Name two obtuse angles

Construyendo y resolviendo una ecuación, tenemos que el número puede ser 8 o -10.

Para encontrar el número, tenemos que resolver una ecuación cuadrática, luego:

[tex]x^2 + 2x - 5 = 75[/tex]

[tex]x^2 + 2x - 80 = 0[/tex]

Ecuación cuadrática con [tex]a = 1, b = 2, c = -80[/tex]

[tex]\Delta = 2^2 - 4(1)(-80)[/tex]

[tex]x_{1} = \frac{-2 + \sqrt{324}}{2} = 8[/tex]

[tex]x_{2} = \frac{-2 - \sqrt{324}}{2} = -10[/tex]

El número puede ser 8 o -10.

Answer:

0.8

Step-by-step explanation:

Answer:

[tex] \longmapsto (4 \times {10}^{ - 1} ) + (4 \times {10}^{ - 1} ) \\ = \frac{4}{10} + \frac{4}{10} \\ = \frac{(4 + 4)}{10} \\ = \frac{8}{10} \\ = \boxed{8 \times {10}^{ - 1} }[/tex]

Answer:

1) [tex](3.5)^{2} ; \frac{57}{5}; 6\sqrt{3}; 9.8; \sqrt{75}[/tex]

2) I found their alternate forms. So in the order the #'s were given its 10.4;12.3;8.7;9.8;11.4

3)[tex]x\sqrt{75};9.8x;6x\sqrt{3};\frac{57x}{5}; x(3.5)^{2}[/tex]

4) I chose a negative number to base my calculations off (-2) then found their alternate from's. In order they were given its -20.8; -24.5; -17; -19.6; -22.8

2.c

3.a

Step-by-step explanation:

1. because angle 4 and angle 8 are in the  same spot

2. these are alternative interior angles on a parell line so the are congruent

3. angle 2 and angle 5 are on the same side and inside the 2 lines

Yes me I comment first yay!!

Answer:

18x^2 - 17x +9

Step-by-step explanation:

Original equations:

10x^2 - 10x + 2

-8x^2 +7x - 7

Calculations:

10x^2 - (-8x^2) = 18x^2

(-10x) - 7x = -17x

2 - (-7) = 9

Together, they make: 18x^2 - 17x + 9

Answer:

3/4 = A

Step-by-step explanation:

-8+Ax(-8) - (-6)= -8 - 8A + 6

-3 + (-8)/2x4 = -3 -1= -4

---------------------------------------

-8 -8A + 6= -2(-4)

-8 + 8 +6=8A

6/8=A

3/4 = A

Answer:

for the first on it says x + 20 - 1

and if x=9

then you just plug it in

so you would get

9 + 20 -1

then you solve

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]\cfrac{7}{9}\:x-\cfrac{4}{9}\:x=\cfrac{1}{4}+\cfrac{5}{12}[/tex]

First, combine  [tex]\frac{7}{9} x[/tex] and [tex]-\frac{4}{9} x[/tex] =  [tex]\frac{1}{3} x[/tex]

[tex]\cfrac{1}{3}\: x=\cfrac{1}{4} +\cfrac{5}{12}[/tex]

LCM of 4 and 12 is 12, Convert 1/4 and 5/12 to fraction with denominator 12:

[tex]\cfrac{1}{3}\: x=\cfrac{3}{12} +\cfrac{5}{12}[/tex]

Since 3/12 and 5/12 have the same denominator, let's add numerators:

[tex]\cfrac{1}{3}\:x=\cfrac{3+5}{12}[/tex]

[tex]\cfrac{1}{3}\:x=\cfrac{8}{12}[/tex]

Reduce the fraction 8/12 to lowest term by extracting and  canceling out 4,

[tex]\cfrac{1}{3} \:x=\cfrac{2}{3}[/tex]

Multiply both sides by 3, reciprocal of 1/3:

[tex]x=\cfrac{2}{3} \times 3[/tex]

Cancel out 3 and 3:

[tex]x=2[/tex]

Answer:

D

Step-by-step explanation:

The vertex of the triangle is adjacent to 90° on a straight line, so

vertex = 180° - 90° = 90°

The triangle has 2 congruent sides and is therefore isosceles with 2 congruent base angles, then

x = [tex]\frac{180-90}{2}[/tex] = [tex]\frac{90}{2}[/tex] = 45° → D

Answer:

24) 10:50

25) 1,2,5,10,50,25

26) 3 inches

27) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total

28) B

29) 1/6

30) 21 degrees was the high temperature

Step-by-step explanation:

- I can't see the clock well, but I'll guess its 10:20. 30 minutes after would be 10:50.

- There are 6 common factors of 50 and 100.

1,2,5,10,50,25

- 12/4 is 3.

- A shopper purchased 2 items, each were $3.49 (That is all the info we need to create an equation to solve/estimate the cost of the purchase) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total

- We multiply 1/3 by x amount of batches. So in this case we have 2. It becomes 1/3 times 2 = 1/6

- The low temperature is 8 degrees because each line represents a difference of 2 and 10 - 2 = 8. Now to calculate the high temperature, you add 13 to 8 = 21.

Answer:

What can I do for you

Step-by-step explanation:

Answer:

a) 115°

Step-by-step explanation:

first find the value of angles B and C by doing 180 - 50 =130 and then 130÷2 because B and C are equal

Since the lines BO and CO are bisectors, it means that the angles are halved fo take half of angle B plus half of angle C and add them together = 65 and then do 180-65=115 so the angle BOC is 115°

Answer: ±11

Answer:

q(8) = 39.

Step-by-step explanation:

relate the values

for,

q(x) = 1/2x² + 7

q(8) = 1/2(8²) + 7

q(8) = 39.

Answer:

q(8) = 39

Step-by-step explanation:

To solve this question, you need to plug in (substitute) 8 instead of x:

q(8) = [1/2(8)²] + 7

= (1/2 × 64) + 7

= 32 + 7

= 39

∴ q(8) = 39
