What is the sum of the measures that represent the measures of each angle if m∠ABC=2x°, m∠CBD=3x°, and m∠EBD=4x°?
What is the measure of each angle?
Explain how an equation can be written to find m∠CBD.
Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
Plug the answer back in
The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees, and the other two angles are equal, what is the measure of each of the other two angles? Choose the equation that represents the situation. Let "a" represent the unknown angle measurement.
A. 2 + a + 45 = 180
B. 2a + 45 = 180
C. 45a + 2 = 180
Answer:
B
Step-by-step explanation:
2a+45=180
subtract 45 from both sides which equals 2a=135
divide both sides by 2 which would solve for a.

5 calculators cost $140.00
Answer:
The cost of 1 calculator is $28.00
Step-by-step explanation:
You haven't mentioned the question. Anyways if you want to find the value of 1 calculator, the simplest method ( in my opinion) you could do so in the ratio method:
5 calculators : $140
1 calculators : x
( x is the cost of 1 calculator. You have to find x. )
Cross multiply both the ratios. Multiply 5 with x and 140 with 1.
5x = 140 × 1
5x = 140
Bring 5 to the other makes 140 divided upon 5, as it was multiplied with x.
x = [tex]\frac{140}{5}[/tex]
x = $28
You could not only find the cost of 1 calculator, but any number of calculators. Just replace the number of calculators with 1 calculator that I have found the cost of.

What is (-3,0) be 90 degrees clockwise on a graph?
Answer:
(0, 3)
Step-by-step explanation:
Visualize this problem as being based on a circle of radius 3. (-3, 0) lies on this circle, straddling the x-axis.
Now if we rotate that radius (connecting the (0, 0) to (-3, 0) clockwise, the point (-3, 0) becomes the point (0, 3).

Choose the correct number line that represents the following inequality...
x>5
Answer:
The third one.
Step-by-step explanation:
On a number line, the circle would be on 5 with an open circle (because 5 is not included in the inequality) and the arrow would go to the right. The right arrow includes all values greater than 5.
Hope this helps.
Answer:
it is the one you picked
Step-by-step explanation:
When it is a greater or less than sign, it will be a opened circle whereas when it is a closed circle, it is a greater than/ less than or equal to.

Savannah uses models to compare two decimal numbers. She says 0.35 is greater than 0.4 because 35 > 4.Which of these explains Savannah's mistake?
Question 8 options:
Savannah incorrectly compared hundredths to tenths. She should compare 35 hundredths to 40 hundredths.
Savannah incorrectly compared tenths. She should compare 3 hundredths to 5 hundredths.
Savannah incorrectly shaded the models. She should shade one more tenth.
Savannah incorrectly counted the number of shaded parts in the models. She should compare 3 shaded parts to 4 shaded parts.

Please answer the following essay question:
Suppose each dimension of a cube is increased. What happens to the surface area when each dimension is doubled, tripled or, quadrupled?
Answer:
Step-by-step explanation:
Surface area of a cube = 6a²
When each dimension is doubled, Side =2a
Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)
So, when each dimension is doubled, surface area is 4 times of the original surface.
a = 3a
Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²
= 9 times the original area
a = 4a
Surface area = 6*(4a)² = 6* 16 * a²
= 16 * (6a²)
= 16 times of original area

The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the perimeter of the rectangle.
Answer:
5 ft and 11 ft
Step-by-step explanation:
l= 2w+1
A=lw= 55
w(2w+1)=55
2w²+w-55=0
integer solution of quadratic equation is:
w=5 ft
l= 2*5+1=11 ft
Answer:
32 feet
Step-by-step explanation:
Start by creating your 2 equations
l = 2w + 1
l * w = 55
Plug in l, the isolated variable
(1 + 2w)w = 55
w + 2w² = 55
2w² + w -55 = 0
( − 5 ) ( 2 + 1 1 ) = 0
w= 5
w= -11/2 <- the width can't be negative so this one is out
Plug width into the area formula to find length
l * 5 = 55
l = 11
Find the Perimeter
2(11) + 2(5)
22 + 10 = 32

PLz help me
Answer:
1,960
Step-by-step explanation:
35 times 56 = 1,960
35 is the base, to get the base you do length times width.
the height is 56. To get the volume do base (or length times width) times hight.
