Given :

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.

To Find :

How much would Mrs. Algebra's single order be.

Solution :

Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.

T = $(0.10 + 0.49 + 12.99 + 0.05)

T = $13.63

Therefore, Mrs. Algebra's single order cost is $13.63 .

Hence, this is the required solution.

Answer:

$\frac{2520}{64} {ln}^{3}$

Step-by-step explanation:

V=L×W×H

=3½in×1⅞×2¾

=3×2+1/2in × 1×8+7/8in × 2×4+3/4in

=7/2in × 15/8in × 24/4in

=2520/64 incube

so it's you tern to change into mixed fraction

sorry for that

but if it's helpful ❤❤

Answer:

The answer is 41

Step-by-step explanation:

400 = 900 + 625 - 1500 cos x

400 - 1525 = -1500 cos x

-1125 = -1500 cos

cos x = -1125/-1500

x = cos⁻¹ 0.75

x = 41.409622109

x ≈ 41°

1 find the area in square cm of a square whose side is

lara [203]

For question 1:

Part i)

2.6 x 2.6 = 6.76 cm squared

No unit conversions needed

Part ii)

1.2 dm = 1.2 / 1000000 = 0.0000012 cm

0.0000012 x 0.0000012 = 0.00000000000144 cm squared

Question 2:

16.5dm = 16.5/ 1000 = 0.0165 m

0.0165 x 0.0165 = 0.00027225 m squared

I hope this has helped

what is the slope of the line through (1,0)(1,0)left parenthesis, 1, comma, 0, right parenthesis and (3,8)(3,8)

77julia77 [94]

The slope of the line passing through (1 , 0) and (3 , 8) is 4.

Slope, commonly represented by the letter m, is a value that describes the steepness and direction of a line. The slope of a line is also called its gradient or rate of change.

It is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, $(x_{1}, y_{1} )$ and $(x_{2}, y_{2} )$ , to calculate the change in y over the change in x.
