Brad wants to buy flowers for his friend
with $33. The daisies are $1 each and
the roses are $2 each. He buys 3 more daisies than roses.
how much did the roses cost?
Answer:
20
Step-by-step explanation:
Answer:
20$ For the Roses
Step-by-step explanation:
Think about it like this. For each daisy (1$), the price is double for roses (2$).
Brad has a limit of 33$. And he bought 3 more daisies than roses.
If each daisy is 1$, and he bought 3+ over roses, take away 3$ to get 30$. If he bought 10 (excluding 3+) Daisies, He must have bought 10 roses.
(10 Daisies = 10$) + (10 Roses = 20$) = 30$
30$ + (3 Daisies = 3$) = 33$
If 22% of high school students say they eat out 3 times a week, how many students of the 2346 students who attend WHS would you expect eat out 3 times a week?
Answer:
516 students eat out 3 times a week
Step-by-step explanation:
22% of 2346 is 516.12 and a person can't be a decimal so it's 516
22 x 2346 = 51612
and 51612÷100 = 516.12
We would expect about 516 WHS students to eat out 3 time
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that 22% of high school students say they eat out 3 times a week
We need to find the number of students of the 2346 students who attend WHS would you expect eat out 3 times a week
We can start by using the proportion:
(22/100) = (x/2346)
where x is the number of students we would expect to eat out 3 times a week.
To solve for x, we can cross-multiply:
100x = 22 × 2346
100x = 51612
Divide both sides by 100
x = 516.12
Hence, we would expect about 516 WHS students to eat out 3 time

Margo borrows $600, agreeing to pay it back with 7% annual interest after 8 months. How much interest will she pay?
The interest which has to be paid is $28.
Simple Interest amount can be estimated by the product of principal amount, rate of interest, and time in year.
Simple Interest= S.I. =p*t*r/100
where p is the principal amount,
r: interest rate (%)
t: the time (in year).
Here, given,
Margo has taken borrowed $600 with an annual interest of 7% which has to be paid within 8 months.
principal amount P = $600
rate of interest= r=7%
time=t=8 months= 2/3 year

if angle X is an acute angle with tan X = 8/7, what is the value of sec X?
Answer: [tex]\frac{\sqrt{113}}{7}[/tex]

As X is an acute angle, all 6 trigonometric functions with an argument of X are positive.
Using the identity [tex]1+\tan^{2} X=\sec^{2} X[/tex],

f(x)=x2 what is g(x)
Answer:
-x^2-2
Step-by-step explanation:
So by looking at the two curves it appears that g(x) is simply a reflection of f(x) over the x-axis and then shifted 2 units down. So to reflect the parabola you simply make the x^2 negative to get -x^2 and then to go 2 units down you subtract 2 from the -x^2. This gives you the equation

Figure M and it’s congruent image, figure N, are graphed on the coordinate plane below.
Describe a sequence of transformations that will take figure M onto its congruent image, figure N.
EXPLAIN THE ANSWER!!
The reflection over the line y = x - 3 will take figure M onto its congruent image, figure N.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
As we can see in the graph there are two shapes are shown.
Figure M and Figure N
The sequence of transformations that will take figure M onto its congruent image, figure N is:
First, we need to draw a line that passes through (3, 0) and (0, -3)
The equation of the line is:
[tex]\rm y+3=\dfrac{\left(-3\right)}{-3}\left(x\right)[/tex]
y + 3 = x
y = x - 3
The reflection over the above line will take figure M onto its congruent image, figure N.
Thus, the reflection over the line y = x - 3 will take figure M onto its congruent image, figure N.

The width of a rectangle is 15 centimeters less than its length. If the area of the
rectangle is 100 square centimeters, find the length and the width using the formula
A = lw.
O Length = 25 centimeters and Width = 10 centimeters
○ Length = 20 centimeters and Width = 5 centimeters
O Length = 115 centimeters and Width = 100 centimeters
○ Length = 5 centimeters and Width = 20 centimeters
Answer:
○ Length = 20 centimeters and Width = 5 centimeters
Step-by-step explanation:
Let the length = L
Then the width is L - 15
A = lw
100 = L(L - 15)
L² - 15L - 100 = 0
(L - 20)(L + 5) = 0
L - 20 = 0 or L + 5 = 0
L = 20 or L = -5
Since a length of a rectangle cannot be negative, we discard the solution L = -5 and keep the solution L = 20.
L = 20
width = L - 15 = 20 - 15 = 5
Answer: ○ Length = 20 centimeters and Width = 5 centimeters

Answer:
the interior angle of a triangle = 180- 89 ( forming linear pair)
= 91°
y = 91 + 23
Y = 114° ( sum of interior angle of a triangle ls equal to its outer angle)
Answer:
114
Step-by-step explanation:
Angle A + 89 = 180 (Sum ofAngles in a straight line)
Angle A = 180 - 89 = 91
Angle B + Angle A + 23 = 180 (Sum of angles in a triangle)
Angle B + 91 + 23 = 180
Angle B = 180 - 114 = 66
Angle B + y = 180 (Sum of angles in a straight line)
66 + y = 180
y = 180 - 66 = 114
