Find the area of the isosceles triangle.
13 cm side
10 cm base

Answer:

22

Step-by-step explanation:

The four-year-old brother can arrange the Legos in rows of 8.

To find the least number of rows the four-year-old brother can make with the black and yellow Legos, we need to determine the greatest common divisor (GCD) of 56 and 120. The GCD will represent the number of Legos in each row.

To find the GCD, we can use the Euclidean algorithm. Divide the larger number (120) by the smaller number (56). The remainder is 8. Then, divide the smaller number (56) by the remainder (8). The new remainder is 0.

Therefore, the GCD of 56 and 120 is 8. This means that the four-year-old brother can arrange the Legos in rows of 8, with 7 rows of black Legos and 1 row of yellow Legos, or vice versa.

Answer:

Circumference = 3.14 diameter     C = 3.14(6)     Answer: 18.84  

Step-by-step explanation:

The equation for circle at A is (x+4)²+(y+2)²=9 whose radius is 3 units.

The equation of the circle is (x-h)²+(y-k)²=r²

Where h and k are the coordinates of centre of circle and r is radius of the circle.

From the given figure (h, k) is (-4, -2) and r is 3 units

Plug in these values in the equation of circle.

(x-(-4))²+(y-(-2))²=3²

(x+4)²+(y+2)²=9

Hence, the equation for circle at centre A is (x+4)²+(y+2)²=9 whose radius is 3 units.

Answer:

13/7 =n

Step-by-step explanation:

1/2(2n+4)+6=-9+4(2n+1)

Distribute

n +2 +6 = -9 + 8n +4

Combine like terms

n +8 = 8n -5

Subtract n from each side

n+8-n = 8n-n-5

8 = 7n-5

Add 5 to each side

8+5 = 7n-5+5

13 =7n

Divide each side by 7

13/7 = 7n/7

13/7 =n

Answer:  n = 13/7 = 1.857

Answer:

x-6

Step-by-step explanation:

The formula for the area of a rectangle is (l)(w)

x-5(w)=x²-11x+30

To solve, you need to put the quadratic equation into standard form

x-5(w)=(x-5)(x-6)

Divide both sides of the equation by x-5 to isolate the width(basically strike out x-5 on both sides)

the width is x-6

I pretty sure that's the right answer since (x-5)(x-6)=x²-11x+30, but I'm in geometry right now, and I had to go back and re-learn.

The surface area of the cylinder is 16.125π cm², which is closest to option D) 19.55π cm².

To find the surface area of a cylinder, we need to calculate the sum of the areas of its two bases and its lateral surface.

The formula for the lateral surface area of a cylinder is given by:

[tex]\[ LSA = 2 \pi r h \][/tex]

where [tex]\( r \)[/tex] is the radius and [tex]\( h \)[/tex] is the height of the cylinder.

Given that the diameter of the cylinder is 1.5 centimeters, the radius [tex]\( r \)[/tex] is half of that, which is [tex]\( \frac{1.5}{2} = 0.75 \)[/tex] centimeters.

The height of the cylinder is given as 5 centimeters.

Substituting these values into the formula for the lateral surface area:

[tex]\[ LSA = 2 \pi (0.75) (5) \][/tex]

[tex]\[ LSA = 15 \pi \][/tex]

Now, we need to find the area of the two bases of the cylinder. Since the cylinder has two circular bases, we can find their combined area using the formula for the area of a circle:

[tex]\[ A_{\text{base}} = \pi r^2 \][/tex]

[tex]\[ A_{\text{base}} = \pi r^2 \][/tex]

[tex]\[ A_{\text{base}} = \pi (0.75)^2 \][/tex]

[tex]\[ A_{\text{base}} = \pi (0.5625) \][/tex]

[tex]\[ A_{\text{base}} = 0.5625 \pi \][/tex]

The total surface area is the sum of the lateral surface area and the areas of the two bases:

[tex]\[ \text{Total Surface Area} = LSA + 2A_{\text{base}} \][/tex]

[tex]\[ \text{Total Surface Area} = 15 \pi + 2(0.5625 \pi) \][/tex]

[tex]\[ \text{Total Surface Area} = 15 \pi + 1.125 \pi \][/tex]

[tex]\[ \text{Total Surface Area} = 16.125 \pi \][/tex]

[tex]\[ \text{Total Surface Area} = 16.125 \pi \][/tex]

Therefore, the surface area of the cylinder is 16.125π cm².

The closest option is D) 19.55π cm².

The common difference of the arithmetic sequence 1, 201, 401, 601, ... is 200, which is the difference between successive pairs of terms.

In Mathematics, the common difference in an arithmetic sequence is the amount by which successive terms increase. In the given series: 1, 201, 401, 601, ..., the common difference can be found by subtracting a term from the term after it. For instance, if we subtract 1 (the first term) from 201 (the second term), we get 200. If we do the same for 201 and 401 (the second and third terms), we also get 200. This means that the common difference for this arithmetic sequence is 200.

