The value of x when h (x) = 3 would be -1.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given a function of x as;
h(x)=2x+5
We need to find the value of x when h (x) = 3
Thus,h(x)=2x+5
Plug the value;
3=2x+5
Remove 5;
3-5=2x
-2=2x
So, x = -2 /2
x= -1
Hence, the value of x when h (x) = 3 would be -1.

Assume that the SAT scores are normally distributed. What is the probability that a randomly selected high school senior's score on mathe- matics part of SAT will be
(a) more than 675?
b) between 450 and 675?
Answer:
The probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514
Step-by-step explanation:
Mean of Sat =[tex]\mu = 500[/tex]
Standard deviation = [tex]\sigma = 100[/tex]
We will use z score over here
What is the probability that a randomly selected high school senior's score on mathe- matics part of SAT will be
(a) more than 675?
P(X>675)
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{675-500}{100}[/tex]
Z=1.75
P(X>675)=1-P(X<675)=1-0.9599=0.0401
b)between 450 and 675?
P(450<X<675)
At x = 675
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{675-500}{100}[/tex]
Z=1.75
At x = 450
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{450-500}{100}[/tex]
Z=-0.5
P(450<X<675)=0.9599-0.3085=0.6514
Hence the probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514

Triangle Similarity Day 4- Overlapping triangles
Solve for x. Remember to draw two triangles and set up the proportion.
Answer:
x = 16
Step-by-step explanation:
The two ∆s would be ∆ABC and ∆EFG as drawn in the attachment below.
Thus, ∆ABC ~ ∆EFG. Therefore:
[tex] \frac{AB}{EF} = \frac{AC}{EG} [/tex]
AB = 12 + 3 = 15
EF = 12
AC = x + 4
EG = x
Plug in the values into the equation
[tex] \frac{15}{12} = \frac{x + 4}{x} [/tex]
Cross multiply
[tex] (15)(x) = (x + 4)(12) [/tex]
[tex] 15x = 12x + 48 [/tex]
Subtract 12x from each side
[tex] 15x - 12x = 48 [/tex]
[tex] 3x = 48 [/tex]
[tex] x = \frac{48}{3} [/tex]
[tex] x = 16 [/tex]

To make 5 smoothies that have the same ratio of apple juice to orange juice as 1 smoothie does, how much apple juice and orange juice should Sarah use? Explain.
Answer:
40 Apple juice and 20 Orange juice
Step-by-step explanation:
From the diagram, you know that 4 OJ makes one drink, so to make 5 drinks, you need 5 times that, or 20 OJ. You can also see that you need twice as much AJ as OJ, so that means you need 40 AJ.
*OJ = Orange juice and AJ = Apple juice

A building has two sizes of apartments, small and regular. The ratio of small apartments to regular apartments is 14 to 6. What percent of apartments in the building are small?
Answer:
[tex]\%Percent = 70\%[/tex]
Step-by-step explanation:
Given
Represent Small Apartments with S and the Regular ones with R
[tex]S:R = 14:6[/tex]
Required
Determine the percentage of small buildings
This is calculated as thus:
[tex]\%Percent = \frac{S}{S + R} * 100\%[/tex]
Substitute values for S and R
[tex]\%Percent = \frac{14}{14 + 6} * 100\%[/tex]
[tex]\%Percent = \frac{14}{20} * 100\%[/tex]
[tex]\%Percent = \frac{14* 100\%}{20}[/tex]
[tex]\%Percent = \frac{1400\%}{20}[/tex]
[tex]\%Percent = 70\%[/tex]
Hence, the percentage if the small apartments is 70%
Note that if we're to calculate the percentage of the regular ones, the formula would have been:
[tex]\%Percent = \frac{R}{S + R} * 100\%[/tex]
A portrait has dimensions of 30“ x 60“ and is surrounded by a frame of uniform width. If the total area (Portrait plus frame) is 2584 square inches, find the width of the frame
Answer:
The width of the is 4 inches
Step-by-step explanation:
Assume that the width of the frame is x
∵ The width of the fame is x inches
→ That means each dimension will increase by 2x ⇒ x from each side
∵ The portrait has dimensions of 30“ x 60“
∴ Its dimensions including the frame = (30 + 2x) × (60 + 2x)
∴ The total area of the portrait plus frame = (30 + 2x)(60 + 2x)
→ Multiply the brackets
∵ (30 + 2x)(60 + 2x) = 30(60) + 30(2x) + 2x(60) + (2x)(2x)
∴ (30 + 2x)(60 + 2x) = 1800 + 60x + 120x + 4x²
→ Add the like terms
∴ (30 + 2x)(60 + 2x) = 1800 + 180x + 4x²
∴ The total area of the portrait plus frame = 4x² + 180x + 1800
∵ The total area of the portrait plus frame = 2584 square inches
→ Equate the two right sides of the area
∴ 4x² + 180x + 1800 = 2584
→ Subtract 2584 from both sides
∴ 4x² + 180x + 1800 - 2584 = 0
→ Add the like terms in the left side
∴ 4x² + 180x - 784 = 0
→ Divide all terms by 4 to simplify
∴ x² + 45x - 196 = 0
→ Factorize it to find the value of x
∵ x² + 45x - 196 = (x - 4)(x + 49)
→ Equate the right side by 0
∴ (x - 4)(x + 49) = 0
→ Equate each factor by 0
∵ x - 4 = 0
→ Add 4 to both sides to find x
∴ x = 4
∵ x + 49 = 0
→ Subtract 49 from both sides to find x
∴ x = -49 ⇒ refused it x can not be -ve (no negative dimensions)
∴ The width of the is 4 inches
the is factoring quadratics with a leading coefficient: 5x to the 2 power - 14x + 8
Answer:
The factorization of [tex]5x^2-14x+8[/tex] is (5x-4)(x-2)
Step-by-step explanation:
Given quadratic polynomial is:
[tex]5x^2-14x+8[/tex]
To factor a quadratic polynomial with leading co-efficient has to be factorized, the leading co-efficient and the constant are multiplied and pairs(a,b) of the product are made so that their sum or subtraction is equal to the co-efficient of x
We get 40 by multiplying 8 and 5
And the pair we get are: 10 and 4
[tex]=5x^2-10x-4x+8\\=5x(x-2)-4(x-2)\\=(5x-4)(x-2)[/tex]
Hence,
The factorization of [tex]5x^2-14x+8[/tex] is (5x-4)(x-2)

On average, Tony the turtle completes a 15-foot course in 1 minute, and Antonio the turtle completes an 18-foot course in 1 minute. If Tony and Antonio both start at the same time and travel in the same direction, how far apart will the turtles be after 5 minutes?(1 point)
75 feet
15 feet
90 feet
165 feet
Answer:
15 feet.
Step-by-step explanation:
Tony's speed = 15 ft/min.
Antonio's = 18 feet /min.
So in 5 minutes Tony travels 5*15 = 75 feet and Antonio travels 5*18 = 90 feet.
So the answer is 90-75 = 15 feet.
