Explanation 1:

Jennifer knows that at least one of Franklin's measures of the angles of the triangle is incorrect because the sum of the inner angles of a triangle is equal to 180°.

When you add the shown measures you get:

  • 37° + 97° + 134° =  268° ≠ 180°, which makes this an impossible triangle.

Explanation 2:

Jennifer also can know that either the measure 97° or 134° (or even both) is incorrect.

This is so because the addition of those two measures is

  • 97° + 134° = 231°

Since 231° > 180° those measures cannot be correct because the sum  of two angles of an triangle has to be less than 180°, given that when they are summed to the other angle the sum has to be 180°.

If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​
Elza [17]

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.

Monica has walked 3/2 miles in 2/3 of an hour. How many miles can Monica walk in one hour?
defon

Answer:

<u>2.25 Miles</u> is how many miles Monica can walk <u>in one hour</u>.

Step-by-step explanation:

You take 3/2 which is 1.5 in decimal form then take the 2 out of 2/3 divide 1.5 by 2, you get 0.75 then you add 0.75 to 1.5 and <u>you get 2.25 which is how many miles she walks in one hour.</u>

Bread and sugar cost 110 together,bread cost 100 more than sugar,how much does sugar cost?
dangina [55]
First write an equation system based on the problem
We can write "<span>Bread and sugar cost 110 together" as
</span>∴ b + s = 110
We can write "<span>bread cost 100 more than sugar" as
</span>∴ b = 100 + s
<span>
Second, solve the equation system by subtitution method
Subtitute b with (100+s) in the first equation, and we'll find the value of s
b + s = 110
(100 + s) + s = 110
100 + 2s = 110
2s = 110 - 100
2s = 10
  s = 10/2
  s = 5
The cost of the sugar is 5</span>

Can someone help me how to solve this?
Assoli18 [71]

Answer:

x > -5  in the answer


Step-by-step explanation:

(5 - 3x) / 4 < 5

multiplying both sides by 4:-

5 - 3x < 20

-3x < 15

x > 15/-3

x > -5  (Note the inequality sign is flipped because we are dividing by a negative number)
