elena-14-01-66 [18.8K]

Answer:

31:21

Step-by-step explanation:

3/5 = 0.6. multiply both number by 0.6 to get 24 and 7.2 now you cannot have part of a win or a loss that makes no sense. so round it and you get 24 and 7 add those together to get 31. subtract 31 from 52 to get 21. he had 31 wins and 21 losses.

Classify the following triangle. Check all that apply.

V125BC [204]

Acute < 90
Right = 90
Obtuse > 90
This triangle is 104 degree so it is obtuse.

Isosceles = 2 same size
Scalene = no same size
Equilateral = all same size
You can see their is mark on 2 sides so it would be isosceles

What is the decimal multiplier to increase by 1.5 pls do the step by step explanation ineed help

satela [25.4K]

Answer:

Just an explanation so you can understand

Step-by-step explanation:

To increase, or decrease a number N, by a percentage X% we multiply N by a percentage multiplier (often just called multiplier).

We can calculate any percentage increase, or decrease, in three steps:

Step 1: write X% in decimal form. Remember, this is done by moving the number X back two decimal places.

Example: 5%=0.05, 12%=0.12, ... .

Step 2: Calculate the percentage multiplier by adding, or subtracting, the decimal found in step 1 to, or from, 1

For percentage increases: add the decimal to 1.

For percentage decreases: subtract the decimal from 1.

Step 3: multiply the number N by the multiplier, found in Step 2.

A right triangle has one angle that measures 59º. What is the measure of the other<br> acute angle?

photoshop1234 [79]

Answer: 31°

Step-by-step explanation:

We know that a right triangle is equal to 180°. Since this is a right triangle, we know that one angle is 90°. Since we are given out other angle, it is very easy to find the missing angle.

180°=59°+90°+x

180°=149°+x

x=31°

The number of hours, t, that bacteria spread 10-fold can be modeled by the equation B(t) = B0(10)2t. There are 25 bacteria prese

nordsb [41]

Answer: 1.67 hours.

Explanation:

1) Function that models the number of bacteria:

$B(t)=B_0(10)^{2t}$

2) Bo = 25, then the function is:

$B_0=25(10)^{2t}$

3) To know how many hours will elpase until the number of bactaria is 55,00, you equals B to 55,500 in the equation and solve for t, in this way:

i) start

$55000=25(10)^{2t)$

ii) division property

$2200=10^{2t}$

iii) antilogarithm property

$2t = log_{10}2200$

iv) division property

$t=\frac{log_{10}2200}{2}$

v) Due the operations:

t = 1.67 hours.

Note that the time is less than 2 hours. That sounds fine since after 1 hour there will be 10 times 25 (250 bacteria), and after 2 hours 100 times 25 (2500 bacteria).
