Subtract —b+3 from —11b —4
Answer:
Step-by-step explanation:
STEP 1:
-11b-4-(-b+3)....bracket the equation that you are subtracting and add a mins sign infront of the bracket because you are asked to subtract -b+3 from -11b-4.
STEP 2:
-11b-4+b-3
the minus sign infront of the bracket changes the minus sign to a positive (+)sign because a minus(-) timesed by a minus is a positive(+). and a minus timesed by a positive(+) is a negative(-)
STEP 3:
-10b-7
add the b values together(11b-b) = 10b
add the numericals together -4+(-3)= -7
STEP 4:
final answer is -10b-7

Find 66 2/3 precent of 87. Find 1 precent of 3,620
62 1/2 precent of x is 5 what is x. 300 precent of k is 42 what is k
Final answer:
To find percentages of numbers, convert the percent to a decimal and then multiply. To find the unknown quantity in an equation involving percentages, divide the given number by the percent expressed as a decimal.
Explanation:
To find 66 2/3 percent of 87, first convert the percent to a decimal by dividing it by 100: 66 2/3 ÷ 100 = 0.6667. Then multiply the decimal by 87: 0.6667 x 87 = 58.33. So, 66 2/3 percent of 87 is approximately 58.33.
To find 1 percent of 3,620, divide 3,620 by 100: 3,620 ÷ 100 = 36.2. So, 1 percent of 3,620 is 36.2.
To find x in the equation 62 1/2 percent of x is 5, first convert the percent to a decimal: 62 1/2 ÷ 100 = 0.625. Then divide 5 by the decimal: 5 ÷ 0.625 = 8. So, x is 8.
To find k in the equation 300 percent of k is 42, first divide 42 by 300: 42 ÷ 300 = 0.14. So, k is 0.14.

The triangle given has base 60 and height 45
The scale says "1 unit:5 meters" which means that each unit on the grid is 5 meters. We can divide each dimension of the given triangle by 5 so we figure out how many units we'll need for each dimension of the new smaller triangle (that is similar to the original)
60/5 = 12
45/5 = 9
The smaller triangle must have a base of 12 and a height of 9
See the diagram below.
The area of this new triangle is (base*height)/2 = (12*9)/2 = 108/2 = 54 square units.
a set of golf clubs is marked at 25% off. If the regukar price is $630, find the discount and sale price
Answer:
472.5
Step-by-step explanation:
This one is simple.
They way you figure this out is your times the amount of money for the original cost by the discout so the equation is 630 times .25 equals 157.5. You then take that disount price and minus it from the original price, which is 630 so the eqation 630 minus 157.5 equals 472.5.

find an equation of the line such that the points (2/5,5) and (-2/5,4) are on the line.
The equation of the line is y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
The form of the linear equation is y = mx + b, where
m is the slope of the line, [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] b is the y-intercept, to find b substitute x and y in the equation by the coordinates of any point on the line∵ A line passes through points ( [tex]\frac{2}{5}[/tex] , 5) and ( [tex]-\frac{2}{5}[/tex] , 4)
∴ [tex]x_{1}[/tex] = [tex]\frac{2}{5}[/tex] and [tex]x_{2}[/tex] = [tex]-\frac{2}{5}[/tex]
∴ [tex]y_{1}[/tex] = 5 and [tex]y_{2}[/tex] = 4
- Substitute them in the rule of the slope to find m
∵ [tex]m=\frac{4-5}{-\frac{2}{5}-\frac{2}{5} }[/tex]
∴ [tex]m=\frac{-1}{-\frac{4}{5}}=\frac{5}{4}[/tex]
- Substitute it in the form of the equation
∴ y = [tex]\frac{5}{4}[/tex] x + b
- To find b substitute x and y in the equation by the coordinates
of any point on the line
∵ Point ( [tex]\frac{2}{5}[/tex] , 5) lies on the line
∴ x = [tex]\frac{2}{5}[/tex] and y = 5
∴ 5 = [tex]\frac{5}{4}[/tex] ( [tex]\frac{2}{5}[/tex] ) + b
∴ 5 = [tex]\frac{1}{2}[/tex] + b
- Subtract [tex]\frac{1}{2}[/tex] from both sides
∴ [tex]\frac{9}{2}[/tex] = b
∴ y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{9}{2}[/tex]
The equation of the line is y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{9}{2}[/tex]

c. sin 60°= square root of 48 over 8
d. tan 30°= square root of 48 over 8
Answer:
Option d is incorrect.
Step-by-step explanation:
See the diagram attached.
a. [tex]\sin 30^{\circ} = \frac{AB}{AC} = \frac{4}{8}[/tex]. Hence, this is correct.
Here, sin Ф is given by perpendicular divided by the hypotenuse.
b. [tex]\cos 60^{\circ} = \frac{AB}{AC} = \frac{4}{8}[/tex]. Hence, this is also correct.
Here, cos Ф is given by base divided by the hypotenuse.
c. [tex]\sin 60^{\circ} = \frac{BC}{AC} = \frac{\sqrt{48}}{8}[/tex]. Hence, this is also correct.
d. [tex]\tan 30^{\circ} = \frac{AB}{BC} = \frac{4}{\sqrt{48}}[/tex]. Hence this is not correct.
Here, tan Ф is given by perpendicular divided by base.
Therefore, option d is incorrect. (Answer)

