Answers

Answer:

42°

Step-by-step explanation:

Altitude of an isosceles triangle divides it vertex in equal angles

so ∠ABD = ∠PBC = 48/2 = 24

In ΔABC sum of angles = 180 and ∠A = ∠C

48 + A + C = 180

2A = 180 - 48 = 132

A = 132/2 = 66 = ∠C

As PB = PC  ---> ∠PBC = ∠PCB = 24

∠ACB = 66 = ∠PCD + ∠PCB

66 = ∠PCD + 24

∠PCD = 42

Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?

Answers

Answer:

20%

Step-by-step explanation:

Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".

Here given that,

Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.

Number of cows Mr. Reynolds have

[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %

So, the number of cows Mr. Reynolds reduced is

[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %

Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

Answers

Answer:

Hello

Step-by-step explanation:

You can take away the decimals

for example 0.33 x 0.7

do 33 x 7

which is 231

the 0.33 has 2 decimal spaces because there are 2 digits after the point

0.7  has 1 decimal place because there is 1 digit after the point.

so in total, there is 3 decimal

because you do 2 + 1

3

from the left, you count backwards and add the decimal point

the final answer should be 0.231

S - How many positive integers are between - 7/3 and 5/2?

E. 0
F. 1
G. 2.
H. 3​

Answers

Answer:

The positive integers between -7/3 and 5/2 are 1 and 2.

Step-by-step explanation:

"How many positive integers are between - 7/3 and 5/2?" can be written as "How many positive integers are between - 2 1/3 and 2 1/2?"  This rewriting makes it easier to identify the positive integers in question.  They are 1 and 2.

The number of positive integers between -7/3 and 5/2 is 3 (option H).

To determine the number of positive integers between -7/3 and 5/2, we need to find the positive integers greater than -7/3 and less than 5/2.

Converting -7/3 to a decimal, we have:

-7/3 ≈ -2.333

Converting 5/2 to a decimal, we have:

5/2 = 2.5

Now, let's check which positive integers lie between -2.333 and 2.5.

The positive integers greater than -2.333 and less than 2.5 are 0, 1, and 2.

Therefore, there are three positive integers between -7/3 and 5/2. The correct answer is option H. 3.

Answers

Answer:

the answer would be 112.5min

Explanation:

I believe you have the equations wrong. 1 equation you can use is t=15d, and the other equation you can use is d=t/15. then if you plug 7.5 for d in one of the equations you can get the answer

Yes so well done for establishing
T= 30
And d=2
Now we need an equation that links together.
So to get d (2) equal to t (which is 30) we need to multiply by 15.
So t = 15d
Or if you make d the subject
D = 15/t

So if this Titus walks 7.5 miles
T = 15 x distance
Time = 15 x 7.5
So the time is 112.5
