4 goes in the blank.

In math, if any number like that is 5 or higher, it rounds to the nearest tenth.

so for example, 4 would round down to 0, and 5 would round up to 10.

So with the 4, it Makes 149.6k, which rounds down to 100,000.

Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long,
AysviL [449]

We have been given that Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long. We are asked to find the length of chain of bacteria in centimeters.

We know that 1 millimeter is equal to 0.1 centimeter.

To convert 10 milllimeters into centimeters, we will multiply 10 by 0.1.

\text{Length of bacteria in cm}=10\text{ mm}\times \frac{0.1\text{ cm}}{\text{1 mm}}

\text{Length of bacteria in cm}=10\times 0.1\text{ cm}

\text{Length of bacteria in cm}=1\text{ cm}

Therefore, the chain of the bacteria is 1 cm long.

: Cho tam giác ABC vuông tại C, trong đó AC = 0,9m, BC = 1,2m. Tính các tỉ số lượng giác của góc B, từ đó suy ra các tỉ số lượng
Xelga [282]

Answer:

Step-by-step explanation:

Vì tam giác ABC vuông tại C nên ta áp dụng định lí pitago=> AB²=AC²+BC²=0.9²+1.5²=3.06=>AB= (3 căn bậc hai của 34)/10

sin B=AC/AB=(3 căn bậc hai của 34)/34

cos B=BC/AB

tan B= AC/BC

cot B= BC/AC

Tương tự suy ra tỉ số lượng giác góc A