You work for 6.5 hours at a rate of $11.50 / hour.
You buy dinner that costs $12, and give a 20% tip.
How much money are you left with?
Answer:
[tex]\$60.35[/tex]
Step-by-step explanation:
step 1
Find the total amount of money worked
Multiply 6.5 hours by the rate $11.50 / hour.
[tex]6.5(11.50)=\$74.75[/tex]
step 2
Find the total cost of the dinner
Remember that
[tex]100\%+20\%=120\%=120/100=1.2[/tex]
so
the cost of the dinner plus the tip is equal to
[tex]\$12(1.2)=\$14.4[/tex]
step 3
Find the amount of money left
Subtract the total cost from the total amount of money
so
[tex]\$74.75-\$14.4=\$60.35[/tex]
Tricia completed the square of the quadratic function f(x) = x² + 14x + 2 and determined the coordinates of the minimum value are (-7, - 47). Which equation must be Tricia's result?
f(x = (x +7)² + 47
f(x) = (x + 7)² - 47
f(x) = (x - 7)² + 47
f(x) = (x - 7)² - 47
Answer:
The co-ordinates which give the minimum value for the quadratic function are (-7, -47)
Step-by-step explanation:
i) the quadratic function f(x) = [tex]x^{2}[/tex] + 14x + 2
= [tex]x^{2}[/tex] + 14x + 49 - 49 + 2
= [tex](x + 7)^{2}[/tex] - 49 + 2
= [tex](x+7)^{2}[/tex] - 47
ii) The minimum value of the result of the quadratic equation in i) will be achieved when [tex](x + 7)^{2}[/tex] is zero as any square value is always positive and thus the minimum value of a square is always zero.
iii) [tex](x + 7)^{2}[/tex] is zero when x = -7 and when x = -7 then y = f(x) = -47
iv) The co-ordinates which give the minimum value for the quadratic function are (-7, -47)
The diameter of the sun is about 1.39 × 10^6 kilometers. The diameter of the Earth is about 1.27 × 10^4 kilometers. How many times larger in diameter is the sun than the Earth? Write your answer in scientific notation, and round the coefficient to the nearest hundredths place.
Answer:
1.09 x 10^2
Step-by-step explanation:
1.39 x 10^6 / 1.27 x 10^4 = 1.09448818898
1.09448818898 is rounded 1.09
10^6-4 = 10^2
So, 1.09 x 10^2
The sun is approximately 109.29 times larger in diameter than the Earth.
Explanation:To determine how many times larger in diameter the sun is compared to the Earth, we divide the diameter of the sun by the diameter of the Earth.
The diameter of the sun is 1.39 × 106 kilometers, while the diameter of the Earth is 1.27 × 104 kilometers.
Dividing the diameter of the sun by the diameter of the Earth, we get (1.39 × 106) / (1.27 × 104) = 109.29.
Therefore, the sun is approximately 109.29 times larger in diameter than the Earth.

Consider g(x) = −x^2 + 12x − 32 Part A: Write g(x) in vertex form, identify the vertex, and determine the x-intercepts.
Answer:
(x - 6)² = - (y - 4)
The vertex of the parabola will be (6,4).
The x-intercepts are at (8,0) and (4,0).
Step-by-step explanation:
Given the equation of parabola is g(x) = y = - x² + 12x - 32 .......... (1)
Now, converting the equation to vertex form.
Here, y = - x² + 12x - 32
⇒ y = - (x² - 12x + 36) + 4
⇒ y - 4 = - (x - 6)²
⇒ (x - 6)² = - (y - 4) ........... (2) (Answer)
Now, the vertex of the parabola will be (6,4) and it opens down. (Answer)
Let the x-intercept of the parabola is at (h,0).
Hence, from equation (2) we get,
(h - 6)² = - (0 - 4) = 4
⇒ h - 6 = ± 2
⇒ h = 8 or h = 4
Therefore, the x-intercepts are at (8,0) and (4,0). (Answer)

What are the missing measures in the diagram
Answer:
J=67
T=67
G=180-67-67
St=5
HJ=3.7
Step-by-step explanation:
The two triangles are equal.
Since the triangle at isosceles, two sides/angles are equal.
The measure of the angles and the sides are:
m∠J = 67
m∠T = 67
m∠G =46
ST = 5 cm
HJ = 3.7 cm
We have,
ΔGHJ ≡ Δ STU
This means,
The corresponding sides and angles are the same.
Now,
GH = ST = GJ = SU = 5cm
And,
HJ = TU = 3.7 cm
Now,
The sum of the angles in the triangle = 180
In GHJ,
m∠J = 67
This is because angles opposite to the equal sides are the same.
Now,
∠G + ∠H + ∠J = 180
∠G + 67 + 67 = 180
∠G = 180 - 134
m∠G = 46
And,
m∠T = 67
Since ΔGHJ ≡ Δ STU.
Thus,
The measure of the angles and the sides are:
m∠J = 67
m∠T = 67
m∠G =46
ST = 5 cm
HJ = 3.7 cm

4x-y=-1 what is the answer
Answer:
X= -9/10
y= -2 3/5
Step-by-step explanation:
Multiply equation one by 4 and equation two by 3 to eliminate X
it becomes
-12x + 8y =-12
12x - 3y = -1
add equation one and two,
you'll be left with 5y= -13
divide both sides by 5
y = -13/5 improper fraction
= -2 3/5
Now substitut y = -2 3/5 into any of the original equations to get x.
using equation two, we have
4x -(-2 3/5) = -1
4x + 2 3/5 = -1
4x = -1 - 2 3/5
the LCM of 5 is 5 , so
4x = -5-13/5
4x = -18/5
crossmultiply
4x x 5 = -18
20x = -18
divide both sides by 20
we have x = -18/20, when you cancel further , you have x = -9/10

If two or more points have the same domain or x value, then it is not a function because points cannot have identical x values, only y values.
With this in mind, C is not a function because there are two 4s in the domain.
So looking at this our answer would be C because when you are trying to find if it is not a function you have to look for repeated X values or domains if there I s a problem with a repeated X value that would not be a function but if the Y values were to repeated that doesn’t really matter so yeah.