△ABC  right angle C, leg BC > leg AC.  So angle A > angle B.

a=BC, b=AC, c=AB

a > b

sin A= cos B = a/c

sin B = cos A = b/c

a = c sin A = c cos B

b = c sin B = c cos A

a > b

c sin A > c sin B

sin A > sin B

c cos B > c cos A

cos B > cos A

Answer:  B, E

Final answer:

In a right-angled triangle △ABC with BC > AC, it is true that m∠B > m∠A, sin A < sin B, and cos A > cos B. These correspond to choices A, C, and D.

Explanation:

In the context of triangle △ABC where angle C is a right angle and BC > AC, we can assess the truth of various statements regarding the angles and their sine and cosine values:

m∠B > m∠A: This statement is true because in a right-angled triangle the side opposite the right angle is the hypotenuse and is the largest side. Therefore, the angle opposite the longest side (BC) must be the largest acute angle, hence m∠B > m∠A.

sin A > sin B: This statement is false. Since m∠B > m∠A and sine of an angle increases with the angle's magnitude (for acute angles), it must be that sin A < sin B.

sin A < sin B: This statement is true based on the relationship of the sides and angles mentioned earlier.

cos A > cos B: This statement is true. Since m∠B > m∠A and cosine of an angle decreases as the angle's magnitude increases (for acute angles), it must be that cos A > cos B.

cos A < cos B: This statement is false for the same reason that cos A > cos B is true.

The correct statements are therefore A, C, and D.

Step-by-step explanation:

Number of even numbers on a die-3

Number of odd numbers on a die-3

a die has 6 sides,

therefore

1/2 of the numbers on a die are even and 1/2 are odd

so a 3/6 chance (1/2 chance (simplify)) of landing on an even number on the first roll

And  a 3/6 chance (1/2 chance (simplify)) of landing on an odd number on the second roll

Multiply the two together and a 9/36 chance of this event or simplified to a 1/4 chance of this event

Answer:

if the probability of a 6 is 1/5, the probability of “not six” is 4/5. The probability of a 6 on the first roll and not on the second is 1/5 x 4/5 = 4/25. The six could come on the second roll so that probability must be doubled. The overall probability of exactly one six is 8/25 or 0.32.

Step-by-step explanation:

The translation that maps ABCD onto A’B’C’D’ is Right 6, down 5.

Translation on the coordinate plane is sliding a point or figure in any direction without any changes in size or shape.

In fact, during translation, the coordinates of the vertices of a figure or point change, and they slide left or right, up, or down without changing size or shape.

The translation that maps ABCD onto A’B’C’D’ is;

Shift ABCD to the right side by 6 units then shifted down by 5 units to get A'B'C'D'.

ABCD moved ( 6 units ) times to the ( right), and ( 5 units ) times to the ( bottom) to convert into A'B'C'D'.

Hence,  the translation that maps ABCD onto A’B’C’D’ is Right 6, down 5.

Answer:

1. C.

2. B.

3. A.

Step-by-step explanation:

First situation given:

An adult and 5 children rent skates. It costs $ 4 per adult for skates and a total of $ 16.

Correct equation: C

4 + 5 x = 16

Second situation given:

It costs Mikael $ 4 to make a bike bag, and he sells each for $ 5. He has made a profit of $ 16, so far.

Correct equation: B

( 5 − 4 ) x = 16

Third situation given:

It was 16°C. It began falling 4°C per hour until it reached 5°C.

Correct equation: A

16 − 4 x = 5

Equations are matched to situations based on the context provided: the adult and children renting skates is described by 4 + 5x = 16, Mikael's profit from selling bike bags fits the equation (5 - 4)x = 16, and the temperature dropping over time corresponds to 16 - 4x = 5.

To match each equation to its corresponding situation, let us consider each situation and then associate the relevant equation.

Adult and children renting skates: An adult rents skates at $4, and the total cost including 5 children is $16. The equation representing the total cost is the adult's cost plus 5 times the children's cost equals $16, which is: 4 + 5x = 16.

Mikael making a profit from bike bags: Mikael spends $4 to make a bike bag, sells it for $5, and has made a profit of $16. To determine how many bags he sold (x), we can use the equation that accounts for profit, which is the selling price minus the cost of making the bag, multiplied by the number of bags, equals the profit: (5 - 4)x = 16.

Temperature drop: The temperature started at 16°C and dropped at a rate of 4°C per hour until it reached 5°C. To find the number of hours (x) it took for the temperature to drop, we can use the equation that links the initial temperature, minus the drop per hour times the number of hours, equals the final temperature: 16 - 4x = 5.

Now, we can clearly match the equations to their situations:

The situation where an adult and children rent skates corresponds to the equation 4 + 5x = 16.

Mikael making a profit from selling bike bags is represented by the equation (5 - 4)x = 16.

The decrease in temperature over time until it reached 5°C is described by the equation 16 - 4x = 5.
