Answer:
it's answer is 73°
Step-by-step explanation:
< DCB = 50°
< ACB = x
< CAB = 57°
< ABC = < DCB = 50° {Being alternate angles }
Now
x + 50° + 57° = 180° { being sum of angles of triangle }
x + 107° = 180°
x = 180° - 107°
Therefore x = 73°
Hope it will help :)❤
A company is making two types of covered aluminum containers. One is a cylinder with a height of 114feet and a diameter of 1 foot. The other is a rectangular prism with a length of 34foot, a width of 34foot, and a height of 1 foot. How much greater is a cylinder's capacity?
Answer:
[tex]V_d=976.9ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of cylinder h_1=114 feet
Diameter d=1
Length of triangular prism [tex]l_2=34ft[/tex]
Width of triangular prism [tex]w_2=34ft[/tex]
Height of triangular prism [tex]h_2=1 ft[/tex]
Generally the equation for Volume of the cylinder is mathematically given by
[tex]V_c=\pir^2h[/tex]
Where
[tex]r=d/2\\r=0.5[/tex]
Therefore
[tex]V_c-=\pi*0.5*114[/tex]
[tex]V_c=57\pi[/tex]
[tex]V_c=179.1ft[/tex]
Generally the equation for Volume of a Rectangular prism is mathematically given by
[tex]V_r=whl[/tex]
[tex]V_r=34*34*1[/tex]
[tex]V_r=1156feet[/tex]
Generally the equation for Volume difference is mathematically given by
[tex]V_d=V_r-V_c[/tex]
[tex]V_d=1156-179.1[/tex]
[tex]V_d=976.9ft[/tex]

Mariah borrowed $1200 to buy a new computer system. She paid the simple interest loan off in 24 monthly payments of $56 each. What was the interest rate of this loan? a.2%
b.6%
c.4.4%
d.7%
Answer:
B. 6%
Step-by-step explanation:
Answer:
6%
Step-by-step explanation:
Her 24 monthly payments total 24 x $56 = $1344
That means that $1344 - $1200 = $144 is just interest. What percent is this of her loan amount? Divide to find out:
144 / 2400 = 0.06 = 6%

2) 2(8r + 5) = 24 + 9r
Answer:
r = 2
Step-by-step explanation:
2(8r + 5) = 24 + 9r
16r + 10 = 24 + 9r
16r - 9r = 24 - 10
7r = 14
r = 2
Which expression is equivalent to 14 x minus 21 over 7 ?
Answer:
-42
Step-by-step explanation:
Which expression is equivalent to 14 x minus 21 over 7 ?
Mathematically this expression is written as:
= (14 × -21)÷ 7
= (14 × -21)/7
= - 294/7
= -42
Therefore, the equivalent of the above expression is calculated as -42
After jumping rope for 15 minutes, Jan took a break. If Jan took a break at 3:05 p.M., at what time did she start jumping rope?
Answer: 2 : 50 pm
Step-by-step explanation:
If Jan took a break at 3:05 pm and she had been jumping rope for 15 minutes before that, to find the time she started jumping rope, subtract 15 from the current time:
= 3:05 - 15
= 2:50 pm
Jan started jumping rope at 2 : 50 pm

How much is Vince paid for one hour of work?
A.
$3.60
B.
$9.00
C.
$9.50
D
$12.00
Answer:
B
Step-by-step explanation:
Using the graph, we pick a convenient point: (20, 180)
This point means that for 20 hours of work, Vincent is paid 180 dollars. In fraction form, we can write 20hrs/180 dollars. If we simplify the fraction by dividing both the numerator and denominator by 20 we get 1/9 AKA 1hr/9 dollars. So in 1 hour, Vinnie is paid $9.00

