Answer:
y= 77° x=103°
Step-by-step explanation:
x=103° Alternate angles are equal
y=77° angles on a straight line sum to 180° (180°-103°=77°)
Answer:
For x, we can justify that x=103° and for y, we can justify that it equals 77°.
Step-by-step explanation:
X°: VERTICAL ANGLE THEOREM, or if angles are opposite of each other and are formed by two intersecting straight lines, then they are congruent.
Thus, x°=103°
Y°: SUPPLEMENTARY ANGLE THEOREM, or if two angles are supplementary to the same angle, then the two angles are said to be congruent.
Thus, y°=77°

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2+1 inches. She plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. What expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5?
2x2+4x−6; 22.0 inches
2x2+4x−6; 32.5 inches
4(2x2+4x−6;) 88.0 inches
4(2x2+4x−6;) 130.0 inches
Answers
Answer:
4(2x2+4x−6;) 130.0 inches
Step-by-step explanation:
The expression that can be used for the total length of ribbon she needs for both square pillows and the length if x = 3.5 is:
D. 4(2x² + 4x - 6); 130.0 inches.
What is the Perimeter of a Square?Perimeter of a square = 4(s).
s = side length of the square.
Perimeter of the first pillow = 4(s) = 4(2x² + 1) inches.
Perimeter of the similar pillow = 4(s) = 4(4x - 7) inches.
Expression for the total length of ribbon she will need for both square pillows is:
4(2x² + 1) + 4(4x - 7)
4(2x² + 1 + 4x - 7)
4(2x² + 4x - 6)
If x = 3.5, plug in the value of x into 4(2x² + 4x - 6) to find the total length of the ribbon she needs:
4(2(3.5)² + 4(3.5) - 6)
4(24.5 + 14 - 6)
130.0 inches.
Thus, the expression that can be used for the total length of ribbon she needs for both square pillows and the length if x = 3.5 is:
D. 4(2x² + 4x - 6); 130.0 inches.

9. a. 6
9. b. 2; 1
9. c. 3.14; 1.57
9. d. 7.57
10. 3106.86
Step-by-step explanation:
9. a. The rectangle has a length of 3 and a width of 2, so that means its area has to be 6.
9. b. The semi-circle's diameter is 2, because it is the same width as the rectangle, and finding the radius, means that you need to cut the diameter in half, so the radius of the circle is 1.
9. c. To find the full circle, we must use the formula (pi)(r)^2. So we have 3.14(1), which is just equal to pi. but since we need half the circle, we must divide the number by 2, to get the answer 1.57...
9. d. Finally we need to add up all the values together, from a. we know that the rectangle has an area of 6, and from b and c, we know the semi-circle has an area of 1.57, so we add those two numbers together we get 7.57.
10. We can do the exact same thing as number nine, which means the rectangle is 30*70=2100, The radius of the circle is 15 (30/2), the area of the circle (and since there are 2 semi circles, we don't need to divide by 2) we get 706.86, now all thats left is to add the numbers together to get the number 2806.86.

Answers
Answer:
In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

what is the least perfect squared number that is divisible divisible by
12
16
20
24
NOTE : the first one who answers gets branilast
Answers
The lowest perfect squared number that is divisible by 12,16,20,24 is 3600
1. Let's find the L.C.M
12 = 2×2×3
16 = 2×2×2×2
20 = 2×2×5
24 = 2×2×2×3
The L.C.M is 2×2×2×2×3×5 = 240
2. Now, the L.C.M 240 is not a perfect square.
3.Therefore to obtain a lowest perfect square the given number should be should have another 3 and 5 as the factor.
4. So, multiplying 240 by 15 we, get 3600 which is a perfect square and it can be divided by 12,16,20,24.
5. 3600 is the square of 60.
6.Therefore, the lowest perfect square that is divisible by 12,16,20,24 is 3600

Step-by-step explanation:

7. [tex]a=48[/tex]
8. [tex]b=30[/tex]
9. [tex]c = 188[/tex]
10. [tex]d = 18[/tex]
11. [tex]x = 32[/tex]
12. [tex]y = 40[/tex]
Step-by-step explanation:
Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.
[tex]\frac{33}{a} = \frac{11}{16}[/tex]
[tex]11 a = 33(16)[/tex]
[tex]11a = 528[/tex]
Now we can simplify.
