What is x and y if -4x+y=11
Answer:
See the expression below
Step-by-step explanation:
Given data
We have the expression
-4x+y=11-----------1
from 1 make y subject of formula we have
y=100+4x
Make x subject of the formula we have
-4x=11-y
divide both sides by -4
x=(11-y)/-4

Answer: 1/8
Step-by-step explanation: The sample space are all of the different outcomes an event can lead to. The H and T combinations at the bottom are all of the different outcomes. I think the probability of getting 3 tails for the coins (or TTT) is 1/8. This is because there are 24 total outcomes (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). There is 3/24 TTTs (also, 1/8 if you count the groups/simplify). Therefore, it is 1/8. Hope this helps!
If 8 bottles of cold drink is Rs.480. Then find a) What will be the cost of 5 bottles of cold drink? B) How many bottles of cold drink can be purchased for Rs.640.
Answer:
(A) 300
(B) 11
Step-by-step explanation:
8 bottles of drink cost 480
Therefore one bottle will cost
= 480/8
= 60
(A) 5 bottles of cold drink will cost
= 60×5
= Rs300
(B) The bottles of drink that can be purchaseed at Rs640
= 640/60
= 11 bottles

Zoey inflated 24 balloons for the high school dance. If Zoey inflated 15% of the total number of balloons at the dance, how many balloons are there total?
Answer:
Total number of balloons= 160
Step-by-step explanation:
Giving the following information:
Number of balloons inflated by Zoey= 24
Proportion of balloons inflated= 15%
To calculate the total number of balloons, we need to use the following formula:
Total number of balloons = Number of balloons inflated by Zoey / Proportion of ballons inflated
Total number of balloons= 24 / 0.15
Total number of balloons= 160

Can someone pls explain Pythagorean Theorem to me
Thank you
Answer:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
Answer: In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

Two friends leave school at the same time, Sarah is heading due north and Beth is heading due east. One hour later they are
5 miles apart. If Sarah had traveled 4 miles from the school, how many miles had Beth traveled?
OA. 2 miles
ОВ.
1 mile
OC. 3 miles
Answer:
Step-by-step explanation:
If you picture this scene in your head, you will get a simple 3x4x5 right triangle. 4 times 2 is 8, 5 times 2 is 10, so Sarah should, by now, have traveled 3 times 2 miles.
Final answer: Sarah has traveled 6 miles after an hour.
Hope this helped! :)
Helping tip: The reason it is not 4 is because they are not traveling west and east away from each other. They are traveling north and east, so they are moving in two directions to form a right triangle, and the hypotenuse would be 10 (miles). The side, or distance, that Beth has traveled is 8. So as this is a typical variation of a 3x4x5 triangle, Sarah will have traveled 6 miles.

Which item in nature does NOT follow the Fibonacci Sequence *
Pinecone
Artichoke
Nautilus Shell
Pineapple
Answer:
all follow the sequence
Step-by-step explanation:
Pinecone and Pineapple - Scales and bracts are modified leaves, and the spiral arrangements in pine cones and pineapples reflect the spiral growth habit of stems. To confirm this, bring in a leafless stem from some tree or shrub and look at its buds, where leaves were attached.
Artichoke - The spiral of an artichokes leaves can be described by the Fibonacci Sequence. This sequence is a simple mathematical pattern where each successive number in the sequence is equal to the sum of the two preceding numbers, beginning with 0 and 1.
Nautilus shell - Each number is the sum of the two previous numbers. An approximation of a logarithmic spiral, created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.

Brianna has $37 in her checking account. She deposits $150. Then she writes a check for $61. How many dollars does she have in her checking account now?
Answer:
$126
Step-by-step explanation:
A deposit adds money into your checking account, so add $150 to $37.
150+37=187
If you write a check, you take money out, so subtract $61 from $187
187-61=126
Your final answer is $126. Hope this helps!

what is the measure of C?
Answer:
10.82 or [tex] \sqrt{117} [/tex]
Step-by-step explanation:
pythagorean theorem is x^2+y^2=r^2
9^2+6^2=r^2
117=r^2
r= [tex] \sqrt{117} [/tex]
Answer:
10.81665383 about 10.8 units
Step-by-step explanation:
how to find the hypotenuse is a^2 + b^2 = c^2
a = 9
b = 6
9^2 + 6^2
9 x 9 = 81
6 x 6 = 36
81 + 36 = 117
177 = c^2
find the square root of 177 = 10.81665383 about 10.8
A right triangle has side lengths a, b, and c as shown below.
Use these lengths to find tanx, cosx, and sin x.
Step-by-step explanation:
step 1. tan x = opposite/adjacent = c/b
step 2. cos x = adjacent/hypotenuse = b/a
step 3. sin x = opposite/hypotenuse = c/a
Graph: y = (x+3)²- 4

On Monday, a museum had 350 visitors. On Tuesday, it had 680 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change between Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that On Monday, a museum had 350 visitors while on Tuesday, it had 680 visitors. The percent change in the number of visitors to the museum will then be:
= (680 - 350)/350 × 100
= 330/350 × 100
= 94.29%
The number of people that'll have to visit on Wednesday to have the same estimated percent change will be:
= 680 + (94.29% × 680)
= 680 + (0.9429 × 680)
= 680 + 641
= 1321
