Answer:
17
Step-by-step explanation:
This is an isosceles triangle. However, it doesn't really matter since ALL TRIANGLES HAVE A SUM OF 180 DEGREES.
Now that you know that, you can add up all of the angles and set it equal to 180.
[tex](x+17) + (6x+10) + (4x-34)=180[/tex]
Now solve for x
[tex](x+17) + (6x+10) + (4x-34)=180\\11x-7=180\\11x=187\\x=17[/tex]
The value of x is 17.
A verandah is 40 m long and 15 m broad. It is to be paved with stones, each measuring 6
dm by 5 dm. Find the number of stones required.
Please help me out!!!!!!
Answer:
200 stones.
Step-by-step explanation:
Given that the verandah is 40 meters long by 15 meters wide, and that it is going to be paved with stones that measure 6 decimeters by 5 decimeters, to determine the amount of stones that should be used, the following calculation must be performed:
1 m = 10 dm
Verandah's surface: 40 x 15 = 600m2
Stones' surface: 6 x 5 = 30dm2 = 3m2
600/3 = X
200 = X
Therefore, 200 stones should be used to pave the entire verandah.

A sum of money is shared among Jen, Mary and Lilly in the ratio of 2:3:5. If Mary gives $27 to Jen, then both of them will have an equal amount of money. How much money does Lilly have?
[tex]3x-27=2x+27[/tex]
Given:
Sum of money is shared among Jen, Mary and Lilly in the ratio of 2:3:5.
If Mary gives $27 to Jen, then both of them will have an equal amount of money.
To find:
The money Lilly have.
Solution:
Let Jen, Mary and Lilly have money 2x, 3x and 5x respectively.
Mary gives $27 to Jen, then both of them will have an equal amount of money. It means,
[tex]3x-27=2x+27[/tex]
Isolate variable terms.
[tex]3x-2x=27+27[/tex]
[tex]x=54[/tex]
Now, the money Lilly have is
[tex]5x=5\times 54[/tex]
[tex]5x=270[/tex]
Therefore, Lilly have $270.

Answer:
When y = 0, x = -14
Thus, the x-intercept of the line is:
(x, y) = (-14, 0)
Step-by-step explanation:
From the table, taking two points
(-94, 24)
(-74, 18)
Finding the slope between (-94, 24) and (-74, 18)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-94,\:24\right),\:\left(x_2,\:y_2\right)=\left(-74,\:18\right)[/tex]
[tex]m=\frac{18-24}{-74-\left(-94\right)}[/tex]
[tex]m=-\frac{3}{10}[/tex]
We know the slope-intercept form of line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -3/10 and the point (-94, 24) in the slope-intercept to determine the y-intercept 'b'
[tex]24\:=\:-\frac{3}{10}\left(-94\right)+b[/tex]
[tex]\frac{3}{10}\cdot \:94+b=24[/tex]
[tex]\frac{141}{5}+b=24[/tex]
[tex]b=-\frac{21}{5}[/tex]
now
substituting m = -3/10 and y-intercept 'b=-21/5' in the slope-intercept of line equation
[tex]y = mx+b[/tex]
Thus, the equation of the line will be:
[tex]\:y\:=\:-\frac{3}{10}x-\frac{21}{5}[/tex]
We know that the x-intercept can be determined by setting y = 0, and determining for x. so,
[tex]\:0\:=\:-\frac{3}{10}x-\frac{21}{5}[/tex]
switch sides
[tex]-\frac{3}{10}x-\frac{21}{5}=0[/tex]
[tex]-\frac{3}{10}x=\frac{21}{5}[/tex]
[tex]-3x=42[/tex]
divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{42}{-3}[/tex]
[tex]x=-14[/tex]
so when y = 0, x = -14
Thus, the x-intercept of the line is:
(x, y) = (-14, 0)
y= -2(x-9)(x+7) can you put this into standard form
Answer:
y= -2x^2+4x+126
Step-by-step explanation:
A random sample of 28 items is drawn from a population whose standard deviation is unknown. The sample mean is x=900 and the sample deviation is s = 10. Use appendix D to find the values of student's t. (a) Construct an interval estimate of u with 98% confidence. (Round your answers to 3 decimal places.)
Answer:
795.596≤u≤804.403
Step-by-step explanation:
Confidence interval is expressed using the formula;
CI = xbar ± (z*s/√n)
xbar is the sample mean
z is the z score at 98% confidence
s is the standard deviation
n is the sample size
Given
xbar = 800
z = 2.33
s = 10
n = 28
Substitute into the formula;
CI =800 ± (2.33*10/√28)
CI = 800 ± (2.33*10/5.2915)
Ci = 800± (2.33* 1.8898)
CI = 800 ± 4.4033
CI = (800-4.4033, 800 + 4.4033)
CI = (795.596, 804.403)
Hence an interval estimate of u with 98% confidence is expressed as
795.596≤u≤804.403

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play. Each pair of
wings is made with 3/4 yard of fabric. The fabric costs $8 perlyard. You'll apply properties of
Multiplication in the following steps to find the total cost of fabric
Question: Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of
wings.
Answer:
3/4 * 13 = 9.75
Step-by-step explanation:
if you need to make 13 pairs of wings and don't know how much fabric you need, you need to multiply 13 and 3/4 together to get the answer you want.
3/4 * 13 = ?
3/4 [divide 3 by 4] = 0.75
so 0.75 * 13 = 9.75
so you need 9.75 yards of fabric to create 13 pairs of wings.
as a fraction it would be I think -> 39/4

Proportional, y = 3 times xNot proportionalStep-by-step explanation:
The graph shows a proportional relationship if it is a straight line that goes through the origin (0, 0). The constant of proportionality can be found by looking for the y-value when x = 1.
1) The graph is a straight line that goes through the origin. The relationship is proportional. When x=1, y=3, so ...
y = 3 times x
__
2) The graph does not go through the origin. The relationship is Not Proportional.
Edward deposited $7,500 into a savings account 2 years ago. The simple interest rate is 2%. How much money did Edward earn in interest? What would be his new account balance?
Answer:
The interest is $300 and the amount is $7800
Step-by-step explanation:
Given
P = $7,500
i = 2% = 0.02
t = 2 years
Using the formula
I = P × i × t
I = 7,500 × 0.02 × 2
I = $300
Thus, Edward earned an interest = $300
The amount in his new account bank can be calculated using the formula:
A = P + I
Since P = $7,500 and I = $300
A = P + I
= 7,500 + 300
= $7800
Thus, the new amount in his bank account = A = $7800
Therefore,
The interest is $300 and the amount is $78006. What is the volume of the cylinder? ( TI = 3.14).

EF?
9514 1404 393
Answer:
EF = 5
Step-by-step explanation:
Given:
EF = 6x -31
BD = 64 -9x
BD = 2·EF
Find:
EF
Solution:
BD = 2·EF
64 -9x = 2(6x -31) . . . . substitute the given expressions
64 -9x = 12x -62 . . . . eliminate parentheses
126 = 21x . . . . . . . . . . . add 62+9x
x = 6 . . . . . . . . . . . . . . . divide by 21
Now the length of EF is ...
EF = 6x -31 = 6(6) -31
EF = 5
