Answer:
the solution to the inequality is x<-10
Answer:
x<−10
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
7x−26>9x−6
Step 2: Subtract 9x from both sides.
7x−26−9x>9x−6−9x
−2x−26>−6
Step 3: Add 26 to both sides.
−2x−26+26>−6+26
−2x>20
Step 4: Divide both sides by -2.
-2x/-2 > 20/-2
x<−10

Answer:
sin(30)° = [tex]\frac{10}{x}[/tex]
Step-by-step explanation:
By applying sine rule in the given triangle,
sin(30)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(30)° = [tex]\frac{10}{x}[/tex]
[tex]\frac{1}{2}= \frac{10}{x}[/tex]
x = 2 × 10
x = 20
Therefore, answer will be sin(30)° = [tex]\frac{10}{x}[/tex].
10= 3(3) + b what is the slope and y-intercept
Answer:
slope: 3
y-intercept: 1
slope-intercept form equation: y = 3x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
the equation you're given, 10 = 3(3) + b, is already in slope-intercept form and also already has the slope identified (it's 3!) so thankfully that's one less thing to solve for! :)
all you have to do now is solve for b.
first, multiply 3(3).
10 = 3(3) + b
10 = 9 + b
then subtract 9 from both sides of the equation. 9 and -9 cancel each other out, so the only thing you have to do for this step is subtract 9 from 10.
10 - 9 = b
1 = b aka b = 1
and now you have your b value!
so your slope is 3 and your y-intercept is 1.

9514 1404 393
Answer:
a) $215,892.50
c) $220,803.97
e) $222,534.58
f) $222.554.09
Step-by-step explanation:
The compound interest formula is ...
FV = P(1 +r/n)^(nt)
where principal P is invested at annual rate r for t years, compounded n times per year. In this problem, you have P=100,000, r=0.08, t=10, and the only variable of interest is n.
When calculations are repeated, it is often convenient to let a calculator or spreadsheet do them. You only need to program the formula once, then use it for the different values of the variable of interest. Most spreadsheets have this formula built in, so you don't even need to program it.
__
For continuous compounding, the formula is ...
FV = Pe^(rt)
FV = 100,000e^(0.08·10) = 222,554.09
Danny is building a pyramid modeled after one of the great pyramids of Giza in Egypt .The great pyramid has a height of 480 feet and a square base with each side measuring 755 feet if Danny builds the pyramid to one hundredths (1/100) the size what will the volume be for his pyramid
Answer:
91.204 cubic feet
Step-by-step explanation:
We are given that
Height of great pyramid, h=480feet
Side of square base, a=755 feet
Height of Danny's pyramid, h'=480/100 feet
Side of square base of Danny's pyramid, a'=755/100 feet
We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.
We know that
Volume of square base pyramid, V=[tex]\frac{1}{3}a^2h[/tex]
Where a= Side of base
h=Height of pyramid
Using the formula
Volume of Danny's pyramid=[tex]\frac{1}{3}\times(755/100)^2(480/100)ft^3[/tex]
Volume of Danny's pyramid=91.204 cubic feet
Alexandra's drafting class is building a scale model of the school's courtyard. Alexandra chose to make a model of a campus oak tree for the assignment as shown. The tree is 10 yards tall and the base of the tree is 5 yards away from the edge of a park bench. She calculated that her oak tree model should be 0.4 yards tall. What is the distance, in yards, from the base of the model tree to the edge of the model bench?
Answer:
It's 0.20
Step-by-step explanation:
The distance between the base of the model tree to the edge of the model bench is 0.2 yard.
Similar triangle :A diagram is attached which describe the statement of question.
From diagram attached below, It is observed that both triangles are similar triangles.
The ratio of corresponding sides are same in the similar triangles.
the distance between the base of the model tree to the edge of the model bench is x.

Find the value of x that makes the quadrilateral a parallelogram
What is x?
To make it a parallelogram, the diagonals have to bisect each other (6x=3x+2)
Calculate and you will get x = 2/3
The value of x that makes the quadrilateral a parallelogram is 2/3.
What is a parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
We have a quadrilateral.
To show that the quadrilateral is a parallelogram:
If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
That means,
6x = 3x + 2
3x = 2
x = 2/3
Therefore, the value of x is 2/3.

△KJL~△WJX. Identify the coordinates of X and the scale factor.
PLZ help
Answer:
X(−64/3, 0); 8/3
Step-by-step explanation:
To find the coordinates of the point X, first find the scale factor for a dilation of two similar triangles in the coordinate plane
To determine the scale factor, set up a ratio of the lengths of two corresponding sides of the triangles.
Use the Distance Formula d=(x2−x1)2+(y2−y1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√ to find the length of the sides JK and JW.
Point J is the origin. Thus, the coordinates of the point J are (0,0).
It is given in the figure that the coordinates of the point K are (0,6).
To find JK, substitute x1=0, x2=0, y1=0, and y2=6 into the distance formula.
JK=(0−0)2+(6−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√=62‾‾√=6
The length of JK is 6.
It is given in the figure that the coordinates of the point W are (0,16).
To find JW, substitute x1=0, x2=0, y1=0, and y2=16 into the distance formula.
JW=(0−0)2+(16−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√=162‾‾‾‾√=16
The length of JW is 16.
To determine the scale factor, set up a ratio of the lengths of two corresponding sides, JW and JK, of the triangles.
JWJK=166=83
The scale factor is 83.
To find the coordinates of the point X multiply the coordinates of the point L by the scale factor.
It is given in the figure that the coordinates of the point L are (−8,0).
X(−8⋅83,0⋅83)=X(−643,0)
The coordinates of the point X are (−643,0).
The figure shows the same triangles K J L and W J X as in the beginning of the task. Point X is at minus 64 thirds, zero.
Therefore, the coordinates of X is (−643,0) and the scale factor is 83.

Stuff mart sells ice cream toppings in two different packages. Package one has eight blueberry toppings for $22. Package two has four blueberry and seven strawberry toppings for $22. Find the cost of each topping
Answer:
the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
Step-by-step explanation:
The computation is shown below:
Let us assume the blueberry topping be x
And, the strawberry topping be y
Now as per the question
8x = $22
Divide by 2 to the both sides
4x = $11
x = $11 ÷ 4
= $2.75
And,
4x + 7y = $22
Now put the x value in the above equation
4 × (11 ÷ 4) + 7y = $22
11 + 7y = $22
7y = $22 - $11
7y = $11
y = $11 ÷ 7
= $1.57
Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
