Answer:
Step-by-step explanation:
Since the altitude of an isosceles triangle drawn from its vertex angle bisects the base, we can use the pythagorean theorem to say that:
16^2 = x^2 + x^2
256 = 2x^2
128=x^2
x = 8sqrt2.
so the base has a length of 16sqrt2.

Mrs. Ming invested an amount of money in two accounts for one year. She invested some at 8% interest and the rest at 6% interest. Her total amount invested was $1,500. At the end of the year, she had earned $106. 40 in interest. How much had Mrs. Ming invested in the account paying 6%? $117 $680 $760 $820.
Interest rate for one year is rate percent amount of original investment. The amount invested by Mrs. Ming in the account paying 6% was $680
How to calculate interest after 1 year if the rate of interest is R% annually?Suppose that annually there is interest rate of R%. The amount initially invested is P, then for 1 year, it doesn't matter if its simple or compounding annually, the interest is same (it doesn't remain same if compounding isn't annually or if the time is > 1 year)
The interest for 1 year will be [tex]\dfrac{P}{100} \times R[/tex]
Let we have the initial amount spent in account paying 8% interest rate as $x
Let for 6% interest paying account, initial amount was $y
Then, by the given data, we have:
[tex]x + y = 1500[/tex]
and
[tex]\dfrac{x}{100} \times 8 + \dfrac{y}{100} \times 6= 106.40\\\\8x + 6y = 10640\\4x + 3y = 5320[/tex]
Thus, we got a system of linear equations as :
[tex]x + y = 1500\\4x + 3y = 5320[/tex]
From equation 1, getting value of x in terms of y, we get:
[tex]x = 1500 - y[/tex]
Substituting this value in second equation, we get:
[tex]4x + 3y = 5320\\4(1500-y) +3y = 5320\\6000 - y = 5320\\y =680[/tex]
Putting this value of y in the equation we got for x,
[tex]x = 1500 - y\\x = 1500 - 680= 820[/tex]
Thus, amount invested by Mrs Ming in account paying 8% interest rate as $x = $820
and for 6% interest paying account, initial amount was $y = $680
Thus,
The amount invested by Mrs. Ming in the account paying 6% was $680

What is the value of x?
Answer:
x = 4
Step-by-step explanation:
Let's look at the ratio of the hypotenuse of both triangles:
25 : 5 = 25/5 = 5
we can see that the measures of the sides of the larger triangle are 5 times those of the smaller triangle.
Therefore, 3x + 8 = 4 x 5
⇒ 3x + 8 = 20
⇒ 3x = 20 - 8 = 12
⇒ x = 12 ÷ 3 = 4
⇒ x = 4
Answer:
x=4
Step-by-step explanation:
As you can see, these triangles are demonstrating a scale factor. It is upscaling by 5. To find out what x is equal to, we need to upscale the smaller side. In this scenario, we have to multiply 4 by 5. This will get you 20. Now we can make an equation.
20=3x+8
We can subtract 8 from both sides.
Now we have:
12=3x
now dividing 12 by 3, we get
x=4
What is the radius of the sector?
Answer:
5 units
Step-by-step explanation:
The area of a sector is [tex]A=\frac{r^2\theta}{2}[/tex] where [tex]r[/tex] is the radius and [tex]\theta[/tex] is the angle formed:
[tex]A=\frac{r^2\theta}{2}\\\\\frac{75\pi}{16} =\frac{r^2(\frac{3\pi}{8})}{2}\\\\150\pi=16r^2(\frac{3\pi}{8})\\\\150\pi=6\pi r^2\\\\25=r^2\\\\5=r[/tex]
Therefore, the radius of the sector is 5 units
A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days). Assume that the number of hours of daylight varies sinusoidal over a period of twelve months. Sketch the graph then use this data to find the following:
We have that the graph will have a solution that is mathematically given as
y=12sin(6t-\pi)+2
Daylight time June trough to December
Question Parameters:
A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days).
Generally the equation for the Amplitude and vertical shift is mathematically given as
[tex]A=\frac{Max+min}{2}\\\\A=\frac{10+14}{2}[/tex]
A=2
vertical shift =[tex]\frac{Max-min}{2}[/tex]
vertical shift =[tex]\frac{14-10}{2}[/tex]
vertical shift =1
Therefore, the time is given as
[tex]t=\frac{2\pi}{b}[/tex]
Where
[tex]b=\pi/6\\\\t=\frac{2\pi}{\pi/6}[/tex]
Hence,The graph will have a solution

