Answer:

Answer in simplified form is - 10 1/2 .

Step-by-step explanation:

We have given,

(5 1/4) ÷ (- 2 1/2)

This can be simplified as :

(5 1/4) ÷ ( -2 1/2)

Since 5 1/4 = 21/4  and -2 1/ 2 = -5/2

So we can write,

(5 1/4) ÷ ( -2 1/2) = 21/4 ÷ ( - 5/2)

or (21/4) / (-5/2)

or ( 21/4) * (-2/5)

or -42/20

or -21/10

or - 10 1/2 , this is the answer

Hence we get answer in simplified form as -10 1/2

Find the length of CA to the nearest tenth of a foot
hoa [83]

Answer:

CA ≈ 3.1 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = \frac{opposite}{adjacent} = \frac{BC}{CA} = \frac{2.6}{CA} ( multiply both sides by CA )

CA × tan40° = 2.6 ( divide both sides by tan40° )

CA = \frac{2.6}{tan40} ≈ 3.1 ft ( to the nearest tenth )

Answer these questions please: You don't need to plot the point just answer B & C. Also every single coordinate plane is lik
Nady [450]

Step-by-step explanation:

When moving left, subtract from the x-coordinate and when moving right, add in the x-coordinate. When moving down, subtract from the y-coordinate and when moving up, add in the y-coordinate.

1) Given point = (0, 0). 3 units right and 4 units down means (0+3, 0-4) = (3, -4).

2) Given point = (5, 2). 4 units left and 2 units down means (5-4, 2-2) = (1, 0).

3) Given point = (-6, -1). 8 units right and 5 units up means (-6+8, -1+5) = (2, 4).

4) In Quadrant II, the x-coordinate is negative and the y-coordinate is positive. So taking R = (-6,6). 2 units right and 6 units down means (-6+2, 6-6) = (-4, 0).

5) In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. So taking R = (6,-6). 7 units left and 4 units up means (6-7, -6+4) = (-1, -2).

The length of a rectangle is 4 more than twice the width. The perimeter is 74 feet. Find the length and width of the rectangle.
mafiozo [28]
(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26

Find the slope of the two points:<br> (5, -3) and (-9, -6)
lions [1.4K]

Slope Formula: y2-y1/x2-x1

= -6-(-3)/-9-5

=-3/-14

= 3/14

Remember, when you have 2 negative numbers in a fraction it changes it to a positive fraction.

The final slope is 3/14.

Hope This Helped! Good Luck!
