So the Total balance to the bank is

25.62+45=$70.62

Answer:

49

Step-by-step explanation:

Complementary angles always add up to 90 degrees, so make and equation. First, say that angle ABC and angle QRS add up to ninety degrees. Substitute the values to get 41 degrees plus angle QRS equals 90 degrees, and once you subtract 41 from both sides, you get angle QRS equals 49 degrees.

Hope this helps. :)

The QRS is 49

We know that

The complementary angles are those whose sum is 90 degrees

So,

x + 41 = 90

x = 49

So, QRS = 49

Answer: 16

Step-by-step explanation:

From the question, we are informed that Nicole used 3/8 of her ribbon to wrap a present and that she used 6 feet of ribbon for the present,

To know how much ribbon did Nicole have at first goes thus:

Let the ribbon Nicole has at first be y

Since she used 3/8, this will be:

3/8 × y = 6

3y/8 = 6

Cross multiply

3y = 6 × 8

3y = 48

y = 48/3

y = 16

She had 16 ribbons at first

Answer:

A

Step-by-step explanation:

Looking at the interval, we can see that this includes all of the numbers coming from negative infinity all the way up to -1.

In other words, the set being described here are all the numbers less than or equal to -1.

Another way to write this is all numbers no more than -1.

Your answer is B

Step-by-step explanation:

Because if they are already $60 and she wants one more it would be $75

The cost for the 6th pajama bought by Keli is given as $85.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

The equation of the straight line from the given graph can be formed as below,

Take any two coordinates from the graph as (1, 10) and (2, 25) respectively.

Suppose the cost be y and the number of pajamas be x.

Now, the equation for the slope can be written as,

(y - 10)/(x - 1) = (25 - 10)/(2 - 1)

⇒ (y - 10)/(x - 1) = 15

⇒ y = 15x - 5.

Then, the cost of 6th pajama can be calculated by substituting x = 6 in the above equation as,

y = 15 × 6 - 5

  = 85

Hence, the cost of sixth pair of pajama is $85.

Answer:

A. To determine the value of a, set up and solve a system of equations in two variables. The value of a is 2

Step-by-step explanation:

Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;

M(X, Y) = (x₁+x₂/2, y₁+y₂/2)

X = x₁+x₂/2 and  Y = y₁+y₂/2

From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5

Substituting the given parameters into the formula, we can form up a simultaneous equation and get the value of a.

To determine the value of a, set up and solve a system of equations in two variables

For the X coordinates;

X = x₁+x₂/2

3 = b+1+2a/2

6 = 2a+b+1

2a+b = 5 ............... 1  * 1

For the Y coordinates;

5 = a+2+3b+3/2

cross multiply

10 =  a+2+3b+3

collect like terms

a+3b = 10-2-3

a+3b = 5 ........ 2  * 2

Solving the resulting  simultaneous equation to get the value of a

multiply equation 1 by 1 and 2 by 2 to have the resulting equations;

2a+b = 5 ...........3  

2a +6b = 10.......... 4

subtract 3 from 4

(2a-2a)+(b - 6b) = 5-10

0-5b = -5

b = -5/-5

b = 1

substitute b =1 into equation 1 to get a;

2a + b = 5

2a + 1 = 5

2a = 5-1

2a = 4

a = 2

From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2

Answer:

Step-by-step explanation:

Given the following lengths AB = 64, AM = 4x + 4 and BM= 6x-10, If M lies on the line AB  then AM+MB = AB (addition property)

Substituting the given parameters into the addition property above;

AM+MB = AB

4x + 4 + 6x - 10 = 64

combine like terms

4x+6x = 64+10-4

10x = 74-4

10x = 70

Divide both sides by 10

x = 70/10

x = 7

Note that for M to be the midpoint of AB then AM must be equal to BM i.e AM = BM

To get AM ;

Since AM = 4x+4

substitute x = 7 into the function

AM = 4(7)+4

AM = 28+4

AM = 32

Similarly, BM = 6x-10

BM = 6(7)-10

BM = 42-10

BM = 32

Since AM = BM = 32,. then M is the midpoint of AB

Answer:

The line that can be drawn through points D and E is contained in plane Y.

