Step-by-step explanation:

Answer:

y=x+1

Step-by-step explanation:

Slope intercept form is y=mx +b

m, the slope is 1. As the line goes up 1, it also goes right 1. 1/1 =1

b, the y intercept, intersects the y axis at 1 (0,1).

Therefore, the equation would be y=x+1

Step-by-step explanation:

Hey there!

Given figure is a triangular based prism. Where the triangle is right angled triangle.

So,

Hypotenuse (h) = 6.5m

Perpendicular (p) =2.5 m

Base (b) = 6m

Length of triangular prism (l) = 10m.

We have;

Lateral surface area= Perimeter*length of prism.

LSA = (6.5+2.5+6) * 10

LSA = 15*10

Therefore, LSA of the shape is 150 m².

Now, Area of base=( 1/2 )*b*p

= (1/2)*(6*2.5)

= 7.5 m²

Therefore, area of base = 7.5 m²

Now, TSA= 2*Area of base+LSA

= (2*7.5 + 150) m²

= 165 m²

Therefore, the Total surface area is 165 m².

Hope it helps....

Answer:

21/50

Step-by-step explanation:

Fraction that voted for team A = 7/10

Fraction of those that wear red cap = 3/5 of fraction of team A

Fraction of those that wear red cap = 3/5 of 7/10

Fraction of those that wear red cap = 3/5*7/10

Fraction of those that wear red cap = 21/50

Hence the fraction of people that wear red cap is 21/50

Answer:

Whitney = 6

Sara = 9

Hannah = 3

Step-by-step explanation:

Let :

Whitney = x

Sara = x + 3

Hannah = x / 2

Hannah's age + Whitney's age = Sarah's age

x / 2 + x = x + 3

1.5x = x + 3

1.5x - x = 3

0.5x = 3

x = 3/0.5

x = 6

Whitney = 6

Sara = x +3 = 6 + 3 = 9

Hannah = x/2 = 6/2 = 3

Answer:

6 laps

Step-by-step explanation:

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run

One tenth of a mile = 1/0

Three fifths of a mile = 3/5

From the question:

1/10 mile = 1 lap

3/5 mile = x

Cross Multiply

1/10 mile × x = 3/5 mile × 1 lap

x = 3/5 mile × 1 lap/ 1/10 mile

x = 3/5 ÷ 1/10

x = 3/5 × 10/1

x = 6 laps

Therefore, for there fifths of a mile(3/5) he needs to run 6 laps

Answer:

Char's monthly payment for the TV was $182.56.

Step-by-step explanation:

To find the answer, first you have to subtract the down payment from the cost of the TV:

$1,345.36-$250=$1,095.36

Then, you have to divide the remaining amount by six to find the monthly payment:

$1,095.36/6=$182.56

According to this, the answer is that Char's monthly payment for the TV was $182.56.

Answer:

Original cost =70 pounds

Step-by-step explanation:

Let original cost be x,

so original cost = x

[tex]x*\frac{80}{100} = 56[/tex]

[tex]x = 56 /\frac{80}{100}[/tex]

[tex]x = 70 pounds[/tex]

Answer: $3.04

Step-by-step explanation:

Brady bought 8 ounces of Skittles and it is said that one ounce costs $0.38.

His total cost will therefore be the quantity he bough multiplied by the cost of each quantity:

= Cost of an ounces of skittles * skittles bought

= 0.38 * 8

= $3.04

Brady had to pay $3.04.

Step-by-step explanation:

The factors common in both the given numbers are 2^3,3^2 and 5^2

Answer:21 cm

Step-by-step explanation: The circle's circumference is 84 cm. 84 / 4 = 21. Therefore the length of the arc XY is 21 cm.

The length of xy is 8.4 cm.

The correct option is A.

A circle's arc, or circumference, is a section of the circle. The difference between an arc length and an arc measure is the angle the arc creates with the circle's center. It is possible to measure this arc in radians or degrees.

If the circumference of Z is 84 cm, the radius can be calculated using the formula:

C = 2πr

where C is the circumference and r is the radius.

So,

84 = 2πr

r = 84/(2π)

r ≈ 13.369

Now, the length of xy (the minor arc) can be calculated using the formula:

length of arc = (central angle/360) x 2πr

To find the central angle, we can use the fact that the minor arc xy and the major arc AB add up to the circumference of the circle. Since the circumference is 84 cm, and the major arc AB has length equal to half the circumference, which is 42 cm, then the length of the minor arc xy is:

length of xy = 84 - 42 = 42 cm

Now, to find the central angle corresponding to this arc, we can use the formula:

central angle = (length of arc / 2πr) x 360

central angle = (42 / 2π(13.369)) x 360

central angle ≈ 57.051

Therefore, the length of xy is:

length of xy = (57.051/360) x 2π(13.369)

length of xy ≈ 8.455

Rounding to the nearest tenth, we get:

length of xy ≈ 8.4 cm

Therefore, the answer is option A, 8.4 cm.

Answer:

see explanation

Step-by-step explanation:

The angle at the centre of a circle is equal to the measure of the arc that subtends it, thus

AB = ∠ AOB = 49°

The measure of arc BC = 360° - (49 + 107)° = 360° - 156° = 204°, then

ABC = AB + BC = 49° + 204° = 253°

BAC = BA + AC = 49° + 107° = 156°

ACB = AC + CB = 107° + 204° = 311°
