Answer:
Amount Robert will pay back = $434.04
Step-by-step explanation:
Formula for interest is;
I = (P * R * T)/100
We are given;
P = $390
Rate = 18%
Time; T = 229 days = 229/365
Thus;
I = (390 * 18 * (229/365))/100
I = $44.04
Thus, total amount Mario will pay back = $390 + $44.04 = $434.04

FIND THE MISSING LENGTH.
Answer:
x = 9
x+7 = 16
Step-by-step explanation:
The triangles in this geometry are similar, so the ratios of corresponding sides are proportional.
long side/short side = (x+7)/12 = 12/x
x(x +7) = 12²
x +7x -144 = 0 . . . . . subtract 144 to put in standard form
(x +16)(x -9) = 0 . . . . factor
x = 9 . . . . . . only the positive solution is useful here
The missing lengths are ...

This semicircle has a radius of 8cm . What is the area of this figure?
Answer:
100.48 cm² (Option 2)⠀
Step-by-step explanation:
⠀
We know,
[tex]{\longrightarrow \qquad \boldsymbol{\pmb{Area_{(semicircle)} = \dfrac{1}{2}( \pi {r}^{2} ) }}}[/tex]
⠀
Where,
r is the radius of the semicircle. Here, the radius is 8 cm .We will take the value of π as 3.14 .⠀
Now, Substituting the values in the formula :
⠀
[tex]{\longrightarrow \qquad \rm{{Area_{(semicircle)} = \it \dfrac{1}{2} \times 3.14 \times ({8})^{2} }}}[/tex]
[tex]{\longrightarrow \qquad \rm{{Area_{(semicircle)} = \it \dfrac{1}{ \cancel2} \times 3.14 \times \cancel{64} }}}[/tex]
⠀
[tex]{\longrightarrow \qquad \rm{{Area_{(semicircle)} = \it {1} \times 3.14 \times 32 }}}[/tex]
⠀
[tex]{\longrightarrow \qquad \rm{{Area_{(semicircle)} = \it {1} \times 100.48 }}}[/tex]
⠀
[tex]{\longrightarrow \qquad \boldsymbol{ \pmb{Area_{(semicircle)} \approx \it 100.48 }}}[/tex]
⠀
Therefore,
The area of the semicircle is 100.48 cm² approximately .Answer:
100.48 cm² ( option 2 )
Step-by-step explanation:
Given:-

A pencil has a mass of 25 grams of there are 8 pencils what is the total mass of all the pencils
Answer:
200g/0.2kg
Step-by-step explanation:
8 × 25g = 200g
The total mass of the pencil is 200 grams.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
A pencil has a mass of 25 grams.
there are 8 pencils.
Total number of pencils = 8
Mass of each pencil = 25 grams
Total mass of the pencils = 8 × 25 = 200 grams
Hence the total mass is 200 grams.

Write the standard equation of the circle with center (-10,-5) that passes through the point (-7.5)
The standard form of the equation of the circle is
(Type an equation. Simplify your answer.)
Answer:
(x +10)² +(y +5)² = 9
Step-by-step explanation:
The standard form equation for a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
The radius of your circle is the distance between the center and the given point. Those points lie on the same horizontal line, so the radius is the difference of their x-coordinates:
r = (-7) -(-10) = 3
The equation of the circle is ...
(x -(-10))² +(y -(-5))² = 3²
(x +10)² +(y +5)² = 9
geometry. find RN. pls help!!
Apply Thales theorem