Step-by-step explanation:

Let's just go through all of these answer choices.

The first one says that "The line that can be drawn through points C and D is contained in plane Y." Is this true? If we drew a line connecting points C and D, it looks like it would cross through both planes X and Y, so it cannot be contained in only plane Y. This is false.

The second one says that "The line that can be drawn through points D and E is contained in plane Y." If we imagine a straight line going from point D to point E, it looks like it's just a line in plane Y; so this can be contained in plane Y. This seems true.

The third one says that "The only point that can lie in plane X is point F." This is false because plane X has a ton of points, but point F is just the only one that's labeled. This is false

The fourth one is similar, and says that "The only points that can lie in plane Y are points D and E." Again, this is false because points D and E just happen to be the only two labeled points, but there are infinitely many points on plane Y; points D and E are not all of them.

The second answer choice is true.

Answer:

D. 3:5 and E. 15:25

Step-by-step explanation:

If it is 60%, it means that the ratio is 6:10 (60/100).

Because both 6 and 10 are divisible by 2, we can then simplify the ratio to 3:5.

Therefore it is D. 3:5

We can then multiply both sides by 5 which will give us 15:25, so E is also correct.

The others of not correct because they are not equivalent to the ratio 3:5.

Answer:

20 rabbits, 10 chickens

Step-by-step explanation:

Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.

Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.

So the extra (100 – 60) = 40 legs must have come from the rabbits.

Every rabbit has (4 – 2) = 2 more legs than a chicken.

So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.

Answer:

20 rabbits and 10 chicks

Answer:

2 m/s

Step-by-step explanation:

Since speed is total distance over time, we first need to find the total distance the car traveled.

Total distance = 200 + 80 + 120 = 400 m

total time = 200 sec

speed = distance/time = 400/200 = 2 m/s

Apply inverse law

a a⁻¹ = 1

The solution of the given linear equation is x = -6

Step-by-step explanation:

Step(i):-

Given equation -3 x-5=13

Adding '5' on both sides, we get

- 3 x - 5 + 5 = 13  + 5

- 3 x  = 1 8

step(ii):-

apply inverse law

a a⁻¹ = 1

(- 3)(-3)⁻¹ x = 18 (-3)⁻¹

x = 18/-3 = -6

(or)

Dividing '-3' on both sides , we get

                            [tex]\frac{-3 x}{ -3} = \frac{18}{-3}[/tex]

                             x =- 6

Answer:

25π/6 yd

Step-by-step explanation:

∠DCE = 110°, so arc DFE = 360° − 110° = 250°.

In radians, that's 250° × π/180° = 25π/18.

Arc length is:

s = rθ

s = (3 yd) (25π/18)

s = 25π/6 yd

Step-by-step explanation:

Correct question is;

The medical thermometer commonly used in homes can be read +/-0.1 °F, whereas those in the doctor's office may be accurate to +/- 0.1 C in degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9 °C

Answer:

A) percent error in homes = 0.144 %

B) percent error in doctors office = 0.257 %

Step-by-step explanation:

A) Temperature is 38.9° C

Converting to Fahrenheit using the formula; (°C × 9/5) + 32

So;

(38.9°C × 9/5) + 32 = 102.02 °F

Since thermometer in homes can be read to +/-0.1 °F, then

Expected values = 102.02 +/- 0.1 = 102.12 °F or 101.92 °F

Since we want to find the error from °C, let's convert to °C.

We will use 101.92 °F.

Thus; 102.12 °F = (101.92 - 32) × 5/9 = 38.844 °C

Thus percent error = (38.9 - 38.844)/38.9) × 100% = 0.144 %

B) Temperature is 38.9 °C

Since thermometer in Doctors office can be +/- 0.1 °C, then;

Expected values = 38.9 +/- 0.1 = 38.8 °C or 39 °C.

We will use 38.8°C

Thus;

percent error = (38.9 - 38.8)/38.9) × 100% = 0.257 %
