Answer:

∠A=125°

Step-by-step explanation:

Well since the lines are parallel, ∠B is opposite ∠A which means ∠B=∠A

[tex]4x+45=6x+5\\45=2x+5\\40=2x\\2x=40\\x=20[/tex]

x=20°

Plugging x into the equation for ∠A.

[tex]A=6*20+5\\A=120+5\\A=125[/tex]

∠A=125°

Answer:

x=20, m<a=125 degrees

Step-by-step explanation:

Angle A and B are going to be the same measure because of alternate interior angles. That means that 6x+5=4x+45

If you solve for x:

6x+5=4x+45

-5              -5

6x=4x+40

-4x -4x

2x=40

x=50. So, now we have figured out x. The question is asking for the exact measure of angle a. So, we just substitute with our x value.

6*20=120 and then we have to add 5. So, 125 degrees.

Answer:

(C)[tex]47.5^\circ[/tex]

Step-by-step explanation:

In the circle, the measure of arc ED is the measure of an angle subtended by arc ED at the centre.

Angle EFD on the other hand is an angle subtended by arc ED on the circumference.

We have a circle's theorem that states:

The angle subtended by the arc at the centre is twice the angle subtended by the same arc at the circumference, therefore:

[tex]m\angle ED=2 \times m\angle EFD\\95^\circ=2 \times m\angle EFD\\m\angle EFD=95 \div 2\\m\angle EFD=47.5^\circ[/tex]

Answer:

11

Step-by-step explanation:

Let's call the white marbles w and the red marbles r. We can write:

w + r = 16 (1)

w = 3r - 4 (2)

3r - 4 + r = 16 (3) (Substitute (2) into (1))

4r = 20 (simplify)

r = 5 (divide by 4) which means w = 16 - 5 = 11

Step-by-step explanation:

Done

Answer:

a. 0.69

b. 0.13

c.0.56

Step-by-step explanation:

Total number = 100

a) either means students with either option are valid

69/100 = 0.69

b) both means each student has done both math and english

=13/100 = 0.13

c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)

23+33=56

one subject =56/100 = 0.56

Answer:

D

Step-by-step explanation:

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

4 + 6 > 9

Yes, these lengths can form a triangle.

3 + 4 > 2

Yes, these lengths can form a triangle.

2 + 2 > 3

Yes, these lengths can form a triangle.

1 + 1 = 2

No, these lengths cannot form a triangle.

Answer:

D

Step-by-step explanation:

the formula is

a + b > c

a+ c > b

b+ c > a

The answer is D because

given lenght(D answer) A=1 , B=1, C=2

Thus, follow the formula.

a+b>c

1+1>2 ❌

a+c>b

1+2>1 ✅

b+c>a

Answer:

Step-by-step explanation:

The ceiling is in the shape of a square. If Its side lengths are 15 meters, then the area of the ceiling would be determined by applying the formula for finding the area of a square. It is expressed as

Area = length ²

Area of ceiling = 15² = 225 m²

Since each can of paint will cover 25 square meters, then the number of cans of paint needed to paint the ceiling is

225/25 = 9 cans

Answer:

8/17

Step-by-step explanation:

Here, we should know that the sine of an angle is the ratio of the opposite to the hypotenuse

So in this case, 15 is the opposite and 17 is the hypotenuse

To find the cos of same angle, it is the ratio of the adjacent to the hypotenuse

We need the adjacent side

We can use Pythagoras’ theorem here

It states that the square of the hypotenuse equals sum of the squares of the two other sides

let’s say the adjacent is f

17^2 = 15^2 + f^2

f^2 = 17^2 -15^2

f^2 = 64

f = √(64)

f = 8

So the Cos C would be adjacent/hypotenuse = 8/17

Answer:

y = 96°

Step-by-step explanation:

The measure of the inscribed angle y is half the measure of its intercepted arc.

The whole circle = 360°

the intercepted arc = 360° - 168° = 192°

Thus

y = [tex]\frac{1}{2}[/tex] × 192° = 96°

Step-by-step explanation:

this is a horizontal line so...

you need to keep the same y-values and find the average of the x-values

[tex]\frac{-2+10}{2} = \frac{8}{2} = 4[/tex]

this means that the x-coordinate is 4

and the y-coordinate is 3

have a good day

Answer:

Let the points be A and B

A(-2,3)---->(X1,y1)

B(10,3)---->(x2,y2)

Now,

Good luck on your assignment..

The expression that represents Michaela's balance at the end of the year is 5275{(1 + 0.081)⁴+(1 + 0.345)⁸}.

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for.

Given:

Michaela transferred a balance of $5275 to a new credit card at the beginning of the year.

The card offered an introductory APR of 8.1% for the first 4 months and a standard APR of 34.5% thereafter.

If the card compounds interest monthly,

then the expression that represents Michaela's balance at the end of the year,

= 5275{(1 + 0.081)⁴+(1 + 0.345)⁸}

Therefore, the expression is 5275{(1 + 0.081)⁴+(1 + 0.345)⁸}.

Answer:

Option (A)

Step-by-step explanation:

Parent function is given as G(x) = x²

If this function is reflected over the x-axis then the new function will be,

G'(x) = -x²

Then shifted 2 units right,

G"(x) = -(x - 2)²

Followed by the shifting of 1 unit down,

F(x) = -(x - 2)² - 1

Therefore, translated function of the given parent function will be,

F(x) = -(x - 2)² - 1  

Option (A) is the answer.

Answer:

Step-by-step explanation:

What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:

S = 3A + 7

Now we can sub in that value for S to the original equation:

If A + S = 111 and S = 3A + 7, then

A + 3A + 7 = 111 and

4A + 7 = 111 and

4A = 104 so

A = 26 and

S = 3(26) + 7 so

S = 85 miles.

Scott drove 85 miles.

Answer:

Scott drove 89.5 miles.

Step-by-step explanation:

Represent Andre's distance by a and Scott's by s.  Then s = 3a + 7.

Then the total distance driven by both is a + 3a + 7 = 117 (miles), or

4a - 110 miles, or a = 27.5 miles.  Thus, s = 3(27.5) + 7 = 89.5 miles.

Step-by-step explanation:

-23×-25=575

-25 should be multiplied by -23 to get 575

Answer:

-25

Explanation:

To solve this problem, let's start by creating an equation to help us find what number should be multiplied to negative twenty-three to get five hundred seventy five.

Let x represent the unknown number.

[tex]-23x=575[/tex]

Now, let's solve the equation. Divide both sides of the equation by negative twenty three.

[tex]-23x=575\\\\\displaystyle\frac{-23x}{-23} = \displaystyle\frac{575}{-23} \\\\ x = -25[/tex]

So, since the value of x is negative twenty five, the number that should be multiplied by negative twenty three to equal five hundred seventy five is -25.
