportion, when one variable increases, the other increases as well so the price of 2.75 pounds can't be less than the price of 1 pound. The cost of 5 pounds is 2.75 * 5 = 13.75 so the third statement is false. The cost of 12 pounds will be 2.75 * 12 = 33 so the fourth statement is true. The cost of 3 pounds is 2.75 * 3 = 8.25 so the fifth statement is false.

Answer:

B) The x-intercepts are (−5,0) and (5,0). The y-intercept is (0,25). The vertex is (0,25). The axis of symmetry is x=0. The maximum value of the function is 25.

Step-by-step explanation:

Given that the function is:

[tex]y=f(x)=-x^2+25[/tex]

It is quadratic equation, therefore we can observe that it is a parabola.

The coefficient of [tex]x^{2}[/tex] is negative, therefore it opens downwards.

That means it will have a maximum value.

This maximum value is at the vertex and where x = 0.

Also, vertex is at x intercept.

x intercept is the value of x where we have y = 0 and

y intercept is the value of y where we have x = 0

So, let us put y = 0 first.

[tex]0=-x^2+25\\ \Rightarrow x^{2} =25\\\Rightarrow x =5, -5[/tex]

Therefore x intercepts are at (5, 0) and (-5, 0)

Now, let us put x = 0,

[tex]y=0+25\\\Rightarrow y =25[/tex]

Therefore y intercept is at (0, 25).

It is the point of maximum value (which is 25) and vertex of parabola as explained above.

Kindly refer to the attached image for the graph of given function.

Therefore, correct option is:

B) The x-intercepts are (−5,0) and (5,0). The y-intercept is (0,25). The vertex is (0,25). The axis of symmetry is x=0. The maximum value of the function is 25.

Answer:

Vertex = (3,–4), y-intercept = (0,5), x-intercepts = (1,0) and (5,0), axis of symmetry is x = 3

Answer:

Step-by-step explanation:

The distance between A and M i.e JM = M - J = 5-(-19)

JM = 5+19

JM = 24

If JK:KL:KM = 2:1:3

The total ratio = 2+1+3

Total ratio = 6

Dividing each length based on ratio

length JK = 2/6 * JM

JK = 1/3 * 24

JK = 8

length KL = 1/6 * JM

KL = 1/6 * 24

KL = 4

length KM = 3/6 * JM

KM = 1/2 * 24

KM = 12

Hence the value of KM is 12

Question: In the following questions, look at different ways to represent the relation given by the equation y = x2 - 1. The table below shows some values for the given equation. Find the values of a and b.

Answer:

a= 3

b= 0

The value of a and be will be three and zero respectively.

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

We are given the quadratic equation as;

y = x² - 1

From the given table;

At x = -2, y =  (-2)² - 1 = 3

At x = -1, y = 0

At x = 0, y = -1

At x = 1, y = 0

Now, from the values above, we can say that the first graph is the correct one that shows some values for the given equation.

Therefore, values of a and be will be three and zero respectively.

The complete question is given below:-

Slope: [tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

Step 1:  Use slope formula to find the slope

[tex]m = \frac{y2 - y1}{x2- x1}=\frac{4-1}{-2-7}=\frac{3}{-9} =-\frac{1}{3}[/tex]

Therefore the slope of a line that passes through (-2, 4) and (7, 1) is [tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

2/3=4/6=6/9

your answer is 4/6,6/9

explanation

(2/3)×2=4/6

therefore 4/6 is a multiple of 2/3

(2/3)×3=6/9

therefore 6/9 is a multiple

if we comprise 4/6 & 6/9 we get 2/3

(b) 6/9 and (c) 4/6 are equivalent to 2/3

The fraction is given as:

[tex]\mathbf{Fraction = \frac 23}[/tex]

The equivalent fractions are 6/9 and 4/6, because they can be reduced to 2/3.

The proof is as follows

[tex]\mathbf{Fraction = \frac 69}[/tex]

Divide the numerator and the denominator by 3

[tex]\mathbf{Fraction = \frac{6/3}{9/3}}[/tex]

[tex]\mathbf{Fraction = \frac{2}{3}}[/tex]

Also, we have:

[tex]\mathbf{Fraction = \frac 46}[/tex]

Divide the numerator and the denominator by 2

[tex]\mathbf{Fraction = \frac 23}[/tex]

Hence, 6/9 and 4/6 are equivalent to 2/3

Answer:

Average Velocity= 70 miles per hour

Step-by-step explanation:

Distance= s

Time = t

s(t)=10t^2

Putting the values

s(2) = 10 (2)^2= 10&4

s= 40

s(5) = 10 (5)^2 = 10*25

S(5)= 250

The average velocity is defined as the rate of change of speed in unit time.

So

Speed= distance/time

Velocity = Speed in a definite direction

Average Velocity= Displacement/ Time

Average Velocity= Change in distance/ Change in time

s(5) - s(2)/ t(5)- t(2)

= 250-40/5-2= 210/3= 70 miles per hour

The first digit would go in the tens place.

Step-by-step explanation:

First we estimate the approximate numbers. For 6130 we estimate 6000 and for 153 we estimate almost 150.

So dividing 6000 by 150 would give 40 .

The four would go in the ten's place .

Now check by dividing

Answer:

The given equation is -2x^2 = -8x + 8

This can be rewritten as 2x^2 - 8x + 8 = 0

Here the value of a =2, b = -8 and c = 8

Discriminant = b^2 - 4ac

Now plug in the above values in the discriminant, we get

= (-8)^2 - 4*2*8

= 64 - 64

= 0

Here the discriminant is 0, so we will get one real root.

The discriminant is equal to 0, which means the equation has one real number solution.

Hope this will helpful.

Thank you.
