Answer:y=28
Step-by-step explanation:
all triangles add up to 180 and this triangle is an isosceles triangle so 34 should be equal to x-5 meaning that two of the angles are 34 degrees and you just need to subtract 34(2) from 180 which is 180-68 to give you 112. Then since this is the value of 4 times y, just divide 112 by four to isolate the variable and you get 28.
Carlos is using the distributive property to evaluate the expression 14 (49) by using friendlier numbers. His work is shown below. Carlos’s Work 14 (49) Step 1 14 (40 + 9) Step 2 14 (40) + 9 Step 3 560 + 9 Step 4 569 What was the first error that Carlos made?
PLZ HELP ME PLZ PLZ PLZ I NEED HELP
Answer:
The 1st error that Carlos made was in Step 2...
In step 2 , Carlos multiplied 14 only with 40. If he would have multiplied 14 with both 40 & 9 , then it could have been alright.....

Answer:
0.16
Step-by-step explanation:
We can convert 4 / 25 to 16 / 100. Since 100 ends in 2 zeroes, we know that there will be 2 digits after the decimal point, therefore, the answer is 0.16.
Answer:
0.16 is the answer
Step-by-step explanation:
just simply divide 4 by 25 and you ll get the answer

Solve the equation: 3x - x + 2 = 4(2x - 1) infinite solutions x = 1 x = -1 no solution
Answer:
[tex]x=1[/tex]
B
Step-by-step explanation:
So we have the equation:
[tex]3x-x+2=4(2x-1)[/tex]
Combine like terms on the left:
[tex]3x-x+2=4(2x-1)\\2x+2=4(2x-1)[/tex]
Distribute out the right:
[tex]2x+2=4(2x-1)\\2x+2=8x-4[/tex]
Subtract 2x from both sides. The left side cancels:
[tex](2x+2)-2x=(8x-4)-2x\\2=6x-4[/tex]
Add 4 to both sides. The right side cancels:
[tex]2+4=(6x-4)+4\\6=6x[/tex]
Divide each side by 6:
[tex](6)/6=(6x)/6\\x=1[/tex]
Therefore, the solution is: x=1.

I think this is slope. So for each point you go up 3 units. All of the point should connect into a straight line.
Step-by-step explanation:
Mark Point R on the graph to its coordniates. Do the same to Point D, L and F. after you are done then go back to each point and go up 3 units/points. Then draw a line connecting the 4 points. Then you will have your answer. Hope this helped!
What is a “real number “
Write an equation of the line below.
Answer: y = -2/5x -4
Step-by-step explanation:
First we can notice that the line is not going through the origin but is is going through the y-intercept which is -4.In this case the the equation of the line has be in slope intercept form as if y=mx +b where only m and b is indicated and m is the slope and b is the y intercept. So since we already know the y intercept is -4 we need to find the slope using the points on the line.
The points (0,-4) and ( -5,-2) lies on the line and we could use them to find the slope. To find the slope,we need to find the change in the y coordinates and divide it by the change in the x coordinates.
-4 -(-2) = -2
0 - (-5) = 5
slope: -2/5
So since the slope is -2/5 and the y intercept is -4 then we will have the equation,
y= -2/5x - 4

Answer:
[tex]B = \frac{3}{2} * 21,356[/tex]
Step-by-step explanation:
Given
Represent Jimmy with J and Bob with B
[tex]J = 21,356[/tex]
[tex]B = 1\frac{1}{2} * J[/tex]
Required
Determine the expression for B
[tex]B = 1\frac{1}{2} * J[/tex]
Substitute 21,356 for J
[tex]B = 1\frac{1}{2} * 21,356[/tex]
Convert Mixed fraction to improper
[tex]B = \frac{3}{2} * 21,356[/tex]
The above is an expression for B
Solving further, we have
[tex]B = \frac{3 * 21,356}{2}[/tex]
[tex]B = \frac{64068}{2}[/tex]
[tex]B = 32034[/tex]

Answer:
(D) C'D' and CD are equal in length
Step-by-step explanation:
When we reflect a line, nothing changes about it except it's position.
The line never gets dilated in any way.
This means that B and C must be incorrect, since they refer to dilating the line.
Now we can think about it. If we reflect a line across the y-axis, that means that the line will be parallel to the original line. This means A is false.
That leaves D.

