is 8 a solution to 1/2x+9=13?

The answer is 25

Combind like terms the 3z+z which equals 4z then  subtract 25 from both sides.  Meaning 25-25 and 125-25. After you minus you get 100. The set up should look like this: 4z=100 then you divide it by 4z on both sides your answer should be z=25.

Hope this helps!

Answer:

x = 9°

y = 39°

Step-by-step explanation:

7x = 63

x = 9°

3y + 63 = 180

3y = 117

y = 39°

Answer:

39

Answer:

The selected answer is correct (8 cm)

Step-by-step explanation:

So in this problem

we are given that the total length of the composite figure is 14 cm (this including the rectangle's length and the triangle's base length)

We also happen to be given the rectangles length

So we can find the triangles base length by subtracting the total length of the figure by the length of the rectangle

Triangle base length = 14 cm - 6 cm

14 - 6 = 8

Hence the answer is 8 cm

Answer:

The juice concentration in the punch that Johan added was 35%.

Step-by-step explanation:

Since a bottle contains 750mL of fruit punch with a concentration of 50% pure fruit juice, and Johan drinks 100mL of the punch and then refills the bottle with an equal amount of a cheaper brand of punch, if the concentration of juice in the bottle is now reduced to 48%, to determine what was the concentration in the punch that Johan added, the following calculation must be performed:

750 = 100

650 = X

650 x 100/750 = X

65000/750 = X

86,666 = X

86.666 x 0.5 + 13.333 x 0.4 = 0.486662

86.666 x 0.5 + 13.333 x 0.39 = 0.4853287

86.666 x 0.5 + 13.333 x 0.35 = 0.4799955

Thus, the juice concentration in the punch that Johan added was 35%.

Answer:

64.8 ft

Step-by-step explanation:

A square has all its sides equal

Therefore to get one side from its area is simply finding the square root of its area

√262.44=16.2ft

Having the one side then perimeter= to the four equal sides × the dimensions of one side

=4×16.2

=64.8 ft

Answer:

51.2

Step-by-step explanation:

Since it's a percentage all you have to do is multiply 32 by 1.6 because a 100 percent is equivalent to 1 so 160 percent is equivalent to 1.6.

Answer:

250000

Step-by-step explanation:

P=986.50(1-(1+.0249/12)^-(12)(30) Then divide the answer you get by (.0249/12)

Answer: 250,000

Step-by-step explanation:

We must apply the formula for P0, that is,

P0=986.50(1−(1+0.024912)−30⋅12)(0.024912),

which gives P0=$250,000 to the nearest $1.

Answer:

  (x +6)^2 +(y -10)^2 = 225

Step-by-step explanation:

The standard form equation for a circle is ...

  (x -h)^2 + (y -k)^2 = r^2

where the center is (h, k) and the radius is r.

The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.

  ((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)

The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.

  (x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2

  (x +6)^2 +(y -10)^2 = 81 +144 = 225

The equation of the circle is ...

  (x +6)^2 +(y -10)^2 = 225

Answer: NO

Step-by-step explanation:

Answer:

A. $0.89

Step-by-step explanation:

To find the constant of proportionality, find the cost of one pound of potatoes

3.56/4

= 0.89

So, the constant of proportionality is $0.89

The correct answer is A. $0.89

Using angle sum property

[tex]\\ \sf\longmapsto x+43+73+70=180[/tex]

[tex]\\ \sf\longmapsto x+43+143=180[/tex]

[tex]\\ \sf\longmapsto x+186=180[/tex]

[tex]\\ \sf\longmapsto x=180-186[/tex]

[tex]\\ \sf\longmapsto x=-6[/tex]

Option C is correct

Sum of angles of any triangle is 180°

Option C

Answer:

[tex]X=17.9m[/tex]

Step-by-step explanation:

Length of arc [tex]L_a=24m[/tex]

Height of arc [tex]H_a=8m[/tex]

Tet the length on the ground be

[tex]2a=24\\ a=12m[/tex]

Generally the Pythagoras equation is mathematically given by

[tex]a^2=b^2+c^2[/tex]

[tex]c^2=a^2+b^2[/tex]

[tex]c^2=12^2+8^2[/tex]

[tex]c^2=144^2+64^2[/tex]

[tex]c=8.9[/tex]

Therefore the distance between he person throwing the ball and the point on the ground at which the ball first strikes X

[tex]X=2c\\X=2*8.9[/tex]

[tex]X=17.9m[/tex]
