Answer:
d. The triangles are not similar
Step-by-step explanation:
The angle between the given sides is the same, so we need to compare the side ratios. In ΔQRS, we have ...
QR/RS = 4/15
In ΔVTU, we have ...
VT/TU = 8/32 = 1/4 ≠ 4/15
The triangles are not similar because corresponding sides are not proportional.

Amanda has 745 blueberries. She separated the blueberries into 5 equal groups. How many blueberries are in 2 of the groups?
Answer:
298
Step-by-step explanation:
5 equal groups of 745 would have 149 blueberries. You want to find how much is in 2 groups so you add 2 groups together, which is 149 + 149. That equals 298.
Graph the solution of this inequality:
350 > 125 + 150
10 20 30 40 50 60 70 80 90 100 110 120
Drag a point to the numb
Step-by-step explanation:
The given inequality is :
[tex]350\ge 125+15x[/tex] ....(1)
We need to draw graph of this inequality.
Subtract 125 from both sides.
[tex]350-125\ge 125-125+15x\\\\225\ge 15x[/tex]
Dividing 15 to both sides.
[tex]\dfrac{225}{15}\ge \dfrac{15x}{15}\\\\15\ge x[/tex]
Hence, the attached figure shows the graph for this inequality.

Answer: -2a,-2b
Step-by-step explanation:
find the slope of the line which is perpendicular to the line 7 x + 11 Y - 2=0
Answer:
[tex]\huge\boxed{slope=-\dfrac{7}{11}}[/tex]
Step-by-step explanation:
METHOD 1The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
We have the equation in the general form [tex](Ax+By+C=0)[/tex].
Convert to the slope-intercept form:
[tex]7x+11y-2=0[/tex] subtract 7x from both sides
[tex]11y-2=-7x[/tex] add 2 to both sides
[tex]11y=-7x+2[/tex] divide both sides by 11
[tex]y=-\dfrac{7}{11}x+\dfrac{2}{11}[/tex]
METHOD 2The general form of an equation of a line:
[tex]Ax+By+C=0[/tex]
The slope:
[tex]m=\dfrac{-A}{B}[/tex]
We have
[tex]7x+11y-2=0\\\\A=7;\ B=11;\ C=-2[/tex]
Substitute:
[tex]m=\dfrac{-7}{11}=-\dfrac{7}{11}[/tex]

A car dealership's annual sales report shows 768 vehicles were sold last year. The report revealed that 48 out of every 64 vehicles sold were SUVs. Based on the results of the report, how many of the vehicles sold were not SUVs?
Answer:
[tex]Others = 192[/tex]
Step-by-step explanation:
Given
[tex]Vehicles = 768[/tex]
[tex]SUV = \frac{48}{64}[/tex] --- Proportion of SUV
Required
Determine the number of vehicles that are not SUV
First, we calculate the number of SUV by:
[tex]SUVs= Proportion * Total\ Vehicles[/tex]
[tex]SUVs= \frac{48}{64} * 768[/tex]
[tex]SUVs= \frac{3}{4} * 768[/tex]
[tex]SUVs= \frac{3* 768}{4}[/tex]
[tex]SUVs= \frac{2304}{4}[/tex]
[tex]SUVs= 576[/tex]
Vehicles that are not SUVs is then calculated as:
[tex]Others = Total - SUVs[/tex]
[tex]Others = 768 - 576[/tex]
[tex]Others = 192[/tex]

A. y = 4x
B. 4x - y = -2
C. y = -4x + 6
D. 8x - 2y = 3
E. y = 4x + 9
•
(I think it’s either C, or D, please help I don’t understand)
Answer:
The answer is
[tex]y = - 4x + 6[/tex]
Step-by-step explanation:
Negative reciprocal for the slope.
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.
What is the equation of a perpendicular line?Let the equation of the line be y = mx + c. Then the equation of the perpendicular line that is perpendicular to the line y = mx + c is given as y = -(1/m) + d. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given as,
y = (1/4)x - 3
The slope of the line is 1/4. Then the slope of the perpendicular line will be - 4. Then the equation of the line is given as,
y = -4x + d
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.

