Answer:

8.4

Step-by-step explanation:

Move the decimal point to create $2.8, which is 10% of $28. Once you have the 10% ($2.8) multiply it by 3 to get 30%.

Answer:

x=16 1/4

Step-by-step explanation:

is that a 11/2 or a 1 1/2? the answer i put was for 1 1/2

Answer:

x=16 1/4

Step-by-step explanation:

2 - 1/2 = 1/2

31 / 1/2 = 15 1/2

Check Answer:

(2 x 16 1/4)- 1 1/2

32 1/2 - 1 1/2

=31

Sooo:

x=16 1/4

Answer:

16

Step-by-step explanation:

If the store sells 2 printers for every 5 computers

40/5 is 8. this means there are 8 sets of 5 computers

8x2 is 16 since for every 5computers, 2 printers are sold

Answer:

f(x) = 1(x - 4)^2 - 2

Step-by-step explanation:

Recall that the vertex form of the equation of a parabola is

f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.

Looking carefully at the graph, we see that h must be 4 and k must be -2.

Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Midpoint of a line segment joining points [tex](x,y)[/tex] and [tex](u,v)[/tex] is given by [tex](\frac{x+u}{2},\frac{y+v}{2} )[/tex]

Points are R(-1,10),S(5,4)and T (-4,-2).

Midpoint of RS = [tex](\frac{-1+5}{2},\frac{10+4}{2} )=(\frac{4}{2},\frac{14}{2} )=(2,7 )[/tex]

Midpoint of RT = [tex](\frac{-1-4}{2},\frac{10-2}{2} )=(\frac{-5}{2},\frac{8}{2} )=(\frac{-5}{2},4)[/tex]

Slope of a line joining points [tex](a,b)[/tex] and [tex](c,d)[/tex] is given by [tex]\frac{d-b}{c-a}[/tex]

Slope of line joining midpoints of side RS and RT = [tex](\frac{4-7}{\frac{-5}{2}-2 })=(\frac{-3}{\frac{-9}{2} })=\frac{2}{3}[/tex]

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

[tex]2x=ky+2\to\ eq1\\(k+1)x=6y-3\to\ eq2\\$Change to this form: $y=mx+c\\ky=2x-2\\y=\frac{2x-2}{k}\\$gradient of eq1: $\frac{2}{k}\\6y=(k+1)x+3\\y=\frac{(k+1)x+3}{6}\\y=\frac{k+1}{6} x+\frac{3}{6}\\y= \frac{k+1}{6} x+\frac{1}{2}\\$gradient of eq1: $\frac{k+1}{6}\\$Since gradient, m, is the same for both lines,$\\\frac{2}{k}=\frac{k+1}{6}\\12=k^{2}+k\\k^{2}+k-12=0\\(k-3)(k+4)=0\\k=3 $ or $ k=-4[/tex]

4. The x-intercept is (10,0)

5. All of the above

Answer:

Width of the garden = 22.8 foot

Step-by-step explanation:

Area of the rectangular garden = 2077 square feet.

Let

Width of the garden = x

Length of the garden = 4x

Area of a rectangular garden = length × width

2077 = 4x * x

2077 = 4x²

x² = 2077/4

x² = 519.25

find the square root of both sides

x = √519.25

x = 22.787057730211

To the nearest tenth of a foot.

x = 22.8 foot

Width of the garden = 22.8 foot

If not try just putting hoops

from each side over the letter in the corner on the inside. Then each one will get one more than the other.

I.E. u and g get 1, f and v get 2, e and r get 3, i and s get 4, and h and t get 5.

Answer:

its B

Step-by-step explanation well you want to get ride of the zeros and substution and see which one is stronger

Answer:

A

Step-by-step explanation:

Hello there

The coefficient correlation is set on a scale of 1 to -1

1 having the strongest correlation, 5 having an ok correlation and 0 having no correlation

.193 is closest to 0 so the correlation is very weak

Remember if the coefficient correlation is positive the it will have a positive correlation and if its negative then it will have a negative correlation

So we can conclude that the answer is A

Answer:

answer is B

Answer:

69 degrees!

Step-by-step explanation:

Angle MKL = 180 - 146 = 34 (Angles on a straight line add up to 180)

Angle x = 180 - 77- 34 = 69 (Angles in a triangle add up to 180)

Hope this helps! Please mark as brainliest!

Answer:

a: 24 cm

b: 101 m

c: 1.46 mm

Step-by-step explanation:

Formula: d=2r

a: 12*2=24 cm

b: 50.5*2=101 m

c: 0.73*2=1.46 mm

Answer:

Step-by-step explanation:

yes congruent, by AAS

the angles are stating , w/ the little red lines that they are the same.. so we know two angles of the triangles are the same, and we also know that one side touching is the same.   so yes.. AAS.
