Answer:
7.0
Step-by-step explanation:
Right angled triangle. To find the hypotenuse, use Pythagorean theorem.
Hypotenuse² = base² + altitude²
= 6.5² + 2.7²
= 42.25 + 7.29
= 49.54
hypotenuse = √49.54 = 7.04 = 7
Step-by-step explanation:
by using Pythagoras law
h²=p²+b²
missing angle =h let
h²=(2.7)²+(6.5)²
h=√(49.50)=7.03=7

A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answers
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.
The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacteria be 400,000. Let x represent the number of days and f(x) represent the amount of bacteria. Write an equation.
Answers
Answer:
f(x) = 50000*2^x3 daysStep-by-step explanation:
Given:
Initial amount of bacteria = 50000Growth rate = 2 times a dayRequired equation:
f(x) = 50000*2^xSolve for x:
400000 = 50000*2^x2^x = 400000/500002^x = 82^x = 2^3x = 3After 3 days bacteria numbers will reach 400000

5-divide 180 kd between ahmed ,jasim and Dalal in the ratio of 3:1:5.
answer any one of this questions
Answers
Answer:
1) Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) I disagree
3) 7.88
4) 2.32
5) Ahmed = 60 kg
Jasim = 20 kg
Dalal = 100 kg
Step-by-step explanation:
1) diameter = 24 cm was rounded up to the nearest cm.
Now, usually, we round up 0.5 to the next whole number. This means that, the actual diameter is;
23.5 ≤ D < 24.5
Thus;
Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) If you weigh 57g,converting to kg is 0.57 kg.
Now, this does not fall in between 56.5kg and 57.5kg given.
Thus, I disagree that your weight could be anything between 56.5kg and 57.5kg .
3) 7.875 approximated to the nearest two decimal place = 7.88
4) 2.3242900000 to the nearest 2 decimal place = 2.32
5) 180 kd shared between ahmed ,jasim and Dalal in the ratio of 3:1:5.
Total part of ratio = 3 + 1 + 5 = 9
Their respective shares are;
Ahmed = 3/9 × 180 = 60 kg
Jasim = 1/9 × 180 = 20 kg
Dalal = 5/9 × 180 = 100 kg

d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3

Which value is a solution to the inequality x 4
Answers
Answer:
The answer is D
Step-by-step explanation:
We want to see which of the given values is a solution of the inequality:
x < 4
The correct option is A, x = 3.
Finding the solution:
So the inequality:
x < 4
This means that the variable must be a number smaller than 4.
Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3
Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
Answers
Answer:
The percent change is -7%.
Step-by-step explanation:
In order to find the answer, you can use the following formula:
Percent change=(New value-Old value/Old value)*100
New value=71-5=66
Old value=71
Now, you can replace the values on the formula:
Percent change=(66-71/71)*100
Percent change=(-5/71)*100
Percent change=-0.07*100
Percent change=-7%
According to this, the answer is that the percent change is -7%.
The quadrilateral below is a rectangle. Solve for x and m
Answers
Answer:
x = 13
∠WZX = 57°
Step-by-step explanation:
Because it is a rectangle, ∠XYZ is 90°
∠XZY + ∠YXZ = 90
(5x - 8) + (x + 20) = 90
simplify:
6x + 12 = 90
subtract 12 from each side
6x = 78
divide both sides by 6
x = 13
∠WZX is complimentary to angle (x + 20)
∠WZX = 90 - (13 + 20) = 57°

Answers
Answer:
x = -5
y = -1
Step-by-step explanation:
Y= -6/5x-7 and y=2/5x+1
then:
-6/5x - 7 = 2/5x + 1
simplify:
-8/5x = 8
divide both sides by 8:
-1/5x = 1
multiply both sides by 5:
-x = 5
x = -5
y = 2/5(-5) + 1 = -2 + 1 = -1

Answer:

Step-by-step explanation:
I saw karma so i came as fast as I could- welp anyways
Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).
Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.
30-18=12, yep
now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.
3(0)-2(-6)=12
0+12=12, yep
So I definitely works
For II, lets do the same thing
(10, 9) -- 9=3/2*10-6
9=15-6, works
(0, -6) — -6= 3/2*0-6
-6=0-6, also works
So uh therefore I and II both work you see what I mean-
i apologize in advance if i made you more confused than you already are-
Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest that he paid was $160 how much money did he borrow
Answers
Given:
Rate of simple interest = 5%
Time = 4 years
Total interest = $160
To find:
The amount borrowed by Austin from a credit union.
Solution:
The formula for simple interest is:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting [tex]I=160,r=5,t=4[/tex] in the above formula, we get
[tex]160=\dfrac{P\times 5\times 4}{100}[/tex]
[tex]160=\dfrac{20P}{100}[/tex]
[tex]160=\dfrac{P}{5}[/tex]
Multiply both sides by 5.
[tex]800=P[/tex]
Therefore, Austin borrowed $800 from a credit union for 4 years.
