Answer:

Step-by-step explanation:

The area of a triangle is

A=bh/2 where b=base dimension and h=height

1) 10(12)/2=60mm^2

2) 14(34)/2=238in^2

3) 9.5(19.25)/2=91.4375yd^2

4) 4.9(23.7)/2=232.26m^2

5) 285=15b/2, 15b=578, b=38ft

6) 17h/2=18.7, 17h=37.4, h=2.2cm

7) 12.25b/2=128.625, 12.25b=257.25, b=21in

a plane travels a distance of 6,000km in a time of 6.2 hours. What is its average speed rounded to the nearest whole number?

olga2289 [7]

Answer:

968 km/h

Step-by-step explanation:

We'll use the formula $\text{speed}=\frac{\text{distance}}{\text{time}}$

Thus

$\text{speed}=\frac{6000}{6.2}\\=967.74...\\\approx968$ (km/h) (to nearest whole number)

Misty and Yesenia have a group of Base Ten Blocks. Misty has six more blocks than Yesenia. Yesenia's blocks represent 17. Togeth

nignag [31]

Answer:

Yesenia has qty 1 of 10s and qty 7 of 1s

Misty has qty 6 of 10s and qty 8 of 1s

Step-by-step explanation:

Note that there are two different types of blocks: 1s and 10s. Let x represent the number of 10s and y represent the number of 1s.

Value of the blocks Number of blocks

Yesenia: 1x + 7y 8

Misty:

Total: 8x + 5y 22

Start with the number of blocks that Misty has: 22 - 8 = 14

Next, how many 1s can be added to Yesenia's to make 5? 15 - 7 = 8

How many blocks are left over from Misty's 14? 14 - 8 = 6

********************************************************************************************

Fill in the information:

Value of the blocks Number of blocks

Yesenia: 1x + 7y 8

Misty: 6x + 8y 14

Total: 8x + 5y 22

$1. \: 405352 \: cm = 4.05352 \times {10}^{5} \: cm$

___o___o___

2. 7.6352 x 10-3 kg ( This is scientific notation) [ If you want —> Standard notation]

7.6352 x 10^ -3 kg = 0.0076352 kg

__o_o___

$3. \: \: 3.1 \times 10 ^{4} mm + 4.87 \times {10}^{5} \: mm \\ 0.31\times 10 ^{4} mm + 4.87 \times {10}^{5} \: mm \\ = 5.18 \times {10}^{5} \: mm$

____o___o___

$4. \: \: (4.8 \times {10}^{5} \: km) \times (2.0 \times {10}^{3} \: km ) \\ = 9.6 \times {10}^{8} \: km$

____o____o____

$5.(3.3 \times{10}^{ - 4}\: ml)\div(1.1 \times {10}^{ - 6}\: ml) \\ \\ \frac{3.3 \times {10}^{ - 4} \: ml}{1.1 \times {10}^{ - 6} \: ml} = \frac{33 \times {10}^{ - 4} \: ml}{11 \times {10}^{ - 6} \: ml} \\ \\ = \frac{33 \times {10}^{ - 4 + 6} }{11} ml \\ \\ = 3 \times {10}^{2} \: ml$