[tex]\\ \rm\rightarrowtail \dfrac{10}{RN}=\dfrac{8}{5}[/tex]
[tex]\\ \rm\rightarrowtail 8RN=50[/tex]
[tex]\\ \rm\rightarrowtail RN=50/8[/tex]
[tex]\\ \rm\rightarrowtail RN=6.25[/tex]
Answer:
RN = 6.25
Step-by-step explanation:
Triangle Proportionality Theorem: If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.
Therefore,
MQ : MP = MR : MN
⇒ 8 : (8 + 5) = 10 : (10 + RN)
⇒ 8 : 13 = 10 : (10 + RN)
⇒ [tex]\sf\dfrac{8}{13}=\dfrac{10}{10+RN}[/tex]
Cross multiply and solve:
⇒ 8(10 + RN) = 10 × 13
⇒ 80 + 8RN = 130
⇒ 8RN = 130 - 80
⇒ 8RN = 50
⇒ RN = 50 ÷ 8
⇒ RN = 6.25

volume of triangular prism : area of base * Length
Given:
side of triangle : 4 cmside of triangle : 3 cmangle between 4 cm and 3 cm : 90°Length : 10 cmFind area of base:
[tex]\rightarrow \sf \dfrac{1}{2} * side \ 1 \ * side \ 2 \ * \ sin (\theta)[/tex]
[tex]\rightarrow \sf \dfrac{1}{2} *\ 4 \ * \ 3 \ * \ sin (90)[/tex]
[tex]\rightarrow \sf 6 \ cm^2[/tex]
Volume :
A * L6 * 1060 cm³Answer:
60 cm³
Step-by-step explanation:
To calculate the volume of the prism, we need to find the area of the triangle and multiply it by the height of the prism.
⇒ Volume of prism = Area of triangle × Height of prism
Find the area of the triangle
⇒ Volume of prism = (Area of triangle) × Height
⇒ Volume of prism = (1/2 × Base × Altitude) × Height of prism
⇒ Volume of prism = (1/2 × 3 × 4) × Height of prism
⇒ Volume of prism = (3 × 2) × Height of prism
⇒ Volume of prism = 6 × Height of prism
Substitute the height in the volume
⇒ Volume of prism = 6 × Height of prism
⇒ Volume of prism = 6 × 10
Solve for the volume.
⇒ Volume of prism = 6 × 10
⇒ Volume of prism = 60 cm³

Use the rectangle shown in the coordinate plane to answer each question.
1. Rotate rectangle KLMN 90º counter-clockwise about the origin. List the ordered pairs for each vertex of K'L'M'N'.
2. What do you notice about the ordered pairs of the original figure and the ordered pairs of the rotation about the origin?
Answer:
See below ↓
Step-by-step explanation:
1)
On rotating KLMN by 90° counterclockwise,the new coordinates are :K' = (-3, -6)L' = (-5, -4)M' = (-2, -1)N' = (0, -3)2)
What do we notice here?We notice that on rotating from Quadrant II to Quadrant III, we find that all the x and y values become negative (other than N' which changes intercepts from x to y)Answer:
Step-by-step explanation:
Rotate counter-clockwise = from right towards left
Rotate 90° about the origin = We can think that our rectangle is a flag and that we added a pole to it. The pole is rotated counter-clockwise about the origin until we have the 90°. Where is the flag now positioned?
(Draw a line from origin to one of the rectangle's points; draw another line from origin that is ⊥ to the previous one. You rotate that point 90° from right to left and will lend on the new line.)
1. K (-6, 3) L (-4, 5) M (-1, 2) N (-3, 0) → K' (-3,-6) L'(-5, -4) M'(-2, -1) N'(0, -3)
2. We notice that the rule for rotating 90° about the origin is (x, y)→(-y, x)

Allen was making trail mix, but he only wanted to make of the recipe. If the whole recipe called for of a cup of peanuts, how many cups will he need to make of the recipe? Choose the model that matches the situation.
It can be inferred that the amount of nuts that Allen requires depends on the amount of the recipe that he wants to make.
How many cups of nuts does Allen require to make the recipe?According to the information provided, one serving of the recipe calls for one cup of nuts. According to this, it can be inferred that to make a smaller or larger portion of the recipe, this amount must be divided or multiplied.
For example, if Allen calls for making two servings of the recipe, he would use two cups of nuts, while if he calls for making a half serving, he would use half a cup of nuts.
Note: The question is missing because there is some missing information. However I can answer it based on my general prior knowledge.
