Answer:
Joe's present age = 36 years
Vika's present age = 20 years
Step-by-step explanation:
Let us represent the present age of
Joe = x
Vika = y
Joe's age exceeds by Vika's age by 16 years.
x = y + 16...... Equation 1
Four years ago, Joe was twice as old as Vika.
x - 4 = 2(y - 4)
x - 4 = 2y - 8........ Equation 2
We substitute y + 16 for x
y + 16 - 4 = 2y - 8
Collect like terms
16 - 4 + 8 = 2y - y
y = 20 years
We solve for x
x = y + 16...... Equation 1
x = 20 + 16
x = 36 years
Therefore, Joe's present age = 36 years
Vika's present age = 20 years

Which inference is valid?
A
Factory B produced more tires than factory A because factory B has a median of 112 and factory A has a median of 102
B
Factory B has less variability in production because the range for factory B is smaller than the range for factory A.
с
Factory A has less variability in production because the range for factory A is greater than the range for factory B.
D
Factory B produced more tires than factory A because factory Bhas a mean of 109 and factory A has a mean of 104.2.
A map has a scale of 3 cm and 20 cm which statement is true or false two cities are actually 66 cm part are9.9 cm part
Find m<6 if m<8 = 112°
Reason:
Angle 6 and angle 8 are corresponding angles because they are in the same southeast corner of their four-corner angle configuration. Corresponding angles are congruent when we have parallel lines like this.
To prove the circles are similar, which sequence of transformations will map circle A with center (-5, -4) and radius 18 to circle M with center (-2, 3) and radius 6?
Question 15 options:
Translate <3, 7> then dilate by scale factor of 3
Translate <-3, -7> then dilate by scale factor of 3
Translate <-3, -7> then dilate by scale factor of 1/3
Translate <3, 7> then dilate by scale factor of 1/3
Answer:
Translate <3, 7> then dilate by scale factor of 1/3Step-by-step explanation:
-2 - (-5) = 3
3 - (-4) = 7
6/18 = 1/3
The sequence of transformation that will map the circle would be:
D). Translate <3, 7> then dilate by a scale factor of 1/3
Define dilationDilation is denoted as the process in which an object gets expanded or widened.
Given that,
Center of circle A = (-5, -4)
Radius = 18
Center of circle M = (-2,3)
To find the dilation,
⇒ [tex]-2 - (-5) = 3[/tex]
⇒ [tex]3 - (-4) = 7[/tex]
= [tex]6/18[/tex]
[tex]= 1/3[/tex]
Therefore, the translation will happen with <3, 7> and the dilation in the scale factor being 1/3.
Thus, option D is the correct answer.

solve for sk and angle PQR.
Answer:
arc SK = 144°
∠PQR = 60°
Step-by-step explanation:
∠M = 1/2 (arc SK - arc NL)
37° = 1/2 (arc SK - 70°)
arc SK = 2*37° + 70° = 144°
∠PQR = 1/2 (small arc PQ) = 1/2 (360° - 240°) = 60°

The required number of the combination is 384. Option C is correct.
A menu at a local diner has 12 appetizers, 8 entrees, and 4 choice of desserts. How many different meal combinations are possible when you select one appetizer, one entrée, and one dessert from the menu is to be determined.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
For 12 appetizers, 8 entrees, and 4 choices of desserts.
The number of composite combinations that can be made = 12 * 4 * 8
= 384
The required number of the combination is 384. Option C is correct.

Quadrilateral MNPQ is shown on the grid below.
What is the area, in square units, of the quadrilateral?
A) 182 square units
B) 4550 square units
C) 9100 square units
D) 91 square units
Answer:
42 square units
Step-by-step explanation:
Find the diagram attached
Area of the diagram = Area of the triangle + Area of rectangle
Area of rectangle = Length * Width
Area of rectangle = 3 * 6
Area of rectangle = 18 square units
Area of triangle = 1/2 * base * height
Get the base of the tringle using the pythagoras theorem;
b^2 = 10^2-6^2
b^2 = 100 - 36
b^2 = 64
b = 8units
height = 6 units
Area of the triangle = 1/2 * 8 * 6
Area of the triangle = 48/2
Area of the triangle = 24 square units
Area of the figure = 18+24
Area of the figure = 42 square units

Find the equation of the line that contains the point (-4, -4) and is perpendicular to the line 4x+5y=5
Answer:
[tex]5x-4y+4=0[/tex]
Step-by-step explanation:
Given: A point which is perpendicular to the line .
To find: The equation of the line which passes through [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex].
Solution:
We have, [tex]4x+5y=5[/tex].
Slope of the line [tex]4x+5y=5[/tex] is [tex]-\frac{4}{5}[/tex].
The line which passes through [tex](-4, -4)[/tex] is perpendicular to the line [tex]4x+5y=5[/tex].
Now, the product of the slopes of two perpendicular lines is [tex]-1[/tex].
Therefore, [tex]m\times-\frac{4}{5}=-1[/tex]
So, its slope is [tex]\frac{5}{4}[/tex].
Now, the equation of the line which passes through [tex](-4, -4)[/tex] and slope [tex]\frac{5}{4}[/tex] is:
[tex]y-(-4)=\frac{5}{4} [x-(-4)][/tex]
[tex]\Rightarrow y+4=\frac{5}{4} (x+4)[/tex]
[tex]\Rightarrow 4(y+4)=5(x+4)[/tex]
[tex]\Rightarrow 4y+16=5x+20[/tex]
[tex]\Rightarrow 5x-4y+20-16=0[/tex]
[tex]\Rightarrow 5x-4y+4=0[/tex]
Hence, the equation of the line that contains the point [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex] is [tex]5x-4y+4=0[/tex].

The distance travelled by a delivery vehicle can be calculated by the equation Distance = Rate x Time. What would be the correct representation of a situation in which a driver doubles his original speed, but drives for only of the original amount of time? dn = new distance do = original distance
Answer:
New distance = 2do
Step-by-step explanation:
The distance equation :
Distance = speed * time
If speed is doubled ; time stays the same
If speed is doubled,; new speed becomes
Doubled speed = 2* speed
Time remains the same ;
Hence,
New distance becomes : 2 * speed * time
Original dista, Speed * distance
New distance, dn = 2*do = 2do
