Triangle QRS is a right triangle.
What is the lenghts of RS.
0 10
0 7.1
05.3
0 14
Answer:
5.3
Step-by-step explanation:
a² + b² =² c² the Pythagorean theorem
RQ² + RS² = QS² Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28 28 is slightly > 25 and since √25 =5
RS = 5.3 actually 5.2915 to a few more significant digits
4x+2y=8
x+y=4
Elimination method & graphing method!
MUST SHOW WORK!
Answer:
x = 0 and y = 4.
Step-by-step explanation:
The given equations are :
4x+2y=8 ...(1)
x+y=4 ...(2)
Multiply equation (2) by 2.
2x+2y=8 ...(3)
Subtract equation (3) from (1).
4x+2y-(2x+2y)=8-8
4x+2y-2x-2y=0
2x = 0
x = 0
Put the value of x in equation (2).
0+y=4
y = 4
So, the value of x and y are 0 and 4.
Use y = 5x + 36 to find the value of x when y = 80.
Answer:
If y = 80 then 5x+36 also equals 80
80 - 36 = 44
therefore 5x = 44
44 / 5 = 8.8
x=8.8

Answer:
(4,0)
Step-by-step explanation:
(5,3) (1,3)
You need to subtract from the x axis on both coordinates and the y axis in both coordinates.

(4,0)
I also checked on a graph as well, so it's correct.
Trigonometric Ratios
Find h.
Answer:
63
Step-by-step explanation:
use tangent formula
[tex] \tan(40) = \frac{h}{75} [/tex]
Answer:
h ≈ 62.9 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )
75 × tan40° = h , then
h ≈ 62.9 ft ( to 1 dec. place )
Which weighs more: a puppy that weighs 8.5 kilograms or a baby that weighs 11 pounds? Explain your reasoning.
Answer:
a baby weight more because the baby will grow and will weight more then a puppy
Step-by-step explanation:
Answer:
A puppy that weights 8.5 kilograms weighs more.
Step-by-step explanation:
A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.
Puppy's Weight Kilograms: 8.5
Puppy's Weight Pounds 18.7
Baby's Weight Kilograms: 5
Baby's Weight Pounds: 11
Weight in Kilograms: Puppy: 8.5 > Baby: 5
Weight in Pounds: Puppy: 18.7 > Baby: 11
Therefore, the puppy is heavier.

Daniel had a social studies quiz. He answered eighty-seven out of 100 exercises correctly. Choose the decimal that shows the part of the quiz that Daniel answered correctly.
Answer:
0.87
Step-by-step explanation:
Out of a total number of 100 questions, Daniel is said to have answered 87.
We first express this as a fraction.
Total number of questions he answered divided by total number of quiz questions
= 87/100
As a decimal, 87 divided by 100 = 0.87.
You can easily get this by using the calculator.
Thank you!
Answer:
Step-by-step explanation:
0.87 because 87+0=87

a string of length is cut into 2pieces in the ratio 3:5 find the length of each piece
Answer:
Let the length of shorter piece be 3x and length of longer piece be 5x (THEIR RATIO IS 3:5)
Now, length of longer piece is 20 cm
So,
5x=20
x=4
Hence, length of shorter piece = 3x = 3*4=12 cm
Step-by-step explanation:
not sure, correct if im wrong
Answer:12.5cm
Step-by-step explanation:
Divide 240 g in the ratio 5: 3:4
Answer:
Total weight=240g
Ratio=5:3:4
5x+3x+4x=240
12x=240
x=20
5x=100
3x=60
4x=80
Therefore 100g:60g:80g

400 = (L+30) X w
400 = 10+30 x 10 ( just b/c I can see 40 x 10 would be 400, calculus could also figure this out for us, but... that would be the minimum fencing he needs to buy and this questions isn't asking that, just make it fit on the back of his house, which we are not given, so just make up something, I used 10 b/c it was convenient )
400 = 40 x 10
2 sides are 40 , and one side is 10
so 90' of fence is needed
Let R be the region enclosed by the y-axis, the line y=1 and the curve y=x^3. A solid is generated by rotating R about the line y=1. What is the volume of the solid
Answer:
The volume of the solid is 19.[tex]\overline{142857}[/tex] unit³
Step-by-step explanation:
The given function is y = x³
The solid is created by revolving R about the line y = 1
We have that when y = 1, x = 1
Taking the end point as x = 2, we have the volume given by the washer method as follows;
[tex]V = \pi \cdot \int\limits^a_b {\left( [f(x)]^2 - [g(x)]^2 \right)} \, dx[/tex]
Where;
a = 1, and b = 2, we have;
g(x) = 1
[tex]V = \pi \cdot \int\limits^{2}_1 {\left( [x^3]^2 - [1]^2 \right)} \, dx = \pi \cdot \left[\dfrac{x^7}{7} + x \right]_1^{2} = \pi \cdot \left[\dfrac{2^7}{7} +2 -\left( \dfrac{1^7}{7} + 1\right)\right] =19\dfrac{1}{7}[/tex]
The volume of the solid, V = [tex]19\dfrac{1}{7}[/tex] unit³ = 19.[tex]\overline{142857}[/tex] unit³
Simplify (6²)(3-8)(3-6)4

GEOMETRY:
Explain why segment PR is congruent to segment VE, given segment VO is congruent to segment RO and line PR is parallel to line VE
Answer:
See explanation
Step-by-step explanation:
∠POR is congruent to ∠VOE because they are vertical angles
∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.
VO is congruent to OR which is given
Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem
So, PR is congruent to VE because corresponding parts of congruent triangles are congruent
Use prime factorization to find the LCM and the HCF of 210 and 112
Answer:
HCF = 14
LCM = 1680
Step-by-step explanation:
Factorizing the given values
210 = 2 * 3 * 5 * 7
112 = 2 * 2 * 2 * 2 * 7
Since 2 * 7 is common to both factors
Hence the HCF = 2 * 7 = 14
For LCM, we we will multiply all the prime factors that are in both
LCM = 2* 2 * 2 * 2 * 3 * 5 * 7
LCM = 112 * 15
LCM = 1680
Hence the LCM is 1680

a. What is 25% of 160?
Answer:
40
Step-by-step explanation:
Hi there,
Before solving this problem, it is useful to know that 25% is equivalent to 1/4 or 0.25. There are two ways to solve this problem:
1.) Multiply 0.25 by 160
or
2.) Divide 160 by 4.
Either way, the answer is still 40. Hope this answer was useful. Cheers.
