Cora is building towers of two different sizes using prism- and pyramid-shaped blocks. The diagram shows the ratio of prisms and pyramids in each tower. A tape diagram with 2 tapes of unequal lengths. The first tape has 4 equal parts. A curved bracket above the first tape is labeled Prisms. The second tape has 1 part of the same size as in the first tape. A curved bracket below the second tape is labeled Pyramids. A tape diagram with 2 tapes of unequal lengths. The first tape has 4 equal parts. A curved bracket above the first tape is labeled Prisms. The second tape has 1 part of the same size as in the first tape. A curved bracket below the second tape is labeled Pyramids. The table shows the number of prisms and the number of total blocks that Cora will use on each of her towers. Based on the ratio, complete the missing values in the table. Tower Prisms Total blocks AAA 161616 BBB 353535
Answer:
total blocks are 20 and prisms are 28
Step-by-step explanation:
There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B
From the tape diagrams, we have the following ratio
Prism : Pyramid = 4 : 1
From the table, we have:
Tower A = 16 prisms
So, the ratio becomes
16 : Pyramid = 4 : 1
Multiply the ratio on the right-side by 4
16 : Pyramid = 16 : 4
By comparison, we have:
Pyramid = 4
This means that, 4 pyramid blocks are needed for tower A
So, the total number of blocks needed is:
Total = Pyramid + Prism
This gives
Total = 4 + 16
Evaluate the sum
Total = 20
Hence, there are 20 blocks needed for tower A
For table B, we have:
Tower A = 35 prisms
So, the ratio becomes
35 : Pyramid = 4 : 1
Express as fractions
[tex]\frac{Pyramid}{35} = \frac 14[/tex]
Multiply through by 35
Pyramid = 8.75
This means that, 8.75 pyramid blocks are needed for tower B
So, the total number of blocks needed is:
Total = 8.75 + 35
Evaluate the sum
Total = 43.75
Hence, there are 43.75 blocks needed for tower B

Answer:
x = 2 and y = 3
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x
3x + 2(0) = 6
3x + 0 = 6
3x = 6 ( divide both sides by 3 )
x = 2 ← x- intercept
To find the y- intercept, let x = 0 in the equation and solve for y
3(0) + 2y = 6
0 + 2y = 6
2y = 6 ( divide both sides by 2 )
y = 3 ← y- intercept

Step-by-step explanation:
the total sugar bags to be distributed= x=48
the total rice bags to be distributed= y=72
each family can take a package containing= 1x +2y
as each family can have 2 rice bags thus we can estimate the total number of families that can benefit by diving total no of rice bags by 2 which will be = 72/2 =36
the rice can be divided into 36 families
while the sugar bags can be divided into 48 families
as these have to be divided into packages so there will be 36 packages
that can be distributed into 36 families.

2) area of one triangle is:

Consider the equation
2/3(12 – Ax) – 4 = 9(6 x + B).
What values for A and B will result in an equation that has infinite solutions?
Answer:
A = -81
B = 4/9
Step-by-step explanation:
An equation that has infinite solutions suggests that the left side equals the right side.
Expand brackets:
[tex]\dfrac23(12-Ax)-4 = 9(6 x + B)[/tex]
[tex]\implies 4-\dfrac23Ax = 54x+9B[/tex]
Equate coefficients of x:
[tex]\implies -\dfrac23A=54[/tex]
[tex]\implies A=-81[/tex]
Equate constants:
[tex]\implies 4=9B[/tex]
[tex]\implies B=\dfrac49[/tex]

see "additional comment" regarding listing pairs
Step-by-step explanation:
There are a number of ways angles can be identified as congruent. In each case, the converse of the proposition is also true.
opposite angles of a parallelogram are congruentcorresponding angles where a transversal crosses parallel lines are congruentalternate interior angles where a transversal crosses parallel lines are congruentvertical angles are congruentany two angles with the same measure are congruentIn these exercises, pairs of angles need to be examined to see which of these relations may apply.
__
ALeft
ABCD is a parallelogram, so the congruent angles are opposite angles and any that are vertical or corresponding:
∠BAC ≅ ∠BDC ≅ ∠EDF ≅ 110° (3 pairs)
∠ACD ≅ ∠ABD ≅ ∠BDE ≅ ∠CDF ≅ 70° (6 pairs)
Center
∠1 ≅ ∠4 ≅ 66° (1 pair) . . . . vertical angles
∠2 ≅ ∠3 ≅ ∠5 ≅ ∠6 ≅ 57° (6 pairs) . . . . marked with the same measure, and their vertical angles
Right
Assuming that lines appearing to go in the same direction actually do go in the same direction, the only pair of congruent angles in the figure is ...
∠2 ≅ ∠3
__
BLeft
Corresponding angles in congruent triangles are congruent. Here, the congruent triangles are ΔACD ≅ ΔCAB. So, the pairs of congruent angles are ...
∠ACD ≅ ∠CAB (30°)
∠CDA ≅ ∠ABC (90°)
∠DAC ≅ ∠BCA (60°)
Right
The corresponding angles and any vertical angles are congruent. This means all the odd-numbered angles in the figure are congruent, and all the even-numbered angles in the figure are congruent. The marked 72° angles show the "horizontal" segments are parallel by the converse of the corresponding angles theorem.
∠1 ≅ ∠3 ≅ ∠5 (72°) (3 pairs)
∠2 ≅ ∠4 ≅ ∠6 (108°) (3 pairs)
_____
Additional comment
The question asks you to list pairs of congruent angles. When 3 things are congruent, they can be arranged in 3 pairs:
a ≅ b ≅ c ⇒ (a≅b), (a≅c), (b≅c)
Similarly, when 4 things are congruent, they can be arranged in 6 pairs:
a ≅ b ≅ c ≅ d ⇒ (a≅b), (a≅c), (a≅d), (b≅c), (b≅d), (c≅d)
In the above, we have elected not to list all of the pairs, but to list the set of congruences from which pairs can be chosen.

A. ( x + 3 )² = 25
Step-by-step explanation:
2x² + 12x = 32
2(x² + 6x) = 32
x² + 6x + 9 = 16 + 9 [ addition of 9 from both sides ]
( x + 3 )² = 25
2. Which of the following represents the value of an investment with a principal of $1500 with a nominal interest
rate of 2.5% compounded monthly after 5 years?
(1) $1,697.11
(3) $4,178.22
(2) $1,699.50
(4) $5,168.71
Answer:
(2) $1,699.50
Step-by-step explanation:
A(t) = P(1 + r/n)^nt
1500(1 + .025/12)^5*12
= $1699.50
$1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.
What is compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
Given that an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years,
Amount = P(1+r/n)^nt
= 1500(1+0.25/12)^5*12
= $1699.50
Hence, $1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

A circle has an area of 2254 square inches. If the radius of the circle
is multiplied by 6, then what is the area of the new circle formed?
O A) 1000+ in.2
OB) 2270n in.

OD 81007 in.2
Answer:
Answer: OD 81007 in.2
Step-by-step explanation:
Use formula for area of circle, which is A = πr²
The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater. So the area is

What is the value of the indicated angle
127
37
180
53
Answer:
53
Step-by-step explanation:
It is either an alternate angle or an opposite angle of the 53 shown.
We know that angles on a straight line add up to 180, so:
53+x=180
x=180-53
x=127
We know that the indicated angle plus x would give 180, so:
?+x=180
?+127=180
?=180-127
?=53