Answer:
38°
Step-by-step explanation:
The measure of angle NPM is 38°.
➠ ∠MPJ + ∠LPM = 180°
➠ ∠MPJ + 90° = 180°
➠ ∠MPJ = 180° – 90°
➠ ∠MPJ = 90°
∠NPM = ∠MPJ – ∠JPN
➠ ∠NPM = 90° – 52°
➠ ∠NPM = 38°
∴ Required answer :∠NPM = 38°Using the given equation find the missing coordinates o the points and then find the slope of the line for each equation y-2x=3; A(...;6), B(15; ...)
Answer:
(1.5,6)(15,33) slope=2
Step-by-step explanation:
Answer:
y-2x=3; A(1.5, 6) B(15,33) Slope = 2
Step-by-step explanation:
First thing, you add 2x on both sides and get y=2x+3. Since the equation y=mx+b states that m is the slope, the slope is 2.
2nd step is finding the missing coordinate for a. You plug in 6 as the y in the equation y=2x+3, and then get 2x+3=6. Now it is a simple algrebraic equation and you get x=3/2 or 1.5.
The final step is to solve for B. Using the equation y=2x+3, and substituting in x as 15, you get y=30+3 which equals 33.
I hope this gave you an in depth explanation on solving these problems!

In the diagram, PQRS is a rectangular sloping surface, PQTU is a rectangle on horizontal ground and RI and
SU are vertical lines. PQ = SR=UT = 45 cm, QR = PS = 32 cm and angle RQT= 38º.
Calculate
PR,
(b) RT, and
(c) angle RPT
Answer:
(a) PR = 55.2 cm
(b) RT = 19.7 cm
(c) <RPT = [tex]20.8^{o}[/tex]
Step-by-step explanation:
(a) to determine the value of PR, apply the Pythagoras theorem to PQR.
PQ = 45, and SP = QR = 32. So that;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]/PR/^{2}[/tex] = [tex]45^{2}[/tex] + [tex]32^{2}[/tex]
= 2025 + 1024
= 3049
PR = [tex]\sqrt{3049}[/tex]
= 55.218
PR = 55.2 cm
(b) To determine RT, apply the appropriate trigonometric function to QRT.
Let RT be represented by x, so that;
Sin [tex]38^{o}[/tex] = [tex]\frac{x}{32}[/tex]
x = 32 * Sin [tex]38^{o}[/tex]
= 32 * 0.6157
x = 19.7024
RT = 19.7 cm
(c) To determine <RPT, let the angle be represented by θ.
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
= [tex]\frac{RT}{PR}[/tex]
Sin θ = [tex]\frac{19.7024}{55.218}[/tex]
= 0.3568
θ = [tex]Sin^{-1}[/tex] 0.35568
= [tex]20.84^{o}[/tex]
Thus, <RPT = [tex]20.8^{o}[/tex]
A rectangular logo is made up of 3 squares and 8 small squares the length of the rectangle is 36 cm
Find the area of the logo
Answer:
The total area is 594cm.²
Step-by-step explanation:
The top and bottom each have a length of 36 cm.
Blue side:
36/3= 12cm. (36/3 for the length of one side of a blue square)
12*12= 144cm.² (area of one blue square)
144*3= 432cm.² (area of all the blue squares)
Orange side:
36/8= 4.5cm. (the length of one side of an orange square)
4.5*4.5= 20.25cm.² (the area of one orange square)
20.25*8= 162cm.² (the area of all the orange squares)
Total area:
432+162= 594 cm.²
I hope this makes more sense, have a great day :D

Quadrilateral JKLM has side lengths of JK = 2y + 3, KL = 8x – 10, LM = 5y – 6, and JM = 3x + 20. Find the values of x and y that make quadrilateral JKLM a parallelogram. A. X = 6, y = 6 B. X = 6, y = 3 C. X = 13, y = 3 D. X = 2, y = 1
Answer:
(6, 3)
Step-by-step explanation:
Note that the opposite side of parallelogram are congruent, hence;
Jk = LM
2y + 3 = 5y - 6
2y - 5y =-6 - 3
-3y = -9
y = 9/3
y = 3
Similarly;
KL = JM
8x – 10 = 3x+20
8x - 3x = 20 + 10
5x = 30
x = 30/5
x = 6
Hence (x,y) is (6, 3)
