Answer:
[tex] x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}[/tex]
Step-by-step explanation:
This kinda Questions can be easily done using the Quadratic formula or Shreedhacharya's Formula . Which is used to find the roots of a quadratic equation in Standard form of ax² + bx +c = 0 .
Wrt . Standard form ,
[tex]\implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\implies x = \dfrac{-3\pm \sqrt{3^2-4(1)(5)}}{2(1)}\\\\\implies x = \dfrac{-3\pm \sqrt{9+20}}{2} \\\\\implies \boxed{\boxed{ x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}}}[/tex]

Athena deposits $500 into a savings account that earns 5.4% simple interest.
Number of periods= 3 years
To calculate the interest earned, we need to use the following formula:
I= P*r*t
P= principal
t= number of periods
I= 500*0.054*3
I= $81
Which equation is the inverse of y = 100 - x??
y=/100-X
y = 10+ x
ay = 100+ /

Answer:
9
Step-by-step explanation:
The given two triangles must be similar by AA similarity Condition . Therefore ,
∆EDA ~ ∆ CBA .And the corresponding sides of the similar triangles are Proportional . Therefore ,
⇒ ED/ CB = AD/AB
⇒ 11/2 = 3 + x / 3
⇒ 33 = 2(3+x)
⇒ 6 + 3x = 33
⇒3x = 33 - 6
⇒ 3x = 27
⇒ x = 27/3
⇒ x = 9
Hence the value of x is 9 .complete the table below to identify the pattern. Find the maximum
Answer:
[tex]y = 200 + 45x \\ so \: when \: x = - 3 \\ y = 65.......... \\ at \: x = 1 \\ y = 245 \\at \: x = 2 \\ y = 290 \\at \: x = 3 \\ y = 335[/tex]
Find the surface area of the figure below.
Answer:
696.8 mm^2
Step-by-step explanation:
Well first lets find the bottom part of the square first.
13*13= 169
Thats the floor
13*5= 65
Thats 1 of the sides
there are 4 sides
65*4= 260
260+169= 429
Now find the triangle
(13*10.3) / 2
You’d get 66.95
66.95 *4 since there are 4 sides
You’d get 267.80
267.8+429= 696.8

Find the measure of the indicated arc
Step-by-step explanation:
We know that if an arc subtends an angle of theta , with a radius r , then the measure of arc is r× theta . Here theta is 109° .
[tex]\implies l = r\theta \\\\\implies l = r\times 109^{\circ}\\\\\implies l = r \times \dfrac{109}{180}\pi rad \\\\\implies \boxed{\boxed{ l = 0.6\pi r m }}[/tex]
where r will be the radius .

Step-by-step explanation:
1. Find the area of the green block
Area = L x W x H
1/3 *1*1 = 1/3
2. Find the area of the blue block
1*1*1 =1
3.) Divide the blue area by the green area
1 ÷ [tex]\frac{1}{3}[/tex] = 3
Check : 1/3 + 1/3 + 1/3 = 3/3 3/3 = 1
3 green blocks can fit into 1 blue block

Answer: 6.7
Step-by-step explanation:
An angle measures 32° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
First angle = x
Second angle = x - 32
We know that, complementary angles form => 90°
So,
[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]
First angle,
=> x = 61°
Second angle
[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]
Second angle,
=> 29°

Can I have brainllest
pleas e help !?!?!!j
Answer:
see explanation
Step-by-step explanation:
step 2 : 4x + 4 - 2x = - 6x + 6 + 14
Simplify both sides by collecting like terms ← what was done
step 3 : 2x + 4 = - 6x + 20
------------------------------------------
step 4 : 8x + 4 = 20
Subtract 4 from both sides ← what was done
8x = 16
Concept 10.3: Find the area of the shaded sector. Round to the nearest tenth.
Answer:
c
Step-by-step explanation:
Step-by-step explanation:
Here's your solution
=> area of circle = πr^2
,=> area = (22/7)*6*6
=> area = 113.04 insq
=> area of sector =( πr^2*8°)/360°
=> area of sector = 2.51 insq
=> area of shaded region = 113.04 - 2.51
=> area = 110.53 in.sq

Samantha and her children went into a grocery store and she bought $7 worth of bananas and peaches. Each banana costs $0.40 and each peach costs $0.50. She bought a total of 15 bananas and peaches altogether. Determine the number of bananas and the number of peaches that Samantha bought.
Answer:
Ten Peaches and five bananas.
Step-by-step explanation
To solve the problem increase the cost by adding more peaches and less by adding more bananas
7 peaches = 3.50
8 bananas = 3.20 + 3.50 = 6.70
We need 30 more cents so add three more peaches
10 peaches = 5
5 x 0.4 = 2
2 + 5 = 7