Answer:
D. [tex]9(y+3) and 27+9y[/tex]
Step-by-step explanation:
The first expression for each set is using the distributing propety. We can start with the first one. We notice right away that 3 sets of 3y is 9y, when the other expression is 6. So, that is incorrect. Next we see the second one does have a correct y-value, but the integer value of 6 is not the same, since 3*3=9, not 6. For C we can tell that 9*3=27, which is not equal to 12. Therefore, D must be the answer.

The person is 6 feet tall and casts a shadow of 3.2 feet. The building casts a
shadow of 18.5. How tall is the building? Round to the nearest
hundredth.
Answer:
34.69 feet
Step-by-step explanation:
First, you would set up a proportion using the person's measurements and the measurements you do have from the building. You would put your actual value on top of one of the proportions, 6, then put its shadow value, 3.2, on the bottom. Then, you would add 18.5 to the bottom of your other fraction.
Next, you would cross multiply and divide. If you don't know what that means, you will multiply 18.5 by 6, and get 111. Then, divide this number by 3.2. This should make you get 34.6875, so then you round to the nearest hundredths place to get 34.69.

-5(3+6)=-15+30
=15
Answer: 30 should be negative
Step-by-step explanation:
when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45
I think this should be correct, hope this helps!
Answer:
a) The negative was not distributed to the 6
b) -45
Step-by-step explanation:
This simplification uses the distributive property. This is when a factor outside of parentheses is multiplied by the factors within the parentheses. When using this property, if the factor outside the parentheses is negative, then that negative must be distributed to both factors within the parentheses.
The correct way to simplify the expression is as follows:-5(3+6)
Multiply -5*3 and -5*6-15 + -30
Rewrite this using subtraction-15-30

Answer:
the lengths of TA and RP using the distance formula to show that the diagonals are congruent.the slopes of TR, RA, AP and TP to show that one pair of opposite sides is parallel.Step-by-step explanation:
A trapezoid is a four-sided polygon or a quadrilateral. It has one set of opposite sides which are parallel and a set of non-parallel sides.
(Therefore, statement 1 is incorrect and statement 4 is correct)
If the non-parallel sides of the trapezoid are equal in length, then it is called an isosceles trapezoid. An isosceles trapezoid has a line of symmetry and both the diagonals are equal in length.
(Therefore, statement 3 is correct).
Statement 2 is incorrect as the diagonals are NOT perpendicular

Step-by-step explanation:
cost of tip is represented by 25 multiplied by 0.2:
25*0.2=5
add onto original price:
25+5=30
good luck :)
Answer:
$30 dollars
Step-by-step explanation:
Given the following question:
Total price = $25.00
20% tip
In order to find the answer, we find 20% of the 25-dollar haircut. Then we add that number to the original price of the haircut.
[tex]\frac{25\times20}{100} =25\times20=500\div100=5[/tex]
[tex]25+5=30[/tex]

Help please! Find the perimeter of the rectangle.
Answer:
34
Step-by-step explanation:
We know the area is 52 cm and that one length is 13cm. This means that in order to find the missing length, we need to divide 52 by 13. this gives us 4, meaning that the missing side is 4 cm.
Now we add 26 (Double of 13 because it is both sides) to 8 (Double of 4 because they are same lengthening sides)
We then get 34.

Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex]2x^4(2x^2 + 3x + 4)[/tex] is [tex]4x^6 + 6x^5 + 8x^4[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The given expression is simplified as:
[tex]2x^4(2x^2 + 3x + 4) = 2x^4 \times 2x^2 + 2x^4 \times 3x + 2x^4 \times 4\\2x^4(2x^2 + 3x + 4) = 4x^6 + 6x^5 + 8x^4[/tex]
