What is the total surface area of the right regular pyramid with a square base?
Answers
The lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Here,
Given is prism, we need to find the lateral surface and the total surface areas,
Lateral surface area = (perimeter of base) × length
Perimeter of base = 3 × 4 = 12 in
length = 8 in
The lateral surface area = 12 × 8 = 96 in²
Total surface area = (perimeter of base) × length × 2(base area)
= 96 × 2(3×4)
= 96 × 24
= 2304 in²
Hence, the lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.

Volume of the peanut butter is 3/4 c.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Here is given the method to measure the peanut butter.
Volume of the cold water at the beginning = 1 1/2 c
= 3/2 c
Volume of the water after adding the peanut butter = 2 1/4 c
= 9/4 c
Volume of peanut butter = 9/4 c - 3/2 c
= (9/4) - (6/4)
= 3/4 c
Hence the volume of the peanut butter is 3/4 c.

Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC
Answers
Answer:
EC/AB = FC/MA
Step-by-step explanation:
We are given AB
≅
BC that means that side AB and side BC are equal also we know that angle opposite to equalt
sides are equal.
Hence, ∠BAE=∠BCE-------(1)
Also ∠AEB=∠CEB.
Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:
60'=1°
30'=(1/2)°=0.5°
Hence ∠ABC = 130°30’=130+0.5=130.5°
Also we know that sum of all the angles in a triangle is equal to 180°.
Hence,
∠BAE+∠BCE+∠ABC=180°.
2∠BAE+130.5=180 (using equation (1))
2∠BAE=49.5
∠BAE=24.75° (DIVIDE BOTH SIDE BY 2)
Now in triangle ΔBEC we have:
∠BEC=90° , ∠BCE=24.75°
SO,
∠BEC+∠BCE+∠EBC=180°.
Hence, 90+24.75+∠EBC=180
∠EBC=180-(90+24.75)
∠EBC=65.25°
Now we are given AE = 10 in
Also ∠BEA= 90°.
And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.
\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)
similarly in right angled triangle ΔBEC we have:
\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)
Hence, using equation (2) in equation (3) we get:
EC=10 \text{in.}EC=10in.
Hence AC=AE+EC=10+10=20 in.
Hence side AC=20 in.
Angle 1 is in a triangle with angle 4 and a 53 degrees angle. What is the sum of the measures of those two angles?
Answers
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127
The value of angles are in given triangle as:
Angle 1 = 37°, angle 2 = 127°, angle 3 = 23°, and angle 4 = 90°.
Given that the triangle attached below.
Also given angle one with angle four and a 53° angle.
Since the sum all three angle of triangle is equal to 180°.
In triangle ABC,
∠A + ∠B + ∠C = 180
Angle 1 + 90 + 53 = 180
Angle 1 = 37°
Also the angle 4 is equal to 90°.
The angle 2 is equal to 127°, because 180 - 53 = 127°
Now, in triangle ACD,
∠C=127° and ∠D = 30
∠A + ∠C + ∠D = 180
Angle 3 + 127 + 30 = 23
Hence, the value of angles are:
Angle 1 = 37°
Angle 2 = 127°
Angle 3 = 23°
And angle 4 = 90°

5. Simplify
Answer:
t=2
Step-by-step explanation:
Simplify both sides of the equation.
16=4+3(t+2)
16=4+(3)(t)+(3)(2) (Distribute)
16=4+3t+6
16=(3t)+(4+6)(Combine Like Terms)
16=3t+10
16=3t+10
Step 2: Flip the equation.
3t+10=16
Step 3: Subtract 10 from both sides.
3t+10−10=16−10
3t=6
Step 4: Divide both sides by 3.

C
Step-by-step explanation:
initial amount: 12 7/8 lbs
ate: 0.75 lbs= 3/4 lbs = 6/8 lbs
used: 9 3/8 lbs
remainder: 12 7/8 - 9 3/8 - 6/8
= 3 1/8 - 3/8
