Answer: y= -4/5 and x= 29/5
Step-by-step explanation:
From eqn2 , x= 5-y. Thus substituting in eqn1 will give
6(5-y)-4y=38
30-6y-4y=38
30-10y=38
-10y=38-30
-10y= 8
y=8/-10---> y= -4/5
Substituting y in eqn2 we have
x+(-4/5)=5
x=5+4/5
x=29/5

Exactly 4 households have a cellular phone? b = c. Fewer than 2 households have a cell phone? c = d. At least 6 households have a cellular phone? d = e. At least 1 household has a cellular phone? e =
Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7

A bird sanctuary has 14 bags of bird seed. Each bird feeder holds 1/6 of a bag. How many bird feeders can be filled with the bird seed?
Answer:
84 bird feeders can be filled
Step-by-step explanation:
Considering there is 14 bags, all you'd have to do is see how many bird feeders can be filled... and to do that, just multiply 14 x 6, because it every bag fills up 6 feeders. 14 x6 =84 bird feeders can be filled.
Hi guys I need your help here I'll give 100 points and also brainiest no link's please I need this by today thank you : )
Answer:
#2CD ║ EF and ED is transversal, hence
∠CDE ≅ ∠FED ⇒ m∠CDE = m∠FED ⇒ m∠CDE = 28° as alternate interior anglesm∠CDB = 160° - 28° = 132°We can see that:
m∠CDB + m∠ABD = 132° + 48° = 180°Since the angles CDB and ADB sum to 180, these are consecutive interior angles, therefore AB and CD are parallel lines.
#3PU and QT are parallel and PT is transversal, therefore:
∠UPT ≅ ∠QTP as alternate interior anglesm∠UPT = m∠QTP = 42° or x = 42°Now find the missing angles of ΔQTP
x + 40° = 42° + 40° = 82°y = 180° - (42° + 82°) = 56°Now, we see that:
m∠TPQ = 82°m∠SQR = 82°As ∠TPQ ≅ ∠SQR these angles are corresponding angles.
Therefore PT and SQ are parallel lines.

Answer: tangent
Step-by-step explanation: from the diagram the adjacent and the opposite are given. From SOHCAHTOA , tan is the only trig ratio with opposite and adjacent.
Thus tan teta= opposite÷adjacent
tan teta= 3÷6= 0.5
teta=tan invers of 0.5

What is division?
Division is a simple operation in which a number is divided. The splitting of a large group into smaller groups such that every group will have an equal number of items.
By using division concept, we can find the quotient when the divisor is divided by the dividend.
The divisor is 15048
The dividend is 76
Division is performed by using the division operator ÷
⇒ [tex]15048[/tex] ÷ [tex]76[/tex]
⇒ [tex]198[/tex]

4) Jerry cuts a piece of paper from one corner to the other, as shown. How long is the cut edge (look at photo)
A) 20 cm
B) 30 cm
C) 40 cm
D) 50 cm
Pls don’t put answer in a link
The required length of the cut edge will be 50 cm. which is the correct answer would be an option (D).
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
The piece of paper from one corner to the other, as shown figure.
Let the length of the cut edge would be x cm, which is equal to the hypotenuse in the given right triangle.
According to Pythagoras's theorem,
⇒ c² = a² + b² ....(i)
As per the given question, we have
c = x, a = 40 cm and b = 30
Substitute the values in the above formula, and solve for x
⇒ x² = 40² + 30²
⇒ x² = 1600 + 900
⇒ x² = 2500
⇒ x² = 50²
⇒ x = 50
Therefore, the required length of the cut edge will be 50 cm.

A shipping box is in the shape of a rectangular prism. It has a volume of 9,000 in.3, and the dimensions of the base are 20 in. by 30 in. What is the height of the box?
15 in.
20 in.
300 in.
600 in.
ITS NOT 20 I TOOK THE TEST AND GOT IT WRONG
Answer:
15 in.
Step-by-step explanation:
Volume of rectangular prism = length × width × height
Length = 30 in
Width = 20 in
Height = x
Volume of rectangular prism = 9000 in³
Volume of rectangular prism = length × width × height
9000 = 30 × 20 × x
9000 = 600x
x = 9000/600
x = 15 in
Answer:
15
Step-by-step explanation:
the formula of finding the volume of a rectangular prism is base times height. the base dimensions are 20*30 so its 600 square inches, 9000/600=15.
Find an equation of the line containing the points (1,4) and (3,18).
Answer:
y=7x-3
Step-by-step explanation:
(1,4). y=mx+b or 4=7 × 1+b, or solving for b: b=4-(7)(1). b=-3.
(3,18). y=mx+b or 18=7 × 3+b, or solving for b: b=18-(7)(3). b=-3.
hence, y=7x-3

Ray is late for work but would like to drink some coffee before he leaves. The coffee in the pot is too hot, so Ray puts 20 small ice cubes in a mug before pouring in the coffee. The ice cubes measure 1 cm per side. The mug is cylindrical and has a height of 9 cm and a base of 7 cm. What is the volume of the coffee that will fill the mug after the ice cubes have been added (round to the nearest whole number)?
A) 113 cm3.
B) 326 cm3.
C) 346 cm3.
D) 424 cm3.
Answer:
V,cube = sidelength^3
V,cube = (1 cm)^3
V,cube = 1 cm^3
Since there are 20 ice cubes, V = 20 cm^3
V,cylinder = pi * r^2 * h
V,cylinder = 3.14 * 3.5^2 * 9
V,cylinder = 346.185 cm^3
This is the volume of mug when full.
Since 20 cm^3 is allotted for the ice cube, thus,
346.185 - 20 = 326.185 cm^3
Yes it's B.

Answer:

Step-by-step explanation:
At the bottom of the shape, we can see the base is 60mm. The next side(left or right) is shown as 20mm. The next side right before the missing piece is 20mm. The width of the missing piece is 10mm. The length of the missing piece is 20mm because:
20 + 20 = 40
60mm - 40mm = 20mm
60mm + 20mm + 20mm + 10mm + 20mm + 10mm + 20mm + 20mm
180 mm

What value of x makes 6x + 5 equal to 12?
Answer:
x = 7/6
Step-by-step explanation:
6x+5 = 12
Subtract 5 from each side
6x+5-5 = 12-5
6x = 7
Divide each side by 6
6x/6 = 7/6
x = 7/6
Answer:
x=7/6
Step-by-step explanation:
6x+5 = 12
subract 5 from both sides
6x = 7
divide by 6 on both sides
x=7/6
