In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given. Find the sum of the shapes in the fourth row
Answer:
26
Step-by-step explanation:
2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26
The sum of the shapes in the fourth row is 24 and this can be determined by using the arithmetic operations and by forming the linear equations.
Given :
In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given.
Let the symbol of the circle be denoted by 'x', square be denoted by 'y', and triangle be denoted by 'z'.
Now, the linear equations that represent the given diagrams are:
2y + 3x = 31 --- (1)
y + 2x + 3z = 27 --- (2)
3y + x + z = 24 --- (3)
Now, evaluate equation (1) for 'y'.
[tex]\rm y=\dfrac{31-3x}{2}[/tex] --- (4)
Now, substitute the value of y in equation (2).
[tex]\rm \dfrac{31-3x}{2}+2x+3z=27[/tex]
31 - 3x + 4x + 6z = 54
6z = 23 - x
[tex]\rm z = \dfrac{23-x}{6}[/tex] --- (5)
Now, substitute the value of 'y' and 'z' in equation (3).
[tex]3\times \dfrac{31-3x}{2}+x+\dfrac{23-x}{6}=24[/tex]
[tex]279-27x+6x+23-x=144[/tex]
158 = 22x
[tex]x = \dfrac{79}{11}[/tex]
Now, substitute the value of x in equations (4) and (5).
[tex]\rm z = \dfrac{23-\dfrac{79}{11}}{6}[/tex]
[tex]z = \dfrac{29}{11}[/tex]
[tex]\rm y=\dfrac{31-3\times \dfrac{79}{11}}{2}[/tex]
[tex]y=\dfrac{52}{11}[/tex]
The last equation is written in terms of x, y, and z as:
= 3y + x + w
Now, substitute the value of known terms in the above equation.
[tex]=3\times \dfrac{52}{11}+\dfrac{79}{11}+\dfrac{29}{11}[/tex]
[tex]=\dfrac{156+79+29}{11}[/tex]
= 24

Arturo is driving at a speed of 50 miles per hour. At 2:00 he
sees the following sign.
Applebee
11 miles
Beauville
41 miles
Caanan
62 miles
Denton
98 miles
Arturo continues at the same speed. At 2:30 how far from
Caanan will he be?
A.
12 miles
B.
16 miles
C.
25 miles
D.
26 miles
E.
37 miles
Answer:
Your answer is 37
Step-by-step explanation:
Caanan is 62 miles away and since he drives at 50 miles per hour, and if it is 2:30 then 30 minutes is half a hour, which means you divide 50 in half by 2 and get 25. After you do that then you subtract 62 and 25 to get your answer 37. Have a good day!!! :)

Would you use SSS or SAS to prove the triangles congruent? If there is not enough information to prove by SSS or SAS, then write “not enough information” and explain why.
These triangles are congruent under the SAS congruence criterion. We can prove it using the following steps :
Given :
In triangle 1 and 2 :
A side in triangle 1 and a side in triangle 2 are equal.Another side in triangle 1 and triangle 2 is equal. The angle between the equivalent sides is also equal.Since the SAS congruence criterion says that two triangles are congruent if two of their sides and one included angle is equal and since these 2 triangles fulfill all of those rules, we can conclude that these triangles are congruent under the SAS congruence criterion.

HW HELP ASAP GRAPHS PLZ
Answer:
Step-by-step explanation:
Slope intercept form of a line is
y=mx+b, where m=slope and b=y intercept
m=(y2-y1)/(x2-x1) I chose points (0,3) and (4,4) from graph so
m=(4-3)/(4-0)=1/4 so now the line is
y=x/4+b, using point (4,4) we can solve for b
4=4/4+b
4=1+b
b=3 so the line is
y=x/4+3 or more neatly
y=(x+12)/4

How many possible values for y are there where y= Cos -1 0
A.) 0
B.) 1
C.) infinite
D.) 2
Answer:
B) 1 possible value
FOR THIS SPECIFIC INSTANCE
Step-by-step explanation:
If it is Cos -1 (0) and cos is capitalized, that means it is a function and you apply restrictions. Based on the restrictions you get one possible value (I think the value is pi/2)
However, if the problem is cos -1(0) with no capitalization, it is a relation meaning values are infinite because of repetitions. The answers would be pi/2 and 3pi/2 and both would be added/subtracted by 2n(pi).

B
