Answer:
#9 the answer is 7
Step-by-step explanation:
so start with what you know. the sum of the angles in a triangle equal 180 degrees
so...
(x + 13) + (17x - 7) + 48 = 180
now just combine like terms
18x + 54 = 180
18x = 126
x = 7

His grandmother is sick, so Hassan is making a pot of bean soup to bring for dinner. The recipe calls for equal amounts of 3 kinds of beans: kidney, pinto, and black. In all, Hassan uses 2 1/4 cups of beans in the soup.
Use an equation to find the amount of each kind of bean Hassan uses in the soup.
Answers
Answer:
0.75 cup
Step-by-step explanation:
K + p + b = 2 1/4
K = p = b
Sence all beans are equal we can divide 2 1/4 by 3
2 1/4 / 3 = 3/4
Which product is greater than 63?
7/8 x63
3/2 x 63
4/5 x 63
2/3 x 63
Answers
Answer:
The answer is 3/2 x 63
Step-by-step explanation:
3/2*63 = 189 / 2 = 94.5
7/8*63 = 441 / 8 = 55.125
2/3*63 = 126 / 3 = 42
4/5*63 = 252 / 5 = 50.4
Therefore the answer is 3/2 x 63 because it’s product is greater than 63.
What is the equation of this line in slope-intercept form?
A: y = 4x + 1
B: y=−4x+1
C: y=4x−1
D: y=−14x+1
Answers
Answer: B
Step-by-step explanation:
The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.
We can first eliminate C, because the y-intercept of the graph is 1.
To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).
Slope = (y2 - y1) / (x2 - x1)
= (-3 - 5) / (1 - (-1))
= (-3 - 5) / (1 + 1)
= -8/2
= -4
Plug in the slope and y-intercept, we get y = -4x + 1

Which of the triangles in the two figures above is a right triangle? Explain your choice using
the Pythagorean Theorem to prove it. Note: the figures are not drawn to seale.
Answers
Figure B
Step-by-step explanation:The Pythagorean Theorem is [tex]a^2 + b^2 = c^2[/tex], where c is the longest side of the triangle (the hypotenuse).
To find the side length of each square, you have to square root the area of each square. This means that Figure A has side lengths of 3, 6 and 8 units. Figure B has side lengths of 5, 12 and 13 units.
In Figure A, if the triangle is right-angled, the equation [tex]3^2 + 6^2 = 8^2[/tex] must be correct. 9 + 36 = 45. 45 is not equal to 64, so the triangle is not right-angled.
In Figure B, if the triangle is right-angled, the equation [tex]5^2 + 12 ^2 = 13^2[/tex] must be correct. 25 + 144 = 169. 169 is 13 squared, so the triangle is right-angled.
Alternatively, as you are already given the square values for each side length, there is no need to square root and square again. You can just test if the two smaller areas equal the larger area, but the explanation above uses a more detailed example of the Pythagorean Theorem.

See picture for full problem. Please and thank you!
Answers
Step-by-step explanation:
the triangle is an Isosceles triangle
let the another two angles be 2x
and apply angle sum property of triangle here
2x + 72° = 180
2x = 180 - 72
2x = 108
x = 108/2 = 54
therefore,
angle 2 = 54°
a/q
angle 2 = -9 + 7x
now,
54° = -9 + 7x
or
-9 + 7x = 54°
7x = 54 + 9 = 63°
x = 63/7 = 9
x = 9
therefore, value of x is 9.

Which of the following lines has a negative slope?
Is it Red
Is it Black
Is it Blue
Answers
Answer:
black line <3
Step-by-step explanation:
the slope is -2 :)
A negative slop occurs when the rate of change is negative. Looking at the options we have, we can pick a point from each line. The Red line will display a positive slop, the Blue line will display a positive slope, but the Black line will display a negative slope. Therefore, the Black like has a negative slope.

The rational numbers between -3 and -2 are;
-5/2, -9/4 and -11/4
Rational NumbersRational numbers are numbers that can be represented as the quotient of two integers but not equal to zero.
Now, to find the rational number between -3 and -2, we will use the formula;
x = ½(a + c)
x = ½(-3 + (-2))
x = -5/2
Another rational number is;
x = ½(-(5/2) + (-2))
x = ½(-9/2)
x = -9/4
Using the same pattern, we can still get another one as -11/4
In conclusion, the three rational numbers will be -5/2, -9/4 and -11/4

pls help aaaaaaaaaaaa i
Answers
Answer:
According to transitive Property of equality : If a =b and b = c then a = c
In this problem you are given with 2 equations:
h(x) = - 2x + 5 ---- 1
h(x) = 3 ------ 2
Apply transitive Property of equality to equation 1 and 2
- 2x + 5 = 3 Now solve for x.
-2x + 5 - 5 = 3 – 5 subtract 5 on both sides.
-2x = -2
(-2x)/(-2) = (-2) / (-2) Divide with -2 on both sides.
X = 1

Finite geometric series:
Hi, I want to ask a question, is about... for example, take the sequence 1,2,4,8,... Notice that each number is twice the value of the previous number. So, a number in the sequence can be represented by the function f(n) = 2^n-1. One way to write the sum of the sequence through the 5th number in the sequence is E^5 n-1^2n-1. This equation can also be written as S5 = 2^0 + 2^1+2^2+2^3+2^4. If we multiply this equation by 2, the equation becomes 2(S5) = 2^1+2^2+2^3+2^4+2^5.
What happens if I subtract the two equations and solve for S5? Can I use this information to come up with a way to find any geometric series Sn in the form E^a n-1^bn-1?

A wire is bent to form a square of side 22 cm. If the wire is re bent to form a circle, its radius is with steps
Answers
Step-by-step explanation:
the circumference of a circle is
C = 2×pi×r
with r being the radius.
the square side length is 22 cm. so, the circumference or perimeter of the square (and therefore the length of the wire) is
4×22 = 88 cm.
now, it is the same wire of the same length that is now forming a circle.
so, the circumference of the square is also the circumference of the circle.
therefore,
88 = 2×pi×r
44 = pi×r
r = 44/pi = 14.00563499... cm
so, rounded, radius = 14 cm.
Answer:
The other answer is correct
Step-by-step explanation:
The circumference of the circle and the square will be the same so you solve the equation
4*22 = 2 pi r where r is the radius.