A circle has equation x2 + y2 = 25
The circle passes through the points A, B, C and D.
Complete the coordinates for A, B, C and D.
A. (5,_)
B.(_,-5).
C. (_,0)
D(0,_)
Answer: A. (5; 0), B. (0; - 5), C. (-5; 0), D. (0; 5).
Step-by-step explanation:
A. (5; _) [x = 5; y - ?]
x² + y² = 25
5² + y² = 25
25 + y² = 25
25 + y² - 25 = 25 - 25
y² = 0
y = 0
A. (5; 0)
B. (_; -5) [x - ?; y = -5]
x² + y² = 25
x² + (- 5)² = 25
x² + 25 = 25
x² + 25 = 25
x² + 25 - 25 = 25 - 25
x² = 0
x = 0
B. (0; - 5)
C. (_; 0) [x - ?; y = 0]
x² + y² = 25
x² + 0² = 25
x² + 0 = 25
x² = 25
x = ± √25 = ± 5
C. (-5; 0) or (5; 0)
Point A has coordinates (5; 0), which means that
point C has coordinates (-5; 0).
D. (0; _) [x = 0; y - ?]
x² + y² = 25
0² + y² = 25
0 + y² = 25
y² = 25
y = ± √25 = ± 5
D. (0; - 5) or (0; 5)
Point B has coordinates (0; -5), which means that
point D has coordinates (0; 5).
10 = k + 3 + 6k
How do I solve this equation?
Answer:
k = 1
Step-by-step explanation:
[tex]10=k+3+6k\\\\10=k+6k+3\\\\10=7k+3\\\\10-3=7k+3-3\\\\7=7k\\\\\frac{7=7k}{7}\\\\\boxed{1=k}[/tex]
Hope this helps.
Answer:
K=1
Step-by-step explanation:
So first you would add the K's together.(6k+k=7k)
10=7k+3
Then you would subtract 3 from 3 and 10
7=7k
Divide 7 on both sides
k=1

Here you go. It is really easy. All you have to do is translate the points. If it says translate 3 units up, you'd pick a point, and move it up 3 units. Then do it with all the others and BOOM! You did it! Try one of the problems yourself to make sure you understand what to do next time.

Three of the vertices of quadrilateral MARY are M (-3,1), A(3,3), and R(5,7). Find the
coordinates of Y, such that, quadrilateral MARY is a parallelogram.
Use coordinate geometry to prove that MARY is a parallelogram.
9514 1404 393
Answer:
Y = (-1, 5)
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, so have the same midpoint. That is ...
(M +R)/2 = (A +Y)/2
Y = M + R - A . . . . . . multiply by 2 and subtract A
Y = (-3, 1) +(5, 7) -(3, 3) = (-3 +5 -3, 1 +7, -3) . . . . . substitute point coordinates
Y = (-1, 5)
Coordinate geometry was used to find Y that makes MARY a parallelogram. The fact that there is a solution is proof enough that MARY is a parallelogram.

showing opposite sides have the same slopeshowing opposite line segments have the same lengthGiven the method used above, both of these are unnecessary. However, in the interest of completeness, we will demonstrate.
Slope and Length of MA
slope = (3 -1)/(3 -(-3)) = 2/6 = 1/3
length = √(2²+6²) = √40
Slope and Length of AR
slope = (7 -3)/(5 -3) = 4/2 = 2
length = √(4² +2²) = √20
Slope and Length of RY
slope = (5 -7)/(-1 -5) = -2/-6 = 1/3 . . . . same as opposite side MA
length = √((-2)²+(-6)²) = √40 . . . . . . . same as opposite side MA
Slope and Length of YM
slope = (1 -5)/(-3 -(-1)) = -4/-2 = 2 . . . . same as opposite side AR
length = √((-4)² +(-2)²) = √20 . . . . . . same as opposite side AR
Opposite sides have the same slopes, so the figure is a parallelogram.
Opposite sides have the same lengths, so the figure is a parallelogram.

Step-by-step explanation:
The University of Central Florida is planning to build a new access ramp for wheelchairs at its education building. The main entrance to the building is 4 feet above the sidewalk level. The angle of elevation from where the ramp and sidewalk would meet is 8.1°. Determine the length of the ramp to the nearest tenth of a foot.
Answer:
0.6 feet
Step-by-step explanation:
We solve this question using the Trigonometric function of Tangent.
tan θ = Opposite/Adjacent.
Where:
Opposite = Height /Length of the ramp = ?
Adjacent = Distance from the base of the ramp = 4 feet
θ = 8.1°
Therefore,
tan 8.1° = x/4
Cross Multiply
x = tan 8.1 × 4
x = 0.5692843028 feet
Approximately = 0.6 feet
Length of the ramp = 0.6 feet.
round to the nearest tenth

Answer:
21.4
Step-by-step explanation:
For this problem, you only need to know that the hypotenuse (x) is the longest side of the triangle. The only answer choice longer than 20 is ...
x = 21.4
__
If you want to actually go through the numbers, you know that ...
Cos = Adjacent/Hypotenuse
cos(21°) = 20/x
x = 20/cos(21°)
x ≈ 21.4

u have to flip the reciprocal to divide by fraction so 1/10 will be just 10
Then u get 19/5 x 10
You can reduce the GCF so it would be 19 x 2
19 x 2 = 38
