7 is increased by 11 so you decrease it by 11
7-11= -4
3 is decreased by 1 so you increase it by 1
3+1= 4

Santiago buys a new television for $989.76. If
the sales tax rate is 8.75%, what is the total cost
of the television?
Answer:
$1076.36
Step-by-step explanation:
The full price before tax can be represented by 1.00($989.76), and the 8.75% tax by 0.0875($989.76)
which can be combined to obtain the total cost: (1.0875)($989.76) = $1076.36

The ages of two groups of karate students are shown in the following dot plots:
A dot plot shows Age in years on the horizontal axis. For Group A, there are 2 dots on 4, 5 dots on 5, 3 dots on 7, 4 dots on 8, 2 dots on 9, 2 dots on 11, and 1 dot on 14. For Group B, there is 1 dot on 7, 2 dots on 8, 1 dot on 9, 1 dot on 11, 1 dot on 16, 2 dots on 19, 2 dots on 20, 2 dots on 21, and 1 dot on 26.
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean.
Answer:
Group A has greater variability in the data.
Step-by-step explanation:
We use elimination. Clearly, from the MAD, Group A has greater variability in the data.
So, choice 1.
There are 250 students in a class the ratio of boys to girls is 3:2 how many boys are there?
Answer:
total no of children = 250
let no.of boys be = 3x
let no.of girls be = 2x
equation = 3x+2x= 250
= 5x= 250
= x= 250\5
= x= 50
so, no,of boys = 3x = 3x50 = 150
and no,of boys = 2x = 2x50 = 100
heres ur ans ,

Given:
The figure of a rhombus QRST.
To find:
A. The value of x.
B. The measure of angle RQP.
Solution:
A. We need to find the value of x.
We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.
[tex]m\angle RPS=90^\circ[/tex] [Right angle]
[tex](5x+15)^\circ=90^\circ[/tex]
[tex](5x+15)=90[/tex]
[tex]5x=90-15[/tex]
[tex]5x=75[/tex]
Divide both sides by 5.
[tex]x=\dfrac{75}{5}[/tex]
[tex]x=15[/tex]
Therefore, the value of x is 15.
B. We need to find the measure of angle RQP.
From the given figure, it is clear that
[tex]m\angle RQP=(2x+3)^\circ[/tex]
Putting [tex]x=15[/tex], we get
[tex]m\angle RQP=(2(15)+3)^\circ[/tex]
[tex]m\angle RQP=(30+3)^\circ[/tex]
[tex]m\angle RQP=33^\circ[/tex]
Therefore, the measure of angle RQP is 33 degrees.

Step-by-step explanation:
Here is the complete question. Please find attached a diagram showing the scaled and real drawing
Use the given scale factor and the side lengths of the scale drawing to determine the side lengths of the real object
A. side a is 7 inches long, side b is 6 inches long,and side c is 3 inches long
B. side a is 30 inches long, side b is 25 inches long, and side c is 20 inches long
C. side a is 40 inches long, side b is 35 inches long,and side c is 20 inches long
D. side a is 175 inches long,side b is 150 inches long, and side c is inches long
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
The scaled drawing is an enlarged image of the original triangle.
It is enlarged at a ratio of 5:1
original dimensions
a = 35/5 = 7
b = 30 / 5 = 6
c = 15/5 = 3

Solve for x and graph the solution on the number line
15 > 2x – 9 > -23
The answer is 12>x>-7
Step-by-step explanation:
it's first divided into 2 parts
1 . 15 > 2x - 9
2. 2x - 9 > -23
Then solve them individually.
let's do it,
First half
15 > 2x - 9
15+9 > 2x
24 > 2x
24/2 > x
12>x
Second half
2x-9>-23
2x>-23+9
2x>-14
x>-14/2
x>-7
Joining of the two halves
We have :
12>x>-7

In one area, the lowest angle of elevation of the sun in winter is 28°. Find the minimum distance x that a plant needing full sun can be placed from a fence that is 6 feet high. Round your answer to the tenths place
Answer:
[tex]l_d=11.28ft[/tex]
Step-by-step explanation:
From the question we are told that:
Angle [tex]\theta=28 \textdegree[/tex]
Height of Fence [tex]h=6 feet[/tex]
Generally the equation for Length of shadow cast by the fence is mathematically given by
Since
Shadow cast forms a right angle triangle
[tex]l_d=\frac{h}{tan \theta}[/tex]
[tex]l_d=\frac{6}{tan 28}[/tex]
[tex]l_d=\frac{6}{tan 28}[/tex]
[tex]l_d=11.28ft[/tex]
Therefore the minimum distance x that a plant needing full sun can be placed from a fence that is 6 feet high is
[tex]l_d=11.28ft[/tex]
Find the slope-intercept equation of the line that passes through (2,-5) and has a slope of 1/3
Answer:
y = 1/3x - 17/3
Step-by-step explanation:
Given:
Passes through (2, -5)
m = 1/3
Slope-intercept:
y - y1 = m(x - x1)
y - (-5) = 1/3(x - 2)
y + 5 = 1/3x - 2/3
y = 1/3x - 17/3
Jason poured 1 gallon 1 quart of water into an empty 2-gallon bucket. How much more water can be added to reach the bucket's 2-gallon capacity?
Answer: 3 quart
Step-by-step explanation:
Given
Jason poured 1 gallon 1 quart of water into an empty 2 gallon bucket
1 gallon can be written as 4 quart
So, 2 gallon can be written as 8 quart
Subtract 1 gallon 1 quart(5 quart) from 2 gallon(8 quart) to get the volume added
[tex]\Rightarrow 8-5\\\Rightarrow 3\ \text{quart}[/tex]
So, 3 quart of water must be added to reach 2 gallon capacity.

