Answer:
5 × Y = 45 y stands for "a number"
Step-by-step explanation:
not sure what your asking so ill solve it too
45/5=9
when the equation is multiplication you use division also vice versa for division
5×9=45
y=9
f(-2) when f(x)=25x-4
Answer:
25x4 - 2
Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : 2 is not a square !!

giving brainliest for who gets it right
Answer:
[tex]35[/tex]
Step-by-step explanation:
From the information given we can solve for x using the larger triangle
we know that the angle at the top is 45 degrees and the side opposite of it is 35, in other words we need to find the adjacent, or rather, x
Since we have angle, an opposite side, and we need the adjacent. The trig function we need to use is [tex]tan[/tex], the formula is
[tex]tan0[/tex][tex]=\frac{opposite}{adjacent}[/tex]
we need to rearrange this to solve for the adjacent
[tex]adjacent=\frac{opposite}{tan(0)}[/tex]
[tex]x=\frac{15}{tan(45)}[/tex]
[tex]x=35[/tex]
plz mark me brainliest. :)
Solve for x, round to the nearest tenth.

2x=48
x=24
K=24
B=21
Answer:
24
Step-by-step explanation:
So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

2x=180-22
2x=158
x=79
Answer:
79
Step-by-step explanation:
The two lines on the side of the triangles indicates that the opposite angles are equal to each other.
180-22=158
158/2=79 so f = 79

A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in six seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
Answer:
0 sec. I help him get the tourist too :)
Step-by-step explanation:
jk, but her cub takes 13 and the mama 4
Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are as follows:
Together rate: 1/6.Mama's rate: 1/x.Cub's rate: 1/(x + 9).Hence:
[tex]\frac{1}{x} + \frac{1}{x + 9} = \frac{1}{6}[/tex]
[tex]\frac{x + 9 + x}{x(x + 9)} = \frac{1}{6}[/tex]
[tex]x^2 + 9x - 12x - 54 = 0[/tex]
[tex]x^2 - 3x - 54 = 0[/tex]
Quadratic equation with coefficients [tex]a = 1, b = -3, c = -54[/tex], hence:
[tex]\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-54) = 225[/tex]
[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{3 + \sqrt{225}}{2} = 9[/tex]
[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{3 - \sqrt{225}}{2} = -6[/tex]
It would take each bear 9 hours to open the car door alone.

A pair of pants originally cost 25 dollars but costs 45 dollars. what is the percent markup? Please help!
Answer:
The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
How do you calculate a 45 markup?
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

1.4 pounds of almonds, 0.8 pound of cashews, and 2.6 pounds of peanuts. How much does Mila spend in all
Answer:
the total amount spent is $31.68
Step-by-step explanation:
The computation of total amount spent as follows:
= 1.4 pounds × $9.15 + 0.8 pounds × $10.75 + 2.6 pounds × $3.95
= $12.81 + $8.6 + $10.27
= $31.68
hence, the total amount spent is $31.68
We simply apply the pounds with its price
6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)
Solve the equation.
3x + 2(4x − 6) = 8x + 1

add the males and females. then divide the males by the sum(290). and that's r answer.
Answer:
53%
Step-by-step explanation:
The easiest way to start this is to add the two values together to find the total amount of participants.
154+136=292
To find the percentage of males in the population, we need to divide the amount of men by the total population.
154/292=0.527397
The percentage of men is 53%.

find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.
1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.

The table shows the monthly snowfall in Kyburz, California, and Park City, Utah.
What conclusion can you draw from the given data?
A. Because the interquartile range of the data for Kyburz is higher than the interquartile range of the data for Park City, the variability in the monthly snowfall is higher in Kyburz.
B. Because the interquartile range of the data for Kyburz is lower than the interquartile range of the data for Park City, the variability in the monthly snowfall is lower in Kyburz.
C. Because the mean of the monthly snowfall values in Kyburz is higher than the mean of the monthly snowfall values in Park City, the variability in the monthly snowfall is higher in Kyburz.
D. Because the mean of the monthly snowfall values in Kyburz is lower than the mean of the monthly snowfall values in Park City, the variability in the monthly snowfall is lower in Kyburz.
Answer: A) Because the interquartile range of the data for Kyburz is higher than the interquartile range of the data for Park City, the variability in the monthly snowfall is higher in Kyburz.