Consider triangle GHJ. Triangle G H J is shown. Angle G H J is a right angle. The length of the hypotenuse is 10 and the length of another side is 5. What is the length of line segment HJ?
Answer:
[tex]\bold{\sqrt{75}}[/tex]
Step-by-step explanation:
Given
A [tex]\triangle GHJ[/tex] in which
[tex]\angle GHJ = 90^\circ[/tex]
Hypotenuse = 10
Length of another side = 5
To find:
HJ = ?
Solution:
Kindly refer to the image attached in the answer area.
We know that there are only 3 sides in a triangle.
We are given hypotenuse is 10.
i.e. GJ = 10
To find HJ, Base = ?
So, we are given the side length of GH, perpendicular i.e. 5.
Kindly refer to attached image for further details.
Let us use Pythagorean theorem here.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow GJ^{2} = GH^{2} + HJ^{2}\\\Rightarrow 10^2=5^2+HJ^2\\\Rightarrow HJ = \sqrt{100-25}\\\Rightarrow \bold{HJ = \sqrt{75}}[/tex]

if the product of two identical number is one thousand twenty four. Find out of the numbers
Answer:
32
Step-by-step explanation:
1,024 will be a perfect square if it is the product of 2 of the same numbers:
Calculate the square root of 1024:
[tex]\sqrt{1024}[/tex]
= 32
So, the number is 32
Answer:
32
Step-by-step explanation:
Let the unknown number be n.
When multiplied together, the product is 1,024. Therefore:
[tex]n\cdot n=1024[/tex]
Combine:
[tex]n^2=1024[/tex]
Take the square root of both side:
[tex]n=\sqrt{1024}=32[/tex]
Therefore, the unknown number is 32.

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer: fixed charge = 15, extra day = 3
Step-by-step explanation:
Let x represent the charge for an extra day (after 3 days)
Let y represent the fixed charge (for first 3 days)
Equation 1: 7 days is 4 extra days --> 4x + y = 27
Equation 2: 5 days is 2 extra days --> 2x + y = 21
Multiply the second equation by -1 and add the two equations together:
4x + y = 27
-2x - y = -21
2x = 6
x = 3
Input x = 3 into either equation to solve for y:
2x + y = 21
2(3) + y = 21
y = 15
the length and width of a rectangle is (x + 4) and x, respectively. what statement best describes (x + 4)?

A researcher at a major clinic wishes to estimate the proportion of the adult population of the United States that has sleep deprivation. How large a sample is needed in order to be 95% confident that the sample proportion will not differ from the true proportion by more than 4%?
Answer: n = 600.25 ≈ 601 ( sample size)
the minimum sample size of the adults in United State who have sleep deprivation is 601
Step-by-step explanation:
Given that;
the confidence level = 95% = 0.05
the Margin of error E = 4% = 0.04
∴ level of significance ∝ = 1 - C.L
∝ = 1 - (95/100)
= 0.05
Z∝/2 = 0.05/2 = 0.025
Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)
Now to calculate the sample size, we say
n = (Z(critical) / M.E )² P ( 1 - P)
now we substitute
n = (1.96 / 0.04)² × 0.5 ( 1 - 0.5)
n = 2401 × 0.5 × 0.5
n = 600.25 ≈ 601
Therefore the minimum sample size of the adults in United State who have sleep deprivation is 601
Using the formula for the margin of error, it is found that a sample of 601 is needed.
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
95% confidence level
So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].
In this problem:
There is no previous estimate, hence [tex]\pi = 0.5[/tex] is used.The minimum sample size is n for which M = 0.04, hence:[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.04 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]
[tex]0.04\sqrt{n} = 1.96(0.5)[/tex]
[tex]\sqrt{n} = \frac{1.96(0.5)}{0.04}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96(0.5)}{0.04}\right)^2[/tex]
[tex]n = 600.25[/tex]
Rounding up, a sample of 601 is needed.

(-2)+6(-5)+9 find the sum
Answer: We should first use order of operations to multiply 6 and -5. Then we add and subtract from left to right.
Demo:
6 * (-5) = -30
Equation looks like: -2 - 30 + 9
-2 - 30 = -32
-32 + 9 = -23
-23 is the answer to this equation.
What’s the absolute value for this ?
Answer:
The absolute value for x = 1/6
Step-by-step explanation:
Leave |x + 3| alone
2/3|x + 3| = 11/6 + 1/2 ➡ 2/3|x + 3| = 14/6
|x + 3| = 14/6 ÷ 2/3 ➡ |x + 3| = 7/2 now we write two equations
x + 3 = 7/2 or x + 3 = -7/2 first we subtract 3 from all
x = 1/6 or x = -13/6 since we are asked to find the absolute value, the answer would be 1/6
