Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expression is given to you is,
[tex]f(w)= 5(w+4)[/tex]
Now, if we solve the expression it can be written as,
[tex]f(w)=5w+20[/tex]
substituting the value of w, we will get,
[tex]f(9)=5(9)+20[/tex]
Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

Find the supplement of each angle. If the angle does not have a supplement, write None.
1.) 147
2.) 105
3.) 38
4.) 87
5.) 90
6.) 170
Answer:
{33, 75, 142, 93, 90, 10}°
Step-by-step explanation:
Two angles are supplementary when their sum is 180°. That means the supplement of an angle is the difference between that angle and 180°.
180° -{147, 105, 38, 87, 90, 170}° = {33, 75, 142, 93, 90, 10}°

Marcia has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest rate. the table below shows the information about the two credit cards marcia currently uses. card a card b amount $1,879.58 $861.00 apr 14% 10% monthly payment $43.73 $18.29 after 5 years, how much will marcia have saved in interest by consolidating the two balances? a. $1,526.40 b. $2,422.80 c. $105.00 d. $227.40 please select the best answer from the choices provided. a b c d
The amount Marcia saved in interest by consolidating the two balances will be $105
What will be the amount Marcia will save in interest by consolidating the two balances?It is given that
For Card A = 1,879.58 ; APR 14%; monthly = 43.73
For Card B = 861.00 ; APR 10% ; monthly = 18.29
Now [tex]\rm 5\ Years \times\ 12\ months =60\ months[/tex]
For Card [tex]A=43.73\times60=2623.80[/tex]
For Card [tex]B=18.29\times60=1097.40[/tex]
Now the [tex]\rm Total=2623.80+1097.40=3721.20[/tex]
Since Lowest APR is 10%. monthly rate: 0.83%
So the Total Card balance [tex]1879.58+861=2740.58[/tex]
[tex]A=\dfrac{P\times r(1+r)^n}{(1+r)^n} -1[/tex]
[tex]A=\dfrac{2740.58\times(0.0083(1.0083)^{60}}{1.0083^{60}}-1[/tex]
[tex]A=2740.58\times0.022[/tex]
So monthly payment.
[tex]A=60.29[/tex]
[tex]60.29\times60=3617.40[/tex]
For Separate cards: 3,721.20
For Consolidated: 3,617.40
The Difference: 103.80
Thus the amount Marcia saved in interest by consolidating the two balances will be $105

Veronica has to multiply 398 x 18. She says she can multiply 400 X 18 and then take
away one group of 18.
Write an expression that shows Veronica's thinking
Answer:
See below. Veronica's thinking is incorrect. I've included what she is thinking, but the correct thinking is more useful, as noted below.
Step-by-step explanation:
398 is 2 less than 400. Veronica needs to remove two groups of 18.I don't know what Veronica is thinking, other than:
(398 x 18) = (400*18 - 18)
She should be thinking:
(398 x 18) = (400 x 18) - (2*18). The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

From a hot-air balloon, Daniel measures a 33^{\circ} ∘ angle of depression to a landmark that’s 1579 feet away, measuring horizontally. What’s the balloon’s vertical distance above the ground? Round your answer to the nearest tenth of a foot if necessary.
The balloon’s vertical distance above the ground is 860.0 ft
Right angle triangle:Right angle triangle are triangle that has one of its sides as 90 degrees. The side of the triangle can be found using trigonometric ratios. Therefore,
The horizontal distance from the landmark tot he hot balloon is 1579 feet and it is the hypotenuse side of the triangle formed. Therefore, the vertical height is the opposite sides.
Using trigonometric ratio,
sin 33° = opposite / hypotenuse
sin 33° = x / 1579
cross multiply
x = 1579 × sin 33
x = 1579 × 0.54463903501
x = 859.985036289
x = 860.0 ft

Group A and Group B were randomly sampled from the same population. A double box plot showing group A on the top and group B on the bottom. For group A, the left end mark is at 1, the left edge of the box is at 3, the line inside the box is at 4, the right edge of the box is at 5, and the right end mark is at 7 point 5. For group B, the left end mark is at 3, the left edge of the box is at 4, the line inside the box is at 5, the right edge of the box is just past 5, and the right end mark is at 7 point 5. Select all the inferences that you can make. Group B has a higher median than Group A. Group B has a higher mean than Group A. Group B has more overall variability than Group A. Group B has a smaller range than Group A. Group A and B have the same maximum value
We can conclude the following about the box plots:
Group A had lower median than group B. Group B has less overall variability because it has a smaller range than group A.What is Median and Range of a Data Set?Median is the middle value which is represented by a vertical line that divides the rectangular box in a box plot.
Median for Group A is smaller than the median of Group B.
Range of a data set is the difference between the maximum value and the minimum value. Range is a measure of variability. The bigger the range, the more the variability and vice versa.
Range of Group A is larger than range of Group B.
Therefore, we can conclude the following about the box plots:
Group A had lower median than group B. Group B has less overall variability because it has a smaller range than group A.Learn more about median and range on:

An ellipse has vertices along the major axis at (0, 1) and (0, −9). The foci of the ellipse are located at (0, −1) and (0, −7). The equation of the ellipse is in the form below.
Which is a correct value for one of the variables shown in the equation?
a = 10
b = 4
h = 3
k = 0
Answer:
A. A=10
Step-by-step explanation:
you’re welcome
The equation of the ellipse is required \frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1
The required equation is
[tex]\frac{x^2}{16} +\frac{(y+4)^2}{25}=1[/tex]
It can be seen that the major axis is parallel to the y axis.
The major axis points are
[tex](h,k+a)=(0,1)\\(h,k-a)=(0,-9)\\k+a=1\\k-a=-9[/tex]
Subtracting the equations
[tex]2a=10\\\implies a=5[/tex]
The foci are
[tex](h,k+c)=(0,-1)\\(h,k-c)=(0,-7)[/tex]
[tex]k+c=-1\\k-c=-7[/tex]
Subtracting the equations
2c=6
c=3
k+c=-1 implies that k=-1-c
k=-1-3
k=-4
What is the equation of the ellipse?[tex]\frac{(x-h)^2}{b^2} +\frac{(x-h)^2}{a^2}=1[/tex]
So we get,
[tex]\frac{(x-0)^2}{4^2} +\frac{(y+4)^2}{5^2}=1[/tex]
[tex]\frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1[/tex]
Therefore the equation is, [tex]\frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1[/tex].
