two triangles are similar what is x
Answer:
x = 10
Step-by-step explanation:
smaller triangle / bigger triangle = 20 / 28
hence,
3x / (4x+2) = 20/28
28(3x) = 20(4x+2)
84x = 80x + 40
4x = 40
x = 10
what is the midpoint of the line segment graphed below (-1, 5) (-8, -4)
Answer:
The midpoint is (-4.5,.5)
Step-by-step explanation:
To find the x coordinate, add the x coordinate of the ends and divide by 2
(-1+-8)/2 = -9/2 = -4.5
To find the y coordinate, add the y coordinate of the ends and divide by 2
(5+-4)/2 = 1/2 =.5
The midpoint is (-4.5,.5)

Which expression is the result of solving the equation ax-b=cy for x (For a[tex]\neq[/tex]0)
Answer:
x = (cy+b)/a
Step-by-step explanation:
ax-b=cy
Add b to each side
ax-b+b=cy+b
ax = cy +b
Divide each side by a
ax/a = (cy+b)/a
x = (cy+b)/a

3 * 10 ^3
Step-by-step explanation:
Divide the numbers
3.9 / 1.3

Subtract the powers of 10
10^5 / 10^2 = 10 ^ (5-2) = 10^3
The result is 3 * 10 ^3
[tex] \frac{3.9 \times {10}^{5} }{1.3 \times {10}^{2} } \\ = \frac{3.9}{1.3} \times {10}^{5 - 2} \\ = 3.0 \times {10}^{3} [/tex]

Find the measure of SR.
A.10
B.8
C.7
D.11
The measure of SR is 10.
The given figure has two secant segments and two external segments.
QU = secant segment
QS = secant segment
QP = external segment of QU
QR = external segment of QS
We need to find the measure of SR.
What is the theorem when two secant segments share the same endpoint outside a circle?It states that the product of the length of one secant segment and the length of its external segment equals the product of the length of the other secant segment and the length of its external segment.
Applying the secant theorem in the given figure.
QU x QP = QS x QR
( 9 + 7 ) x 9 = (8 + 3X-5) x 8
16 x 9 = (3 + 3X) x 8
144 = 24 + 24X
144 - 24 = 24X
120 = 24X
X = 120 / 24
X = 5
Now Putting X = 5 in SR = 3X-5
We get,
SR = 3 x 5 - 5
SR = 15 - 5
SR = 10
After applying the secant segment theorem we got the measure of SR as 10.

there are 108 flowers. 1/9 of them bloomed. How many did not bloom? How many did?
Answer:
96 flowers did not bloom and 12 did.
Explanation:
Total flower = 108
Number of flower that bloomed
= ⅑ of the total flowers
= ⅑ of 108
= ⅑ × 108
= 108/9
= 12
So, number of flowers that did not bloom
= Total flowers - Number of flowers that bloomed
= 108 - 12
= 96
So, 96 flowers did not bloom and 12 flowers did.
A textbook store sold a combined total of 255 physics and math textbooks in a week. The number of math textbooks sold was 81 less than the number of physics textbooks sold. How many textbooks of each type were sold?
Answer:
math = 87
physics = 168
Brainliest, please!
Step-by-step explanation:
Variables:
m = math, p = physics
Equations:
m + p = 255
m = p - 81
Substitution:
m + p = 255
(p - 81) + p = 255
2p - 81 = 255
2p = 336
p = 168
Solving for m:
m + p = 255
m + 168 = 255
m = 255 - 168
m = 87
Checking with the other equation:
m = p - 81
87 = 168 - 81
87 = 87
So, math = 87 and physics = 168

What is the domain of f(x) = 5x – 7?
{x | x > –7}
{x | x < –7}
{x | x > 0}
{x | x is a real number}
Answer:
{x | x is a real number}
Step-by-step explanation:
f(x) = 5x – 7
There are no restrictions on the value that x can take
The domain is all real numbers
Answer:
In the given expression, that is, f (x) = 5x - 7, we can say:
x satisfies all the real values starting from -∞ to ∞.
domain of 5x-7
Interval notation for f (x):
(- ∞ , ∞)
So, the domain will be all real numbers, as the function is a straight line, with no discontinuities, thus undefined at no value of x.

Consider this polynomial, where a is an unknown real number.
p(t) = x^4 +5x^3 + ax^2 - 3x + 11
The remainder of the quotient of P(x), and (x+ 1) is 17.
Braulio uses synthetic division to find the value of a, and Zahra uses the remainder theorem to find the value of a.
Answer:
Brauilo is wrong because he divided by (x+1) instead of (x-1)
Step-by-step explanation:
The remainder Theorem states that
if polynomial f(x) is divided by binomial x-a, the remainder will equal f(a). The factor is positive so the binomial is the same as
which is why we divide by -1, or subsitue -1 into the equation p(x).
The remainder of a polynomial division can be gotten using remainder theorem or synthetic division.
The true statement is: Brauilo did not find the value of a, because he divided by (x+1) instead of (x-1)
From the question, we have the following parameters:
[tex]\mathbf{p(x) = x^4 +5x^3 + ax^2 - 3x + 11}[/tex]
[tex]\mathbf{Divisor =x+ 1}[/tex]
[tex]\mathbf{Remainder = 17}[/tex]
First, we set the divisor to 0.
[tex]\mathbf{Divisor =x+ 1 = 0}[/tex]
So, we have:
[tex]\mathbf{x+ 1 = 0}[/tex]
Solve for x
[tex]\mathbf{x= -1}[/tex]
The above equation means that, the value of x that will be used to test the polynomial is -1
From the question,
Zahra used [tex]\mathbf{x= -1}[/tex]; this is represented as: P(-1)Braulio used [tex]\mathbf{x= 1}[/tex]; this is represented in the synthetic divisionHence, Braulio is incorrect, because he used the wrong value of x

The ratio of the volumes of two spheres is 827. What is the ratio of the lengths of the radi of these two spheres?
23
Answer:
2:3
Step-by-step explanation:
r_1^3:r_2^3=8:27
r_1:r_2=2:3
Answer:
2/3
Step-by-step explanation:
solve volume formula for r and then use v1 and v2 from the ratio to find r1 and r2
v = 4/3 Pi r**3
(3/4 v) / Pi = r**3
r = (3v/4Pi)**1/3
Then
r1 = (3*8/4pi)**3
= (6/Pi)**1/3
= 1.24
r2 = (3*27/4Pi)**3
= (81/4Pi)**3
= (6.45)**3
= 1.8
Then
r1/r2 = 1.24/1.8 = .6666666 or 2/3