The three point line on a basketball court forms a semi circle. For middle school, it has a diameter of 34 feet. What is the area of the semi circle?
Answer:[tex]454.019\ ft^2[/tex]
Step-by-step explanation:
Given
Diameter of semi-circle is [tex]d=34\ ft[/tex]
So, its radius is [tex]r=\dfrac{34}{2}=17\ ft[/tex]
Area of semi-circle is [tex]\dfrac{\pi r^2}{2}[/tex]
[tex]\therefore \text{Area of semi-circle is }=\dfrac{\pi r^2}{2}\\\\\Rightarrow A=\dfrac{\pi \cdot 17^2}{2}\\\\\Rightarrow A=454.019\ ft^2[/tex]
Thus, the area of semi-circle is [tex]454.019\ ft^2[/tex]

John receives a $20000 salary for working as an agent. If John has to spend $11000 of his salary on expenses each year, then what percent of John's money does he have to spend?
Answer:
55%
Step-by-step explanation:
Percent spent = (amount spent / total income) x 100
( $11000 / $20000) x 100 = 55%
which does not describe the equation
[tex] \sqrt{x = - 2} [/tex]
Answer:
which of what ?
and the equation is not right. I don't know what you mean.
do you mean x = sqrt(-2) ?
all I can tell you just based on that assumption is that you can transform that into
[tex]x = \sqrt{2} \times i[/tex]
you know,
[tex]i = \sqrt{ - 1} [/tex]
but what else you might need is completely unclear.
Help me with the question
Answer:
y_2 is 8 units
Step-by-step explanation:
Given that
The distance between the point is 13 units
x_1 is 5
y_1 is 3
x_2 is -7
We need to find out the y_2
So, the following formula should be used
[tex]d = \sqrt({x_2 - x_1})^2 + (y_2 - y_1)^2\\\\13 = \sqrt({-7-5})^2 + (y_2 - 3)^2\\\\169 = 144 + (y_2)^2 + (-3)^2 - 2(y_2) (-3)\\\\25 = (y_2)^2 + 9 - 6y_2\\\\16 = (y_2)^2 -6y_2\\\\(y_2)^2 -6y_2 - 16 = 0\\\\(y_2)^2 - 8y_2 + 2y_2 - 16 = 0\\\\y_2 (y_2 - 8) + 2(y_2 - 8) = 0\\\\y_2 = 8[/tex]
hence, y_2 is 8 units

Answer:
Hi there! The correct answer should be: x is 60 degrees
Step-by-step explanation:
okay, so the equation is:
2x + 60 = 180
which we will solve:
2x + 60 - 60 = 180 - 60
2x = 120
x = 60
Compare. Use <, >, and =.

If f(x)=7(x-1)+8f(x)=7(x−1)+8 , what is the value of f(1)f(1) ?
Answer:
8
Step-by-step explanation:
All you have to do is plug in 1 for the x value, which leaves you with the equation 7(1-1) + 8, then you simplify it to be 7(0) + 8
7 times 0 is 0, so you are left with 8 as your answer
if one of the factor of x²+x-20 is (x+5) find other factor
Answer:
Step-by-step explanation:
x^2+x-20
=x^2-(5-4)x-20
=x^2-5x+4x-20
=x(x-5)+4(x-5)
=(x-5)(x+4)
therefore the other factor is (x+4)
Answer:
(x - 4)
Step-by-step explanation:
METHOD 1 (Long Division Method):-
[See the attachment for full solution of Method 1]
One factor of x² + x - 20 is already given. To find the other factor , divide the polynomial with the factor and the quotient you'll get after dividing will be the second factor of the polynomial.
METHOD 2 (Factorising) :-
Factorise x² + x - 20.
Split the middle terms.[tex]=> x^2 + 5x - 4x - 20[/tex]
Take 'x' common from first two terms and take '-4' common from last two terms.[tex]=> x(x + 5) - 4(x + 5)[/tex]
Take '(x+5)' whole common from the expression.[tex]=> (x + 5)(x - 4)[/tex]
(x + 5) & (x - 4) are the factors of x² + x - 20.
