Answer:
The number is either 95 or 59
Step-by-step explanation:
The two digit number would be;
(10a + b)
The reversal will be (10b + a)
The sum of the two is 154
(10a + b ) + (10b + a) = 154
11a + 11b = 154
11(a + b) = 154
a + b = 14 ••••••••(i)
The difference between the two digits is 4
Let’s have this as;
a - b = 4 ••••(ii)
from ii;
a = 4 + b
Substitute this into equation i
4 + b + b = 14
2b = 14-4
2b = 10
b = 10/2
b = 5
Recall;
a = b + 4
a = 5 + 4
a = 9
So we have the number as 95 or 59

Answer:1152 miles
Step-by-step explanation: we know he can drive 384 in 6 hours so if we multiply 6 by 3 its 18 so we must multiply 384 by 3 and the answer would be 1152
What percent df 160 is 56? Use the percent bar model.
Answer:
35%
i think
Step-by-step explanation:
Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)
Answer:
[tex]Pr = 0.59049[/tex]
Step-by-step explanation:
See Comment for Complete Question
Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).
However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)
The probability of selecting a number other than 4 in each of the digit is:
[tex]1st \to \frac{9}{10}[/tex]
[tex]2nd \to \frac{9}{10}[/tex]
[tex]3rd \to \frac{9}{10}[/tex]
[tex]4th \to \frac{9}{10}[/tex]
[tex]5th \to \frac{9}{10}[/tex]
So, the required probability is:
[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]
[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]
[tex]Pr = \frac{9^5}{10^5}[/tex]
[tex]Pr = \frac{59049}{100000}[/tex]
[tex]Pr = 0.59049[/tex]
Tony bought a computer. He paid $450.00 plus sales tax. The sales tax
was 6%. How much did he pay in sales tax?
Answer:
$27
Step-by-step explanation:
We have to find 6% of $450. We can make an expression and solve it:
6/100•450
We can cancel out factors now:
3/50•450
Now we'll cancel out 50 and 450:
3x9=$27
And that's your answer! Hope this helps =)
Is this proportional or non proportional and why
Given:
The table of values.
To find:
Whether the given relation in the table is proportional or non proportional.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
It means the ratio of y and x remains same for proportional relation.
From the given table, the points are (10,18), (11,18.6) and (12,19.2). The ratio of y to x for these points are:
[tex]\dfrac{18}{10}=1.8[/tex]
[tex]\dfrac{18.6}{11}\approx 1.69[/tex]
[tex]\dfrac{19.2}{12}=1.6[/tex]
Since the ratio of y to x for the given points are not equal, therefore the given relation is a non proportional relation.
Given the three functions: f(x)=4(2) g(x)=8x² + 24x , and h(x)= 4x + 8
Label each function as quadratic, linear, or exponential.
f(x)=
g(x)=
h(x)=
Answer:
f(x)=exponential
g(x)= quadratic
h(x)= linear
Step-by-step explanation:
exponential function
[tex] {ab}^{x} [/tex]
Quadratic function
[tex]a {x}^{2} + bx + c[/tex]
Linear function
[tex]y = mx + c[/tex]
Hi there!
[tex] \large \boxed{ y = {a}^{x} \: \: (a \neq 0, \: a > 1)}[/tex]
The equation above is an exponential family type.
[tex] \large \boxed{y = a {x}^{2} + bx + c \: \: (a \neq 0)}[/tex]
The equation above is quadratic type.
[tex] \large \boxed{ y = mx + b}[/tex]
The last type above is a linear type.
Hence, the answers are:

f(x) = x2. What is g(x)?
Answer:
B
Step-by-step explanation:
Graph shrinks, that means for every x value there is a higher y value. So coefficient of x is definitely more than 1. Try to substitute x = 1 to (9x)^2 and (3x)^2.
(3(1))^2 = 9

3) Using your graphing calculator, create a graph of the function f(x) = x2 + 4x + 3 What is the vertex? What are the roots? What is the equation of the axis of symmetry?
Answer:
Step-by-step explanation:
Input the function f(x) = x^2 + 4x + 3 and graph it (using the calculator) for the interval [-5, 5]. The roots are the x values at which this graph crosses the x axis and are {-3, -1). The axis of symmetry is the vertical line through x = -2.

Step-by-step explanation:
A certain television is advertised as a 85 inch TV if the width of the TV is 67 how tall is the TV
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorem:
85^2 = 67^2 + h^2, where h is the height of the TV
Then 7225 = 4489 + h^2, or
h^2 = 2736, or h = +√2736 = 52.3 inches
The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
A certain television is advertised as a 85 inch TV
It means the diagonal length is 85 inches.
Width of the TV = 67 inches
Let's suppose the TV is x inches Tall
So from the Pythagoras theorem:
[tex]\rm 85^2 = x^2+67^2[/tex]
7225 = x² + 4489
x = 52.30 inches
Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

Answer:
y = -2x + 5 [ 1st option ]
Step-by-step explanation:
Consider any two points , say
(1,3) (2,1)Firstly let's find the slope of the line as ,
=> m = y₁ - y₂ / x₁ - x₂
=> m = 3-1 / 1-2
=> m = 2/-1
=> m = -2
Third point is, (3 , -1) . Using slope point form .
=> y - y₁ = m ( x - x₁ )
=> y - (-1) = -2( x - 3)
=> y + 1 = -2x +6
=> y +2x +1-6=0
=> y +2x -5 = 0
=> y = -2x + 5
On looking at options first one is correct
Hence the equation of line is y = -2x + 5.PLEASE MAKE ANSWER CLEAR

Priya makes bracelets for her online store. Her monthly business expenses are $520. She sells an average of 80 bracelets per
month. Based on the inequality below, if she wants to profit at least $1,240, how much should she charge, b, per bracelet?
80b - $520 > $1,240
A. Priya needs to charge at most $19 per bracelet.
B. Priya needs to charge at least $22 per bracelet.
C. Priya needs to charge at most $22 per bracelet
D. Priya needs to charge at most $29 per bracelet.
Answer:
B
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = 80 x b
total cost = 520
the profit has to be at least $1240
80 x 22 = 1760
1760 - 520 = 1240
b is correct

Can some one find the vertex for g(x)8x^2-14x+3 Using decimals if necessary
[tex]x_{v}[/tex]Answer:
The vertex of an up - down facing parabola of the formy = ax" + bx + c is xy =
The parabola params are:
a = 8, b = -14, c =3
[tex]x_{v}=b/2a[/tex]
[tex]x_{v}[/tex]=-(-14)/2·8
simplify
[tex]x_{v}[/tex]=-(-14)/2·8
[tex]x_{v} = 7/8[/tex]
Plug in [tex]x_{v}[/tex]=7/8to find the [tex]y_{v}[/tex] value
[tex]y_{v}[/tex]= -25/8
Therefore the parabola vertex is
(7/8 , -25/8)
If a < 0, then the vertex is a maximum value
If a > 0, then the vertex is a minimum value
a = 8
Minimum(7/8 , -25/8)
