Answer:
The HCF of 130, 325 and 845 is equal to 65.
Step-by-step explanation:
We need to find the HCF of 130, 325 and 845.
First, we see the prime factors of the above numbers i.e.
The factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
The factors of 325 are: 1, 5, 13, 25, 65, 325
The factors of 845 are: 1, 5, 13, 65, 169, 845
Then the greatest common factor is 65. So, the HCF of 130, 325 and 845 is equal to 65.
which equation is represented by the phrase a number increased by 3 equals 10

Answer:
27.4
Step-by-step explanation:
Use your calculator for this.
Remember, use SOH CAH TOA
We have an opposite (O) and an adjacent side (A), so we use SINE
sin(41)=18/X......following?
Now, solve for X by multiplying both sides by X......sin(41)(X)=18
Then, divide both sides by sin(41).
Type into your calculator: 18/sin(41), and you'll get 27.44. Round to the nearest tenth, or 27.4!
Answer:
x = 11.8
Step-by-step explanation:
sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 41 = [tex]\frac{18}{x}[/tex]
⇒ 0.656 = [tex]\frac{18}{x}[/tex]
multiply 18 on both sides:
⇒ 0.656 x 18 = [tex]\frac{18}{x}[/tex] x 18
⇒ 11.808 = x
round to the nearest tenth:
⇒ 11.808 = 11.8

Describe where the line of reflection is in this picture.
Answer:
the line is in the grass because it divides and reflects the sky and mountain.
Answer:
The line of reflection in the picture above is on the x-axis.
Step-by-step explanation:
The line of reflection is the mirror line; the line across which a figure is "flipped" and in this case, the line of reflection is on the x-axis.

John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
sample response: The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.
Step-by-step explanation:
Jay bought 6 tubs of kutsinta at P70 per tub plus a delivery charge of P30. How much will she pay for her order?
Answer:
the total amount paid by her is P450
Step-by-step explanation:
The computation of the total amount paid by her is given below;
= Total cost + delivery charges
= 6 tubs at P70 + P 30
= P420 + P30
= P450
Hence, the total amount paid by her is P450
A membership at Gisele’s Gym costs $145 to join and $3 for each visit. A membership at Freddie’s Fitness costs $75 to join and $5 for each visit. Which location has a lower total cost for different numbers of visits? Write each number of possible visits from the box into the correct column in the table to show whether one location has a lower total cost, or the same total cost as the other location.
Step-by-step explanation:
You can do the equation 145+3v for Gisele’s Gym
For Freddie’s Fitness do the equation 75+5v and put in the number of visits for v
For example, for 33 visits Freddie’s fitness has a lower cost than Gisele’s gym. You could do 3x33 + 145 = ? for Gisele’s gym, and do 5x33 + 75 for Freddie’s Fitness, and then compare which one has a lower cost. But technically I just gave you one answer and shown you what you could do.
I’m not particularly sure if I’m correct but that’s how I would do it, sorry for the long wait, if you have any questions you can ask me :)

Answer:
Yes, Nan pays $25 more
Step-by-step explanation:
144 hours /24 hours per day = 6 days exactly
$50 + (5 x $25) = $175
145 hours 24 hours per day = 6 days and one hour (must pay for 7 days)
$50 + (6 x $25) = $200
$200 - $175 = $25 more
Is the expression
3/4a (16b + 24) equivalent to 12ab + 18a?
SHOW YOUR WORK
Answer:
Yes they are equivalent.
Step-by-step explanation:
since 16 times 3/4 is 12 and a times b is ab. Put those together and you get 12ab. Since 3/4 of 24 is 18 and the variable is a, it is 18a. Hope this helped.

A new Playstation game system costs $380. The tax on the system is 4%. What is the total cost of the system including tax? *
Answer:
395.2
Step-by-step explanation:
380 x 0.04 = 15.2
380 + 15.2 = 395.2
Answer:
The cost of the system including the tax is $395.20.
Step-by-step explanation:
If the tax is 4% that means that the total price will equal...
380 + (380)(0.04) = $395.20
Therefore the cost of the system including the tax will be $395.20.
Which of the following is a solution of x^2+6x=-18
We are provided with a quadratic equation , and we have to find it's roots , but let's recall some things
The Standard Form of a quadratic equation is ax² + bx + c = 0 If D > 0 , then the equation have two real and distinct roots/zeroes . If D = 0 , then the equation have two equal roots/zeroes .If D < 0 , then the equation have two imaginary roots/zeroes or you can say that no real rootsWhere , D is the Discriminant whose value is b²- 4ac and the roots of the equation are given by a very famous formula called The Quadratic Formula , which is as follows ;
[tex]{\quad {\boxed{\pmb{\bf x = \dfrac{-b \pm \sqrt{D}}{2a}}}}}[/tex]
Now , coming back on the question ;
We are provided with the equation x² + 6x = -18 , so on comparing this equation with the standard form of quadratic equation , we have , a = 1 , b = 6 and c = 18 . Now calculating the Discriminant ;
[tex]{: \implies \quad \sf D=(6)^{2}-4\times 1 \times 18}[/tex]
[tex]{: \implies \quad \sf D=36-72}[/tex]
[tex]{: \implies \quad \sf D=-18}[/tex]
As , D < 0 , so two imaginary roots exist . Now by quadratic formula ;
[tex]{: \implies \quad \sf x=\dfrac{-6 \pm \sqrt{-36}}{2\times 1}}[/tex]
[tex]{: \implies \quad \sf x=\dfrac{-6 \pm \sqrt{\underline{6\times 6}\times -1}}{2}}[/tex]
[tex]{: \implies \quad \sf x=\dfrac{-6 \pm 6\sqrt{-1}}{2}}[/tex]
[tex]{: \implies \quad \sf x=\dfrac{-6 \pm 6\iota}{2} \quad \{\because \sqrt{-1}=\iota\}}[/tex]
[tex]{: \implies \quad \sf x=\dfrac{2(-3\pm 3\iota)}{2}}[/tex]
[tex]{\quad \qquad \boxed{\bf \therefore \: x=-3 \pm 3\iota}}[/tex]
The function y= -0.2 + 0.5 represents the percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer.
A. Identify and intercept the x- intercept
B. Identify and intercept the y-intercept
Answer:
A
Step-by-step explanation:
intercept the x- intercept
Answer:
Step-by-step explain
x-intercept: 2.8 hours
y-intercept: 0.7 . . . . fraction of power remaining
Step-by-step explanation:
The equation is in slope-intercept form, so the y-intercept can be read directly: 0.7.
To find the x-intercept, set y=0 and solve for x:
0 = -0.25x +0.7
0.25x = 0.7 . . . . . add .25x
x = 2.8 . . . . . . . . . multiply by 4 (that is, the reciprocal of 0.25)
The x-intercept is 2.8; the y-intercept is 0.7.

need help with questions 15 and 16 please
Answer:
#15: y = -5x -4
#16: y = 2/5x -4
Step-by-step explanation:
Lets start with #15:
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx -4
Pick another point and substitute its x and y values in this equation.
I chose (-1,1) and substituted as 1 = m(-1) -4
Isolate m:
1 + 4 = -m - 4 + 4
5 = -m
m = -5
The Equation in Slope Intercept Form is y = -5x -4
Let's do #16.
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx - 4
Pick another point and substitute its x and y values in this equation.
I used Fractional Points as Whole ones were not seen.
I chose (5/2,-3) and substituted as -3 = m(5/2) - 4
Isolate m:
-3 + 4 = 5m/2 - 4 + 4
1= 5m/2
m=2/5
The Equation in Slope Intercept Form is y = 2/5x - 4
