Answer: 38
Step-by-step explanation:
Answer:
38
Step-by-step explanation:
Let's use benchmark fractions
What is 10% of 40?
that's 40/10 which is 4
What is half of 4?
4/2 = 2
That means 5% of 40 is 2
So then we do 40 - 2 = 38
The other way we can do it is by using percent proportions:
[tex]\frac{x}{95} \frac{40}{100} \\do:\\x=\frac{95 * 40}{100}[/tex]
[tex]x=\frac{3800}{100}[/tex]
[tex]x=38[/tex]

4 (4b + 3) + 2b = 3 (b - 11)
Step-by-step explanation:
4 (4b + 3) + 2b = 3 (b - 11)
16b+12+2b=3b-11
16b+2b-3b=-11-12

The given inequality is solved to obtain as x ≥ 3.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality can be solved as follows,
4x - 5 ≥ 7
Subtract 7 from both sides to obtain,
4x - 5 - 7 ≥ 0
=> 4x - 12 ≥ 0
=> 4x ≥ 12
=> x ≥ 3
The graph for the given inequality is shown as below,
Hence, the solution for the given inequality is x ≥ 3.

If CBA is similar to EDA , find the value of x.
Answer:
1.2
Step-by-step explanation:
The value of 'x' is 1.2 if CBA is similar triangle EDA.
What is similar triangle?Triangles are said to be similar triangle" if they are proportional equality corresponding sides and equal pair of corresponding angles".
According to the question,
∠C =∠E, ∠B=∠D and ∠A=∠A this implies given triangle is inscribed similar right angle triangle.
ΔCBA ≅ ΔEDA [Similar triangle]
Properties of similar triangle: [tex]\frac{CB}{ED} = \frac{BA}{DA}[/tex]
[tex]\frac{6}{7}=\frac{7}{7+x}[/tex]

In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4), F(0,7), G(1,0)
Answer:
[tex]E =[/tex] [tex](-3,3)[/tex]
Step-by-step explanation:
Given
Parallelogram: DEFG
[tex]D(x_1,y_1) = (-2,-4)[/tex]
[tex]F(x_3,y_3) = (0,7)[/tex]
[tex]G(x_3,y_4) = (1,0)[/tex]
Required
Find the coordinates of [tex]E(x_2,y_2)[/tex]
To do this, we make use of mid-point formula which is:
[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]
This gives:
[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
Multiply through by 2
[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]
[tex](-2,3) = (x_2+1,y_2+0)[/tex]
[tex](-2,3) = (x_2+1,y_2)[/tex]
By comparison:
[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]
So, we have:
[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]
[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]
This gives:
[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]
Hence, the 4th coordinate is: [tex](-3,3)[/tex]

In a high school stadium there are 1575 seats. There are two and a half times as many seats in the home section as there are in the visitor section. Which system of equations could be used to determine the number of seats in the home section, h, and the number of seats in the visitor section, v, in the stadium?
Answer:
h = 1,125
v = 450
Step-by-step explanation:
Total number of seats = 1575
h = number of seats in the home section
v = number of seats in the visitor section
There are two and a half times as many seats in the home section as there are in the visitor section.
h = 2 1/2 * v
h = 2 1/2v
Total = h + v
1575 = 2 1/2v + v
1575 = 3 1/2v
1575 = 7/2v
v = 1575 ÷ 7/2
= 1575 × 2/7
= (1575*2) / 7
= 3150 / 7
= 450
v = 450
h = 2 1/2v
= 5/2*450
= 2250/2
= 1,125
h = 1,125
Find the measure of the indicated angle to the nearest degree
A) 18°
C) 48°
B) 42°
D) 26°
Answer:
The answer is option C
Step-by-step explanation:
To find the indicated angle we use sine
sin ∅ = opposite / hypotenuse
From the question
The opposite is 37
The hypotenuse is 41
So we have
sin ? = 37/41
? = sin-¹ 37/41
? = 64.4805
? = 64° to the nearest degree

Find the measure of
Answer:
19 degrees.
Step-by-step explanation:
First solve the angles in the top triangle:
FHG = 180 - 135 = 45 (angles on a straight line = 180)
FGH = 180 - 105 = 75 (angles on a straight line = 180)
Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)
Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60
FDC = 180 - 119 = 61 (anges on a straight line = 180)
Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.
With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).
Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.

Homework: Compound Probability (Without Replacement)
2.) There are three nickels, four dimes, and four quarters in your pocket. You randomly pick three coins and place them on a counter. The first coin is a nickel, the second is a dime, and the third is a quarter.
3/110, 8/165, 1/64, 10/273
3.) A box of chocolates contains four milk chocolates and six dark chocolates. You randomly pick a chocolate and eat it. Then you randomly pick another piece. The first piece is milk chocolate and the second piece is dark chocolate.
4/15, 5/18, 5/22, 3/110
Answer:
For number 2: 8/165
Step-by-step explanation:
The total number of coins = 11 ( 3 + 4 + 4 = 11).
The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).
The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).
The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).
I don't know the other problem, sorry.
Answer:
2) 8/165
3) 4/15
Step-by-step explanation:
2) P(N,D,Q) = 3/11 x 4/10 x 4/9
3) P(M,D) = 4/10 x 6/9
