Answer 1

Answer:

C: x=-10

Step-by-step explanation:

Alternate interior angles are congruent to each other meaning that x+80=70 making x equal to -10. I hope this helped and this is one of my favorite units so post more these questions :)

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 10 cm long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the bookmark? Use 3.14 for π.

The area of the bookmark is cm2.

Plzz help me

Answers

Answer:

Area of the bookmark = 52.56 cm²

Step-by-step explanation:

The two semicircles attached at both end of the rectangle will give us a full circle.

Therefore,

Area of the bookmark = area of rectangle + Area of a circle

Area of the bookmark = L × W + πr²

Length (L) = 10 cm

Width (W) = 4 cm

radius (r) = ½(4) = 2 cm

π = 3.14

Plug in the values into the equation

Area of bookmark = 10 × 4 + 3.14 × 2²

= 40 + 12.56

= 52.56 cm²

What is a reasonable estimate for the area of a circle with radius 4cm?

X = -1

This is because when you multiply 2 to the -1 power, it is negative because a positive times a negative is always negative. And 1/2 by the same -1 is -1/2

The is is -1 because for f(x) 2^-1 is .5 then subtract 1 from that is -.5 and for g(x) 1/2(-1) = -.5

is the point (2,5) a solution to the equation y=3x-5?

Answers

Answer and Step-by-step explanation:

To figure out, we plug in the x-value into the equation and see if it is equal to the y-value.

y = 3(2) - 5

y = 6 - 5

y = 1

5 ≠ 1

The point (2, 5) is not a solution.

Answer:

Step-by-step explanation:

From the given scatter plot, it is positive correlation.

What is scatter plot?

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

Interpretation of correlation

A scatter plot with increasing values of both variables can be said to have a positive correlation. A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation.

From the given graph,

The coordinates points are in increasing order.

Therefore, the correlation is positive.

Karim had a packet of 200 chocolates. He gave 35% of them to his sister. How many chocolates were left with him?

Answers

Answer:

Karim had 130 chocolates left.

Step-by-step explanation:

The quick way to do this is to notice that if he gave away 35% of his chocolates, he must have 65% left. That comes about by doing

100% (which is what he started with) - 35% = 65%

65% of 200 Change 65% into a fraction

65/100 * 200 Multiply 200 * 65

13000 / 100 Divide by 100

130

Answer:

130 left

Step-by-step explanation:

35% of 200 chocolates is equal to 70 chocolates.

200-70=130 chocolates

Find the x-intercept and the y-intercept of the graph equation 7x +3y =21 type a integer

Answers

Answer:

7(y intercept)

Step-by-step explanation:

y = mx +c form

y = 21-7x/3

c = 21/3 = 7(y intercept)

x i have no idea

To find x-intercept ,put y= 0 in the given eqn

So, 7x+3(0) = 21

=> 7x =21

=> x= 21/7 = 3

x-intercept = 3

Similarly, to find y-intercept put x=0 in the given eqn

So ,7(0)+3y=21

=> 3y=21

=> y= 21/3 = 7

y-intercept = 7

Answer:

a) ADC

b) ABC

c) ACB

d) CAD, DAB

e) CDm, BDA

f) ABD

Step-by-step explanation:

a) Any of the letters on lines going through point D could be used to name an angle with DC as one side. (Letters s and C would name an angle of measure zero, so might not be of interest.)

∠ADC has side DC

b) Any angle name with B in the middle will have B as its vertex.

∠ABD is an angle with vertex B

c) Ray CE is coincident with ray CD, so ...

∠ACE is another name for ∠ACD

d) Adjacent angles share a side, typically between the two angles. A linear pair of angles will be adjacent angles.

∠BAD and ∠CAD are adjacent angles

e) In order to properly name a pair of vertical angles, we need to be able to name two sets of opposite rays that share end points. Opposite rays emanate from points C and D, but no named points are seen outboard of those intersections. If we use 'm' as the name of a point on line m, then we can say a pair of vertical angles is ...

CDm and BDA are two vertically opposite angles

f) The supplement to EBD will be the other angle that makes a linear pair with angle EBD. It is defined using point A on the ray opposite ray BE.

∠ABD is the supplement of ∠EBD

Jada should use the tank of golf balls

Step-by-step explanation:

Jada should choose the tank that has a higher probability of choosing a ball with even number from.

Tank of tennis balls has two even numbers out of the ten balls (2, 4)

Tank of golf balls has seven even numbers out of the ten balls.

Tank of golf balls would give Jada more chance to pick an even number to win the game

Therefore, Jada should use the tank of golf balls

Answer:

n = 20/7
